Her resolution, if successful, would overturn EPA’s “endangerment finding” that greenhouse gases threaten human welfare. The finding is a legal precursor to planned regulations that Murkowski opposes.
Sen. Mary Landrieu (D-La.) told reporters Wednesday that she’s working with Murkowski on proposals to prevent EPA from regulating the heat-trapping emissions under its current Clean Air Act powers.
Murkowski's efforts face major hurdles to clearing Congress and becoming law, but could provide a political signal about support for EPA rules if they garner significant Democratic support.
Obama administration officials say they want Congress to pass an emissions-cutting law but are prepared to proceed with EPA rules if Congress does not act.
Murkowski is vice-chair of the Senate Republican Conference and is also the ranking member of the Senate Energy and Natural Resources Committee.
