The Climate Label
The Climate Label
The Climate Label certifies companies that measure and publicly disclose their greenhouse-gas emissions, set a financial commitment (a “climate transition budget”) tied to those emissions, and allocate verified funding for projects that reduce or remove emissions from their operations, supply-chain and beyond. Unlike a simple “carbon-neutral” claim, the label emphasises actual investment in the transition to a low-carbon future, not just offsets, and is designed to increase transparency and credibility for climate action by businesses.
