![]() ![]() Two common economic alternatives to carbon taxes are tradable permits/credits and subsidies.Ĭarbon dioxide is one of several heat-trapping greenhouse gases (others include methane and water vapor) emitted as a result of human activities. Ī carbon tax as well as carbon emission trading is used within the carbon price concept. To make them more progressive, policymakers can try to redistribute the revenue generated from carbon taxes to low-income groups by lowering income taxes or offering rebates, then as part of the politics of climate change the overall policy initiative can be referred to as a carbon fee and dividend, rather than a tax. On their own, carbon taxes are usually regressive, since lower-income households tend to spend a greater proportion of their income on emissions-heavy goods and services like transportation than higher-income households. As of 2019, carbon taxes have been implemented or scheduled for implementation in 25 countries, while 46 countries put some form of price on carbon, either through carbon taxes or emissions trading schemes. Seventy-seven countries and over 100 cities have committed to achieving net zero emissions by 2050. Many economists argue that carbon taxes are the most efficient (lowest cost) way to tackle climate change. Research shows that carbon taxes effectively reduce emissions. Carbon taxes are thus a type of Pigovian tax. This negative externality can be reduced by taxing carbon content at any point in the product cycle. Greenhouse gas emissions cause climate change, which damages the environment and human health. When a hydrocarbon fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to COĢ. In its simplest form, a carbon tax covers only CO 2 emissions however, it could also cover other greenhouse gases, such as methane or nitrous oxide, by taxing such emissions based on their CO 2-equivalent global warming potential. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. In this way, they are designed to reduce greenhouse gas emissions by increasing prices of the fossil fuels that emit them when burned. Carbon taxes are intended to make visible the "hidden" social costs of carbon emissions, which are otherwise felt only in indirect ways like more severe weather events. A carbon tax would tax the CO 2 emitted from the power station.Ī carbon tax is a tax levied on the carbon emissions required to produce goods and services.
