Mr. Speaker, what a ridiculous answer.
Last week, the environment minister refused to answer a very simple question at committee, so I will give her another chance.
It is a truism that environmental programs should have specific and measurable outcomes. We know how much scrubbers on smokestacks reduce SO2. We know how much a waste-water treatment plant will improve water quality. It is shocking that the Liberals do not know how much a carbon tax will reduce emissions.
By how much will a $50 a tonne carbon tax across Canada reduce our greenhouse gas emissions? I want a number.
