CRANE Tier
Investor-grade climate data.
Free. Permanently.
The CRANE Tier brings CRANE's open-access mission into Koi: the same methodology trusted by 6,000+ users and backed by Prime Coalition, now with AI-accelerated modeling and a continuously expanding data library.
Background
What is CRANE?
CRANE is a free, open-access framework for assessing the forward-looking GHG reduction potential of early-stage climate technologies. Created by Prime Coalition, Rho Impact, Greenometry, and Evergreen Climate Innovations, with the generous support of the MacArthur Foundation, NYSERDA, and the Massachusetts Clean Energy Center. CRANE has been the standard for climate investors since 2020.
The CRANE Tier on Koi preserves everything that made CRANE essential: open access, transparent methodology aligned with Project Frame, and no cost barrier. It adds Koi's AI-accelerated engine, a validated data lake of 10,000+ solution models, and modern collaboration tools.
