Those who oppose the approval of the pipeline have many arguments at their disposal. The pipeline, which will pass through several American states, is believed by many to result in environmental degradation while also causing the release of tons of carbon into the air. Besides the environmental risks, they point at the findings that this project will not result in significant job creation. Despite TransCanada's study commissioned in 2010 illustrating that Keystone XL will help create hundreds of thousands of jobs, the recent Department of State's findings show that about 4,000 temporary construction jobs and only 35 permanent jobs will be created. The energy security argument has been weakened by the steadily increasing oil production in the country and lower oil prices. The focus is now on the current administration's commitment to the clean energy future and to combating climate change. Domestically and abroad, many believe that the rejection of Keystone XL is important because it will send a clear message that the United States is serious about climate change.
Whether or not the pipeline project is approved in the U.S., the Canadian tar sands industry will continue to expand its operations and export opportunities. Canadian energy companies are already looking for ways to diversity and have proposed pipelines to other markets. For instance, Chinese companies have invested billions of dollars in the Canadian tar sands industry with exports to Asia in mind. At the same time, Canada has been working on improving its energy industry's image and demonstrating its commitment to environmental responsibility. From 1990 to 2010, Canadian energy industry's greenhouse gas emissions per barrel of oil sands crude decreased by 26%. The industry has also improved its clean up and water use methods.
Tar sands will continue to be developed. If not to the U.S., crude from tar sands will be exported elsewhere around the world. The current debate over the project can be seen as a matter of balancing environmental and economic concerns in the United States. Whether the final decision will be based on practical or more symbolic reasons remains to be seen.
