substack.comEPA argues its job is to do absolutely nothing about carbon emissionsThe agency charged with protecting public health and the environment is manufacturing new arguments claiming its job is to do nothing about climate pollutants under the Clean Air Act.

My Substack post on EPA's recent proposal to rescind all CO2 emission standards from power plants because it claims that it -suddenly - has no authority to do so under the Clean Air Act. EPA's comment period is open until Nov. 2. substack.com/home/post/p-...

Surreal experience as someone who worked on EPA's original GHG endangerment finding. My main message today: EPA is taking the extreme position that the only way it can be consistent with congressional intent and Supreme Court decisions is to do *nothing* to curtail emissions of GHGs

environmentalprotectionnetwork.orgEPN and L4GG Comments on Regulation for Federal Financial AssistanceOn July 13, 2026, Environmental Protection Network and Lawyers for Good Government submitted formal comments opposing the Office of Management and Budget’s proposed regulation governing federal financ...

The proposed OMB rule Regulation for Federal Financial Assistance is getting the attention it deserves. Thousands of comments were submitted by yesterday's deadline. The Environmental Protection Network submitted a comprehensive set of comments for anyone interested in a critique of OMB's proposal.

View full thread

** OMB has not fully considered the economic impacts of the proposal. ** The proposal purports to “restore gold standard science” and promote scientific integrity, including transparency and independent (unbiased) peer review. However, it is difficult to see how it would achieve these objectives.

The proposal would focus political oversight on review of individual research proposals, consuming time that would better be used for high-level leadership. It assumes that political judgement can legitimately supersede objective assessment of merit by multidisciplinary expert peer review.

View full thread

Moreover, this is the very first time that OMB is not providing direction in the form of guidance, but instead binding regulations.

Agencies cannot simply delegate to OMB their respective authority. These agencies have their respective statutory requirements to implement congressionally-mandated programs, some of which explicitly require scientific peer review to take precedence over political reviews.

www.environmentalprotectionnetwork.org/epn-and-l4gg...

OMB asserts they have the authority to promulgate this regulation by citing statutory language which states that the Deputy Director Manager is able to 'provide overall direction and leadership to the executive branch on financial management matters' but the proposal goes far beyond financial mgmt.

12 Feb

Today's EPA statement says that the endangerment finding was overreach by the Obama Admin. Actually, this process dates back to 1999 when EPA was petitioned to regulate GHGs under the Clean Air Act. That led to 2007 Mass v EPA Supreme Court decision which directed EPA to make a science-based finding

Barack Obama@barackobama.bsky.social

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate change—all so the fossil fuel industry can make even more money.

12 Feb

The Supreme Court, not the Obama EPA, ruled that GHGs are air pollutants under the Clean Air Act. The first draft tech support doc with all supporting science that eventually supported 2009 finding was released for public comment under the Bush Admin.

politico.comTrump EPA to take its biggest swing yet against climate change rulesWith its plans to revoke the endangerment finding, the administration is gambling that the Supreme Court will allow it to completely avoid regulating the nation’s top greenhouse gas sources.

11 Feb

Other arguments from last year's proposal seem to be at odds with the 2007 Mass v EPA Supreme Court decision, which held that GHGs meet the Clean Air Act's definition of an air pollutant and directed EPA to make a science-based decision whether GHGs cause endangerment

This EPA decided not to count benefits of pollution controls. No quantified accounting for avoided morbidity and mortality. This abandons decades of cost-benefit practice, economics and science. Claims that $ benefits estimates are too uncertain don't hold water theconversation.com/epas-new-way...
