RGGI (pronounced “Reggie”), the Regional Greenhouse Gas Initiative, has capped carbon dioxide emissions in ten northeastern U.S. states. Well, it isn’t much of a cap, given how loose it really is. Still, the latest analysis that tries to follow the money points to $1.6 billion in economic benefits for the economies in these ten states.

And it’s good for customers, too. They will save $1.3 billion on electric and gas bills in the next decade due to energy efficiency measures financed through RGGI money.

Win. Win. Win.
