With an easy donation or personal investment you can have a direct link to early stage companies at the forefront of the climate tech revolution, participating in their impact, job creation, technological innovation, and hopefully gains!


The Decarbon8-US Fund is a philanthropic impact fund that allows anyone to make a gift or grant, which is then invested in decarbonization startups selected by our judges.  Larger gifts or grants (>$5k) even qualify for recovering any returns into a philanthropic fund (or reinvesting them). E8 Members and other accredited investors may also personally co-invest in the winning, finalist investments. The three D8 investments from 2020 have seen revenue grow 300%+, with Xeal, Steelhead Composites and Earthly Labs all completing investment rounds since.


Our 2021 cycle focused on decarbonizing and transforming transportation. ​

Our Progress and Pathways


These strategies can get us to a clean energy future and we are thrilled that our first three investments are performing well. 

Xeal (EV charging software) has completed a new bridge round and has seen a spike in revenue and sales.  Steelhead Composite’s carbon wrapped pressure vessels are used in storing hydrogen for myriad uses, as well as aerospace and even scuba; they’re booming and completed their Series A. Earthly Lab’s small scale carbon capture is similarly accelerating, with record sales into their brewery and distillery markets; their Series A is almost complete. 

This is where we need to go—and how we can get there.
