Our aim is that our business remains responsible, resilient and relevant in accordance with our Mission Statement and Code of Ethics.

To continually provide our members with quality goods and services at the lowest possible prices.

Sustainability to us is remaining a profitable business while doing the right thing. We have adopted the following principles and responsibilities to help us navigate the dynamic and changing future while still striving to do the right thing and remain a low-cost and efficient business operator.
Our Sustainability Principles
  • For Costco to thrive, the world needs to thrive. We are committed to doing our part to help.

  • We do not have all of the answers, are learning as we go and seek continuous improvement.
Our Sustainability Responsibilities

  • Support the communities where our employees and members live and work.
  • Operate efficiently and in an environmentally responsible manner.
  • Strategically source our merchandise in a sustainable manner.
In this document, we explain how we continue to incorporate sustainable practices in key aspects of our business. We provide examples to help illustrate our progress. We realize our practices may change over time, as we learn more and adapt to our ever-changing world, and we update our Commitment to reflect these changes.
