In the first appellate decision to decide the issue since the Supreme Court decision in BP P.L.C. v. Mayor & City Council of Baltimore, the 10th Circuit ruled this week that climate damage claims brought by several Colorado counties should nonetheless still be heard in state court.  The most important issue in the case was whether the Clean Air “completely preempted” state law claims. … More

On Monday, Boston released a draft of the first phase of regulations intended to implement the amended BERDO ordinance signed by then-Mayor Janey in October. 

The first phase of the regulations is focused only on reporting issues.  It will address

• Reporting Requirements
• Third-Party Data Verification Requirements
• Preservation of Records

The rationale for this narrow focus is that the City wants these regulations in place promptly,… More

Earlier this week, Greenwire (subscription required) had an interesting story about the role that EPA’s estimate of the cost to comply with the Mercury and Air Toxics Standards rule played in the politics and judicial review of the rule.  It turned out that compliance costs were much less than originally estimated by EPA – let alone by industry.  Unfortunately, the $9.6 billion price tag originally put on the MATS rule lived on,… More

Last week, the Boston City Council approved amendments to the Building Energy Reporting and Disclosure Ordinance.  The changes are being referred to as “BERDO 2.0”, which almost understates the scope of the revisions.  As indicated by its name, since its original enactment, BERDO only dealt with reporting and disclosure.  Now, however, Boston will be imposing limits on GHG emissions from large buildings.

The limits will first be effective in 2025,… More

The IPCC has released its Sixth Assessment Report on the physical science basis of climate change.  I would say that it makes sobering reading, except any sane person’s immediate response to AR6 would be to go out and have any number of stiff drinks.  Here are a number of the lowlights:

It is unequivocal that human influence has warmed the atmosphere, ocean and land.… More

The biofuels industry has had a challenging season in the courts. Several weeks ago, the U.S. Supreme Court overturned a decision by the U.S. Court of Appeals for the Tenth Circuit that had limited EPA’s ability to grant waivers to small refiners that allow them to escape compliance obligations under the federal Renewable Fuel Standard (RFS) Program. Then, the U.S. Court of Appeals for the District of Columbia Circuit (the D.C.… More

In January, when Governor Baker vetoed the Legislature’s effort to go big on climate, my colleague Zach Gerson made clear that the bill was not even “mostly dead.”  I am pleased to say that Zach’s diagnosis was correct.  The climate bill is very much alive.

Last week, the Legislature passed a new version of the bill, which adopted most of the Governor’s technical suggestions and almost none of his substantive changes. … More

Within hours after being sworn into office, President Joe Biden signed an executive order (“EO”) that teed up a slew of clean air issues as top environmental priorities. The Biden administration signaled its plan to unwind four years of environmental and energy policies marked by aggressive deregulation and sidelining efforts to combat climate change.

Although only allotted a short paragraph in the EO,… More

There are few people left, at least in my orbit, who don’t share the goal of prompt decarbonization of the economy.  The quaintly named $64,000 question ($64 trillion question?) is how we get from here to there.

Today, the New England Power Generators Association released a report prepared by Analysis Group that explains how an economy-wide price on carbon can help New England do just that. … More
