Environmental data The following table provides an overview of our performance over time and includes both environmental data for our global operations (including our data centers, offices, networking infrastructure, and other facilities) and data beyond our operations (including our investments and technology). The majority of our environmental data covers Alphabet Inc. and its subsidiaries, including Google LLC. All reported data is global and annual unless otherwise specified. We obtain third-party assurance from an independent, accredited auditor for specific environmental data as part of our Independent Accountants’ Review, including select energy, emissions, and water metrics, indicated in the table below. For more information on our 2019 energy use and GHG emissions, see Alphabet’s 2020 CDP Climate Change Response.
