Costco has some sustainability efforts and disclosures, but the level of progress or detail is below what we expect from a brand of its size. Its bulk goods / warehouse model helps it reduce packaging waste, but it still needs a lot of work to improve its emissions footprint.

Unlike many of its competitors, Costco does not contribute to climate-obstructive campaign financing, and is not a member of any climate-obstructive trade associations.

A large portion of the environmental impact of purchases made at retailers comes from upstream decisions on sourcing materials and ingredients. Retailers are responsible for these decisions for their whitelabel brands, but can also push change by highlighting sustainable options from other brands. Costco does not share targets to improve its sourcing for its whitelabel products. It also does not have any collections that are environmentally-mindful.

Costco does not offer in-store bags or boxes. Instead, it encourages customers to reuse boxes from upstream shipping, which helps reduce waste. It reports on its whitelabel packaging, and appears to use a minority of plastic, but it doesn’t share targets to further improve its materials.

Costco has initiatives to reduce food waste and waste from corporate operations, and it provides thorough reporting on its success rates.

Costco uses some (<50%) renewable energy in its supply chain, offices, and stores. Its reduction targets are not science-aligned, and are also far off track. Its emissions are significantly increased due to its gas station operations.
