Should climate policy efforts in Congress continue to be pursued through bipartisan cooperation?
The Conservative Climate Caucus faces the potential loss of up to one-third of its 66 members following the November 2026 midterm elections. This anticipated turnover stems from a combination of retirements, primary losses, and highly competitive general election contests.
Why it matters
The shrinkage of this caucus could significantly reduce the pool of Republican legislative partners for climate policy. If Democrats gain control of the House as projected, the shift will likely alter the trajectory of environmental negotiations in Congress.
The caucus currently holds 66 seats in the U.S. House. With 15 members already confirmed as departing via retirement or primary loss and 11 members facing toss-up or unfavorable general election races, the group faces a projected reduction of approximately 33% of its total strength.
The players
Conservative Climate Caucus
A group of Republican members of the U.S. House focused on promoting market-oriented climate and environmental policy.
Mariannette Miller-Meeks
A Republican representative from Iowa currently facing a tight general election race leaning Democratic.
Jen Kiggans
A Republican representative from Virginia who is currently in a toss-up election race.
Juan Ciscomani
A Republican representative from Arizona currently engaged in a toss-up general election contest.
The details
The caucus acts as a forum for Republican members to discuss market-based climate solutions and environmental stewardship. Legislative shifts in this body are determined by internal primary outcomes and general election results across various districts. With 11 members currently locked in tight races—including those in Arizona, Virginia, and Iowa—the caucus must contend with a thinning bench of bipartisan-leaning representatives.
Timeline

The Tech Race
The potential decline in caucus membership follows a years-long period of muted climate rhetoric during the Donald Trump administration. This turnover risks leaving a vacuum in legislative climate efforts as the House moves toward a likely Democratic majority.
The makeup of the caucus affects which climate-related bills reach the House floor for debate. Voters in districts represented by members in toss-up races will directly determine the influence of moderate environmental voices in the next session.
The takeaway
The composition of the Conservative Climate Caucus will be finalized following the November 2026 elections. Observers should track the electoral outcomes of the 11 members in tight races to see how many climate-focused voices remain in the House.
