History

The Conservative Climate Caucus was formed in 2021 by Representative John Curtis and a group of 52 Republican lawmakers concerned with the growing public and scientific consensus on the risks posed by climate change and the need for action. This included the acknowledgement of "decades of a global industrial era that has brought prosperity to the world has also contributed to that change.” The formation was a response to both environmental concerns and a recognition of the political imperative for conservatives to engage with the climate policy debate. Curtis left the House in preparation for the 2024 United States Senate election in Utah.
