It Is Possible For the U.S. to Reduce Emissions 80% by 2050

So, I’ve got good news and bad news.

The good news: There is no substantial technical or economic barrier that would prevent the U.S. from reducing its greenhouse gas emissions 80 percent below 1990 levels by 2050, a target that would help put the world on track to limit global average temperature rise to 2 degrees Celsius. In fact, there are multiple pathways to that target, each involving a different mix of technologies. Achieving the goal would cost only around 1 percent of GDP a year out through 2050, and if we started now, we could allow infrastructure to turn over at its natural rate, avoiding stranded assets.

The bad news: Pulling it off would require immediate, intelligent, coordinated, vigorously executed policies that sustain themselves over decades. Y’know, like how America does. [cough]
