In graduate school at Stanford, Dan sat in on a speech delivered by T.J.

Today, 3Degrees makes it possible for businesses to take urgent action on climate change by helping organizations around the world achieve renewable energy and decarbonization goals. Dan serves as Chairman of 3Degrees, focusing on the company’s long-term corporate strategy, strategic initiatives, and risk management.
