Climate change is one of the greatest challenges of our time. If we don’t take more aggressive action now, the damage will only worsen, and the consequences will be disastrous for this and future generations.
As a retailer with operations in more than two dozen countries and sourcing that spans the globe, Walmart is deeply committed to addressing climate change. We’re focused on strengthening business resilience, advocating for climate action and targeting zero emissions across our global operations by 2040, without relying on carbon offsets.
In 2016, Walmart was also the first retailer with a science-based target designed to achieve emissions reduction in our own operations and supply chain, which we recently upgraded to align with the highest ambition of the Science-Based Target initiative. In 2020, we raised our aspiration to reduce emissions in our operations (scopes 1 & 2) by realigning our science-based target to a 1.5-degree Celsius trajectory, the highest ambition approved by the Science-Based Target initiative.
Because most emissions in the retail sector lie in product supply chains rather than in stores and distribution centers, we’re also working with suppliers through our Project Gigaton initiative to avoid a gigaton of greenhouse gas emissions from the global value chain by 2030. That’s the equivalent of taking over 200 million passenger vehicles off U.S. roads for a year.
More than 3,100 suppliers have signed on. Since the effort launched in 2017, suppliers report a total of 416 million metric tons of emissions avoided through energy, waste, packaging, agriculture, forests and product use and design.
In 2020, we raised our aspiration to reduce emissions in our operations (scopes 1 & 2) by realigning our science-based target to a 1.5-degree Celsius trajectory, the highest ambition approved by the SBTi. Our goal is to achieve zero emissions across Walmart’s global operations by 2040, reducing absolute scopes 1 and 2 GHG emissions by 35% by 2025 and by 65% by 2030 from our 2015 base year. We were the first U.S. retailer to make a zero emissions commitment that does not rely on carbon offsets.
We achieved a 12.1% reduction in scopes 1 and 2 emissions between our 2015 calendar year baseline and 2019.
In 2020, an estimated 36% of our electricity needs globally were supplied by renewable sources. Through systems installed at our facilities and through purchases from external providers, we aim to harvest enough wind, solar and other energy sources to power our facilities with 100% renewable energy by 2035.
We have more than 550 onsite and offsite projects and utility programs and partnerships in operation or under development in eight countries, 30 U.S. states and Puerto Rico.
According to solar and wind associations, in 2019, Walmart added more solar energy than any other company increasing our solar use by more than 35% and Walmart purchased the most wind energy of any company, signing contracts for over 500 megawatts.
