Carbon Tax and Emissions Trading System

Carbon tax and emission trading systems (ETS) are two primary types of carbon pricing instruments. Carbon tax refers to a policy tool aimed at reducing GHG emissions by setting a price on them. The government sets a price per ton of emissions, to promote low-carbon alternatives and innovative green technologies. The outcome of emission reduction of a carbon tax is not defined, however the carbon price is, unlike the ETS.

ETS, commonly referred to as cap-and-trade system, is also a carbon pricing approach toward emissions reduction. In this market-driven system, a regulator sets a threshold for GHG emissions from various sectors of an economy. It allows the trading of emission allowances to entities in the ETS to stay within the emission limits, while allowing flexible carbon rates.

Both carbon pricing systems are widely adopted across many nations and jurisdictions around the world, serving as a tool to reduce emissions of a country by setting a price or threshold for emissions.

Carbon Pricing Systems Around the World

According to the World Bank, revenue generated from carbon taxes and emissions trading systems (ETS) reached nearly $95 billion in 2022, despite the high inflation, energy crises, and fiscal pressures. As of 2023, 23% of the global GHG emissions are covered by 73 carbon pricing instruments.

Many nations and regions around the world have adopted different carbon pricing systems. For instance, the European Union ETS was launched in 2005 for the EU member nations along with countries including Iceland, Lichtenstein, Norway, and Northern Ireland. The EU ETS is currently in its fourth trading phase (2021-2030). According to the European Union, the member states aim to reduce carbon emissions by 55% by 2030, compared to 1990 levels, and become carbon neutral by 2050. Since its launch, the EU ETS has reduced emissions from power plants and industries by 37%.

The United States does not have a national carbon tax or ETS. However, eleven states in the country are participants of the cap and trade system established in 2009, the Regional Greenhouse Gas Initiative. The members include New York, New Jersey, Connecticut, Massachusetts, New Hampshire, Maine, Maryland, Delaware, Pennsylvania, Rhode Island, and Vermont. The RGGI requires the participant states with 25 MW fossil fuels power generators to have allowances equal to their carbon emissions over a three-year period. The CO2 cap for the participating states is 157,184,044 CO2 allowances for 2024.
