America's Fossil Fuel Fight

Early this year US climate campaigners claimed a totemic victory when president Obama used his veto to block the approval of the Keystone XL pipeline. This proposed pipeline would carry dirty Canadian tar sand crude oil to refineries along the Gulf coast.
While the battle is far from over - what with Republicans vowing to continue pushing for its approval - Obama’s decision holds strong strategic significance in the fight to keep fossil fuels in the ground.
However, the Keystone XL drama may prove to be little more than a sideshow to American big oil’s ultimate ambition: to overturn the US crude oil export ban.
