Today we submitted our public comment on critical flaws in EPA's rationale for rescinding its authority to regulate greenhouse gas emissions. This proposed move is a big deal with profound implications for our future. Today's the last day to comment. www.cmu.edu/cit/veg/publ...
Transportation + electricity = most U.S. emissions. EVs can cut both—if we don’t slam the brakes on investments.

Trump reversed policies supporting electric vehicles − it will affect the road to clean electricity, too
An analysis finds that fewer electric vehicles will also mean less investment to clean up the electricity sector.

Trump signs exec order on 1st day back to “eliminate the EV mandate”. There was no national EV mandate, but changes to EPA standards and a successful revocation of California’s waiver to set its own policy would have big effects for the country’s top GHG-emitting sector. I discuss w/ PolitiFact:

Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.
The EPA granted California and 11 other states permission to ban the sale of new gasoline-powered cars by 2035. President-elect Donald Trump is expected to revoke the program, part of his pledge to scrap Biden-era climate policies.

New CMU/ANL study on incorporating energy justice and equity objectives in power system models takes a broad look at practices and opportunities across the literature

New paper alert: Climate Policy Reduces Racial Disparities in Air Pollution from Transportation and Power Generation (pubs.acs.org/doi/10.1021/...) #energysky #climatesky
Climate Policy Reduces Racial Disparities in Air Pollution from Transportation and Power Generation
Energy system optimization models facilitate analyses on a national or regional scale. However, understanding the impacts of climate policy on specific populations requires a much higher spatial resolution. Here, we link an energy system optimization model to an integrated assessment model via an emission downscaling algorithm, translating air pollution emissions from nine U.S. regions to U.S. counties. We simulate the impacts of six distinct policy scenarios, including a current policy and a 2050 net-zero target, on NOx, SO2, and PM2.5 emissions from on-road transportation and electricity generation. We compare different policies based on their ability to reduce emission exposure and exposure disparity across racial groups, allowing decision-makers to assess the air pollution impacts of various policy instruments more holistically. Modeled policies include a clean electricity standard, an on-road ICE vehicle ban, a carbon tax, and a scenario that reaches net-zero GHG emissions by 2050. While exposure and disparities decrease in all scenarios, our results reveal persistent disparities until at least 2040, particularly for Black non-Hispanic Americans. Our estimates of avoided deaths due to air pollution emphasize the importance of policy timing, showing that thousands of lives can be saved by taking action in the near-term.
