Organizations and markets have implemented various strategies to combat pollution and promote environmental sustainability. Governments and regulatory bodies play a crucial role in establishing standards and regulations to reduce pollution. For example, the US Environmental Protection Agency (EPA) provides guidance and assistance to states, issues national emissions standards, and reviews state plans to ensure compliance with the Clean Air Act. Additionally, local initiatives, such as the Minnesota Pollution Control Agency, offer programs to help businesses and communities reduce their environmental impact. Markets have also been utilized to address pollution through the creation of pollution rights licenses and trading systems, allowing for greater flexibility in achieving desired levels of pollution control. Furthermore, non-profit organizations like the Clean Air Task Force collaborate with governments and industries to develop policies and strategies for improving air quality and reducing climate change. These collective efforts demonstrate a commitment to tackling pollution and creating a more sustainable future.

What You'll Learn
Command-and-control policies
The main criticism of command-and-control policies is that they do not provide incentives for firms to go beyond the regulated level of pollution reduction. Firms are only encouraged to meet the regulated standard, and there is no economic motivation to further improve the environment. This inflexibility can hinder innovation and more efficient methods of pollution reduction.
Another drawback is that command-and-control regulations often have politically-motivated loopholes and exceptions. Existing firms may lobby for stricter standards to be applied only to new firms, leading to real-world environmental laws filled with fine print and compromises.
Despite these criticisms, command-and-control regulations have been successful in protecting and cleaning up the environment in certain contexts, such as in the United States during the late 1960s and early 1970s.
To address the shortcomings of command-and-control policies, hybrid approaches combining aspects of command-and-control and market-based incentive policies have been proposed and implemented. These approaches aim to provide the certainty of a given emissions standard while allowing firms to pursue the least costly abatement method. However, these hybrid approaches may not always be the most economically efficient solution.

Market-based policies
Subsidies are a common tool used by governments to encourage the adoption of new technology and reduce pollution levels. Governments can provide financial incentives in exchange for air pollution reductions and for the adoption of newer, cleaner technology. An example of a market-based transferable permit system is the cap-and-trade program, which has been successfully implemented in the Montreal Protocol and the Clean Air Act. This program sets a maximum level of pollution and economically encourages businesses to innovate so they can cash in on the permit market. However, cap-and-trade programs can result in pollution locality, where local pollutants like particulate matter can still build up under these policies.
Market-based instruments (MBIs) are policy instruments that use markets, price, and other economic variables to provide incentives for polluters to reduce or eliminate negative environmental externalities. MBIs seek to address the market failure of externalities (such as pollution) by incorporating the external cost of production or consumption activities through taxes or charges on processes or products. MBIs can be implemented systematically across an economy or region, or by environmental medium (e.g. water).

Cap-and-trade programs
The cap-and-trade approach was first demonstrated in a series of micro-economic computer simulation studies between 1967 and 1970 for the National Air Pollution Control Administration. These studies compared the cost and effectiveness of various control strategies, and it was found that the cap-and-trade approach was significantly less costly than conventional abatement strategies. The first "'cap-and-trade" system was later launched as part of the US Acid Rain Program in the 1990 Clean Air Act, which successfully reduced acid rain.
One advantage of cap-and-trade programs is that the level of pollution after implementation is predetermined, and businesses are economically encouraged to innovate so they can benefit from the permit market. For example, in the European Union's Emissions Trading System, capped emissions from stationary structures were 29% lower in 2018 than when the program started in 2005. Additionally, cap-and-trade programs offer flexibility, allowing firms to pursue the least costly abatement method.
However, critics argue that caps may be set too high, providing an excuse for companies to delay investing in cleaner alternatives. Cap-and-trade programs can also lead to increased prices for oil, coal, and natural gas, impacting the economy negatively. Furthermore, unlike taxes and subsidies with fixed costs, cap-and-trade programs create a market subject to market forces, resulting in fluctuating permit prices.
Overall, cap-and-trade programs are a market-based approach to reducing pollution that provides economic incentives for companies to innovate and invest in cleaner technologies. While there are advantages to this approach, there are also potential drawbacks that need to be considered when implementing such programs.

Emissions taxes
Carbon taxes are designed to reduce greenhouse gas emissions by increasing the prices of the fossil fuels that emit them when burned. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. A carbon tax is a form of pollution tax and differs from a cap-and-trade program in that it provides a higher level of certainty about cost, but not about the level of emission reduction to be achieved (cap and trade does the inverse). Taxes on greenhouse gases come in two broad forms: an emissions tax, which is based on the quantity an entity produces; and a tax on goods or services that are generally greenhouse gas-intensive, such as a carbon tax on gasoline.
While emissions taxes can be effective in reducing emissions, they can also have some negative impacts on society. In particular, while the goal of market-based policies is to add costs to polluters, taxes can end up hurting consumers instead, especially low- and middle-income communities. This is because lower-income households spend a larger share of their income on energy than higher-income households. As a result, a price on carbon that increases energy costs can have a greater impact on these households. To address this issue, policymakers can redistribute the revenue generated from carbon taxes to low-income groups through various fiscal means.
There are also challenges in forecasting the resulting level of emissions reduction from a specific tax rate. Building in review and opportunity for adjustment can help, but it also reduces the value of price certainty. In addition, carbon taxes may be too conservative, making only a small dent in overall emissions. To make carbon taxes more effective, tax levels would need to reach US$100-200 per ton of CO2 equivalent in the coming decades.

Economic incentive policies
There are two broad types of economic incentive policies: command-and-control and market-based solutions. Command-and-control policies rely on government policymaking to set emission limits or enforce the adoption of specific technologies, such as smoke scrubbers. While these policies have their uses, they are often inflexible for businesses and do not promote innovation. Market-based policies, on the other hand, provide continuous monetary and near-monetary inducements to reduce pollution.
Emissions taxes, for example, introduce a per-unit tax on pollution, creating business costs that should incentivize lower pollution levels. Carbon taxes, also known as carbon pricing, charge polluters for each ton of carbon emitted. These taxes have the added benefit of raising revenue for governments, which can be used to subsidize clean energy or reduce taxes in other markets. However, emissions taxes can negatively impact society, particularly low- and middle-income communities.
Cap-and-trade programs are another successful example of economic incentive policies. These programs predetermine the level of pollution allowed and economically encourage businesses to innovate and participate in the permit market. The Montreal Protocol, which reduced ozone-depleting substances, and the Clean Air Act, which reduced acid rain, are notable implementations of cap-and-trade programs. However, these programs may be less preferable for industries where pollution abatement is costly.
Hybrid approaches that combine command-and-control and market-based incentive policies are also gaining traction. These approaches offer certainty in emission standards while providing flexibility in the abatement methods. However, they may not always be the most economically efficient option, as the level of abatement or the cost of the policy may be higher than with a pure market-based incentive approach.

Frequently asked questions
A pollution rights market is where the state creates and sells licenses that allow firms to discharge a certain amount of pollution. If the state later decides to reduce overall pollution levels, they can simply buy back the licenses. This is considered one of the most successful ways of controlling pollution.
The Clean Air Society of Australia and New Zealand (CASANZ), Clean Air in London, Clean Air Fund, and Clean Air Task Force (CATF) are some examples of non-profit organizations that aim to reduce air pollution, protect public health, and address climate change.
Markets can help reduce pollution by incorporating incentives to reduce costs. For example, the creation of markets for trading pollution rights or trading emissions credits can bring down the cost of reducing emissions.
Driving less, using public transportation, biking, carpooling, using electric vehicles, and keeping your car well-maintained are some ways to reduce air pollution. Additionally, individuals can support organizations working to improve air quality through donations or volunteering.
Governments can implement direct or indirect controls to regulate pollution. Direct controls involve banning specific pollution activities or agents, while indirect controls use systems of incentives to discourage pollution. Governments can also establish partnerships with local governments, tribal governments, and environmental professionals to implement and enforce pollution reduction programs.
