Dear President Obama and Secretary Kerry,

As scientists and economists, we are concerned about climate change and its impacts. We urge you to reject the Keystone XL tar sands oil pipeline as a project that will contribute to climate change at a time when we should be doing all we can to put clean energy alternatives in place.

As you both have made clear, climate change is a very serious problem. We must address climate change by decarbonizing our energy supply. A critical first step is to stop making climate change worse by tapping into disproportionately carbon-intensive energy sources like tar sands bitumen. The Keystone XL pipeline will drive expansion of the energy-intensive strip-mining and drilling of tar sands from under Canada’s Boreal forest, increasing global carbon emissions. Keystone XL is a step in the wrong direction.

President Obama, you said in your speech in Georgetown last year that “allowing the Keystone pipeline to be built requires a finding that doing so would be in our nation’s interest. And our national interest will be served only if this project does not significantly exacerbate the problem of carbon pollution.”

We agree that climate impact is important and evidence shows that Keystone XL will significantly contribute to climate change. Fuels produced from tar sands result in more greenhouse gas emissions over their lifecycle than fuels produced from conventional oil, including heavy crudes processed in some Gulf Coast refineries. As the main pathway for tar sands to reach overseas markets, the Keystone XL pipeline would cause a sizeable expansion of tar sands production and also an increase in the related greenhouse gas pollution. The State Department review confirmed this analysis under the scenario that best meets the reality of the opposition to alternative pipeline proposals and the higher costs of other ways of transporting diluted bitumen such as rail. The review found:

“The total lifecycle emissions associated with production, refining, and combustion of 830,000 bpd of oil sands crude oil is approximately 147 to 168 MMTCO2e per year. The annual lifecycle GHG emissions from 830,000 bpd of the four reference crudes examined in this section are estimated to be 124 to 159 MMTCO2e. The range of incremental GHG emissions for crude oil that would be transported by the proposed Project is estimated to be 1.3 to 27.4 MMTCO2e annually.”
To put these numbers into perspective, the potential incremental annual emissions of 27.4 MMTCO2e is more than the emissions that seven coal-fired power plants emit in one year. And over the 50-year expected lifespan of the pipeline, the total emissions from Keystone XL could amount to as much as 8.4 billion metric tons CO2e. These are emissions that can and should be avoided with a transition to clean energy.

The contribution of the Keystone XL tar sands pipeline to climate change is real and important, especially given the commitment of the United States and other world leaders to stay within two degrees Celsius of global warming. And yet, the State Department environmental review chose an inconsistent model for its “most likely” scenarios, using business-as-usual energy scenarios that would lead to a catastrophic six degrees Celsius rise in global warming. Rejecting Keystone XL is necessary for the United States to be consistent with its climate commitments. Six degrees Celsius of global warming has no place in a sound climate plan.

Secretary Kerry, in your speech in Jakarta, you said, “The science of climate change is leaping out at us like a scene from a 3D movie – warning us – compelling us to act.” Rejecting the Keystone XL tar sands pipeline would be a decision based on sound science.

The world is looking to the United States to lead through strong climate action at home. This includes rejecting projects that will make climate change worse such as the Keystone XL tar sands pipeline.

The list of signatories is below the fold.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
