Air pollution is a pressing issue that has been linked to approximately 6.7 million premature deaths annually. It is caused by a range of factors, including energy use, mass production, and high-carbon activities like air travel. To combat this, governments and organizations worldwide have implemented various measures to reduce air pollution and mitigate its harmful effects. For instance, the US established the Clean Air Act, which aims to regulate emissions from different sources and set air quality standards. The EPA has also taken steps to reduce emissions from aircraft and industrial facilities, while encouraging the deployment of clean technologies. The EU's Zero Pollution Plan, under the European Green Deal, has set goals to reduce air pollution by 2050, with a focus on cutting premature deaths and protecting ecosystems. At the individual level, people are encouraged to use electric vehicles, improve energy efficiency, and reduce car usage to lower their carbon footprint and contribute to cleaner air.

The US has phased out ozone-depleting substances
The United States has taken significant steps to address air pollution by phasing out ozone-depleting substances (ODS) that were identified as "most damaging" to the ozone layer. This action was taken in accordance with the Clean Air Act and the Montreal Protocol, an international agreement aimed at protecting the Earth's protective ozone shield.
The Clean Air Act, enacted in 1970, is a federal law that empowers the Environmental Protection Agency (EPA) to establish and enforce air quality standards. The Act has been instrumental in reducing levels of common pollutants such as particles, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The EPA has also taken steps to limit emissions from aircraft, with a focus on reducing greenhouse gas emissions that contribute to climate change.
Under the Montreal Protocol, the United States has phased out the production and import of most ODS, including Class I substances such as chlorofluorocarbons (CFCs) and halons, which have a higher ozone depletion potential. This phase-out occurred faster than predicted and at a lower cost, demonstrating the country's commitment to protecting the environment and public health. The EPA's studies have shown that investments in ozone layer protection yield significant societal health benefits, far outweighing the costs.
The phase-out of these substances has had a positive impact on reducing interstate air pollution. For example, the creation of a nitrogen oxides (NOx) Budget Program and the implementation of the "NOx SIP Call" Rule significantly improved ozone levels across the eastern United States. Additionally, the EPA's acid rain program, motor vehicle rules, and diesel sulfur rules have dramatically cut sulfur dioxide and nitrogen oxide emissions, improving visibility and air quality in national parks.
Furthermore, the United States has encouraged the adoption of alternatives to ODS. Hydrofluorocarbons (HFCs), for instance, were introduced as non-ozone-depleting substitutes to support the phase-out of CFCs and hydrochlorofluorocarbons (HCFCs). However, while HFCs are now common in air conditioners, refrigerators, and aerosols, their emissions are growing at an alarming rate. As a result, the Parties to the Montreal Protocol agreed to phase down HFCs by the late 2040s, recognizing the urgent need to address their impact on the climate system.

The Clean Air Act has lowered common pollutants
The Clean Air Act (CAA) is a federal law that helps regulate emissions from different sources. The Act was first implemented in 1970 and has been amended several times since then, with the most recent amendment in 2022. The Clean Air Act has been successful in lowering common pollutants and improving air quality in the United States.
One of the main goals of the Clean Air Act is to reduce air pollution and protect public health. The Act has helped lower the levels of six common pollutants: particles, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide. Between 1970 and 2020, the combined emissions of these six pollutants dropped by 78%. The EPA has also taken steps to limit emissions from aircraft, as well as new industrial and power plant facilities, which has further contributed to the reduction of common pollutants.
The Clean Air Act has also led to significant health benefits for Americans. A 1997 EPA report concluded that in 1990 alone, pollution reductions under the Act prevented 205,000 early deaths, 10.4 million lost IQ points in children due to lead exposure, and millions of other cases of health effects. Additionally, actions to protect the stratospheric ozone layer are expected to save millions of American lives from skin cancer between 1990 and 2165.
The Clean Air Act has also had positive economic impacts. Cleaner air means fewer air-pollution-related illnesses, resulting in reduced medical treatment costs and lower absenteeism among American workers. The EPA estimates that for every dollar spent on reducing pollution, Americans receive $3-9 in health benefits, with the benefits far outweighing the costs.
The Clean Air Act has been successful in lowering common pollutants and improving air quality in the United States. Through the implementation of emission standards, technology innovations, and health-based air quality standards, the Act has reduced the levels of key air pollutants and improved the health and welfare of Americans.

The EU's Zero Pollution Plan aims to reduce air pollution by 2050
The EU's Zero Pollution Action Plan is a comprehensive strategy aimed at reducing air, water, and soil pollution to levels no longer considered harmful to health, natural ecosystems, and biodiversity by 2050. The plan seeks to strengthen the EU's green, digital, and economic leadership while creating a healthier and more socially just Europe and planet.
The plan includes key targets for 2030 to accelerate the reduction of pollution at its source. One of the critical aspects is the Chemical Strategy for Sustainability, aiming to better protect citizens and the environment from hazardous chemicals. The EU is taking decisive action to address pollution from large industrial installations, ensuring alignment with climate, energy, and circular economy policies. The Industrial Emissions Directive (IED) has played a significant role in reducing air pollution from concerned installations by up to 75% by 2017. However, the EU recognised the need for stronger measures, and from 2024, a more robust IED will be implemented, granting more rights to citizens and covering a broader range of industrial and agricultural activities.
The Zero Pollution Action Plan also sets stricter limits and target values for several pollutants by 2030, including particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), and sulphur dioxide (SO2). The annual limit values for PM2.5 and NO2, the two pollutants with the most significant impact on human health, will be more than halved compared to current rules. Additionally, there will be an increase in air quality sampling points in cities, ensuring more accurate monitoring and reporting on pollution levels.
To achieve its goals, the plan provides a framework for mainstreaming pollution prevention across relevant EU policies and enhancing the implementation of relevant EU legislation. It also identifies possible gaps in existing measures and aims to address them. The EU is guiding industrial investments to transform Europe's economy into a cleaner, carbon-neutral, circular, and competitive one. Companies are required to develop transformation plans outlining their path towards decarbonisation, zero pollution, and a circular economy, utilising the best available techniques to minimise emissions.
The EU's Zero Pollution Action Plan is a bold initiative that addresses the urgent need to reduce air pollution and its detrimental effects on human health and the environment. By setting ambitious targets, strengthening legislation, and promoting sustainable practices, the EU is taking a leading role in the global effort to create a healthier and more sustainable future for its citizens and the planet.

California has banned the purchase of gasoline-powered vehicles from 2035
Air pollution has been a growing problem in the United States, with high levels of soil, dust, allergens, and gasoline becoming prevalent. It is estimated that around 7 million people die annually as a result of harmful toxins emitted by air pollution. The United States has attempted to improve its air quality through various measures, such as the Clean Air Act, which has helped reduce interstate air pollution and cut down on toxic emissions from mobile and industrial sources. The Act has also encouraged the deployment of clean technologies and innovations that reduce emissions and control costs.
One significant effort to combat air pollution in California, the country's most populous state, is the ban on the purchase of new gasoline-powered vehicles from 2035 onwards. This move is a landmark step in California's battle against climate change and air pollution. The ban will not prevent people from owning, driving, or reselling conventional gasoline-powered vehicles. Instead, it will incentivize the adoption of electric vehicles (EVs) and accelerate the production of cleaner alternatives.
The California Air Resources Board (CARB) has been instrumental in driving this initiative, with the goal of achieving a 50% reduction in pollution from cars and light trucks by 2040. The Advanced Clean Cars II rule, implemented by CARB, establishes a timeline for the transition to zero-emission vehicles. Beginning in 2026, automakers will be required to increase the sales of zero-emission vehicles, with a target of 35% of new vehicle sales, rising to 68% by 2030. By 2035, only electric or plug-in electric hybrid vehicles will be permitted for new car sales in California.
This ban on gasoline-powered vehicles in California is made possible by a federal waiver under the Clean Air Act, which allows the state to adopt stronger fuel economy standards and regulate vehicle emissions more strictly than federal regulations. California has a history of pioneering emissions standards, establishing the nation's first tailpipe emissions standards in 1966. The state's ability to set its own standards has spurred innovations in emission reduction technology, such as catalytic converters and "check engine" lights.
While the ban on gasoline-powered vehicles in California is a bold step towards reducing air pollution, it also faces challenges and opposition. There are concerns about the infrastructure and resources needed to support the transition to electric vehicles, including the availability of charging stations and materials for battery production. Additionally, some critics argue that the ban could limit consumer choice and that the timeline may be challenging for both consumers and automakers to meet. Despite these challenges, California's ban on gasoline-powered vehicles from 2035 onwards represents a significant commitment to improving air quality and mitigating the impacts of climate change.
