Folks like you are the backbone of the movement to ensure wildlife and wild places are protected, clean air and water are accessible to all and devastating effects of climate change are fought. Give today to continue this vital work.
The Sierra Club dates back to 1892 and is the oldest and largest environmental advocacy organization in North America. Our mission is to explore, enjoy, and protect the planet. Since 1992, the Delaware Chapter has blazed trails to protect the environment and to provide opportunities to enjoy and explore the natural beauty of our state.
As a volunteer-run grassroots organization, we are working to protect our air and water quality and supporting state legislation and policies to reduce the negative impacts from climate change on those precious resources now and in the future.
2026 End of Session Recap
Another busy year in the Delaware General Assembly for the environment, with some amazing bills that are going to do amazing things for our state, as well as bills that we had to oppose because of the harm they would have caused to our state and communities.
In total, we worked on 25 bills and resolutions this year on issues that included (you can click on the subject to jump to the associated issue):
Energy bills are up again, but why? As we did last year, we put out a series of short videos that break down why energy prices are going up, and why they are likely to continue going up in the future unless we drastically correct course and bring more clean power online in Delaware.
We also go over some more misinformation being put out by fossil fuel front groups and misinformed legislators. We also share some information on how Data Centers will raise rates for Delaware Electric Co-op and DEMEC (municipal energy utility) customers, even when data centers are in New Castle County. Check it out below!
Right now, about 50% of our members are not receiving our emails! That is usually because when you unsubscribe from a national Sierra Club (or partner) email, they automatically unsubscribe you from our Chapter emails as well. I know, it's frustrating, to say the least. However, you can easily fix it so you can receive JUST our emails.
