Walmart's climate commitments include a target to achieve zero emissions across its global operations by 2040. The company has near-term Science Based Targets initiative (SBTi) approved targets to reduce absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 35% by 2025 and 65% by 2030, both from a 2015 base year. Additionally, Walmart aims to reduce CO2e emissions from upstream and downstream Scope 3 sources by one billion tonnes between 2015 and 2030. Another SBTi target for Walmart Inc. sets a 27.84% reduction in absolute Scope 1 and 2 GHG emissions by FY2031 from a FY2025 base year, alongside working to reduce Scope 3 emissions by one billion tonnes by FY2031 from a FY2016 base year.

In 2025, Walmart's Scope 2 emissions (location-based) were approximately 9,670,000,000 kg CO2e. For 2024, the company reported Scope 1 emissions of approximately 9,030,000,000 kg CO2e, Scope 2 emissions (market-based) of about 6,610,000,000 kg CO2e, and Scope 3 emissions totalling approximately 636,570,000,000 kg CO2e. In 2023, Scope 1 emissions were around 8,930,000,000 kg CO2e, Scope 2 emissions (market-based) were about 6,540,000,000 kg CO2e, and Scope 3 emissions were approximately 625,300,000,000 kg CO2e. In 2022, Walmart's Scope 1 emissions were approximately 8,530,000,000 kg CO2e, Scope 2 emissions (market-based) were about 6,690,000,000 kg CO2e, and Scope 3 emissions stood at roughly 609,820,000,000 kg CO2e. The combined Scope 1 and 2 emissions saw a decrease of 23.2% between 2015 and 2021.
