Justin Trudeau announced another of his Liberal government’s green plans in December. I have lost track of how many green plans we have had, but not a single one has met its targets. With the prime minister set to officially meet with the new U.S. president Tuesday, the Liberals’ environmental agenda looks embarrassingly unambitious by comparison.

Raising the price of carbon is one of the pillars of the government’s latest plan to reduce greenhouse gas emissions. But there are no magic bullets and piecemeal measures don’t work.

In other regions that have carbon pricing mechanisms, such as the European Union and China (with its pilot schemes), climate change abatement plans consist of many complementary measures, including stringent legislation.
