Colorado tops the country in EV sales for Q3, sets national state record - Aftermarket Matters Nearly 1 in 3 cars sold in the state were electric vehicles from July 1 to Sept. 30, 2025; Colorado has surpassed 210,000 EV registrations.

We saw a similar dynamic with EVs, where our ZEV standard in 2025 required that about 6% of sales be EV/PHEV, but our charging investments, purchase incentives and partnership with industry led to real world adoption over 25%. www.aftermarketmatters.com/regions/rock...

We have paired reasonable GHG regulations (designed to be workable so we don't export production and jobs to other states), with incentives like competitive decarbonization tax credits, and seen manufacturers reducing emissions way beyond the regulatory requirements. energyoffice.colorado.gov/citco

A Colorado clean air plan targeting dirtiest offenders is actually working. Here’s how. A Colorado air pollution plan to cut the biggest industrial emissions is working ahead of time, state records show.

"Efforts aimed at purifying the state’s worst industrial smokestacks has yielded stunning results — six years ahead of targets" - I am very proud of the state team from CDPHE and CO Energy Office that developed this program. (1/3)

E&E News: US insurance prices will rise if climate science center closes, actuaries warn An industry group told federal officials that losing the National Center for Atmospheric Research would weaken insurance “stability and affordability.”

The Trump administration's attack on atmospheric science has lots of collateral damage. Case in point- American Academy of Actuaries says shuttering NCAR will undermine the data insurers needed, likely leading to higher home insurance rates nationwide. subscriber.politicopro.com/article/eene...

As Trump Obliterates Climate Efforts, States Try to Fill the Gap

"The end of federal greenhouse gas limits is an obstacle, but not a death knell, in the fight against climate change on the state level, experts said.

Colorado helps explain why."

Trump administration orders aging Colorado coal plant to stay open, one day before closing The move continues the Trump administration’s support of coal, but drew a furious response from environmental groups and Colorado officials.

On a down note, the Trump administration ended the holiday season with a giant, expensive lump of coal in the stocking for ratepayers in CO –a ludicrous order to Tri-State to keep the unneeded, expensive, and currently broken Craig Unit 1 coal plant operational. (16/n)
