By most accounts, oil from tar sands is 15 to 20 percent dirtier than conventional petroleum, and the process of extracting and refining it is more difficult and resource-intensive. With so many cleaner alternatives, there is no reason to embrace the use of a dirtier fuel source.Approving the pipeline would send a clear signal to the markets to expand the development of tar sands oil. Such an expansion would hurt our nation’s work to reduce carbon emissions. We have to make energy cleaner tomorrow than it is today. That’s why the president should block Keystone.
Being cleaner doesn’t mean we have to abandon carbon-based energy. As governor of Virginia, I supported building a state-of-the art coal plant in exchange for converting a plant that predated the Clean Air Act from coal to natural gas. I support development of offshore energy (gas, oil, wind and tidal) in the Atlantic. I support new hydro-fracturing techniques that expand the production of natural gas. And I believe that recent upgrades in national fuel economy standards are a major environmental achievement for Obama. We just need to take a phased approach to reducing carbon emissions.
Coal plants, fossil-fuel production and automobiles still pollute. But we’ve shown that we can get progressively cleaner.
The United States has reduced carbon dioxide emissions by 9 percent since 2005. Although the recession played a part, the volume of fuel use switched over to natural gas during this period was unprecedented, and renewable-electricity generation — particularly wind — has grown faster than expected. Better auto fuel efficiency has played a part and will continue to have an increasing role.
Few could have foreseen that the United States would reduce emissions to this degree. And we’ve done it through smart policies and innovation. I hope we can learn from this and keep moving in the right direction.
But tar sands oil is the opposite of an innovative, make-it-cleaner approach. It represents a major backslide. Why would we embrace a dirtier energy source when smart innovation and policy are opening up so many cleaner alternatives?
I explained my thoughts to a manufacturing executive recently, and he said: “I understand your point about Alberta tar sands oil, and even agree, to some extent. But it will be mined, refined, shipped and used by someone. Shouldn’t we try to benefit from it in America?”
I have two responses. First, we may not be able to control what other nations do, but that’s no reason to embrace a lowest-common-denominator approach. Second, if release of the tar sands oil were inevitable, the pipeline wouldn’t be such a big deal. If it were just as easy to ship this oil via road or rail, proponents wouldn’t be pushing so hard.
There’s a longer-term answer, too. Someday when I am long retired from the Senate and kids ask me what I did for energy and the environment, I want to tell them a story about how the United States led the way with innovative solutions that created jobs, reduced pollution and tackled our energy challenges head-on.
I hope the president gets to tell that same story long after he’s out of office.
