It is ridiculous to believe that Trudeau's carbon tax will stop the rise in manmade GHG emissions.  We know that the demand for carbon-intensive products, such as gasoline, is relatively inelastic.  That is an increase in price leads to a relatively small decline in demand.  BC has had a carbon tax for years and GHGs there continued to rise.

However, it serves the purpose of making the Liberals feel good about themselves.  And perhaps a celebratory glass of champagne at the next international climate conference.
