The Sierra Club is the statewide voice for the nation's oldest, largest and most influential grassroots environmental organization. Sierra Club is 18,000 members strong in Michigan. We are volunteer-led and we actively coordinate our work on many levels. Sierra Club's ten groups in Michigan work for healthier communities at the local level. The Michigan Chapter works with volunteer leaders, state agencies and the legislature for better environmental stewardship statewide.
