• ISO’s new standard will provide global guidance for net zero transitions.
• Thousands of experts from 170+ countries to collaborate.
• Public consultation to open in 2025 for global input.

ISO is developing its first international standard on net zero to provide clarity and robust requirements for the global net zero transition. Expected to launch at COP30 in November 2025, this standard will enable independently verified climate action, accelerating progress toward sustainability.

Noelia Garcia Nebra, ISO’s Head of Sustainability, announced the launch today at London Climate Action Week. “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 organizations of all sizes, sectors, and geographies,” she said.

Thousands of experts from over 170 countries will collaborate through national standards bodies, incorporating the latest climate science. A public consultation will open later in 2025 to ensure comprehensive global input.

This new standard evolves from the ISO Net Zero Guidelines introduced at COP27, which aimed to help organizations create credible net zero strategies. The forthcoming standard will offer robust guidance and requirements, enhancing public confidence and guarding against greenwashing by verifying the credibility of net zero claims.
