Walmart’s Greenhouse Gas Emissions

GHG Emissions in the Retail Sector

Greenhouse gas (GHG) emissions are one of the major causes of rising global warming. CO2, Methane & NOx gases form a major part of greenhouse gases released from fossil fuels such as oil and gas. Due to rising GHG emissions from the operations of companies, it became important among major contributing sectors to report GHG emissions during their operations.

Several retailers, including Walmart, already measure their carbon footprints and climate change programs. Retailers generate a significant portion of their carbon footprint in their stores. Heating, lighting, air conditioning, ventilation, cooking, and refrigeration are the main factors for direct energy consumption, and therefore carbon emissions, of a retail outlet.

GHG Emissions from Walmart

Walmart Inc (Walmart) is a retailer that operates grocery stores, supermarkets, hypermarkets, department and discount stores, and neighborhood markets. The company’s stores offer grocery and consumables, health and wellness, technology, office and entertainment, hardlines, apparel, and home categories at everyday low prices.

The total GHG emissions (Scope 1 and 2) of Walmart in 2020 were 16.43 million tonnes of CO2 equivalents (MtCO2eq), a decrease of 5% from 2019. Walmart has set a target to eliminate emissions in its global operations (scopes 1 and 2) by 2040 and aims to reduce one billion metric tons of GHGs in the global value chain (scope 3) by 2030.

GHG emissions are generally classified into Scope 1,2 & 3 emissions. Scope 1 includes direct GHG emissions from stationary fuel combustion and refrigerant gases. Scope 2 encompasses indirect GHG emissions from the on-site generation and purchase of electricity. Scope 3 involves all other indirect GHG emissions in the company’s value chain.

In 2020, Walmart’s Scope 1 emissions were 7.24 MtCO2eq, an increase of 6% over 2019, and Scope 2 emissions were 9.19 MtCO2eq, a decrease of 11% over 2019.
