Voluntary sustainability standards systems are market-based tools, designed to address the most pressing social and environmental challenges of our time.

These standards have a proven track record of delivering impacts at a global scale on the sustainability issues that matter most.

For more than 20 years, our members have developed rigorous but accessible sustainability standards across diverse sectors, providing a roadmap for sustainable development and a benchmark of quality.

We believe that standards systems that actively seek to integrate our Credibility Principles are more likely to be effecive tools for delivering positive sustainability impacts.
