Nancy Pelosi, in her role as House Minority Leader, called for the Select Committee a week prior to the 2018 House elections,[7] telling TheNew York Times she wanted it to "prepare the way with evidence" for legislation to mitigate climate change.[8] In November and December 2018, youth climate activists with the Sunrise Movement pushed House Democrats to form a select committee with the mandate to draft "Green New Deal" legislation, working with incoming freshman Rep. Alexandria Ocasio-Cortez, who proposed language for the committee's authorization.[9] The activists staged a series of sit-ins in the offices of Nancy Pelosi, Steny Hoyer, and Jim McGovern, the incoming Speaker, Majority Leader, and Rules Committee chair. About two dozen Democratic members of Congress supported their proposal, but the incoming chairs of the Energy & Commerce and Natural Resources Committees, Reps. Frank Pallone and Raúl Grijalva, opposed it.[10][11]
The committee held its first field hearing on August 1, 2019, at the University of Colorado Boulder. The witnesses started with Colorado governor Jared Polis, followed by a panel that included the mayors of Boulder and Fort Collins, an expert in rural agricultural energy issues from Colorado State University, a representative of the oil and gas industry, and the director of the university's chief sustainability officer.
Following the November 2022 elections, the Republican Party obtained a majority in the House of Representatives. Garret Graves, the committee's ranking Republican, expressed an intent to end the committee.[12] On December 14, 2022, the committee released its final report.[13] The committee ceased to exist at the beginning of the 118th Congress on January 3, 2023.
