Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Description of Business Nuvve Holding Corp., a Delaware corporation headquartered in San Diego, California (the “Company” or “Nuvve”), was founded on November 10, 2020 under the laws of the state of Delaware. On March 19, 2021, the Company (at the time known as NB Merger Corp.) acquired the outstanding shares of Nuvve Corporation (“Nuvve Corp.”), and the Company changed its name to Nuvve Holding Corp. Structure of the Company Nuvve has two wholly owned subsidiaries, Nuvve Corp. and Nuvve Co (Nuvve Japan). Nuvve Corp. has three wholly owned subsidiaries: (1) Nuvve Denmark ApS, (“Nuvve Denmark”), a company registered in Denmark, (2) Nuvve SaS, a company registered in France, and (3) Nuvve LTD, a company registered in United Kingdom. In March 2020, following the establishment of its investment in Dreev in 2019 (Note 6), the Company ceased operations of its subsidiary, Nuvve SaS in France. The two employees of Nuvve SaS resigned from the Company in March 2020 and were concurrently hired by Dreev. Financial results for Nuvve SaS are included in the Company’s financial results through the cessation of operations. On August 4, 2021, the Company formed Levo Mobility LLC, a Delaware limited liability company ("Levo"), with Stonepeak Rocket Holdings LP, a Delaware limited partnership (Stonepeak"), and Evolve Transition Infrastructure LP, a Delaware limited partnership ("Evolve"). Levo is a consolidated a entity of the Company. Please see Note 2 for the principles of consolidation. Levo is a sustainable infrastructure company focused on rapidly advancing the electrification of transportation by funding V2G-enabled EV fleet deployments. Levo utilizes Nuvve’s V2G technology and committed capital from Stonepeak and Evolve to offer Fleet-as-a-Service for school buses, last-mile delivery, ride hailing and ride sharing, municipal services, and more to eliminate the primary barriers to EV fleet adoption including large upfront capital investments and lack of expertise in securing and managing EVs and associated charging infrastructure. Levo's turnkey solution simplifies and streamlines electrification, can lower the total cost of EV operation for fleet owners, and support the grid when the EVs are not in use. For a fixed monthly payment with no upfront cost, Levo will provide the EVs, such as electric school buses, charging infrastructure powered by Nuvve’s V2G platform, EV and charging station maintenance, energy management, and technical advice. Levo will initially focus on electrifying school buses, providing associated charging infrastructure, and delivering V2G services to enable safer and healthier transportation for children while supporting carbon dioxide emission reduction, renewable energy integration, and improved grid resiliency.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies For a detailed discussion about the Company’s significant accounting policies, see Note 2, “ Summary of Significant Accounting Policies ,” in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”). During the three months ended March 31, 2022, there were no significant updates made to the Company’s significant accounting policies. Basis of Presentation The accompanying unaudited (i) condensed consolidated balance sheet as of December 31, 2021, which has been derived from audited financial statements, and (ii) the unaudited interim condensed financial statements have been prepared in accordance pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Therefore, it is suggested that these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes in the 2021 Form 10-K, filed with the Securities and Exchange Commission ("SEC") on March 31, 2022. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, cash flows, and stockholders’ equity for the interim periods, but are not necessarily indicative of the results to be anticipated for the full year 2022 or any future period. In accordance with Accounting Standards Codification ("ASC") 205-40, Presentation of Financial Statements - Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the that the consolidated financial statements are issued. Since inception, the Company has incurred recurring losses and negative cash flows from operations since inception and has an accumulated deficit of $56.4 million as of March 31, 2022. Nuvve incurred net losses of approximately $9.1 million for the quarter ended March 31, 2022, and $27.2 million and $4.7 million for the years ended December 31, 2021, and 2020, respectively. As of March 31, 2022, Nuvve had a cash balance, working capital, and stockholders’ equity of $23.7 million, $28.8 million and $71.4 million, respectively. The Company continues to expect to generate operating losses and negative cash flows and may need additional funding to support its planned operating activities through profitability. The transition to profitability is dependent upon the successful expanded commercialization of the Company's GIVe platform and the achievement of a level of revenues adequate to support its cost structure. The Company expects its cash and cash equivalents as of May 12, 2022 will be sufficient to fund current planned operations for at least the next twelve months from the date of issuance of these consolidated financial statements. Management's expectations with respect to its ability to fund current planned operations is based on estimates that are subject to risks and uncertainties. Actual results could be different from management's estimates and should actual results be less favorable than these estimates management would ultimately need to take corrective steps to improve future operating results and its financial condition. Principles of Consolidation The condensed consolidated financial statements include the accounts and operations of the Company, its wholly owned subsidiaries and its consolidated variable interest entity. All intercompany accounts and transactions have been eliminated upon consolidation. Variable Interest Entities Pursuant to the consolidation guidance, the Company first evaluates whether it holds a variable interest in an entity in which it has a financial relationship and, if so, whether or not that entity is a variable interest entity ("VIE"). A VIE is an entity with insufficient equity at risk for the entity to finance its activities without additional subordinated financial support or in which equity investors lack the characteristics of a controlling financial interest. If an entity is determined to be a VIE, the Company evaluates whether the Company is the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. The Company concludes that it is the primary beneficiary and consolidates the VIE if the Company has both (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance, and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company formed Levo with Stonepeak and Evolve, in which the Company owns 51% of Levo's common units. The Company has determined that Levo is a VIE in which the Company is the primary beneficiary. Accordingly, the Company consolidates Levo and records a non-controlling interest for the share of the entity owned by Stonepeak and Evolve. Assets and Liabilities of Consolidated VIEs The Company's condensed consolidated financial statements include the assets, liabilities and results of operations of VIEs for which the Company is the primary beneficiary. The other equity holders’ interests are reflected in "Net loss attributable to non-controlling interests" in the condensed consolidated statements of operations and "Non-controlling interests" in the condensed consolidated balance sheets. See Note 18 for details of non-controlling interests. The Company began consolidating the assets, liabilities and results of operations of Levo during the quarter ended March 31, 2022. The creditors of the consolidated VIE do not have recourse to the Company other than to the assets of the consolidated VIEs. The following table summarizes the carrying amounts of Levo assets and liabilities included in the Company’s condensed consolidated balance sheets at March 31, 2022: March 31, 2022 Assets Cash $ 28,257 Deferred financing costs 3,920,323 Total Assets $ 3,948,580 Liabilities and Mezzanine Equity Accrued expenses $ 236,775 Derivative liability - non-controlling redeemable preferred shares 458,476 Total Liabilities $ 695,251 Redeemable Non-Controlling Interest - Mezzanine Equity Redeemable non-controlling interest represents the shares of the preferred stock issued by Levo to Stonepeak and Evolve (the "preferred shareholders") who own 49% of Levo common units. The preferred stock is not mandatorily redeemable or currently redeemable, but it could be redeemable with the passage of time at the election of Levo, the preferred shareholders or a trigger event as defined in the preferred stock agreement. As a result of the contingent put right available to the preferred shareholders, the redeemable non-controlling interests in Levo are classified outside of permanent equity in the Company’s unaudited condensed consolidated balance sheets as mezzanine equity. The initial carrying value of the redeemable non-controlling interest is reported at the initial proceeds received on issuance date, reduced by the fair value of embedded derivatives resulting in an adjusted initial carrying value. The adjusted initial carrying value is further adjusted for the accretion of the difference with the redemption price value using the effective interest method. The accretion amount is a deemed dividend recorded against retained earnings or, in its absence, to additional-paid-in-capital. The carrying amount of the redeemable non-controlling interest is measured at the higher of the carrying amount adjusted each reporting period for income (or loss) attributable to the non-controlling interest, or the carrying amount adjusted each reporting period by the accretion amount. See Note 18 for details. Non-controlling interests The Company presents non-controlling interests as a component of equity on its condensed consolidated balance sheets and reports the portion of its earnings or loss for non-controlling interest as net earnings or loss attributable to non-controlling interests in the condensed consolidated statements of operations. Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits emerging growth companies (“EGC”) to delay complying with new or revised financial accounting standards that do not yet apply to private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act). The Company qualifies as an EGC. The JOBS Act provides that an EGC can elect to opt-out of the extended transition period and comply with the requirements that apply to non-EGCs, but any such election to opt-out is irrevocable. The Company has elected not to opt-out of such an extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an EGC, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This different adoption timing may make a comparison of the Company’s financial statements with another public company which is neither an EGC nor an EGC that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. COVID-19 The novel coronavirus (COVID-19) which was declared a pandemic in March 2020, and the related restrictive measures such as travel restrictions, quarantines, and shutdowns, has negatively impacted the global economy. As national and local governments in different countries ease COVID-19 restrictions, and vaccines are distributed and rolled out successfully, we continue to see improved economic trends. However, COVID-19 and actions taken to mitigate its spread have had and are expected to continue to have an adverse impact on the economies and financial markets of many countries, including the geographical area in which the Company operates. The Company continues to monitor the situation closely but, at this time, is unable to predict the cumulative impact, both in terms of severity and duration, that the coronavirus pandemic has and will have on its business, operating results, cash flows and financial condition, and it could be material if the current circumstances continue to exist for a prolonged period of time. In addition to any direct impact on Nuvve’s business, it is reasonably possible that the estimates made by management in preparing Nuvve’s financial statements have been, or will be, materially and adversely impacted in the near term as a result of the on-going COVID-19 conditions. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions made by management include the impairment of intangible assets, the net realizable value of inventory, the fair value of share-based payments, the fair value of notes payable conversion options, revenue recognition, the fair value of warrants, and the recognition and disclosure of contingent liabilities. Management evaluates its estimates on an ongoing basis. Actual results could materially vary from those estimates. Cash and Restricted Cash The Company maintains cash balances that can, at times, exceed amounts insured by the Federal Deposit Insurance Corporation, which is up to $250,000. The Company has not experienced any losses in these accounts and believes it is not exposed to any significant credit risk in this area. Concentrations of Credit Risk At March 31, 2022 and December 31, 2021, the financial instruments which potentially expose the Company to concentration of credit risk consist of cash in financial institutions (in excess of federally insured limits) and trade receivables. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: For the three months ended March 31, 2022 and 2021, one customer accounted for 72.8%, and two customers in aggregate accounted for 49.9% of revenue, respectively. During the three months ended March 31, 2022 and 2021 , the Company's top five customers accounted for approximately 87.5% and 71.4%, respectively, o f the Company’s total revenue. At March 31, 2022 , two customers in aggregate accounted for 35.7% of accounts receivable. At December 31, 2021 , two customers in aggregate accounted for 32.2% of accounts receivable. Approximately 58.7% and 56.0% of the Company’s trade accounts receivable balance was with five customers at March 31, 2022 and December 31, 2021 , respectively. The Company estimates its maximum credit risk for accounts receivable at the amount recorded on the balance sheet. The trade accounts receivables are generally short-term and all probable bad debt losses have been appropriately considered in establishing the allowance for doubtful accounts. Deferred Financing Costs Deferred financing costs consist of direct and incremental costs incurred and fees paid for a commitment to obtain financing. As the commitment amount is funded, the carrying amount of the deferred financing costs is reduced and the amount is charged to additional-paid-in-capital. The deferred financing cost will be impaired if it becomes probable that funding of the commitment amount will not occur. Recently adopted accounting pronouncements None. Recently issued accounting pronouncements not yet adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires, among other things, the use of a new current expected credit loss ("CECL") model in determining the allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable, and notes receivable. The CECL model requires that an entity estimate its lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. Entities will also be required to disclose information about how the entity developed the allowances, including changes in the factors that influenced its estimate of expected credit losses and the reasons for those changes. This update is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

The fair value of the level 3 derivative liability - non-controlling redeemable preferred shares are estimated at March 31, 2022 using the M onte Carlo Simulation model which used the following inputs: terms range from 3.0 years to 7.0 years, risk free rate of 2.4%, no dividends, volatility of 56.0% and probability of redemptions triggered of 75.0%. There were no transfers between Level 1 and Level 2 of the fair value hierarchy in 2022 and 2021. Cash, accounts receivable, accounts payable, and accrued expenses are generally carried on the cost basis, which management believes approximates fair value due to the short-term maturity of these instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Liability - Non-Controlling Redeemable Preferred Stock	Derivative Liability - Non-Controlling Redeemable Preferred Stock The Company has determined that the redemption features embedded in the non-controlling redeemable preferred stock is required to be accounted for separately from the redeemable preferred stock as a derivative liability. Separation of the redemption features as a derivative liability is required because its economic characteristics and risks are considered more akin to a debt instrument, and therefore, not considered to be clearly and closely related to the economic characteristics of the redeemable preferred stock. The economic characteristics of the redemption features are considered more akin to an debt instrument because the minimum redemption value could be greater than the face amount, the redemption features are contingently exercisable, and the shares carry a fixed mandatory dividend. Accordingly, the Company has recorded an embedded derivative liability representing the estimated fair value of the right of the holders to exercise their redemption option upon the occurrence of a redemption event. The embedded derivative liability is adjusted to reflect fair value at each period end with changes in fair value recorded in the “Change in fair value of derivative liability” financial statement line item of the company’s consolidated statements of operations. For additional information on the non-controlling redeemable preferred stock, see Note 18 .

Additionally, see Note 19, “Levo Mobility LLC Entity,” in the Notes to Consolidated Financial Statements included in the Company’s 2021 Form 10-K for a detailed discussion of the Company’s Stonepeak and Evolve Warrants and Securities Purchase agreement, and Levo definitive agreements. Warrants - Stonepeak and Evolve On May 17, 2021, in connection with the signing of a letter of agreement, as reference above, relating to the formation of a venture, Levo Mobility LLC (the "Letter Agreement"), the Company issued to Stonepeak and Evolve a ten years warrants to purchase common stock (allocated 90% to Stonepeak and 10% to Evolve).

The grant-date fair value of the warrants issued to Stonepeak and Evolve were; series B $12.8 million, series C $5.6 million, series D $4.8 million, series E $3.8 million and series F $3.2 million. The fair values of the warrants are recorded in the consolidated balance sheets in additional-paid-in capital in stockholders' equity as the warrants are indexed to the Company’s common stock and meet the conditions for equity classification, and deferred financing costs. The carrying amount of the deferred financing costs is reduced as the commitment amount is funded, and the reduction amount is charged to additional-paid-in capital. As of March 31, 2022, the commitment funded of $3.2 million has reduced the deferred financing costs, and charged to additional-paid-in capital. In connection with the signing of the Letter Agreement, the Company issued to Stonepeak and Evolve the following ten years warrants to purchase common stock (allocated 90% to Stonepeak and 10% to Evolve): • Series B warrants to purchase 2,000,000 shares of the Company’s common stock, at an exercise price of $10.00 per share, which are fully vested upon issuance, • Series C warrants to purchase 1,000,000 shares of the Company’s common stock, at an exercise price of $15.00 per share, which are vested as to 50% of the shares upon issuance and vest as to the remaining 50% when Levo has entered into contracts with third parties for $125 million in aggregate capital expenditures, • Series D warrants to purchase 1,000,000 shares of the Company’s common stock, at an exercise price of $20.00 per share, which are vested as to 50% of the shares upon issuance and vest as to the remaining 50% when Levo has entered into contracts with third parties for $250 million in aggregate capital expenditures, • Series E warrants to purchase 1,000,000 shares of the Company’s common stock, at an exercise price of $30.00 per share, which are vested as to 50% of the shares upon issuance and vest as to the remaining 50% when Levo has entered into contracts with third parties for $375 million in aggregate capital expenditures, and • Series F warrants to purchase 1,000,000 shares of the Company’s common stock, at an exercise price of $40.00 per share, which are vested as to 50% of the shares upon issuance and vest as to the remaining 50% when Levo has entered into contracts with third parties for $500 million in aggregate capital expenditures. The warrants may be exercised at any time on or after the date that is 180 days after the applicable vesting date. Warrants - Public and Private In connection with its initial public offering on February 19, 2020, Newborn sold 5,750,000 units, which included one warrant to purchase Newborn’s common stock (the “Public Warrants”). Also, on February 19, 2020, NeoGenesis Holding Co., Ltd., Newborn’s sponsor (“the Sponsor”), purchased an aggregate of 272,500 private units, each of which included one warrant (the “Private Warrants”), which have the same terms as the Public Warrants. Upon completion of the merger between Nuvve and Newborn, the Public Warrants and Private Warrants were automatically converted to warrants to purchase Common Stock of the Company. The terms of the Private Warrants are identical to the Public Warrants as described above, except that the Private Warrants are not redeemable so long as they are held by the Sponsor or its permitted transferees. Concurrently with the execution of the Merger Agreement on November 11, 2020, Newborn entered into subscription agreements with certain accredited investors pursuant to which the investors agreed to purchase 1,425,000 of Newborn’s common stock, at a purchase price of $10.00 per share, for an aggregate purchase price of $14,250,000 (the PIPE). Upon closing of the PIPE immediately prior to the closing of the Business Combination, the PIPE investors also received 1.9 PIPE Warrants to purchase the Company’s Common Stock for each share of Common Stock purchased. The PIPE Warrants are each exercisable for one-half of a common share at $11.50 per share and have the same terms as described above for the Public Warrants. The PIPE investors received demand and piggyback registration rights in connection with the securities issued to them. The following table is a summary of the number of shares of the Company’s Common Stock issuable upon exercise of warrants outstanding at March 31, 2022 (there were no warrants outstanding at December 31, 2021): Number of Number of Exercise Expiration Public Warrants 2,875,000 2,875,000 $11.50 March 19, 2026 Private Warrants 136,250 136,250 $11.50 March 19, 2026 PIPE Warrants 1,353,750 1,353,750 $11.50 March 19, 2026 Stonepeak/Evolve Warrants - series B 2,000,000 2,000,000 $10.00 May 17, 2031 Stonepeak/Evolve Warrants - series C 1,000,000 500,000 $15.00 May 17, 2031 Stonepeak/Evolve Warrants - series D 1,000,000 500,000 $20.00 May 17, 2031 Stonepeak/Evolve Warrants - series E 1,000,000 500,000 $30.00 May 17, 2031 Stonepeak/Evolve Warrants - series F 1,000,000 500,000 $40.00 May 17, 2031 10,365,000 8,365,000 Because the Private Warrants have dissimilar terms with respect to the Company’s redemption rights depending on the holder of the Private Warrants, the Company determined that the Private Warrants are required to be carried as a liability in the condensed consolidated balance sheet at fair value, with changes in fair value recorded in the condensed consolidated statement of operations. The Private Warrants are reflected as a liability in the condensed consolidated balance sheet as of March 31, 2022 in the amount of $433,000 and the change in the fair value of the Private Warrant for the three months ended March 31, 2022 of is reflected as a gain of $433,000, in the condensed consolidated statement of operations. Unit Purchase Option On February 19, 2020, Newborn sold to the underwriters of its initial public offering for $100, a unit purchase option ("UPO") to purchase up to a total of 316,250 units at $11.50 per unit (or an aggregate exercise price of $3,636,875) commencing on the date of Newborn's initial business combination, March 19, 2021, and expiring February 13, 2025. Each unit issuable upon exercise of the UPO consists of one and one-tenth of a share of the Company's common stock and one warrant to purchase one share of the Company's common stock at the exercise price of $11.50 per share. The warrant has the same terms as the Public Warrant. In no event will the Company be required to net cash settle the exercise of the UPO or the warrants underlying the UPO. The holders of the unit purchase option have demand and "piggy back" registration rights for periods of five ASC 815-40, Derivatives and Hedging-Contracts in an Entity’s Own Equity, as the UPO is indexed to the Company’s common stock and meets the conditions for equity classification. Securities Purchase Agreement On May 17, 2021, in connection with the signing of a letter of agreement relating to the formation of a venture, Levo Mobility LLC, the Company entered into a Securities Purchase Agreement with Stonepeak and Evolve which provide them from time to time between November 13, 2021 and November 17, 2028, in their sole discretion, to purchase up to an aggregate of $250 million in shares of the Company’s common stock at a purchase price of $50.00 per share (allocated 90% to Stonepeak and 10% to Evolve). See below f or details. The grant-date fair value of the Securities Purchase Agreement to purchase shares of the Company’s common stock was $12.6 million, and is recorded in the condensed consolidated balance sheet as equity in additional-paid-in capital as it is indexed to the Company’s common stock and meets the conditions for equity classification, and deferred financing costs. The carrying amount of the deferred financing costs is reduced as the commitment amount is funded, and the amount is charged to additional-paid-in capital. In connection with the signing of the Letter Agreement, as reference above, the Company also entered into a Securities Purchase Agreement (the “SPA”) and a Registration Rights Agreement (the “RRA”) with Stonepeak and Evolve. • Under the SPA, from time to time between November 13, 2021 and November 17, 2028, Stonepeak and Evolve may elect, in their sole discretion, to purchase up to an aggregate of $250 million in shares of the Company’s common stock at a purchase price of $50.00 per share (allocated 90% to Stonepeak and 10% to Evolve). The SPA includes customary representations and warranties and closing conditions and customary indemnification provisions. In addition, Stonepeak and Evolve may elect to purchase shares under the SPA on a cashless basis in the event of a change of control of the Company.

Stock Option Plan	Stock Option Plan In 2010, the Company adopted the 2010 Equity Incentive Plan (the “2010 Plan”), which provides for the grant of restricted stock awards, stock options, and other share-based awards to employees, consultants, and directors. In November 2020, the Company’s Board of Directors extended the term of the 2010 Plan to July 1, 2021. In 2021, the Company adopted the 2020 Equity Incentive Plan (the “2020 Plan”), which provides for the grant of restricted stock awards, incentive and non-statutory stock options, and other share-based awards to employees, consultants, and directors. As of March 31, 2022, there is an aggregate of 3,300,000 common shares reserved for issuance under the 2020 Plan. All options granted to date have a ten years contractual life and vesting terms of four years. In general, vested options expire if not exercised at termination of service. As of March 31, 2022, a total of 1,321,374 shares of common stock remained available for future issuance under the 2020 Plan.

The following assumptions were used in the Black-Scholes model to calculate the fair value of stock options granted for the three months ended March 31, 2022 for the 2010 Plan and the 2020 Plan. 2010 Plan 2020 Plan Expected life of options (in years) (1) 6.1 6.1 Dividend yield (2) 0 % 0 % Risk-free interest rate (3) 2.00 % 2.00 % Volatility (4) 54.4 % 54.4 % __________________ (1) The expected life of options is the average of the contractual term of the options and the vesting period. (2) No cash dividends have been declared on the Company’s common stock since the Company’s inception, and the Company currently does not anticipate declaring or paying cash dividends over the expected life of the options. (3) The risk-free interest rate is based on the yields on U.S. Treasury debt securities with maturities approximating the estimated life of the options. (4) Volatility is estimated by management. As the Company has been a private company for most of its existence, there is not enough historical volatility data related to the Company’s Common stock as a public entity. Therefore, this estimate is based on the average volatility of certain public company peers within the Company’s industry.

Income Taxes	Income Taxes Three Months Ended March 31, 2022 2021 Income tax (benefit) expense $ — $ — Effective tax rate 0.0 % (0.1) % The effective tax rate used for interim periods is the estimated annual effective tax rate, based on current estimate of full year results, except that taxes related to specific events, if any, are recorded in the interim period in which they occur. The effective tax rate differed from the U.S. federal statutory tax rate primarily due to operating losses that receive no tax benefit as a result of a valuation allowance recorded for such losses. The Company accounts for income taxes in accordance with ASC Topic 740, Income Taxes (“ASC 740”). Under the provisions of ASC 740, management is required to evaluate whether a valuation allowance should be established against its deferred tax assets. The Company currently has a full valuation allowance against its deferred tax assets. As of each reporting date, the Company’s management considers new evidence, both positive and negative, that could impact management’s view with regard to future realization of deferred tax assets. For the three months ended March 31, 2022, there was no material change from the year ended December 31, 2021 in the amount of the Company’s deferred tax assets that are not considered to be more likely than not to be realized in future years.

Noncontrolling Interest [Abstract]
Non-Controlling Interest	Non-Controlling Interest For entities that are consolidated, but not 100% owned, a portion of the net income or loss and corresponding equity is allocated to owners other than the Company. The aggregate of the net income or loss and corresponding equity that is not owned by the Company is included in non-controlling interests in the condensed consolidated financial statements. Non-controlling interests are presented outside as a separate component of stockholders’ equity on the Company’s condensed consolidated Balance Sheets. The primary components of non-controlling interests are separately presented in the Company’s condensed consolidated statements of changes in stockholders’ equity to clearly distinguish the interest in the Company and other ownership interests in the consolidated entities. Net income or loss includes the net income or loss attributable to the holders of non-controlling interests on the Company’s condensed consolidated statements of operations. Net income or loss is allocated to non-controlling interests in proportion to their relative ownership interests. Levo Series B Redeemable Preferred Stock Levo is authorized to issue 1,000,000 shares of series B preferred stock at no par value. The Series B Preferred Stock (a) pays a dividend, when, as and if declared by Levo's Board of Directors, of 8.0% per annum of the stated value per share, payable quarterly in arrears, (b) has an initial stated value of $1,000 per share, and dividends are paid in cash. Levo accrues for undeclared and unpaid dividends as they are payable in accordance with the terms of the Certificate of Designations filed with the Secretary of State of the State of Delaware. At March 31, 2022, Levo had accrued preferred dividends of $126,775 on 3,138 issued and outstanding shares of Series B Preferred Stock. Series B Preferred Stock is not a participating or convertible securities. Series B Preferred Stock is not currently redeemable but it could be redeemable with the passage of time at the election of Levo or the preferred shareholders or upon the occurrence of a trigger event as defined in the preferred stock agreement. Since the redeemable preferred stock may be redeemed by the preferred shareholders or upon the occurrence of a trigger event that is not solely within the control of Levo, but is not mandatorily redeemable; therefore, based on its characteristics, Levo has classified the Series B Preferred Stock as mezzanine equity. At March 31, 2022, Series B Preferred Stock consisted of the following: Shares Authorized Shares Issued and Outstanding Stated Value per Share Initial Carrying Value Accrued Preferred Dividends Liquidation Preference 1,000,000 3,138 $ 1,000 $ 3,138,000 $ 126,775 $ 3,264,775 The Company has determined that the redemption features embedded in the non-controlling redeemable preferred stock is required to be accounted for separately from the redeemable preferred stock as a derivative liability. See Note 5 for detail disclosure of the derivative liability. The redeemable preferred stock has been classified as mezzanine equity and initially recognized at fair value of $3,138,000, the proceeds on the date of issuance. This amount has been further reduced by —, the fair value of the embedded derivative liability at date of issuance, resulting in an adjusted initial value of $3,138,000. Levo is accreting the difference between the adjusted carrying initial value and the redemption price value over the seven-year period from date of issuance of August 4, 2021 through July 4, 2028 (the date at which the preferred shareholders have the unconditional right to redeem the shares, deemed to be the earliest likely redemption date) using the effective interest method. The accretion to the carrying value of the redeemable preferred stock is treated as a deemed dividend, recorded as a charge to retained earnings of Levo. During the quarter ended March 31, 2022, Levo accreted $161,466 resulting in the carrying value of the the redeemable preferred stock of $3,046,892. The following table summarizes Levo non-controlling interests presented as a separate component of stockholders’ equity on the Company’s condensed consolidated balance sheets at March 31, 2022: March 31, 2022 Add: net loss attributable to non-controlling interests as of March 31, 2022 $ (100,933) Less: dividends paid to non-controlling interests as of March 31, 2022 64,015 Less: Preferred share accretion adjustment 161,466 Non-controlling interests $ (326,414) The following table summarizes Levo non-controlling interests presented as a separate component of the Company’s condensed consolidated statements of operations as of March 31, 2022: Three Months Ended Net loss attributable to non-controlling interests $ (100,933) Redeemable Non-controlling Interest Reconciliation — Mezzanine Equity Three Months Ended Beginning balance - December 31, 2021 $ 2,885,426 Preferred share Accretion adjustment 161,466 Ending balance - March 31, 2022 $ 3,046,892

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited (i) condensed consolidated balance sheet as of December 31, 2021, which has been derived from audited financial statements, and (ii) the unaudited interim condensed financial statements have been prepared in accordance pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Therefore, it is suggested that these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes in the 2021 Form 10-K, filed with the Securities and Exchange Commission ("SEC") on March 31, 2022. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, cash flows, and stockholders’ equity for the interim periods, but are not necessarily indicative of the results to be anticipated for the full year 2022 or any future period. In accordance with Accounting Standards Codification ("ASC") 205-40, Presentation of Financial Statements - Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the that the consolidated financial statements are issued. Since inception, the Company has incurred recurring losses and negative cash flows from operations since inception and has an accumulated deficit of $56.4 million as of March 31, 2022. Nuvve incurred net losses of approximately $9.1 million for the quarter ended March 31, 2022, and $27.2 million and $4.7 million for the years ended December 31, 2021, and 2020, respectively. As of March 31, 2022, Nuvve had a cash balance, working capital, and stockholders’ equity of $23.7 million, $28.8 million and $71.4 million, respectively. The Company continues to expect to generate operating losses and negative cash flows and may need additional funding to support its planned operating activities through profitability. The transition to profitability is dependent upon the successful expanded commercialization of the Company's GIVe platform and the achievement of a level of revenues adequate to support its cost structure. The Company expects its cash and cash equivalents as of May 12, 2022 will be sufficient to fund current planned operations for at least the next twelve months from the date of issuance of these consolidated financial statements. Management's expectations with respect to its ability to fund current planned operations is based on estimates that are subject to risks and uncertainties. Actual results could be different from management's estimates and should actual results be less favorable than these estimates management would ultimately need to take corrective steps to improve future operating results and its financial condition.
Principles of Consolidation	Principles of ConsolidationThe condensed consolidated financial statements include the accounts and operations of the Company, its wholly owned subsidiaries and its consolidated variable interest entity. All intercompany accounts and transactions have been eliminated upon consolidation.
Variable Interest Entities	Variable Interest Entities Pursuant to the consolidation guidance, the Company first evaluates whether it holds a variable interest in an entity in which it has a financial relationship and, if so, whether or not that entity is a variable interest entity ("VIE"). A VIE is an entity with insufficient equity at risk for the entity to finance its activities without additional subordinated financial support or in which equity investors lack the characteristics of a controlling financial interest. If an entity is determined to be a VIE, the Company evaluates whether the Company is the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and economics. The Company concludes that it is the primary beneficiary and consolidates the VIE if the Company has both (i) the power to direct the activities of the VIE that most significantly influence the VIE's economic performance, and (ii) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. The Company formed Levo with Stonepeak and Evolve, in which the Company owns 51% of Levo's common units. The Company has determined that Levo is a VIE in which the Company is the primary beneficiary. Accordingly, the Company consolidates Levo and records a non-controlling interest for the share of the entity owned by Stonepeak and Evolve. Assets and Liabilities of Consolidated VIEs The Company's condensed consolidated financial statements include the assets, liabilities and results of operations of VIEs for which the Company is the primary beneficiary. The other equity holders’ interests are reflected in "Net loss attributable to non-controlling interests" in the condensed consolidated statements of operations and "Non-controlling interests" in the condensed consolidated balance sheets. See Note 18 for details of non-controlling interests. The Company began consolidating the assets, liabilities and results of operations of Levo during the quarter ended March 31, 2022.
Noncontrolling Interest	Redeemable Non-Controlling Interest - Mezzanine Equity Redeemable non-controlling interest represents the shares of the preferred stock issued by Levo to Stonepeak and Evolve (the "preferred shareholders") who own 49% of Levo common units. The preferred stock is not mandatorily redeemable or currently redeemable, but it could be redeemable with the passage of time at the election of Levo, the preferred shareholders or a trigger event as defined in the preferred stock agreement. As a result of the contingent put right available to the preferred shareholders, the redeemable non-controlling interests in Levo are classified outside of permanent equity in the Company’s unaudited condensed consolidated balance sheets as mezzanine equity. The initial carrying value of the redeemable non-controlling interest is reported at the initial proceeds received on issuance date, reduced by the fair value of embedded derivatives resulting in an adjusted initial carrying value. The adjusted initial carrying value is further adjusted for the accretion of the difference with the redemption price value using the effective interest method. The accretion amount is a deemed dividend recorded against retained earnings or, in its absence, to additional-paid-in-capital. The carrying amount of the redeemable non-controlling interest is measured at the higher of the carrying amount adjusted each reporting period for income (or loss) attributable to the non-controlling interest, or the carrying amount adjusted each reporting period by the accretion amount. See Note 18 for details. Non-controlling interests The Company presents non-controlling interests as a component of equity on its condensed consolidated balance sheets and reports the portion of its earnings or loss for non-controlling interest as net earnings or loss attributable to non-controlling interests in the condensed consolidated statements of operations. For entities that are consolidated, but not 100% owned, a portion of the net income or loss and corresponding equity is allocated to owners other than the Company. The aggregate of the net income or loss and corresponding equity that is not owned by the Company is included in non-controlling interests in the condensed consolidated financial statements. Non-controlling interests are presented outside as a separate component of stockholders’ equity on the Company’s condensed consolidated Balance Sheets. The primary components of non-controlling interests are separately presented in the Company’s condensed consolidated statements of changes in stockholders’ equity to clearly distinguish the interest in the Company and other ownership interests in the consolidated entities. Net income or loss includes the net income or loss attributable to the holders of non-controlling interests on the Company’s condensed consolidated statements of operations. Net income or loss is allocated to non-controlling interests in proportion to their relative ownership interests.
Emerging Growth Company	Emerging Growth Company Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) permits emerging growth companies (“EGC”) to delay complying with new or revised financial accounting standards that do not yet apply to private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act). The Company qualifies as an EGC. The JOBS Act provides that an EGC can elect to opt-out of the extended transition period and comply with the requirements that apply to non-EGCs, but any such election to opt-out is irrevocable. The Company has elected not to opt-out of such an extended transition period, which means that when a standard
COVID-19	COVID-19 The novel coronavirus (COVID-19) which was declared a pandemic in March 2020, and the related restrictive measures such as travel restrictions, quarantines, and shutdowns, has negatively impacted the global economy. As national and local governments in different countries ease COVID-19 restrictions, and vaccines are distributed and rolled out successfully, we continue to see improved economic trends. However, COVID-19 and actions taken to mitigate its spread have had and are expected to continue to have an adverse impact on the economies and financial markets of many countries, including the geographical area in which the Company operates. The Company continues to monitor the situation closely but, at this time, is unable to predict the cumulative impact, both in terms of severity and duration, that the coronavirus pandemic has and will have on its business, operating results, cash flows and financial condition, and it could be material if the current circumstances continue to exist for a prolonged period of time. In addition to any direct impact on Nuvve’s business, it is reasonably possible that the estimates made by management in preparing Nuvve’s financial statements have been, or will be, materially and adversely impacted in the near term as a result of the on-going COVID-19 conditions.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions made by management include the impairment of intangible assets, the net realizable value of inventory, the fair value of share-based payments, the fair value of notes payable conversion options, revenue recognition, the fair value of warrants, and the recognition and disclosure of contingent liabilities. Management evaluates its estimates on an ongoing basis. Actual results could materially vary from those estimates.
Cash and Restricted Cash	Cash and Restricted Cash The Company maintains cash balances that can, at times, exceed amounts insured by the Federal Deposit Insurance Corporation, which is up to $250,000. The Company has not experienced any losses in these accounts and believes it is not exposed to any significant credit risk in this area.
Concentrations of Credit Risk	Concentrations of Credit Risk At March 31, 2022 and December 31, 2021, the financial instruments which potentially expose the Company to concentration of credit risk consist of cash in financial institutions (in excess of federally insured limits) and trade receivables. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: For the three months ended March 31, 2022 and 2021, one customer accounted for 72.8%, and two customers in aggregate accounted for 49.9% of revenue, respectively. During the three months ended March 31, 2022 and 2021 , the Company's top five customers accounted for approximately 87.5% and 71.4%, respectively, o f the Company’s total revenue. At March 31, 2022 , two customers in aggregate accounted for 35.7% of accounts receivable. At December 31, 2021 , two customers in aggregate accounted for 32.2% of accounts receivable. Approximately 58.7% and 56.0% of the Company’s trade accounts receivable balance was with five customers at March 31, 2022 and December 31, 2021 , respectively. The Company estimates its maximum credit risk for accounts receivable at the amount recorded on the balance sheet. The trade accounts receivables are generally short-term and all probable bad debt losses have been appropriately considered in establishing the allowance for doubtful accounts.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs consist of direct and incremental costs incurred and fees paid for a commitment to obtain financing. As the commitment amount is funded, the carrying amount of the deferred financing costs is reduced and the amount is charged to additional-paid-in-capital. The deferred financing cost will be impaired if it becomes probable that funding of the commitment amount will not occur.
Recently adopted accounting pronouncements	Recently adopted accounting pronouncements None.
Recently issued accounting pronouncements not yet adopted	Recently issued accounting pronouncements not yet adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires, among other things, the use of a new current expected credit loss ("CECL") model in determining the allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable, and notes receivable. The CECL model requires that an entity estimate its lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. Entities will also be required to disclose information about how the entity developed the allowances, including changes in the factors that influenced its estimate of expected credit losses and the reasons for those changes. This update is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements.

(2) No cash dividends have been declared on the Company’s common stock since the Company’s inception, and the Company currently does not anticipate declaring or paying cash dividends over the expected life of the options. (3) The risk-free interest rate is based on the yields on U.S. Treasury debt securities with maturities approximating the estimated life of the options. (4) Volatility is estimated by management. As the Company has been a private company for most of its existence, there is not enough historical volatility data related to the Company’s Common stock as a public entity. Therefore, this estimate is based on the average volatility of certain public company peers within the Company’s industry.
