Quebec Premier François Legault will be hosted by Gov. Gavin Newsom in Sacramento to discuss reducing greenhouse gases. Today’s closed-door meeting comes as the Trump administration accuses California of overstepping its bounds by entering into an international emissions agreement. Remind me: California’s cap-and-trade program has been around since 2013 and aims to limit the state’s greenhouse gas emissions. Industries meet their goals by lowering emissions or buying state-auctioned permits that allow them to pollute. The permits can be bought and sold.
