The Treasury Department’s Office of Environment and Energy has finally begun to turn over documents about its preparations for a carbon tax in response to transparency warrior Chris Horner’s Freedom of Information Act request. The documents provide solid evidence that the Obama administration and its allies in Congress have every intention of implementing a carbon tax if we fail to stop them.

The Office of Environment and Energy, if you’ve never heard of it, is housed in Treasury’s Office of International Affairs and exists principally to wait for authority to administer the revenue from a cap-and-trade scheme or carbon tax. And, apparently, to trick Americans into supporting the tax to provide it the money.  So the documents they’ve reluctantly released are worth a careful look.

There’s the G-20 report titled “Mobilizing Climate Finance,” which pegs the price tag at $2.1 trillion “of investment requirement” in a “global carbon market.”
