Climate Change

Climate change occurs when long-term weather patterns begin to shift. These periods of change have occurred throughout the Earth’s history over extended periods of time. However, since the Industrial Revolution the world has been warming at an unprecedented rate. Because of this, the current period of climate change is often referred to as “global warming.” Human activities that release heat-trapping greenhouse gases, such as the burning of fossil fuels, are largely responsible for this increased rate of change. The implications of this global increase in temperature are potentially disastrous and include extreme weather events, rising sea levels and loss of habitat for plants, animals and humans. In Canada, efforts to mitigate climate change include phasing-out coal-fired power plants in Ontario and instituting a carbon tax in British Columbia.

Carbon Pricing in Canada

Carbon pricing refers to a cost that is imposed on the combustion of fossil fuels used by industry and consumers. Pricing can be set either directly through a carbon tax or indirectly through a cap-and-trade market system. A price on carbon is intended to capture the public costs of greenhouse gas (GHG) emissions and shift the burden for damage back to the original emitters, compelling them to reduce emissions. In 2016, Prime Minister Justin Trudeau announced a national climate change policy that includes a system of carbon pricing across Canada. Provinces can either create their own systems to meet federal requirements or have a federal carbon tax imposed on them. Nine provinces and territories have their own carbon pricing plans that meet federal requirements. Ottawa has imposed its own carbon tax in Alberta, Saskatchewan, Manitoba and Ontario.
