Rep. Darrel Issa (R-CA-49) is the most recent Republican to join the bipartisan House Climate Solutions Caucus, which has blossomed to 26 total members. The Caucus was co-founded last year by Florida Reps. Carlos Curbelo and Ted Deutch.

In 2016, Issa said the U.S. needs “a plan for sustainable ecology.” He’s viewed the issue from a sustainability framework, noting “we have a carbon consumption problem and measuring how much and how long is one way to look at it from a climate change standpoint but it’s also a depleting resource… so yes, I want to make sure that we convert to sustainable energy. One of the challenges is, what’s the fastest way to get sustainable energy.”

At the time of posting, Issa had not issued a statement about his joining the climate group.
