Liberals to get help from NDP to get net-zero bill to Senate faster Poll yes By Mia Rabson, The Canadian Press on June 9, 2021. OTTAWA – NDP environment critic Laurel Collins says her party will help the Liberals get the government’s climate accountability bill to the Senate as soon as possible, even though the bill isn’t as good as she thinks it could be. The net-zero legislation sets legally binding greenhouse gas emission reduction targets over the next three decades, culminating in net zero emissions no later than 2050. That would mean Canada captures any emissions still produced using nature or technology, a critical requirement to the world’s attempt to slow global warming.
