The Trudeau-McKenna Church of environmentalists of the last days has a plan to reduce the “carbon emissions” of Canada. They are called to fulfill the promises of the Paris Agreement, thus being a tax on energy.
It should be noted that you are not putting a price on pollution; In fact, a tax on all energy fuels is being imposed. In addition to this, CO2 is not established as a pollutant, it is a part of the atmosphere of our planet that gives life and in the same way improves it.
