Governments around the world are tasked with tackling the issue of pollution, which has wide-ranging impacts on public health and the environment. While there is no one-size-fits-all solution, a range of strategies can be employed to address this complex problem. This includes implementing regulations and laws, such as the Clean Air Act, which aim to reduce emissions and improve air quality. Governments can also provide incentives, such as subsidies, to encourage the use of less polluting technologies and promote behavioural changes through education and awareness campaigns. In addition, governments can play a crucial role in facilitating cooperation between federal departments, states, and local authorities, as well as providing financial assistance and grants to support pollution reduction initiatives.

Implement pollution taxes and subsidies
Governments have a variety of tools at their disposal to control pollution, one of which is the implementation of pollution taxes and subsidies. This approach uses economic incentives to encourage firms and individuals to reduce pollution and promote environmentally friendly activities.
One way to do this is to tax emissions from point sources, such as stationary sources like industrial facilities, while providing subsidies for non-point source controls. This could include subsidies for activities such as brownfield development after hazardous substance contamination, agricultural grants for erosion control, and grants for land conservation. Subsidies can also be used to encourage market entry for environmentally friendly products, such as through deposit-refund systems. For example, the government can provide grants and incentives for the adoption of electric vehicles, as well as promote the development and use of clean technologies.
Another form of pollution tax is a carbon tax on fossil fuels, which can improve the competitiveness of renewable energy sources and nuclear energy. By increasing the price of carbon-intensive fuels, carbon taxes can encourage energy conservation, the adoption of energy-efficient appliances and processes, and a transition to low-carbon energy sources. This approach is consistent with the “polluter pays” principle, where the costs of pollution are internalized by the polluter rather than externalized to society.
The revenue generated from pollution taxes can be used to enhance economic efficiency and address social inequalities. This is known as the double dividend hypothesis, which suggests that environmental tax revenues can be used to finance reductions in pre-existing taxes, particularly distortionary taxes on labor or investment that may impair economic welfare. This approach can potentially lead to both environmental and economic gains, as the revenue generated from pollution taxes can be used to improve government services and reduce economic distortions from other tax systems.
In addition to taxes, governments can implement differential pricing for resources used by mobile sources of pollution, such as higher tolls on roads during rush hour or greater subsidies for public transportation. These price-based instruments can be complemented by quantity-based instruments, such as marketable permits that define trading ratios to ensure emission standards are met. Permit systems can also be designed to favor new firms and prevent existing firms from having too much control over prices.

Create regulations and permits
One of the most important roles of governments in tackling pollution is to create and enforce regulations and permits. Regulations and permits can be used to control both air and water pollution, with the former being a more prominent issue in cities and urban areas.
Air Pollution Permits and Regulations
Federal regulations require that major sources of air pollutant emissions obtain "operating permits". These permits consolidate all air pollution control requirements into a single document, covering all aspects of the source's air pollution activities. The Clean Air Act Amendments of 1990 established the air permitting program for the federal government, with permits issued by state and local authorities, as well as the EPA in certain cases. These permits are legally enforceable and ensure compliance with emission limits and other requirements.
The EPA also issues guidance and technical assistance to states to help them develop plans to reduce air pollution and comply with the Clean Air Act. This includes setting national emissions standards for new stationary sources of pollution, such as industrial and commercial facilities.
Water Pollution Permits and Regulations
The EPA's National Pollutant Discharge Elimination System Permit Program regulates facility discharges into US waters. The program issues permits to ensure that discharges meet federal and state water quality standards. The EPA also regulates the discharge of dredged or fill material into US waters, including certain wetlands, to control water pollution.
Land Pollution Permits and Regulations
Land pollution control permits are required for managing certain types of waste. Wastes are categorized as either nonspecial or special, with the latter being more harmful and subject to stricter regulations. Special waste includes potentially infectious medical waste, industrial process waste, pollution control waste, and hazardous waste.
Local Regulations and Incentives
In addition to federal and state regulations, local governments can play a crucial role in pollution control by passing local ordinances, creating incentives for beneficial behaviors, and promoting and educating residents on best practices. For example, the Minnesota Pollution Control Agency provides education, guidance, and incentives for reducing air pollution from vehicles, construction equipment, and other sources.

Provide incentives for cleaner alternatives
Economic incentives have proven to be an effective tool for governments to encourage cleaner alternatives and control pollution. Market-based approaches or incentives provide continuous inducements, including monetary incentives, to encourage polluting entities to reduce the release of harmful pollutants. These incentives create a continuous incentive for the private sector to incorporate pollution abatement into production or consumption decisions and to innovate in a way that continually searches for the least costly method of abatement.
One example of such an incentive is the trading system, where companies with extra pollution reductions can trade or sell emission credits to other companies, typically those facing higher costs to control pollution. This system provides companies with flexibility in reducing emissions and minimizing compliance costs.
Another example is the use of information disclosure programs, which aim to influence firm behavior by disseminating information on production processes, labor standards, and pollution levels to government agencies or the public. By making various stakeholders a part of the regulatory process, all parties are incentivized to practice socially responsible behavior.
In addition to these, governments can also promote voluntary programs that assist and reward actions to reduce energy use and limit pollution. For instance, the Energy Star, Waste Wise, and XL programs in the United States encourage the adoption of cleaner alternatives.
At the local level, governments can create incentives for beneficial behaviors and promote and educate residents on best practices. For instance, providing incentives for the use of electric or hand-powered lawn equipment instead of gas-powered engines, which often lack pollution control devices, can significantly reduce pollution.
By utilizing these incentive-based approaches, governments can effectively encourage the adoption of cleaner alternatives and make substantial progress in controlling pollution.

Develop and enforce state plans
The Environmental Protection Agency (EPA) is a crucial partner for states in developing and enforcing plans to control pollution. The EPA provides guidance, technical assistance, and financial support to states as they create and implement their pollution control strategies. For instance, the EPA issues national emissions standards for new stationary sources, such as power plants, industrial boilers, and cement manufacturing facilities, and assists states in establishing state-level standards for toxic air emissions from various sources.
The EPA also plays a significant role in ensuring that state plans comply with federal legislation, such as the Clean Air Act (CAA) and the Clean Water Act. Under the CAA, the EPA sets goals for reducing carbon and greenhouse gas emissions, and states determine how they will achieve those goals. The EPA reviews state plans and provides feedback to ensure alignment with the Act. Similarly, the EPA works with states to meet standards for common pollutants, issuing federal emissions standards for motor vehicles, non-road engines, and industrial equipment.
In addition to providing guidance and standards, the EPA offers financial support for pollution control efforts. The EPA can provide grants to state pollution control agencies and has the authority to establish a pollution control revolving fund to assist states in implementing management and conservation plans. The EPA also recognizes the role of tribal governments in implementing the Clean Air Act, providing training, grants, and technical support to increase their capacity to develop and manage air quality programs.
State and local governments play a crucial role in developing and enforcing plans to control pollution within their jurisdictions. They can pass local ordinances, create incentives for businesses and residents to adopt more sustainable practices, and promote education and awareness about pollution prevention. For example, in California, local air pollution districts work with the state to produce air quality plans, and states can adopt programs that delegate authority to enforce toxic emissions standards to local agencies.
Overall, effective pollution control requires collaboration between federal, state, and local governments, with the EPA providing guidance, technical assistance, and financial support to states and local agencies as they develop and enforce their plans to address pollution.

Encourage behaviour change
Behaviour change is key to improving air quality, and governments can play a significant role in encouraging this. Firstly, governments should focus on raising awareness and educating citizens about the impact of their actions on the environment. This includes providing tailored information about health issues related to pollution, such as air pollution and asthma, which can motivate people to take action. For example, parents and teachers can work with schools to implement no-idling policies for buses and trucks, as their exhaust contributes significantly to unhealthy air quality.
Secondly, governments can incentivize citizens to make sustainable choices. This can include providing subsidies for electric vehicles, creating scrappage schemes for older polluting vehicles, and promoting active travel, such as walking and cycling, or the use of public transportation. In addition, governments can offer incentives for businesses to reduce their environmental impact, such as through grants and technical support, as demonstrated by the US EPA's Office of Air and Radiation, which works with tribal governments to improve air quality.
Thirdly, governments should focus on community engagement and collective action. This includes encouraging the development of local pressure groups and providing platforms for community discussions. For instance, the GreenStep Cities program in Minnesota involves local governments creating incentives for beneficial behaviours and promoting and educating residents on best practices for sustainability.
Finally, governments can implement regulations and standards to reduce emissions and improve air quality. This includes enforcing plans to reduce pollutants in protected areas, such as national parks, and requiring major stationary sources of emissions to obtain permits and comply with federal standards, as seen in the Clean Air Act in the US. These regulations ensure that facilities control their toxic emissions and contribute to improved air quality.
