Costco Wholesale

In 2024, Costco Wholesale reported approximately 673 million kg CO2e in Scope 1 emissions, primarily from fugitive emissions. This marks an increase from 613.6 million kg CO2e in 2023. The company has not disclosed Scope 2 or Scope 3 emissions data for these years, indicating a lack of comprehensive reporting in these areas.

Costco's total emissions for 2021 were approximately 157.9 million kg CO2e, which included 1.2 billion kg CO2e from Scope 1, 1.4 billion kg CO2e from Scope 2, and about 155.3 billion kg CO2e from Scope 3 emissions. This data reflects a significant reliance on Scope 3 emissions, which encompass indirect emissions from the supply chain and product use.

Despite the increase in Scope 1 emissions, Costco has not set specific reduction targets or initiatives, as indicated by the absence of documented reduction targets or climate pledges. The company’s emissions data is self-reported and does not appear to be cascaded from any parent organisation.

Overall, while Costco has made strides in emissions reporting, the lack of comprehensive data and reduction commitments highlights an area for potential improvement in their climate strategy.
