Northwest Cook County Group

Northwest Cook County Group of the Illinois Sierra Club

The NWCCG is an all-volunteer local group of the Illinois Chapter of the Sierra Club.  When you join Sierra Club you are automatically a member of the local group. The Sierra Club is America's oldest, largest and most influential grassroots environmental organization. We have approximately 2,000 members in the northwest suburbs of Cook County. The boundaries for our group include Arlington Heights, Barrington, Bartlett, Deer Park, Des Plaines, Elk Grove Village, Hoffman Estates, Mt Prospect, Palatine, Park Ridge, Rolling Meadows, Schaumburg, South Barrington, Streamwood and Wheeling. Please consider joining us on an outing or attending one of our programs or events to find out how you can become active about something you care about.

Tessine Murji is a conservation organizer with the Illinois Sierra Club based in Chicago. She manages the chapter's federal lobby team to make sure the Illinois delegation is consistently hearing from volunteers on Sierra Club priorities and that elected officials are living up to their endorsements. She also supports Chicago Group's City Climate Action Team where volunteers can lobby their respective aldermen on Sierra Club city-wide priorities. For our November Program, Tessine will discuss the environmental threat of Enbridge’s Line 5 pipeline, which transports 22 million gallons of crude oil and natural gas liquids across 645 miles of countryside every day. This aging oil pipeline violates tribal treaty rights and poses catastrophic risks to the drinking water for 40 million people and one-fifth of the world's surface freshwater. Governor Whitmer of Michigan ordered Enbridge to shut down Line 5 in May 2021. Yet, Enbridge continues to operate Line 5 illegally in spite of Governor Whitmer's shut down order.
