The International Organization for Standardization (ISO) is developing its first international standard on net zero, aimed at providing clarity and robust requirements for the net zero transition. This standard will enable independently verified, comprehensive climate action and accelerate progress towards a sustainable world. It is expected to launch at COP30 in November 2025, offering a global solution to guide organisations on their net zero journeys.
Thousands of experts are expected to collaborate through national standards bodies across over 170 countries, and public consultation is expected to open later in 2025 to support global input.
The new standard is an evolution of the ISO Net Zero Guidelines, launched at COP27, into an independently verifiable international standard. The purpose of the Guidelines was to facilitate organisations to create comprehensive net zero strategies by providing them with credible best practices. The new standard will give the public greater confidence and guard against greenwashing by setting out robust guidance and requirements offering the potential to verify the credibility of claims.
“ISO takes our role in supporting a net zero transition seriously. As part of our Climate Commitment, we look forward to delivering an international standard the market has been asking for, and importantly, suitable for organisations of all sizes, sectors and geographies,” said Noelia Garcia Nebra, ISO Head of Sustainability.
