How do Emissions Trading Systems Work?

A practical method of lowering greenhouse gas emissions is emissions trading, commonly referred to as "cap and trade." Governments cap the maximum amount of emissions and issue permits, or allowances, for each unit of emissions permitted under the cap in order to encourage businesses to reduce their emissions. Each unit of an emitting company's emissions requires a permit, which must be obtained and returned. The government may issue them with licenses, or they may trade with other businesses. The permits may be given away without charge or sold at public auction by the government. In this article, we will discuss the emissions trading system.

What are Emissions Trading Systems?

The method of lowering pollution known as "emissions trading," sometimes known as "cap and trade" or "allowance trading," has been utilized to successfully safeguard both human health and the environment. A limit (or cap) on pollution and tradable allowances that are equivalent to the limit and allow holders of the allowances to emit a certain amount (such as one tonne) of the pollutant are the two main components of emissions trading schemes.

This cap makes sure the environmental objective is achieved, and the tradable allowances provide each emissions source the freedom to choose its own course for compliance. These initiatives are frequently referred to as "market-based" because permits can be purchased and sold on an allowance market.
The Environment Protection Authority (EPA) would implement such a plan by first calculating the total permissible emissions and then dividing this amount into tradeable units (often called credits or permits). Participants in the scheme are subsequently given access to these units.

Participants who produce harmful emissions must acquire enough tradable units to make up for those emissions. Those who cut emissions might have extra units they can sell to those who find cutting emissions more expensive or challenging.
By enabling emission reductions where they are most cost-effective to achieve, emission trading systems aid in economic efficiency. Polluters who would find it expensive to cut their emissions may purchase emission allowances from others who can do so more affordably. The costs of cutting other emissions units would be equalized in a "perfectly" functioning market, and the overall costs of achieving a certain environmental goal would be kept to a minimum.

Types of Trading Systems

There are two types of trading systems-

1. Cap-and-trade systems:-

An upper limit on emissions is fixed in a cap-and-trade system, and emission permits are either sold at auction or given away without charge in accordance with predetermined standards.

2. Baseline-and-Credit System:-

There is no set cap on emissions under a baseline-and-credit system, but polluters who lower their emissions more than they would otherwise be required to can earn "credits" that they can then sell to others who require them to meet rules to which they are subject.

Features of Emissions Trading Programs

Programs for exchanging emissions that are well-designed offer:

  • The total pollutant limit establishes environmental assurance.
  • Individual emissions sources should have the freedom to customize their compliance path to meet their needs.
  • Incentives for innovation and efficiency that reduce the costs of implementation.
  • The possibility to deposit surplus credits as a motivator for early emission reductions.
  • Low costs for administration.
  • Responsibility for emissions tracking, reporting, and reduction.
  • Concerns about the environment and/or public health affect a substantial portion of the world.
  • The pollution issue is caused by a sizable number of causes.
  • Emissions can be quantified regularly and precisely.

Which nations implement Emission Trading?

As was already noted, the EU ETS, or European Union emissions trading scheme, is now the biggest system in existence. It operates in all 28 EU member states, as well as Iceland, Liechtenstein, and Norway, and reduces emissions from more than 11,000 large energy consumers, including factories, power plants, and airlines that fly between ETS member states. It addresses about 45% of the EU's overall greenhouse gas emissions. A single, centralized quota encompassing the entire EU was established under the third phase of the ETS, which spans from 2013–20. Phase 4 reforms will cut this cap by at least 1.74% a year up to 2020 and by 2.2% annually starting in 2021 in order to better reach that goal.
There are 51 carbons pricing schemes now in place or planned worldwide, according to the World Bank's State and Trends of Carbon Pricing (May 2018). These include national-level carbon taxes as well as ETSs in Switzerland, South Korea, New Zealand, as well as various US states and Canadian provinces. According to the International Carbon Action Partnership (ICAP), 15% of global emissions are now covered by emissions trading.


A growing number of corporations are using the Emission Trading Scheme, a market mechanism that uses market forces to combat climate change by offering financial incentives to businesses that reduce their emissions by implementing more efficient procedures or using cleaner fuels. The ultimate environmental goal is thus accomplished in the most adaptable and economically advantageous manner for society. Setting an appropriate price on GHG emissions is crucial for internalizing the external cost of climate change in the widest range of economic decision-making processes and for creating financial incentives for environmentally friendly development.
