A more sustainable future through information and innovation.

Since our earliest days, we’ve been on an ambitious journey to help build a more sustainable future.

Through our products, we aim to empower individuals, cities, and partners to collectively reduce 1 gigaton of their carbon equivalent emissions annually by 2030. For ourselves, we have a bold goal to reach net-zero emissions across all of our operations and value chain, which includes running on 24/7 carbon-free energy (CFE)8 on every grid where we operate.

A sustainable future requires systems-level change, strong government policies, and new technologies. We know that AI has the potential to help solve some of climate’s biggest challenges. Scaling AI and using it to accelerate climate action will be just as crucial as addressing the environmental impact associated with it.

We’re committed to collaboration and playing our part, every step of the way.

    1 Fuel-efficient routing was first launched in the U.S. in 2021. In 2023, we started rolling out fuel-efficient routing to India and Indonesia, adding to our existing coverage in the United States, Canada, Egypt, and nearly 40 European countries.

    2 Google uses an AI prediction model to estimate the expected fuel or energy consumption for each route option when users request driving directions. We identify the route that we predict will consume the least amount of fuel or energy. If this route is not already the fastest one and it offers meaningful energy and fuel savings with only a small increase in driving time, we recommend it to the user. To calculate enabled emissions reductions, we tally the fuel usage from the chosen fuel-efficient routes and subtract it from the predicted fuel consumption that would have occurred on the fastest route without fuel-efficient routing and apply adjustments for factors such as: CO2e factors, fleet mix factors, well-to-wheels factors, and powertrain mismatch factors. We then input the estimated prevented emissions into the EPA’s Greenhouse Gas Equivalencies Calculator to calculate equivalent cars off the road for a year. The cumulative figure covers estimated emissions prevented after fuel-efficient routing was launched, from October 2021 through December 2023, while the annual figure covers estimated emissions prevented from January 2023 through December 2023. Enabled emissions reductions estimates include inherent uncertainty due to factors that include the lack of primary data and precise information about real-world actions and their effects. These factors contribute to a range of possible outcomes, within which we report a central value.

    3 Our updated Fuel Cost Calculator, currently available in 21 countries, now includes results for both electric and fuel-based cars.
    4 Fuel-efficient routing in Google Maps is currently available in the United States, Canada, Egypt, and nearly 40 European countries.
    5 By the end of 2023, Google Maps contained approximately 400,000 EV charging locations globally.
    6 We now feature more climate-friendly transportation options in Search, showcasing long-distance train routes in 38 countries(1) and long-distance bus routes in 15 countries(2). (1) Train information on Search is available for travel in the following countries: Australia, Austria, Bangladesh, Belarus, Belgium, Canada, Croatia, Czechia, Denmark, Finland, France, Germany, Greece, Hungary, Indonesia, Ireland, Italy, Japan, Kazakhstan, Luxembourg, Malaysia, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Russia, Slovakia, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, Ukraine, United Kingdom, United States. (2) Bus information on Search is available for travel in the following countries: Brazil, Canada, Chile, France, Germany, Ireland, Italy, Japan, Mexico, Poland, Spain, Sweden, Ukraine, United Kingdom, United States.
    7 We aim to reduce 50% of our combined Scope 1, Scope 2 (market-based), and Scope 3 absolute emissions (compared to our 2019 base year) by 2030, and we plan to invest in nature-based and technology-based carbon removal solutions to neutralize our remaining emissions.
    8 We define freshwater as naturally occurring water from surface or groundwater sources that isn’t salty, and is suitable for consumption if clean or processed. Freshwater excludes seawater and reclaimed wastewater.
    9 Carbon-free energy is any type of electricity generation that doesn’t directly emit carbon dioxide, including (but not limited to) solar, wind, geothermal, hydropower, and nuclear. Sustainable biomass and carbon capture and storage (CCS) are special cases considered on a case-by-case basis, but are often also considered carbon-free energy sources.
