Boston, November 14, 2022 – In response to a Green Century° shareholder proposal, Costco,* one of the largest retailers in the world, has committed to setting climate emissions reduction targets for its full value chain — cumulatively called “scope 3” emissions — in 2023. The commitment comes after 70% of its voting shareholders opted in January 2022 for a Green Century proposal asking Costco to include the emissions from its producers, shippers and other partners when setting targets to reach net zero emissions by 2050.

“With this commitment, Costco is no longer a laggard among its peers. So, we congratulate the company on committing to reduce its contribution to climate change,” said Green Century President Leslie Samuelrich. “Costco’s plan to set a scope 3 emissions reduction target in 2023 shows that the company is starting to treat climate change with the gravity that the issue – and shareholders – demand.”

Historically, Costco has significantly trailed many of its competitors on climate action, standing out as one of only three of the largest 50 S&P companies without a major climate commitment as of December 2021. At Costco’s January 2022 annual meeting, Green Century called on the company to set science-based emissions reduction targets for its scope 1, 2, and 3 emissions that would lead to achieving net zero emissions by 2050 or sooner. Scope 1 and 2 emissions are those from a company’s operations and purchased energy, while the emissions from its supply chains and the use of its products are known as scope 3.

In response, Costco committed to disclosing the company’s aggregate scope 3 emissions and action plan in 2022, and to set scope 3 reduction targets in 2023, which likely represents the vast majority of the company’s climate impact. (For context, Walmart* has estimated that for retailers, roughly 95% of emissions are in scope 3.) In addition, Costo committed to updating its scope 1 and 2 emissions targets and action plans as part of its revised Climate Action Plan coming out in December 2022.

“Costco has certainly accelerated its work on this issue and we are pleased that it is heeding the call from shareholders to address climate risk,” said Green Century’s Director of Shareholder Advocacy Annie Sanders. “That said, we are disappointed that the company has declined to pursue alignment of the company’s climate targets with the Science Based Targets initiative, the global body enabling businesses to set emissions reduction targets in line with science. We strongly urge Costco to join its peers in taking this crucial step to avoid the worst consequences of climate change and mitigate climate risk in line with investor expectations.”
