Green Country Group

We are working urgently to protect northeastern Oklahoma from industrial poultry farms that pollute our air and water. Read more and watch a video here.

Sierra Club Green Country GroupWe are 1,500 members of the Sierra Club in the 28 counties of eastern Oklahoma. Our mission is to Explore, Enjoy and Protect the planet, through outings, activism, education, social events and volunteer activities. Green Country is part of the Sierra Club's Oklahoma Chapter.

If you have a home address in eastern Oklahoma and join the national Sierra Club, you will automatically become a member of the Green Country Group. 

Electric Vehicles are Leading the Future of Oklahomans!

This past year Green Country Sierra Club partnered with Clean Cities-INCOG program to host our first NDEW event. We had a wide array of new EV cars available for test drives and dealer representatives with the cars.  We also included many owner-owned EV cars.  There is no one more knowledgeable than an experienced electric vehicle owner.  The public gathered at Eastside Christian Church parking lot near 15th and Harvard to sit in, drive and have great conversations with the dealers and owners of EV's.  Electric vehicles are the transportation of the future including cars, mass transit, buses, school buses and all sizes of trucks up to semi-trailer trucks. Our world is changing for the better!

Oklahoma City and Tulsa regularly have an F rating on the Department of Environmental Quality annual air quality report.  Rural areas are much healthier with C and above ratings.  We cannot allow our dirty air to continue because it is harming the health of everyone, especially the very young and very old members of our community. We could reduce our carbon pollution in urban areas by 70% if all vehicular travel was electrically operated.  When you buy your next vehicle, please check out electric cars and trucks first.  No emissions travel is excellent for our community and our people.


All Green Country Group meetings and events are free and open to the public. Our monthly general meeting is held at 6:00 pm-social networking, 6:30 pm-work session, 7:00 pm-speaker on the last Thursday of each month at the Linnaeus Teaching Gardens, Helmerich Classroom in the red barn behind the Tulsa Garden Center at 2435 S.

Sierra Club Oklahoma Green Country

The Wind Coalition, the leading advocacy organization representing the wind energy industry in Oklahoma and throughout America’s Wind Corridor, announced the hiring of Mark Yates as Oklahoma Director. Yates will coordinate advocacy, education and community relations efforts across Oklahoma promoting the positive economic benefits that the wind industry is delivering to Oklahoma ratepayers and communities.

Yates said, “Oklahoma can power Oklahoma and I look forward to working with our community leaders and elected officials to build an Oklahoma that is energy independent. With our infinite wind energy and vast natural gas resources, we can end our dependence on imported fuels and deliver cleaner, cheaper electric power to Oklahoma citizens. Wind energy continues to grow in Oklahoma because it provides opportunity in so many ways. For farmers and ranchers, wind provides an opportunity at reliable income from their land. For communities and schools, wind provides needed funding. For every Oklahoma consumer, wind provides cleaner, cheaper ‘Made in Oklahoma’ energy. The future is bright and I am proud to be a part of it.”  

The Future of Water in Oklahoma Is Under Attack:

OUR TOUR OF KANSAS, OK and the Industrial Chicken Farms

GCSC members and All Souls Green Team members traveled in a van loaned to us by the All Souls Unitarian Church in Tulsa. We went on a rainy Saturday to take a tour of the Kansas, OK area out to see and smell some of the new mega Poultry Farms that are crowded around the historic local farms.  We were very fortunate to have the leader of the Green Country Guardians, Pam Kingfisher, as our guide.  The Green Country Guardians are a volunteer activist group working to save their local farms, their local water supply and the clean, non-polluted river waters in Northeast Oklahoma.

We are continuing to fight the state government who keeps granting permits with little review that reusults in unhelthy conditions for the local people who live and recreate there.
