Is Antitrust ESG's Achilles Heel ? House Republicans Think So.
December 13, 2022 | Blog | By Bruce Sokler, Jacob Hupart, Tinny Song, Payton Thornton
Prior to the recent midterm elections, we wrote about five Senate Republicans who issued a warning letter to major U.S. law firms regarding the potential antitrust implications of Environmental, Social, and Governance (“ESG”) investing and activities. The letter advises that ESG activities may be viewed as “climate cartels” and present antitrust risk when firms engage in ESG group initiatives. With the midterm election results, those Senate Republicans will likely not be able to follow through on this line of investigation. However, House Republicans have taken up the issue, and they will have the ability to conduct antitrust scrutiny of ESG initiatives.
