    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).

  3. Emissions trading - Wikipedia

    en.wikipedia.org/wiki/Emissions_trading

    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]

  4. European Union Emissions Trading System - Wikipedia

    en.wikipedia.org/wiki/European_Union_Emissions...

    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.

  5. Carbon price - Wikipedia

    en.wikipedia.org/wiki/Carbon_price

    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 ...

  6. EU Allowance - Wikipedia

    en.wikipedia.org/wiki/EU_Allowance

    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.

  8. Carbon tax - Wikipedia

    en.wikipedia.org/wiki/Carbon_tax

    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]

  9. Carbon offsets and credits - Wikipedia

    en.wikipedia.org/wiki/Carbon_offsets_and_credits

    Carbon offsetting is a carbon trading mechanism that enables entities to compensate for offset greenhouse gas emissions by investing in projects that reduce, avoid, or remove emissions elsewhere. When an entity invests in a carbon offsetting program, it receives carbon credit or offset credit , which account for the net climate benefits that ...
