Financial Speculation in Capacity Markets Undermines the Energy Transition

Compounding their significant climate and environmental harms, fossil fuels are also volatile commodities. In 2022, Russia’s invasion of Ukraine disrupted the supply of natural gas, causing prices to spike. More recently, the United States’ war on Iran resulted in the closure of the Strait of Hormuz, one of the most […]

New Article Shows Climate-Alliance Emissions Reductions Are Not Antitrust Output Restrictions

Corporate coordination to mitigate climate change raises complex questions for competition policy. From a structural antitrust perspective, climate alliances comprised of large asset managers can raise the specter of unaccountable “private governance,” if effectively imposing clean-energy restraints across an entire sector. But from an econometric perspective, which seeks to optimize […]

AG Investigations and Copycat Anti-ESG Legislation Proliferate Despite Losses in Court

Last week, Texas v. BlackRock (E.D. Tex.), the first antitrust case challenging climate collaborations by financial institutions, reached an initial resolution. Texas Attorney General (“AG”) Ken Paxton announced that one of three institutional-investor defendants, Vanguard, had settled. As part of the settlement, Vanguard pledged not to “direct” its portfolio companies’ […]

Climate Skeptics Rush to Misuse Texas v. BlackRock

Texas v. BlackRock (E.D. Tex.) (BlackRock), a case in which 13 states claim that the institutional-investor defendants colluded to profit through coordinated output reductions at coal companies they partially owned, remains in its early stages, with discovery continuing through 2027. Already however, opponents of climate-risk mitigation have rushed to extract […]

State AG Attacks on Climate Alliances Still Lack Coherent Antitrust Theories

A now-familiar playbook for climate-denying state attorneys general is to launch burdensome investigations of climate-minded corporate enterprises based on inchoate antitrust claims (often conspicuously lacking a profit motive for the alleged antitrust violations). These enforcement tactics crystallize two challenges for corporate climate initiatives seeking to steer clear of antitrust liability. […]

The FTC Asserts (and Oversteps) its Antitrust Authority Against a Key Climate Alliance

Climate alliances have become a common target of antitrust campaigns over the last several years, particularly given the complex market dynamics for these alliances to navigate, with effective industry-wide transformation often necessitating some degree of coordination among competitors. In previous blog posts, we have addressed state legislatures’ efforts to undermine […]

Behavioral Effects of Corporate GHG Emissions Disclosures: A New Sabin Center White Paper

In recent years, roughly 30 nations have implemented regulatory regimes that mandate some type of greenhouse gas (GHG) emissions disclosure from corporations. As GHG emissions disclosure regimes continue to take hold, several key questions arise: will they prompt meaningful and sustained GHG emissions reductions, or will they merely serve to […]

State Anti-ESG Movement Evolves to Target Investor Access

With anti-ESG forces ascendant in national government, and federal agencies neglecting or outright reversing even modest regulatory efforts to address climate risks, fossil-fuel industry supporters have expanded their agenda at the state level. Through 100+ statehouse bills introduced this year, the anti-ESG agenda has moved beyond an initial targeting of […]
