Except it’s missing key facts: there are many policies in the climate plan in addition to carbon pricing and spending. The plan is estimated to reduce GHGs by another 10MT. The 5MT is just the direct impact of the price, which is low.
The reductions from the rest of Ontarians climate plan mean that keeping the plan and cap and trade would yield far more reductions than just a carbon tax at a lower cost. Some GHG reductions happen elsewhere but it’s smaller share than suggested here.
Besides, if economists believe markets allow for most cost effective reductions, why not accept those reductions even if they are in another jurisdiction? You like open markets for other things, no? Its enviros like me that should be skeptical about trading across jurisdictions
