UN Warns of Impending Climate Change Tipping Point

A report issued by the United Nations Intergovernmental Panel on Climate Change (IPCC) warned that for climate change to be kept to 1.5°C above pre-industrial levels, greenhouse gas emissions would need to be reduced at least 45 per cent (of 2010 emissions levels) by 2030 and 100 per cent by 2050. Otherwise, the most dire “climate-related risks to health, livelihoods, food security, water supply, human security, and economic growth” may not be avoided.

Carbon Pricing in Canada

Carbon pricing plans impose a cost on the combustion of fossil fuels by industries and consumers — either directly through a tax, or indirectly through a cap-and-trade system. In a market economy like Canada’s, prices help regulate the supply and demand of goods and services. By influencing the price of a commodity like gasoline, through carbon pricing, governments aim to discourage its use and thereby reduce the greenhouse gas emissions that result from its consumption.

In 2016, Prime Minister Justin Trudeau announced a national climate-change policy that included a system of carbon pricing across Canada. As of June 2019, eight provinces and territories have carbon pricing plans that meet the requirements of the national policy. In the remaining provinces — Saskatchewan, Manitoba, Ontario and New Brunswick — Ottawa imposed or intends to impose its own carbon tax. The tax has vocal opponents on the political right, including some premiers and party leaders.
