Placer Group is one of eleven groups in the Mother Lode Chapter of the Sierra Club.

We represent members in Placer County who reside west of the crest of the Sierra Nevada.

The Sierra Club was founded by John Muir, in California in 1892.  The stated goals were to explore, enjoy, and render accessible the mountain regions of the Pacific Coast; to publish authentic information concerning them; and to enlist the support and cooperation of the people and government in preserving the forest and other natural resources of the Sierra Nevada Mountains. Today we are energized by our Historical Accomplishments and prospective conservation objectives.

Happy to share this recent environmental achievement!

On March 29, 2024, the U.S. Environmental Protection Agency (EPA) announced a final rule, “Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles – Phase 3,” that sets stronger standards to reduce greenhouse gas emissions from heavy-duty (HD) vehicles beginning in model year (MY) 2027. The new standards will be applicable to HD vocational vehicles (such as delivery trucks, refuse haulers, public utility trucks, transit, shuttle, school buses, etc.) and tractors (such as day cabs and sleeper cabs on tractor-trailer trucks). The final “Phase 3” standards build on EPA’s Heavy-Duty Phase 2 program from 2016 and maintain that program’s flexible structure, which is designed to reflect the diverse nature of the heavy-duty vehicle industry. The standards are technology-neutral and performance-based, allowing each manufacturer to choose what set of emissions control technologies is best suited for them and the needs of their customers.
