The House of Representatives on Wednesday passed a bill aiming to block the EPA from finalizing stricter emissions rules for model years 2027-2032. The bill, H.R. 4468, or the “Choice in Automobile Retail Sales Act of 2023,” seeks to prohibit the EPA from “finalizing, implementing, or enforcing a proposed rule with respect to emissions from

Stellantis is petitioning against strict emissions standards adopted by California and 13 other states, claiming they give other automakers competitive advantages. First reported by Bloomberg, the petition is based around a claim that the California Air Resources Board (CARB) “improperly adopted” a 2019 deal negotiated between the regulator and four automakers, in which those automakers
