"Companies can no longer hide their climate risk"
Nothing that a few millions of dollars purchase of carbon credits will take care of their emissions, allow them to not only increase their pollution but sell the credits to some other companies. 
That a boy.
Not even revenue neutral, it can be used as the Trudeau's government wishes, luxurious traveling, liberal party coffers, dubious feminist, islamic causes, you name it, the sky is the limit. Untraceable money, billions of it, coming in the tons like a mexican drug cartel revenue.
This will take care of controlling carbon emissions.
Ha!
