Governments around the world are taking various steps to combat the issue of pollution, which contributes to the death of millions of people annually. For instance, the US Environmental Protection Agency (EPA) works with federal, state, and local governments to implement the Clean Air Act and reduce air pollution. The EPA provides guidance, technical assistance, and grants to state and tribal governments to develop and enforce toxic emissions standards and air quality plans. In California, the state government sets its own emissions limits and creates policies to address the state's unique air quality challenges. Similarly, the UK government's research has led to initiatives such as deterring polluting vehicles from city centres and implementing scrappage schemes for older vehicles to reduce nitrogen dioxide pollution. These efforts demonstrate the commitment of governments to tackle pollution and protect public health and the environment.

What You'll Learn
The Clean Air Act
One of the goals of the Act was to set and achieve NAAQS in every state by 1975 to address the public health and welfare risks posed by certain widespread air pollutants. The setting of these pollutant standards was coupled with directing the states to develop state implementation plans (SIPs), applicable to appropriate industrial sources in the state, in order to achieve these standards. The Act was amended in 1977 and 1990 primarily to set new goals (dates) for achieving attainment of NAAQS since many areas of the country had failed to meet the deadlines.
Under the CAA, the EPA issues guidance on state planning and required controls and reviews state plans to ensure they comply with the Act. The EPA also establishes health-based national air quality standards to protect people with an "adequate margin of safety". States are responsible for developing enforceable state implementation plans to meet these standards. In some states, local air pollution districts work with the state to produce air quality plans. Each state plan must also prohibit emissions that significantly contribute to air quality problems in a downwind state.
The CAA also requires major stationary sources and certain other sources subject to federal standards to obtain operating permits. In most areas, state or local air agencies issue the permits. Elsewhere, the EPA or a tribal government is the permitting authority. Tribal governments can play an important role in implementing the CAA in their areas. The EPA's Office of Air and Radiation (OAR) works closely with tribal governments and tribal environmental professionals to increase their capacity to develop and manage their air quality programs by providing training, grants, and technical support.

Pollution Prevention Act
The Pollution Prevention Act of 1990 (PPA) is a United States federal law that establishes a national policy to promote the prevention of pollution or reduction at pollution sources whenever possible. The Act focuses on reducing the amount of pollution through cost-effective changes in production, operation, and raw materials use.
The PPA asserts that pollution should be prevented or reduced at the source whenever feasible. When pollution cannot be prevented, it should be recycled in an environmentally safe manner. If it cannot be recycled, it should be treated in an environmentally safe way, and disposal or release into the environment should be a last resort, conducted safely.
The Environmental Protection Agency (EPA) is tasked with implementing this policy. The EPA's Office of Pollution Prevention and Toxics (OPPT) manages programs under the Toxic Substances Control Act and the PPA. The EPA evaluates new and existing chemicals and their risks and works to prevent or reduce pollution before it enters the environment. The EPA also provides technical assistance to industry and government agencies and enforces regulations.
The PPA encourages cooperation among federal departments, states, and local governments to prevent and control air pollution. The EPA is mandated to establish a national research and development program for pollution prevention and control. The Act also allows the EPA to make grants to pollution prevention and control agencies and to establish record-keeping, inspections, and monitoring for facilities that emit pollutants.
The PPA also addresses water pollution, mandating the EPA to work with federal, state, and local agencies and industries to develop programs to prevent, reduce, or eliminate the pollution of navigable, ground, surface, and underground waters, and improve their sanitary conditions.

Federal, state and local government cooperation
The US government's ability to marshal vast resources, coordinate countrywide approaches, and cooperate with other countries remains an indispensable tool in the fight against climate change. The federal government can coordinate and fund measures, but state and local governments also play a critical role in helping or hindering the fight against climate change.
The Clean Air Act calls for state, local, federal, and tribal governments to implement the Act in partnership to reduce pollution. The Environmental Protection Agency (EPA) is mandated to establish a national research and development program for the prevention and control of air pollution. The EPA also provides guidance and technical assistance to assist state planning, issues national emissions standards for new stationary sources, and reviews state plans to ensure compliance with the Act. States are responsible for developing enforceable state implementation plans to meet the standards. In some states, like California, local air pollution districts work with the state to produce air quality plans.
Congress has also established a federal acid rain program to cut emissions from power plants that cross state lines. The law required the EPA to issue implementing rules, track the trading of emissions allowances, and monitor compliance. Congress charged the EPA with phasing out the production of ozone-depleting chemicals and ensuring their proper recycling, disposal, and labeling.
The federal government often dedicates a pot of money toward accomplishing a general goal under certain parameters. States and local governments can apply for that money in the form of grants by proposing ways to use the funds to help achieve the federal government's goals in their jurisdictions. For example, the federal government offers around $5 billion in Climate Pollution Reduction Grants. If states and local governments commit to developing and implementing plans to reduce emissions and other air pollution, they can access that money to help fund their mitigation efforts.
Federal agencies also regulate energy transmission across state lines, including the construction of interstate power lines or oil and gas pipelines and the sale of electricity between companies in different states. Environmental regulations can also influence how utility companies operate power plants. Federal air pollution standards, for example, can limit how much of a certain pollutant power plants are allowed to emit.

Transboundary pollution agreements
One of the most prominent transboundary pollution agreements is the 1979 Convention on Long-Range Transboundary Air Pollution (LRTAP). This agreement created a regional framework applicable to Europe, North America, Russia, and former East Bloc countries to reduce transboundary air pollution and advance the understanding of air pollution science. LRTAP has been highly successful, leading to a significant decline in air pollution emissions, particularly sulfur emissions, and facilitating economic growth decoupled from air pollution trends. The convention has 51 parties and eight protocols, with most protocols addressing specific pollutants.
The Geneva Convention on Long-Range Transboundary Air Pollution is another significant agreement. Under this convention, eight separate protocols have been developed to address various aspects of transboundary air pollution. The protocols include the 1984 EMEP Protocol, which established a cost-sharing mechanism for the cooperative programme monitoring and evaluating long-range air pollution transmission in Europe. The 1985 Helsinki Protocol focused on reducing sulphur emissions or their transboundary fluxes by at least 30% compared to 1980 levels. The 1988 Sofia Protocol addressed the control of emissions of nitrogen oxides (NOx) and their transboundary fluxes, aiming to freeze NOx emissions at 1987 levels and adopt an effects-based approach to further reduce emissions of nitrogen compounds.
The 1999 Gothenburg Protocol, which is under the LRTAP convention, is the first international agreement to address black carbon. It aims to further reduce emissions of harmful air pollutants and address particulate matter. The Gothenburg Protocol, along with the Protocol on Heavy Metals, underwent amendments in 2012 to introduce more flexibility in implementing obligations without sacrificing effectiveness. These amendments were ratified by the United States in 2015 and 2017, respectively.
Overall, these transboundary pollution agreements provide a framework for international cooperation and the adoption of cost-effective strategies to mitigate the negative impacts of air pollution on a broad regional scale.

Scrappage schemes for polluting vehicles
The UK's scrappage scheme was initially introduced to help the motor industry through the recession that followed the 2008 financial crash. The scheme gave vehicle owners £2,000 (co-funded by the Government and the car industry) if they scrapped their old vehicle and bought a new one. The number of new cars sold increased during the scheme, with figures for February 2010 26% higher than the previous year. The average emissions of new cars sold during the scheme dropped by 5.4% from the year before.
The scrappage scheme has been extended several times and, as of 2023, is still in place across the UK. While it has been successful in encouraging people to buy new cars, there has been criticism that it does not limit the purchase of economical cars. There are also concerns about the environmental costs associated with the production of new vehicles.
In addition to the scrappage scheme, the UK government has implemented other measures to reduce pollution from vehicles. These include the introduction of ultra-low emissions zones (ULEZ) in London and other cities, rising VED rates for cars with higher CO2 emissions, and the ban on the sale of new petrol and diesel cars. These measures work together to incentivize people to switch to alternative-fuel cars and reduce the number of high-polluting vehicles on the road.
