With the removal of Thomas Mulcair and a leadership race soon to come, there is renewed energy around Canada’s New Democratic Party. Adding to the excitement, the party delegates voted over the weekend — against the protests of members from Alberta, home of the tar sands — to debate the “Leap Manifesto,” a document with a number of high-profile supporters, including Naomi Klein.

Issued in 2015, the Leap Manifesto was written with contributions from environmental, indigenous, faith-based, and labor activists. It calls for public resources to effect a “just transition” to an environmentally sustainable economy, greater respect for indigenous self-determination, good-paying green jobs, and better public services.

Among its most controversial features within the NDP (and beyond) is its call for a moratorium on pipeline construction and its claim that Canada could be, with proper public investment, completely carbon-free by 2050.
