We’ll have to wait a bit for the Senate’s new committee chairs to be officially confirmed. But Jeff Navin, co-founder at the climate change-focused government affairs firm Boundary Stone Partners, told me that since selections are usually based on seniority, in many cases it’s already clear which Republicans are poised to lead under Trump and which Democrats will assume second-in-command (known as the ranking member). Here’s what we know so far.
1. Senate Committee on Energy and Natural Resources
This committee has been famously led by Joe Manchin, the former Democrat, now Independent senator from West Virginia, who will retire at the end of this legislative session. Energy and Natural Resources has a history of bipartisan collaboration and was integral in developing many of the key provisions in the Inflation Reduction Act —- and could thus play a key role in dismantling them. Overall, the committee oversees the DOE, the Department of the Interior, the U.S. Forest Service, and the Federal Energy Regulatory Commission, so it’s no small deal that its next chairman will likely be Mike Lee, the ultra-conservative Republican from Utah. That’s assuming that the committee's current ranking member, John Barrasso of Wyoming, wins his bid for Republican Senate whip, which seems very likely.
Lee opposes federal ownership of public lands, setting himself up to butt heads with Martin Heinrich, the Democrat from New Mexico and likely the committee’s next ranking member. Lee has also said that solving climate change is simply a matter of having more babies, as “problems of human imagination are not solved by more laws, they’re solved by more humans.” As Navin told me, “We've had this kind of safe space where so-called quiet climate policy could get done in the margins. And it’s not clear that that's going to continue to exist with the new leadership.”
2. Senate Environment and Public Works Committee
This committee is currently chaired by Democrat Tom Carper of Delaware, who is retiring after this term. Poised to take over is the Republican’s current ranking member, Shelley Moore Capito of West Virginia. She’s been a strong advocate for continued reliance on coal and natural gas power plants, while also carving out areas of bipartisan consensus on issues such as nuclear energy, carbon capture, and infrastructure projects during her tenure on the committee. The job of the Environment and Public Works committee is in the name: It oversees the EPA, writes key pieces of environmental legislation such as the Clean Air Act and Clean Water Act, and supervises public infrastructure projects such as highways, bridges, and dams.
Navin told me that many believe the new Democratic ranking member will be Sheldon Whitehouse of Rhode Island, although to do so, he would have to step down from his perch at the Senate Budget Committee, where he is currently chair. A tireless advocate of the climate cause, Whitehouse has worked on the Environment and Public Works committee for over 15 years, and lately seems to have had a relatively productive working relationship with Capito.
3. Senate Appropriations Subcommittee on Energy and Water Development
This subcommittee falls under the broader Senate Appropriations Committee and is responsible for allocating funding for the DOE, various water development projects, and various other agencies such as the Nuclear Regulatory Commission.
California’s Dianne Feinstein used to chair this subcommittee until her death last year, when Democrat Patty Murray of Washington took over. Navin told me that the subcommittee’s next leader will depend on how the game of “musical chairs” in the larger Appropriations Committee shakes out. Depending on their subcommittee preferences, the chair could end up being John Kennedy of Louisiana, outgoing Senate Minority Leader Mitch McConnell of Kentucky, or Lisa Murkowski of Alaska. It’s likewise hard to say who the top Democrat will be.
