The International Organization for Standardization (ISO) announced that it has commenced work on the development of a new international standard on net zero, aimed at providing clarity and credibility to organizations’ net zero targets and strategies, and to guard against greenwashing.
The process to develop the standard follows the launch in 2022 at the COP27 climate conference of the ISO Net Zero Guidelines, providing a best-practices tool for organizations to use for the creation of comprehensive net zero strategies.
According to ISO, the new process will evolve the guidelines into an independently verifiable international net zero standard, which is expected to launch at the COP30 conference in November 2025.
The process to develop the new net zero standard is being convened by UK national standards body the British Standards Institution (BSI), in collaboration with Colombia’s national standards body ICONTEC, with expected participation of thousands of experts through national standards bodies across more than 170 countries, through national standards bodies across more than 170 countries, and a public consultation anticipated to open later in 2025.
The new process aims to address the complexity of the net zero landscape, with industries making progress on decarbonization, but while a “lack of clarity risks slowing down efforts to turn ambition into action.”
ISO Net Zero initiative
Thousands of specialists from over 170 countries are anticipated to collaborate through national standards bodies, integrating the latest advancements in climate science. A public consultation period will open later in 2025 to gather global feedback and ensure diverse perspectives are considered.
This standard evolves from the ISO Net Zero Guidelines introduced at COP27, transforming them into an internationally verifiable standard. The initial Guidelines aimed to help organizations develop detailed net zero strategies by providing reliable best practices. The new standard will enhance public trust and prevent greenwashing by establishing clear guidance and requirements, enabling verification of claims’ authenticity.
The British Standards Institution (BSI), representing the UK National Standards Body, is leading this initiative in collaboration with ICONTEC, Colombia’s National Standards Body. Experts who are interested in contributing to the development of the standard are welcome to join their National Standard Body’s climate change management committee by finding their country’s ISO member.
