The Climate Change Accountability Act is a Private Member's Bill that has been submitted in the 39th, 40th and 41st Canadian Parliament. It was originally tabled in October 2006 in the Canadian House of Commons as Bill C-377 of the 39th Parliament by Jack Layton, then the leader of the New Democratic Party of Canada (NDP). It passed third reading by a vote of 148 to 116 with the support of caucuses of the Liberal Party of Canada, the Bloc Québécois and the NDP (the Conservative Party of Canada, led by Prime Minister Stephen Harper, voted against it). However, Bill C-377 died as it was still before the Senate when Parliament was dissolved for the 2008 Canadian federal election.
