The Keystone XL pipeline would connect the tar sands in Alberta, Canada to oil refineries on the Gulf Coast. It would stretch 1,700 miles and cross 6 states, threatening freshwater supplies in America's agricultural heartland and deepening our dependence on some of the dirtiest energy on the planet.

Keystone XL must be stopped. And we're not going away until it is. Take this pledge to add your voice and to join us for future actions.

Last year, thousands stepped up to oppose Keystone XL. 12,000 people circled the White House, and over 1,200 people were arrested in the greatest act of civil disobedience seen in decades. Against the longest possible odds, we prevailed, and this past January the Obama administration sent TransCanada back to the drawing board.

But the zombie pipeline still isn't dead, so now it's time to get back in the streets. This month, a coalition of civil society organizations will hold another rally at the White House—and this one won't be the last. With the election freshly behind him, President Obama needs to know that we're still here, and that we will still hold him to the promises he made way back in 2008. If he's serious about tackling climate change, the President needs to reject Keystone XL once and for all.
