CTLCV Submits Public Comment in Support of Endangerment Finding

On Wednesday, August 20th, 2025, the Connecticut League of Conservation Voters participated in a press conference with Sen. Richard Blumenthal and the Department of Energy & Environmental Protection. 

Lori Brown, CTLCV Executive Director, at the event said, “The science is really clear. Greenhouse gas emissions make America sick, dirty and unstable. And from extreme weather and deadly flooding, to the increased smog along I-95, air pollution has a devastating effect on the quality of life for Connecticut residents. Eliminating the Endangerment Finding goes against overwhelming scientific consensus.” 

Below is CTLCV’s public comment submitted to the federal government in regards to the proposed rule by the Environmental Protection Agency on the Reconsideration of 2009 Endangerment Finding and Greenhouse Gas Vehicle Standard.

The public comment period will close on September 19th. Those interested in submitting public comments may do so at this link.

Public comment submitted by CTLCV: 

The Connecticut League of Conservation Voters (CTLCV) urges the EPA to
uphold the landmark 2009 Endangerment Finding and uphold our nation’s vehicle
pollution standards.

The science is clear: greenhouse gas emissions make America sick, dirty and
unstable. From extreme weather and deadly flooding in Connecticut, to increased
smog along I-95, air pollution has devastating effects on the quality of life for
Connecticut residents.

Eliminating the Endangerment Finding goes against overwhelming scientific
consensus and cedes U.S. leadership on climate change on the international stage.
The transportation sector is the largest source of greenhouse gas emissions in the
United States, and this is also true in Connecticut. This rule seeks to hide that
pollution so polluters can operate unchecked.

Connecticut has some of the worst air quality in the United States. Rolling
back this finding could worsen this, leading to an increase in the tens of millions of
dollars the state spends on healthcare every year. Additionally, in Connecticut’s
many coastal towns there will be a larger impact of sea level rise and severe
weather events.

The Endangerment Finding helps to lower greenhouse gas emissions and keep
our Connecticut communities safe. This means being able to breathe clean air for
picnics in the park, commutes to work and school, and strolls along Main Street.
To repeal it would endanger the health of Connecticut citizens and our quality of
life every single day.

The EPA must not abandon its core mission of protecting public health and the
environment. We urge the Environmental Protection Agency to NOT rescind the
landmark 2009 Endangerment Finding and to NOT roll back vehicle pollution
standards.
