What Is a Carbon Tax

Simply put, a carbon tax is an environmental fee levied by governments on the production, distribution or use of fossil fuels such as oil, coal and natural gas. The amount of the tax depends on how much carbon dioxide each type of fuel emits when it is used to run factories or power plants, provide heat and electricity to homes and businesses, drive vehicles and so on. How Does a Carbon Tax Work? Essentially, a carbon tax—also known as a carbon dioxide tax or CO2 tax—is a tax on pollution: the more a company pollutes, the higher tax it pays. It is based on the economic principle of negative externalities. In the language of economics, externalities are costs or benefits created by the production of goods and services, so negative externalities are unpaid costs. When utilities, businesses or homeowners use fossil fuels, they generate greenhouse gases and other types of pollution that carries with it a cost for society, because pollution affects everyone.  Pollution affects people in different ways, including health effects, degradation of natural resources, down to less obvious effects like depressed property value.  The cost we bear for carbon emissions is an increase in atmospheric greenhouse gas concentration, and as a consequence, global climate change. A carbon tax factors the societal cost of greenhouse gas emissions into the price of the fossil fuels that create them—so the people who cause the pollution have to pay for it.   To simplify the application of a carbon tax, the fees can be applied to the fossil fuel directly, for example as an extra tax on gasoline. How Does a Carbon Tax Promote Renewable Energy? By making dirty fuels like oil, natural gas, and coal more expensive, a carbon tax encourages utilities, businesses, and individuals to reduce energy consumption and increase energy efficiency. A carbon tax also makes clean, renewable energy from sources such as wind and solar more cost-competitive with fossil fuels, favoring investments in those technologies. How Can a Carbon Tax Reduce Global Warming? A carbon tax is one of two market-based strategies—the other is cap and trade—aimed at reducing greenhouse gas emissions and slowing global warming. The carbon dioxide created by burning fossil fuels gets trapped in the Earths atmosphere, where it absorbs heat and creates a greenhouse effect that leads to global warming—which scientists believe is causing significant climate changes. As a result of global warming, polar ice caps are melting at an accelerating rate, which contributes to coastal flooding worldwide and threatens habitat for polar bears and other species. Global warming also leads to more severe droughts, increased flooding, and more intense wildfires. In addition, global warming reduces the availability of fresh water  for people and animals who live in dry or desert areas. By reducing the release of carbon dioxide that is put into the atmosphere, scientists believe we can slow the rate of global warming. Carbon Taxes Are Being Adopted Worldwide A number of countries have instituted a carbon tax.  In Asia, Japan has had a carbon tax since 2012, South Korea since 2015. Australia introduced a carbon tax in 2012, but it was then repealed by a conservative federal government in 2014. A number of European countries have established carbon taxation systems, each with different characteristics.  In Canada, there is no country-level tax, but the provinces of Quebec, British Columbia, and Alberta all tax carbon.
