Bob Perkowitz, of ecoAmerica — most recently in the news for recommending that the Obama Administration change its climate rhetoric — asserts in the Guardian that fossil fuel interests are spending one billion dollars this year to defeat cap and trade. Now I know that a billion is not what it used to be, but this is serious money.

Liberal and environmental organisations, as well as the major corporations that support climate change legislation, say they are being vastly outspent by fossil fuel interests.

“These guys are spending a billion dollars this year convincing Americans that they are clean, green, cuddly and warm,” said Bob Perkowitz, founder of the eco- America PR firm. Perkowitz is to brief the White House yesterday on a new environmental messaging strategy. “The enviros are getting their message out, but they are being outspent by 10 to one.” he said.On advertising, the ratio is about three to one. The oil and coal industry spent $76.1m on ads from 1 January to 27 April, according to CMAG data seen by the Guardian. Environmental groups, led by Al Gore’s Alliance for Climate Protection, the Environmental Defence Fund and the Sierra Club, spent $28.6m on ads in the same period, Tracey said.

Despite its global significance, the fate of the draft “cap and trade” bill now lies in the hands of just a dozen Democrats, who have yet to back Obama’s energy transformation. The Democratic leadership cannot take their support for granted. Seven of those pivotal Democrats received campaign donations in excess of $100,000 from the oil and gas industry, coal producers, and electricity firms during last year’s elections, according to an analysis provided to the Guardian by the Centre for Responsive Politics. Another two received more than $90,000 last year.

Environmentalists say those Democrats, who hold the balance of power on the committee, pose a far greater threat to the chances of passing climate change legislation than a full vote in the House of Representatives. “If they can get that bill through the subcommittee what is going to emerge is a piece of legislation,” said Tony Kreindler of the Environmental Defence Fund. “So this is ground zero for the vote.”

My sense is that Tony Kreidler might want to revisit his high school civics text book and look up “bicameral” in the index.
