Keystone XL oil pipeline could increase pollution more than thought

Nature : According to a recent study , the proposed Keystone XL oil pipeline could result in four times the carbon emissions estimated by the US State Department. The researchers say the government study did not take into account the fact that the pipeline would lead to an increase in oil production, which would cause global prices to drop and global use to rise. As a result, global greenhouse gas emissions could increase by as much as 110 million tons per year, compared with the 27 million tons estimated by the US State Department. At least one critic of the proposed pipeline says that economics aside, the project should be canceled to discourage the building of other similarly polluting projects.
