“We started Clearloop as total outsiders to the world of corporate sustainability, but with a deep passion to get in there, figure things out, and get things done. We’ve amassed some incredible support from academics, non-profits, companies, and just individuals who believe that we don’t have to sit around in despair–the beauty of climate action is that there’s room for bold, optimistic, and pragmatic solutions. Let’s dig in.”
We work with companies of all sizes to rethink their carbon footprint and expand access to clean energy.
