California to Adopt First Locomotive Emissions Regulations

California regulators plan to vote on a proposed rule requiring train companies to transition to cleaner diesel and zero-emission locomotives to curb diesel pollution.
The rule would mandate the use of zero-emissions technology for certain locomotives beginning in 2030 and all freight locomotives in 2035.
The regulations aim to cut greenhouse gas emissions from locomotives by 21 million metric tons and reduce health impacts like premature deaths and hospital visits.
Diesel emissions from locomotives account for 70% of Californians' cancer risk from toxic air pollution.
If adopted, the rule would be the first of its kind in the U.S. and the most ambitious regulation on locomotive emissions.
