Planet FWD is a San Francisco climate management platform that helps consumer brands measure, reduce and neutralize their carbon footprint. Founded in 2019 by Zume co-founder Julia Collins, the company pairs an AI-powered life-cycle assessment engine and a database built on 16+ years of research with Scope 1, 2 and 3 corporate inventories aligned to the GHG Protocol and the Science Based Targets initiative. The result: brands like Patagonia Provisions, Kashi, Just Salad and Numi Organic Tea can put an auditable carbon number on the products people actually buy - and get a roadmap to shrink it, on average by about 35% per product.
