Arizona’s retiring Senator Jeff Flake—who last month called the IPCC report on climate change “pretty dire”—joined Delaware’s Sen. Chris Coons to introduce the Senate companion to the Energy Innovation and Carbon Dividend bill championed in the House by Reps. Brian Fitzgerald, Francis Rooney and Dave Trott.

Both this bill and the House version would impose a tax of $15 per ton of carbon dioxide, increasing $10 each year, rising to nearly $100 per ton by 2030. The revenue from the tax would be rebated to American households via a dividend check.

This is not Flake’s first carbon tax bill. He co-sponsored carbon tax legislation in 2009 with…Bob Inglis.
