The fashion industry is responsible for 5–10% of global greenhouse gas (GHG) emissions. As climate pressure grows, fashion companies need carbon tools built for their reality, not generic platforms.

Carbonfact is the Environmental Intelligence Platform for textile and fashion. We turn messy business data into environmental intelligence so brands can measure, model, reduce, and report on their impact with confidence.

We've raised $17M from top-tier investors including Alven, Headline, and Y Combinator, and we're trusted by brands like Carhartt, GANNI, On, Burton, Armedangels, Jack Wolfskin, and many more.
