Allowance prices for carbon emission trade in all major emission trading schemes in Euro per ton of CO2 emitted (from 2008 until August 2024) Carbon emission trading (also called carbon market, emission trading scheme (ETS) or cap and trade) is a type of emissions trading scheme designed for carbon dioxide (CO 2) and other greenhouse gases (GHGs).
A comprehensive, upstream, auctioned cap-and-trade system is very similar to a comprehensive, upstream carbon tax. Yet, many commentators sharply contrast the two approaches. The main difference is what is defined and what derived. A tax is a price control, while a cap-and-trade system is a quantity control instrument. [54]
The European Union Emissions Trading System (EU ETS) is a carbon emission trading scheme (or cap and trade scheme) that began in 2005 and is intended to lower greenhouse gas emissions in the EU. Cap and trade schemes limit emissions of specified pollutants over an area and allow companies to trade emissions rights within that area.
The economics of carbon pricing is much the same for taxes and cap-and-trade. Both prices are efficient; [ a ] they have the same social cost and the same effect on profits if permits are auctioned. However, some economists argue that caps prevent non-price policies , such as renewable energy subsidies , from reducing carbon emissions , while ...
This cap-and-trade system sets emission limits to control and reduce greenhouse gases across the EU. [4] In the EU ETS cap-and trade system, companies receive or buy emission allowances within the cap and they are allowed to trade them with one another. The total number of allowances is limited, which ensures that they have a value.
At the 2024 meeting of the North American Carbon World, Director of the Washington State Department of Ecology, Laura Watson, suggested that the result of the reason for the sudden drop in settlement price for carbon allowances in the first auction of the year was a result of the initiative getting on the ballot.

Many economists argue that carbon taxes are the most efficient (lowest cost) way to tackle climate change. [8] [9] As of 2019, carbon taxes have either been implemented or are scheduled for implementation in 25 countries. [10] 46 countries have put some form of price on carbon, either through carbon taxes or carbon emission trading schemes. [11]
The matrix denotes four market policies: the (1) carbon tax, (2) carbon subsidy, (3) cap and trade, and (4) global carbon reward. The left side of the carbon pricing matrix is consistent with Arthur C. Pigou’s 1920 treatise on externalised costs and his proposed method of pricing negative externalities with taxes, and pricing positive ...
