As criticism of the carbon tax continues, a University of British Columbia professor says there is evidence that it has reduced greenhouse gas emissions. Kathryn Harrison, a political science professor at UBC, says since B.C. implemented its carbon tax 10 years before the federal tax was rolled out, researchers were able to look at whether B.C.’s emissions changed following the policy. …“There have been, by my count, about 15 studies that found that B.C.’s Carbon Tax lowered emissions below what it otherwise would have been, didn’t hurt the economy, was fair, but what we also know is that we can’t get the kind of emissions reductions that we’re committed to at $30 a tonne that’s why we need that steadily increasing price schedule.” A 2023 article looking at studies on B.C.’s carbon tax say research indicates that the policy has been a success.
