Protecting the Climate



We use widely adopted standards to track our greenhouse gas emissions and our efforts to reduce them. In 2020:

Scope 1 direct emissions from combustible sources and refrigerants used in Home Depot operations totaled approximately 607,000 metric tons.

Scope 2 indirect emissions from purchasing electricity for our operations totaled approximately 1,214,000 metric tons.

• Scope 3 emissions from upstream transportation and distribution of freight for our operations totaled approximately 2,916,000 metric tons.

We reduced Scope 1 and 2 emissions by over 127,000 metric tons in 2020, achieving a 22% year-over-year reduction in carbon dioxide emitted per dollar of revenue earned.

Under our science-based target goal linked to our annual CDP reporting, we have committed to reducing our Scope 1 and Scope 2 carbon dioxide emissions 2.1% per year to achieve a 40% reduction by 2030 and a 50% reduction by 2035.

+DID YOU KNOW: We’ve committed to setting Science Based Targets initiative (SBTi) Scope 1, 2 and 3 goals by 2023 to reduce emissions in line with Paris Agreement goals.


Using resources wisely is a smart business strategy that also makes our store operations more sustainable. A few years ago we set a goal to reduce store kilowatt-hour electricity use 20% by 2020. We far surpassed our goal, cutting electricity use 44% between 2010 and 2020.

Conserving Electricity
A big driver of our store electricity efficiency is LED lighting; we’re on track to install LEDs in all of our U.S. stores by the end of fiscal 2021. Upgraded stores see electricity consumption drop by about 30%, on average, compared to using conventional lighting. Plus, the stores benefit from brighter aisles and better control over their technology-enhanced lights.

In addition, building automation systems installed in all U.S. and Canadian stores monitor conditions, such as indoor temperature and exterior light levels, reducing electricity consumption and maintenance costs. And we upgrade for efficiency. In 2020, we installed 836 energy-efficient heating, air-conditioning and ventilation systems in more than 70 U.S. stores.

+DID YOU KNOW: The Home Depot’s U.S. stores reduced electricity more than 14% year over year in 2020.

Using More Renewable Energy
Our company has pledged to have 100% renewable electricity for all Home Depot facilities worldwide by 2030. It’s an expansion of our previous commitment to buy or produce 335 megawatts of renewable or alternative energy by 2025. Harnessing power from the sun is crucial. We anticipate about three-quarters of our alternative and renewable energy capacity will come from solar by the end of 2023.

+DID YOU KNOW: We boosted our alternative and renewable energy capacity more than 13% in 2020, compared to 2019.


By making our supply chain more efficient, we reduce business costs and the impact that our product distribution has on the environment. We’ve made significant progress on our One Supply Chain plan, announced in 2017, to invest $1.2 billion to fund about 150 new supply chain facilities nationwide.

By the end of 2020, we had added over 30 distribution centers, increasing speed to final destinations and reducing miles traveled for goods processed through these facilities. Here are some of the ways we’re making our supply chain greener:

• Hydrogen fuel cells provide emissions-free fuel for forklifts at our supply chain facilities. We estimate that fuel cells in place in 12 locations in 2020 helped us reduce electricity consumption by about 16 million kilowatt hours.

• We sell available space on our trucks and buy space from other companies, ensuring fewer underloaded trailers hit the road. That space sharing saves about 2 million driven miles a year.

• By partnering with suppliers to forgo pallets, we can stack products to the top of trailers, resulting in as much as a 40% reduction in truck space needed to transport some goods.

• On the West Coast, one of our key transportation providers uses electric 18-wheelers, which have a 250-mile range and can be recharged to 80% capacity in 90 minutes.
