Protecting the Climate


Our company tracks our carbon dioxide emissions from distribution, store energy use and more, using metrics that are industry standards:

Scope 1: Direct emissions from combustible sources and refrigerants

Scope 2: Indirect emissions from purchasing electricity

• Scope 3: Emissions from upstream transportation and distribution of freight

We reduced Scope 1 and Scope 2 emissions 10% and Scope 3 emissions 1% year over year in 2019, the most recent data available.

We assess progress using the GHG Protocol Corporate Accounting and Reporting Standard, which over 90% of Fortune 500 companies use to calculate metric tons of greenhouse gas emissions and efforts to reduce them. We also participate in the CDP® reporting process. CDP, formerly the Carbon Disclosure Project, is an independent, international, nonprofit organization that provides a global system for companies to measure, disclose, manage and share environmental information. The Home Depot received a score of A- from CDP for our latest report.

+DID YOU KNOW? The Home Depot has pledged to reduce CO2 emissions 2.1% per year to achieve a 40% reduction by 2030 and a 50% reduction by 2035.


The simplest way to reduce emissions from energy use is to use less energy, and The Home Depot has made significant progress. We reduced U.S. store electricity consumption by 383 million kilowatt hours in 2019, compared to a reduction of 98 million kilowatt hours in 2018. Our energy use decreased even as we added new stores to our footprint.

Electricity consumption by our U.S. stores dropped 35% between 2010 and 2019. We’re ahead of our stated 2020 goal to achieve a 20% reduction in store kilowatt-hour energy use, compared to 2010 consumption. In 2019 alone, U.S. store energy consumption dropped 12% year over year.

Our substantial energy-saving progress in recent years has been led by the ongoing installation of LED lighting across our U.S. stores. We also installed energy-efficient heating, air-conditioning and ventilation systems in more U.S. stores. We continue to benefit from previously installed building automation systems in all U.S. and Canadian stores. In addition, variable frequency drives in hundreds of our stores help ensure we’re using only the amount of electricity needed to meet immediate air-conditioning and heating demands.


The Home Depot has set a target to procure or produce 335 megawatts of renewable or alternative energy by 2025. We’re tapping into sustainable energy produced on-site and off-site:

• Soccer-field-size Home Depot store rooftops have become solar farms. At the end of 2019, 47 stores had rooftop solar, and projects were in development at another 45 stores.

• Fuel cells — mini power plants that can cut polluting emissions as much as 50% compared to traditional power sources — operate outside more than 200 of our U.S. stores.

• We purchase enough energy from a wind farm in Texas to power 105 stores.

• Our solar energy contracts in Delaware, Massachusetts and Minnesota boost the business case for sun-powered electricity in those areas.

By leveraging alternative and renewable energy sources, we reduce our carbon footprint and strengthen the viability of these innovations.
