Pollution trading, also known as emissions trading, is a market-oriented approach to controlling pollution. It provides economic incentives for reducing emissions of pollutants. In a pollution trading system, a regulatory body establishes a limit on total emissions and issues permits that grant the right to emit a certain quantity of pollution, typically measured over a year. Companies can either use their permits to cover their emissions or reduce pollution and sell any excess permits to other firms, creating a market for pollution rights. This approach is often viewed as more efficient than traditional regulatory methods, as it allows businesses to determine the most cost-effective means of reducing emissions.
Characteristics and Values of Pollution Trading
| Characteristics | Values |
|---|---|
| Type | Market-oriented approach to controlling pollution |
| Other Names | Cap and trade, cap and invest, allowance trading, emissions trading scheme (ETS), market-based emissions reduction programs |
| Function | Puts a price on pollution, providing an economic incentive to reduce pollution |
| Cap | Maximum allowable emissions from a group of emissions sources; set by a central authority or governmental body |
| Permits | Allowances or credits that authorise emission of a specific quantity of a pollutant over a set time period; can be traded, sold, purchased, or banked |
| Polluters | Required to hold permits equal to their emissions; can buy permits from others if they want to increase emissions |
| Incentive | Provides incentive for polluters to reduce emissions; companies that reduce emissions can sell or trade permits for extra profit |
| Cost | Cost of permits is determined by market forces of supply and demand |
| Revenue | Revenue source for the government through auction of permits |
| Criticism | May lead to overproduction of pollutants up to maximum levels set by the government; emissions credits may be cheaper than converting to cleaner technologies |

What You'll Learn
Cap and trade
In a cap-and-trade program, the government sets a limit or cap on emissions permitted across a given industry. The government then issues a limited number of permits that allow companies to emit a certain amount of carbon dioxide and other pollutants. Each allowance permits a company to emit one ton of emissions. The government distributes these allowances to companies either for free or through an auction. However, the government lowers the number of permits each year, making the permits more expensive. Companies that produce emissions higher than their permits allow are taxed and may be penalized for violating the cap.
On the other hand, companies that reduce their emissions can sell their allowances or "trade" them to other companies that pollute more. They can also bank them for future use. This creates an exchange value for emissions and a new economic resource for industries. Proponents of cap and trade argue that it offers an incentive for companies to invest in cleaner technologies and alternative energy resources. It also allows the market to find the cheapest way to cut emissions.
Cap-and-trade programs have been implemented in various jurisdictions. For example, European countries have operated a cap-and-trade program since 2005, and South Korea became the first Asian country to implement a nationwide program in 2015. In the United States, California's cap-and-trade program has led to a steady decline in the state's carbon dioxide pollution.

Baseline and credit
Emissions trading programs are market-based approaches to controlling pollution by providing economic incentives for reducing emissions. One such approach is the baseline-and-credit system, which has been applied to various environmental issues, including climate change mitigation, water quality improvement, and biodiversity conservation.
In a baseline-and-credit program, polluters can create permits, called credits or offsets, by reducing their emissions below a baseline level, which is often based on historical emissions data. These credits can then be traded on environmental markets, with prices determined by supply and demand. The financial incentive provided by the trading aspect encourages entities to reduce their environmental footprint, and the flexibility of the system allows for cost-effective solutions.
To ensure the integrity of the baseline-and-credit system, robust monitoring and verification mechanisms are essential. This involves the regular monitoring of environmental performance and independent verification of reported data to prevent fraud and ensure compliance. The success of baseline-and-credit systems depends on careful design and implementation, including setting an appropriate baseline and implementing rigorous monitoring and verification protocols.
The EU Emissions Trading System (EU ETS) is an example of a successful baseline-and-credit system, which has helped reduce greenhouse gas emissions within the European Union. However, challenges have been observed in some voluntary carbon offset programs, where issues with additionality and verification have undermined the environmental integrity of credits issued.
While baseline-and-credit systems offer flexibility and incentives for emissions reduction, some studies suggest that emissions and output may be inefficiently high under this approach compared to a corresponding cap-and-trade plan. This highlights the importance of careful design and the potential need for complementary measures to ensure effective emissions reduction outcomes.

Pollution tax
Pollution trading, also known as emissions trading, is a market-oriented approach to controlling pollution. It provides economic incentives for reducing the emissions of pollutants. One example is carbon emission trading, which is a tool for climate change mitigation.
The four main categories of environmental taxes are energy, transport, pollution, and resource taxes. Energy taxes can be levied on the production, distribution, or consumption of energy sources, particularly fossil fuels. They aim to influence energy consumption patterns, promote energy efficiency, and encourage the transition to cleaner and more sustainable energy sources. Pollution taxes incorporate taxes on measured emissions to air and water, as well as the management of waste and noise pollution. An exception is CO2 taxes. For example, Ireland levies a tax on plastic bags at the point of sale, successfully reducing their consumption and contributing to a significant decrease in litter pollution.
The potential benefits of pollution taxes include their ability to raise revenue, which can be used for environmental cleanup, research and development of clean energy technologies, or to finance reductions in pre-existing taxes. Pollution taxes can also improve the competitiveness of renewable energy sources and other low-carbon energy sources, as well as encourage energy conservation and the adoption of energy-efficient appliances and processes.
However, there are also potential drawbacks to pollution taxes. One concern is the social impact, as an increase in energy prices can disproportionately affect low-income households. Additionally, setting the correct taxation level can be challenging and may lead to distortions or unintended consequences.

Emissions trading programs
The two key components of emissions trading programs are the emissions cap and tradable allowances. The cap, also known as the emissions limit or budget, sets the maximum allowable emissions from a group of emission sources. This cap is intended to incentivize effective pollution control and protect public health and the environment. The allowances are authorizations to emit a specific unit of emissions (e.g., one ton) over a particular period. These allowances can be traded, sold, or purchased in the market, providing flexibility for emission sources to choose their compliance approach.

Allowance trading
The government distributes these allowances to companies, either for free or through an auction. The number of permits is lowered each year, making them more expensive over time. Companies that reduce their emissions can sell or trade their allowances to other companies that pollute more, creating a new economic resource for industries. This incentivises companies to reduce emissions more efficiently and invest in clean technology as permits become more costly.
However, critics argue that cap and trade could lead to an overproduction of pollutants up to the maximum levels set by the government. This is because allowable levels may be set too generously, and emissions credits are often cheaper than converting to cleaner technologies.

Frequently asked questions
Pollution trading, also known as emissions trading, is a market-oriented approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants.
A regulatory body, such as a government, establishes a limit on total emissions and issues permits that grant companies the right to emit a certain quantity of pollution, typically measured over a year. Companies can then choose to use their permits to cover their emissions or reduce pollution and sell any excess permits to other companies.
Pollution trading provides flexibility and economic incentives for companies to reduce their emissions. It also allows companies to decide the most cost-effective means of reducing emissions, fostering innovation and flexibility in pollution control strategies.
One potential drawback of pollution trading is that it could lead to an overproduction of pollutants up to the maximum levels set by the regulatory body. Additionally, the trade mechanism may not always be followed, and credits or permits may be given away for free, removing the incentive for companies to reduce their emissions.
