Danny Richter

Acting Director

Danny earned his Ph.D. in Oceanography from the Scripps Institution of Oceanography at UCSD. His research into global nutrient cycles gave his climate advocacy work solid grounding in the sciences. He spent 5 years as a volunteer for Citizens’ Climate Lobby (CCL), and upon completion of his studies spent 9 years leading CCL’s research and policy agendas. As Vice President of Government Affairs for CCL, Danny helped the organization grow to over 200,000 supporters, pass several pieces of legislation through Congress, and pioneered creative and conventional approaches to making climate an issue that both Democrats and Republicans were interested in solving. Of particular note was his role as the content and policy expert working with legislators in advance of the 2018 introduction of the Energy Innovation and Carbon Dividend Act. This piece of legislation was introduced with original co-sponsors from both parties in both the House and the Senate, making it the first bipartisan carbon price to be introduced in either chamber in 9 years, and the first such legislation introduced in both chambers.
