The Rio Grande Chapter of the Sierra Club is a volunteer-led organization representing more than 7,000 members and 10,000 supporters in New Mexico and West Texas. Our mission to is to explore, enjoy and protect the planet, and we prioritize action on protecting our climate, clean air, clean water, and conservation of wildlife and public lands in New Mexico and West Texas.

The Rio Grande Chapter was founded in 1963 and originally included New Mexico and all of Texas. In 1965, the Lone Star Chapter was formed. Lone Star encompasses all of Texas except for El Paso, Hudspeth and Culberson counties, which stayed with Rio Grande to this day.

Four regional groups make up the chapter:

  • Northern New Mexico Group
  • Central New Mexico Group
  • Southern New Mexico Group
  • El Paso Group

Each group has at least one representative on the chapter Executive Committee, which is made up of volunteers elected by members. To see the makeup of the Executive Committee or to contact a chapter leader, please click here.

The Executive Committee meets in person three times yearly to set priorities, vote on political endorsements and make decisions on budget and hiring of staff. The chapter currently employs four full­-time employees and one part-­time employee.
