Try an action today

Like most Americans, you’re probably concerned about global climate change. And maybe a bit overwhelmed too. Many of us have put off taking significant action or even when we did, felt we should do more.

But the reality is that we each have so much we can do. Let’s start by putting pressure on our elected representatives and then follow that up with additional actions. Add up all the choices we make in a year or a lifetime - multiplied by all the people we influence along the way - and we have real impact.

For this website, the Sustainability, Energy and Environment Community (SEEC) answers the questions most frequently asked by those willing to act. What are the most important actions for us to take? What’s doable? What’s next? And how can we find out without reading through multiple lengthy sources?
