A recent news article about the Stern Report contained the following gem from a Bush administration spokeswoman:
The statement from spokeswoman Kristen Hellmer said the United States is "well on track to meet the president's goal to reduce greenhouse gas intensity of our economy 18 percent by 2012."
This statement makes it sound like the Bush administration is taking on the problem of climate change head-on, with an aggressive program to reduce emissions.
But it ain't so.
The statement is about greenhouse gas intensity rather than greenhouse gas emissions.
Greenhouse gas intensity is the emissions per unit economic output. Multiply this quantity by the size of the economy and you get total greenhouse gas emissions.
Historically, U.S. greenhouse gas intensity has declined all by itself as our economy has evolved from manufacturing (which takes a lot of energy) to services (which take less), and as equipment has naturally become more efficient. Over the past few decades, greenhouse gas intensity has declined somewhere between 1% and 2% per year.
At the same time, the economy has grown more rapidly than this, so total greenhouse gas emissions have increased.
Several years ago, the Bush administration committed itself to an 18% decrease in greenhouse gas intensity over a decade -- corresponding to a decrease of about 1.8% per year. This represents negligible if any increase in the natural rate of decline.
In other words, they basically committed the U.S. to maintaining the status quo.
Importantly, it is virtually certain that the economy will grow faster than this during the decade, so even if the target is met, greenhouse gas emissions will continue to rise. Considering that we need to reduce emissions by about 80% from today's levels to stabilize atmospheric CO2, achieving the administration's intensity target does nothing to stop global warming.

Comment by the atmosphere:
The atmosphere:
"You know, those humans were releasing all this CO2, and so I was going to heat up. But then I saw that the humans were like, so intense. Their lawyers, policy wonks and number-crunchers were working really hard. So I gave them a break and suspended the laws of physics."

what?
18% by 2012?
I didn't realize our greenhouse gas emissions were projected to decline at that rate. Given the amount of coal fire power stations we are building I would have expected an increase. Anyone have any more info on the yearly anthropogenic CO2 emissions and projections?

You're confusing intensity w/ emissions
Wacki-
Our emissions are NOT going down. The emissions intensity is going down. Our economy is growing fast enough that total emissions are still growing rapidly.
Regards.

Vacuum
Do you ever feel that you are screaming into a vacuum?
But maybe it is best we don't know we are already doomed.
Good luck guys, see you in " another time, another place, with another face"(Van Morrison)

If you're going to use the word, use quotes
Over the past few decades, greenhouse gas intensity has declined somewhere between 1% and 2% per year.
"Intensity" is such a contrivance of a word that I wouldn't use it without scare quotes. Just using it as if it were legitimate buys into the spin...

Snow Job
Tony Snow trotted out exactly this same malarkey yesterday at his press briefing, saying with straight face that the President, contrary to stereotypes, is actively engaged in trying to fight climate change. Transcript here: http://www.whitehouse.gov/news/releases/2006/10/20061031-...

confused
Does GHG intensity improvement mean that global warming has not yet reached the point where it is slowing economic growth?

Coal to liquid
Coal to liquid fuel and fuel farming emit more than twice the GHG per mile driven of fossil fuel. That will be a huge intensifier of GHG per unit of economic bullshit figuring by wall street/duuhbya friendly liars disguised as economists.
Not a good result.

Smart fuel cell
http://www.freep.com/apps/pbcs.dll/article?AID=/20070917/ ...
A smart fuel cell "island" grid design? Very good! and it runs on biogas or natural gas. That's distributed generation and storage.
This is the way to really reduce GHG. Fuel cell/turbines put out half the ghg per unit of energy.
