TABLE OF CONTENTS

Whichever method you chose to vote, please carefully read this Proxy Statement, which describes in detail the proposal upon which you are asked to vote.
You will be entitled to cast one vote for each dollar and fraction of a dollar of net asset value of the Fund share class you hold (number of shares and fractions of shares owned multiplied by the net asset value per share). The votes of the shareholders of the Balanced Fund, the Equity Fund and the EquityInternational Fund will be tabulatedtogetherfor the proposal.
All properly executed proxies received prior to the Meeting will be voted at the Meeting. On the matters coming before the Meeting as to which a shareholder has specified a choice on that shareholder’s proxy, the shares will be voted accordingly.
Even if you plan to attend the Meeting, please sign, date and return EACH proxy card you receive. Alternatively, if you vote by telephone or over the Internet, you will be asked to enter a unique code that has been assigned to you, which is printed on your proxy card(s). This code is designed to confirm your identity, provide access into the voting sites and confirm that your instructions are properly recorded.
If you hold your shares directly (not through a broker-dealer, bank or other financial institution), and if you return a signed proxy card that does not specify how you wish to vote on Proposal 1, your shares will be voted in favor of all of the nominees.
Abstentions and “broker non-votes” (shares held by brokers or nominees, typically in “street name,” as to which proxies have been returned but (a) instructions have not been received from the beneficial owners or persons entitled to vote and (b) the broker or nominee does not have discretionary voting power on a particular matter) generally are included for purposes of determining whether a quorum is present at a shareholder meeting, but are not treated as votes cast at such meeting. However, because the Funds understand that a broker or nominee may exercise discretionary voting power with respect to Proposal 1, and there are no other proposals expected to come before the Meeting for which a broker or nominee would not have discretionary voting authority, the Funds do not anticipate that there will be any “broker non-votes” at the Meeting.
Broker-dealer firms holding shares of a Fund in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on the Proposal before the Meeting. A signed proxy card or other authorization by a beneficial owner of Fund shares that does not specify how the beneficial owner’s
3

TABLE OF CONTENTS

shares should be voted on Proposal 1 may be deemed an instruction to vote such shares in favor of all of the nominees. With respect to routine matters such as Proposal 1, if a beneficial owner fails to provide voting instructions by the date specified in a broker-dealer firm’s proxy solicitation materials, the Trust understands that the broker-dealer firm may exercise discretionary voting power with respect to Proposal 1 on behalf of such beneficial owner.
If you hold shares of a Fund through a bank or other financial institution or intermediary (called a service agent) that has entered into a service agreement with the Fund or a distributor of the Fund, the service agent may be the record holder of your shares. At the Meeting, a service agent will vote shares for which it receives instructions from its customers in accordance with those instructions. A signed proxy card or other authorization by a shareholder that does not specify how the shareholder’s shares should be voted on the Proposal may be deemed to authorize a service agent to vote such shares in favor of the nominees. Depending on its policies, applicable law or contractual or other restrictions, a service agent may be permitted to vote shares with respect to which it has not received specific voting instructions from its customers. In those cases, the service agent may, but may not be required to, vote such shares in the same proportion as those shares for which the service agent has received voting instructions.
If you beneficially own shares that are held in “street name” through a broker-dealer or that are held of record by a service agent and you do not give specific voting instructions for your shares, they may not be voted at all or, as described above, they may be voted in a manner that you may not intend. Therefore, you are strongly encouraged to give your broker-dealer or service agent specific instructions as to how you want your shares to be voted.
If you receive more than one proxy card, please vote each proxy card separately, either by returning each card via mail or by voting each card on the toll-free number or online. You may receive more than one proxy card if you hold shares in more than one account in the Funds and/or if you hold shares in more than one of the Green Century Funds. To vote all your shares and accounts, please vote each of the proxy cards you receive.

If you return your proxy and fail to provide instructions as to how to vote your shares with respect to the proposal, your shares will be voted FOR the proposal.

Record Date

The close of business on July 22, 2014 wasMarch 31, 2021was fixed as the Record Date for the determination of shareholders entitled to vote at the Meeting. 5,103,512.4398,798,752.131 shares of the Balanced Fund Individual Investor Share Class (par value $0.01 per share), 2,057,932.010 shares of the Balanced Fund Institutional Share, Class (par value $0.01 per share), 4,835,846.017 shares of the Equity Fund Individual Investor Share Class (par value $0.01 per share), 2,287,130.382 shares of the Equity Fund Institutional Share Class (par value $0.01 per share), 2,871,564.893 shares of the International Fund Individual Investor Share Class (par value $0.01 per share) and 3,138,277.3566,914,758.791 shares of the EquityInternational Fund Institutional Share Class (par value $0.01 per share) were outstanding as of the close of business on the Record Date.

Quorum

Holders of a majority of the voting power of the shares of each Fund outstandingentitled to vote on the Record Date constitute a quorum and must be present in person or represented by proxy at the Meeting for purposes of voting on the proposal. Your shares will be represented by proxy at the Meeting if you vote by mail, by telephone, or online.

Regardless of how you vote (“For”For All”, “Against”“Withhold All” or “Abstain”“For All Except”), your shares will be counted for purposes of determining the presence of a quorum. In addition, abstentions and broker “non-votes” (that is shares held by brokers or nominees as to which (a) instructions have not been received from the beneficial owner or other persons entitled to vote and (b) the broker or nominee does not have discretionary power to vote on a particular matter) will be countedgenerally are included for purposes of determining the presence of a quorum.

quorum at a shareholder meeting.

With respect to the election of Trustees, nominees must be elected by a plurality of the votes cast in person or by proxy at the meeting at which a quorum exists. Abstentions and broker “non-votes” are not considered “votes cast” and therefore, do not constitute a vote “For” the proposal. Thus, abstentions and broker “non-votes” will have no effect on the voting for the election of Trustees in the proposal because only “for” votes are considered in a plurality voting requirement.
As noted above because the Funds understand that a broker or nominee may exercise discretionary voting power with respect to Proposal 1, and there are no other proposals expected to come before the Meeting for which a broker or nominee would not have discretionary voting authority, the Funds do not anticipate that there will be any “broker non-votes” at the Meeting.

TABLE OF CONTENTS

Revoking Your Proxy

You may revoke your proxy at any time prior to the Meeting (or any adjournment or postponement thereof) by putting your revocation in writing, signing it and either delivering it to the Meeting or sending it to Amy F. Puffer, Secretary of the Green Century Funds, 114 State Street, Suite 200, Boston, MA 02109. If you hold shares through a bank or other intermediary, please consult your bank or intermediary regarding your ability to revoke voting instructions after such instructions have been provided. You may also revoke your proxy by voting in person at the Meeting.

Adjournments and Postponements

If sufficient votes in favor of the proposal are not received, the persons named as proxies may propose one or more adjournments of the Meeting to permit further solicitation of proxies with respect to the proposal. An adjournment or postponement of the Meeting will suspend the Meeting to another time. Any such adjournment will require the affirmative vote of a majority of those shares voted at the Meeting. If you voted in favor of the proposal or failed to provide instructions as to how to vote your shares with respect to the proposal (including broker non-votes), the persons named as proxies will vote your shares in favor of the adjournment of the Meeting with respect to the proposal. If you voted against or abstained from voting on the proposal, the persons named as proxies will vote your shares against any such adjournment.

Any proposal for which sufficient favorable votes have been received by the time of the Meeting may be acted upon and considered final regardless of whether the Meeting is adjourned to permit the additional solicitation of proxies with respect to another proposal. The Meeting may be postponed prior to the Meeting. If the Meeting is postponed, the Fund will give notice of the postponement to shareholders. If we decide to hold the Meeting at a different time or in a different location, we will announce any such updates by means of a press release, which will be posted on our website at www.greencentury.com. An announcement will also be filed with the Securities and Exchange Commission via its EDGAR system. In the event of any inconsistency between this proxy statement and the Funds’ governing documents or applicable law, the Funds’ governing documents and applicable law will control.

Proxy Solicitation Costs

The cost of soliciting proxies (which is expected to be approximately $25,000), including the fees of a proxy soliciting agent (which are expected to be approximately $20,000)$122,000), will be borne by Green Century Capital Management, not the Funds. Green Century Capital Management has entered into a contract with Broadridge Investor Communication Solutions, Inc. to provide proxy services which will include printing and distributing this Proxy Statement and proxy cards to the Funds’ shareholders, providing the means by

which shareholders may vote (mail, telephone, internet), tabulating the results of the votes and additional solicitation services.
In addition to solicitation by mail and the proxy soliciting agent, proxies may be solicited by the Board of Trustees, officers, and regular employees and agents of the Funds and Green Century without compensation.

The Trustees are experienced business people, attorneys and non-profit organization managers who meet periodically throughout the year to oversee the Funds’ activities, review contractual arrangements with companies that provide services to the Funds, oversee management of the risks associated with such activities and contractual arrangements, and review the Funds’ performance and expenses, among other reviews and assessments. In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the individual Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board, as a whole, to operate effectively in governing the Funds and protecting the interests of shareholders. In addition, each Trustee is committed to the Funds’ and Green Century’s mission of offering environmentally responsible and fossil fuel free mutual funds and advocating for greater corporate environmental accountability.

Trustee Oversight Responsibilities

The Chairperson of the Board of Trustees of the Funds is an Independent Trustee, as defined in the 1940 Act. HeThe Chairperson presides at meetings of the Board and at executive sessions of the Independent Trustees. The Independent Chairperson is appointed by a majority of the Independent Trustees. It is the policy of the Board that the Independent Chairperson of the Board, with full responsibilities as a chairperson would generally have, will continue to be an Independent Trustee. The Board of Trustees has determined that having its Chairperson be an Independent Trustee is in the best interests of the Funds’ shareholders.

The Board has fourfive standing committees, described in more detail below. Through the committees, particularly the Audit Committee, the Independent Trustees consider and address important matters involving the Funds, including those presenting conflicts or potential conflicts of interest with management. The Board has determined that delegation to the committees of specified oversight responsibilities helps ensure that the Funds have effective independent governance and oversight. The Board has determined that its leadership and committee structure is appropriate given Green Century’s role with respect to the Funds’ investment and business operations. The Board believes that the leadership and committee structure providesprovide effective management for the relationships between the Funds, Green Century and the Funds’ other principal service providers, and facilitates the exercise of the Board’s independent judgment in evaluating and managing the relationships.

Like other mutual funds, the Funds are subject to risks, including investment, compliance, operational and valuation risks, among others. The Board oversees risk as part of its oversight of the Funds. Risk oversight is addressed as part of various Board and committee activities. The Board, directly or through its committees, interacts with and reviews reports from, among others, the Funds’ investment adviser and administrator, Green Century, the Funds’ Chief Compliance Officer (CCO), the Funds’ investment subadvisers, and the Funds’ independent registered public accounting firm, as appropriate, regarding risks faced by the Funds and risk management.

The Board has designated the CCO to be responsible for the Funds’ compliance policies and procedures. The CCO reports to the Independent Trustees of the Board and is responsible for delivering, at least annually, a written report on compliance and other required or agreed on matters to the Board. The Independent Trustees of the Board also meet with the CCO, separately from management, generally at least annually, to address compliance issues and other relevant matters.

TABLE OF CONTENTS

The actual day-to-day risk management functions with respect to the Funds are subsumed within the responsibilities of the investment adviser and administrator, the subadvisers, and other service providers, depending upon the nature of the risk. In the course of its interactions with the various service providers, the Board has emphasized the importance of maintaining vigorous risk management programs and procedures. The Trustees recognize that not all risks that may affect the Funds can be identified. Processes and controls developed cannot eliminate or mitigate the occurrence or effects of all risks, and some risks may be simply beyond any processes, procedures or controls of the Board, the Funds, Green Century, or other service providers. As a result of the foregoing and for other reasons, the Board’s risk management oversight is subject to substantial limitations.
