One of the Senate’s top Democrats is keeping focused on legislation to impose a carbon price, even as President Biden and many other Democratic lawmakers are coalescing around a clean electricity standard as their preferred climate policy.

Sen. Dick Durbin of Illinois, the second-highest-ranking Democrat in the chamber, unveiled legislation March 10 that would set a $25 per ton fee on carbon emissions beginning in 2023 that would increase $10 each year. The fee would apply first to emissions from fossil fuel production, expanding to cover nonfossil fuel high-emitting entities in 2025, according to a summary of the bill.
