Two carbon pricing bills were introduced during the 115th Congress. Reps. Carlos Curbelo (R-Fla.) and Brian Fitzpatrick (R-Pa.) introduced the MARKET CHOICE Act during the summer of 2018. Reps. Ted Deutsch (D-Fla.) and Francis Rooney (R-Fla.) introduced the Energy Innovation and Carbon Dividend Act (Energy Innovation Act) in November 2018, and reintroduced it early in the 116th Congress, where it presently has more than 65 cosponsors. By different methods and with different comprehensiveness, both of these bills place a Pigouvian tax on greenhouse gas (GHG) emissions.

The U.S. Department of the Interior and National Oceanic and Atmospheric Administration recently finalized comprehensive changes in how the Endangered Species Act (ESA) is implemented. These changes address the species listing process, critical habitat designations, protections for threatened species, and the §7 consultation process.

Federal dams have been the focus of major disputes involving application of the Endangered Species Act (ESA), especially its §7 prohibitions on federal actions causing jeopardy to protected species. Operating agencies and project beneficiaries have sought to keep the ESA from restricting dam operations, including by arguing that such operations are non-discretionary and thus exempt. In proposing new ESA implementing rules, the Trump Administration suggested, but did not formally propose, that ongoing federal actions should be considered part of the “environmental baseline” for §7 purposes.
