How carbon standards are changing: inside the GHG Protocol and ISO merger

Summary On 29 July 2026, the Greenhouse Gas Protocol said it will merge its corporate standards (Scope 1, Scope 2, Scope 3 and market instruments) with the international standard ISO 14064-1 to make one global standard carrying both organisations’ names. The draft goes out for public comment in the second quarter of 2027. The GHG Protocol aims to publish the final standard at the end of 2028.
