You may have already heard the big news that China and the U.S. have come to an ambitious agreement to cut carbon emissions and fight climate change. It’s a major achievement, and a welcome surprise after so many years of inaction.

It also provides some much needed hope after the midterm elections in the U.S., with Republicans now coming after the EPA and carbon regulation with their torches and pitchforks. Maybe this marks the beginning of a global sea change.

China and the U.S. are at the top of the global heap of carbon polluters, so a commitment to emissions reductions from these two countries could really go a long way in prompting other countries to make cuts.

The U.S. has pledged to emit at least 26 percent less carbon in 2025 than it did in 2005, and China has agreed to halt its emissions growth by 2030, if not sooner. These are ambitious goals, and to make them happen, both countries will have to make serious investments in carbon neutral energy sources.

That’s a good thing. Fingers crossed the newly Republican-controlled Congress sets aside the torches and pitchforks to make this happen.
