Last week the White House signaled to the world that this administration is serious about climate change.

At a global summit on climate last week, President Biden made a clear break from his predecessor, announcing ambitious new greenhouse gas emission standards for the U.S. In setting such a high target, Biden says he hopes to push this country – and others– to make the necessary changes to address the urgency of a warming planet.

But reaching the Biden administration’s goal of reducing greenhouse gas emissions by 50 to 52 percent by the year 2030 would require a remaking of this country’s economy, not to mention Congressional approval.
