ISO is developing its first net zero international standard.

The aim is to provide clarity, robust requirements, and enable comprehensive climate action for a sustainable world.

Expected to launch at COP30 in November 2025, the new standard is being designed to provide a global solution to guide organizations as they embark on their net zero transition.

It is an evolution of the ISO Net Zero Guidelines, which aimed to provide credible best practice and protect against greenwashing.

Meanwhile, thousands of experts across more than 170 countries are expected to collaborate through national standards bodies. A public consultation is expected to open later in 2025 to support global input.

“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,” said Noelia Garcia Nebra, Head, Sustainability, ISO.
