Assessment
What the evidence currently supports
EPA's February final rule rescinded the 2009 greenhouse-gas endangerment finding and federal greenhouse-gas standards for highway vehicles and engines. EPA says covered manufacturers no longer face future federal GHG measurement, control or reporting obligations under those rules. The action is effective but under review in the D.C. Circuit after challenges from governments and civil-society organizations.
EPA's own estimate; it is not an independently verified realized saving.
AP counted 24 states, 10 cities and five counties in the March 19 petition.
Change log
What changed
- EPA withdrew the 2009 finding that had provided the Clean Air Act predicate for federal vehicle greenhouse-gas regulation.
- Covered highway-engine and vehicle manufacturers no longer have future obligations under the rescinded federal GHG measurement, control and reporting rules.
- State and local governments joined environmental and public-health organizations in seeking judicial review.
Open questions
What remains uncertain
- The D.C. Circuit may uphold, narrow, stay or vacate the rescission.
- EPA's projected savings and competing estimates of emissions and health effects are disputed modeling outputs, not observed results.
- State standards, market changes and later federal action could alter the practical emissions effect.
