Governments around the world are taking action to combat the harmful effects of pollution, particularly air pollution, which has been linked to a range of health issues, from asthma in children to heart disease and reduced life expectancy. Strategies to reduce pollution vary and often involve multiple sectors of society, including industry, transport, and agriculture. For example, the UK government has launched a Clean Air Strategy that aims to reduce emissions from a wide range of sources, while also providing support for farmers to adopt low-emission farming techniques. Similarly, the Minnesota Pollution Control Agency offers education, guidance, and incentives to reduce air pollution from vehicles, encouraging carpooling, biking, and the use of electric vehicles. Additionally, the US Environmental Protection Agency promotes pollution prevention practices, or P2, which focus on reducing or eliminating waste at the source by modifying production processes, using less toxic substances, and improving conservation techniques. These initiatives not only protect the environment but also strengthen economic growth and reduce the financial costs associated with waste management.

Provide support and incentives for farmers to adopt low-emission farming techniques
Agriculture is a significant contributor to global emissions, with the global agrifood system emitting one-third of all emissions. As such, governments must provide support and incentives for farmers to adopt low-emission farming techniques.
One way to do this is through increased government co-financing for lower-emission agricultural techniques. For example, the World Bank has committed almost $3 billion annually to climate-smart agriculture (CSA), which includes the adoption of climate-resilient crop varieties, conservation agriculture techniques, agroforestry, precision farming, water management strategies, and improved livestock management. Governments can also provide grants and loan guarantees to help farmers access renewable energy systems and energy efficiency improvements, such as through the USDA's Rural Energy for America Program (REAP).
In addition to financial incentives, governments can also provide regulatory incentives. For instance, making eligibility for crop insurance and other farm subsidies conditional on farmers not converting natural forest or grassland to cropland. This policy, known as the Sodsaver provision, has already been successfully implemented in the 2014 Farm Bill, cutting federal crop insurance subsidies for cropland established on sensitive lands. Similarly, introducing regulations to require farmers to use low-emission farming techniques and minimize pollution from fertilizer use can also help reduce emissions.
Furthermore, governments can support farmers in transitioning to low-emission farming techniques by providing training and advice. In the UK, for instance, the government launched a £3 million program through the Catchment Sensitive Farming (CSF) partnership to fund a team of specialists who work with farmers and landowners to provide training events, tailored advice, and support with grant applications. Governments can also accelerate research and uptake of low-emission farming techniques by implementing policies such as fertilizer efficiency standards and low-carbon fertilizer programs.
By providing a combination of financial, regulatory, and educational support, governments can effectively incentivize farmers to adopt low-emission farming techniques, helping to reduce pollution and mitigate climate change.

Implement regulations to minimise pollution from fertiliser use
Agriculture is a major source of pollution, and the use of fertilisers is a significant contributor. Nitrogen-based fertilisers, in particular, have been linked to air pollution and water pollution, as well as soil degradation. To minimise pollution from fertiliser use, governments can implement and enforce several regulations:
Regulate Fertiliser Composition and Use
Governments can mandate the composition of fertilisers, limiting the amount of nitrogen and other potentially harmful chemicals. This will help reduce the environmental impact of fertiliser use, as excess nitrogen can escape into the environment, causing air pollution and water pollution. Regulations should also be put in place to control the environmental risks caused by chemical processes used in fertiliser production, such as acid dissolution, pressure, and high temperatures.
Support Sustainable Farming Practices
Governments should provide support and incentives for farmers to adopt sustainable and low-emission farming techniques. This includes promoting the use of organic fertilisers, such as animal manure, and precision farming techniques to optimise fertiliser application and reduce waste. The USDA, for example, has increased spending on programs that train and equip farmers with practices that reduce nitrogen pollution. Governments can also collaborate with farmers, providing them with the necessary resources and expertise to implement these practices effectively.
Monitor and Control Pollutants
To protect human health and the environment, governments can mandate the installation of monitoring networks in fertiliser production plants. These networks can measure and control pollutant levels, such as sulphur oxide, ammonia, and nitrogenous by-products, which are released during the production process. Early detection of these pollutants is crucial to enable prompt action and efficient decision-making to mitigate their impact.
Collaborate with Farmers and Stakeholders
Governments should engage with farmers, state governments, conservation groups, educational institutions, and community groups to reduce nutrient pollution. This collaboration can lead to the development and implementation of best practices that balance environmental concerns with the economic challenges faced by farmers. By working together, governments, and agricultural communities can identify effective solutions that are practical and economically viable for farmers.
Prioritise Nitrogen Pollution in Environmental Policies
Nitrogen pollution has often been overlooked in environmental policies, which tend to focus on carbon dioxide reduction. Governments should prioritise addressing nitrogen pollution in their strategies to combat climate change, air pollution, water pollution, and biodiversity loss. This includes allocating resources for research and development of nitrogen-reducing technologies and practices, as well as implementing regulations that specifically target nitrogen emissions.

Encourage the use of renewable energy sources to reduce pollution from power stations
The production of electricity contributes significantly to air pollution. Governments can encourage the use of renewable energy sources to reduce pollution from power stations in several ways. Firstly, they can provide incentives for individuals and businesses to switch to renewable energy suppliers. This can be done through subsidies, grants, or tax breaks for those who choose renewable energy tariffs, making it more affordable and attractive for people to switch.
Secondly, governments can increase investment in renewable energy infrastructure. This includes funding the construction of new solar and wind farms, as well as research and development into emerging renewable technologies such as lithium-ion battery storage systems. By investing in renewable energy sources, governments can help accelerate the transition away from fossil fuels and reduce the pollution emitted by power stations.
Another way to encourage the use of renewable energy is to implement regulations and standards that promote their adoption. For example, governments can set targets for increasing the share of renewable energy in the national energy mix and provide incentives for energy companies to meet these targets. They can also introduce carbon pricing mechanisms, such as cap-and-trade systems or carbon taxes, to make fossil fuels less financially attractive compared to cleaner alternatives.
In addition to these measures, governments can lead by example by committing to power their own operations with renewable energy. This can include powering government buildings, public transportation, and infrastructure with renewable sources. By doing so, governments can demonstrate their commitment to renewable energy and encourage its wider adoption.
Finally, governments can play a crucial role in raising awareness about the benefits of renewable energy and educating the public about the impact of their energy choices. This can involve public information campaigns, educational initiatives, and partnerships with community organizations to promote renewable energy and energy conservation. By empowering individuals to make informed choices, governments can further drive the transition to cleaner energy sources and reduce pollution from power stations.

Invest in public transport, active travel, and electric vehicles to reduce transport emissions
Transport is a major source of air pollution, particularly in cities. To reduce transport emissions, governments should invest in sustainable and active travel options, as well as promote the adoption of electric vehicles.
Firstly, governments should prioritize investing in and improving public transportation systems. This includes options such as buses, trams, and trains. Encouraging people to use public transport can significantly reduce emissions, as every vehicle on the road releases an average of one pound of CO2 per mile driven, whereas public transportation reduces CO2 emissions by 45%. It is estimated that public transportation in the US saves 37 million metric tons of carbon dioxide annually.
Secondly, governments should invest in infrastructure that promotes active travel, such as walking and cycling. This can be achieved through the development of pedestrian and bicycle pathways, as well as initiatives that make these modes of transportation safer and more accessible. Moderate increases in bicycle use each year could save an estimated 6 to 14 million tons of carbon dioxide. Walking or cycling also have the added benefit of promoting healthier lifestyles for citizens.
In addition to these sustainable travel options, governments should also encourage the adoption of electric vehicles (EVs). This can be done through various incentives and initiatives. For example, providing subsidies or tax breaks for those who purchase electric cars, as well as investing in the necessary infrastructure, such as charging stations. Strong regulations and fiscal incentives, along with significant investment in infrastructure to enable low- and zero-emission vehicle operations, are crucial steps to reducing transport emissions. Governments can also set sales targets for zero-emission vehicles, providing a clear signal to the market and driving investment across the EV ecosystem, from battery manufacturers to charging infrastructure developers.
By investing in public transport, active travel, and electric vehicles, governments can play a crucial role in reducing transport emissions and improving air quality for their citizens. These initiatives will also contribute to the broader goal of creating a more sustainable future and mitigating the impacts of climate change.

Educate the public on the health risks of air pollution and ways to reduce their contribution
Education is a powerful tool to mitigate the harmful effects of air pollution. Governments and communities can work together to raise awareness about the health risks of air pollution and ways to reduce individual contributions. Here are some ways to educate the public on these important issues:
Provide Accurate and Timely Information: Governments can disseminate factual information about the health risks of air pollution, such as respiratory diseases, cardiovascular issues, cancer, and adverse effects on pregnancy. Communicating the risks clearly and promptly empowers individuals to understand the impact of air pollution on their health and motivates them to take action.
Promote Environmental Health Literacy: Environmental Health Literacy (EHL) is about understanding the link between environmental exposures and health. By educating individuals about EHL, they can make informed decisions to protect their health and reduce their contribution to air pollution. This includes understanding the causes of air pollution and how individual actions can collectively make a significant difference.
Encourage Interactive Learning: Beyond individual education, fostering interactive learning opportunities can help build skills and increase self-efficacy. This could include community workshops, group discussions, or online forums where individuals can learn from each other and share practical tips for reducing air pollution and its health impacts.
Raise Awareness Through Campaigns: Governments can launch creative and engaging campaigns to raise awareness about air pollution and health. For example, the "Spare the Air" campaign encouraged people to take action during summer months. Such campaigns can utilize various media platforms, social media, and community events to reach a wide audience.
Involve Schools and Youth Programs: Educating younger generations about air pollution and health is crucial. Programs like Real-Time Outdoor Activity Risk (ROAR) help ensure children and school officials are mindful of outdoor playtime when air quality is poor. Including educational modules about air pollution and health in school curricula can foster a sense of environmental stewardship from an early age.
By implementing these educational strategies, governments can empower individuals to make informed choices, adopt sustainable practices, and collectively contribute to reducing air pollution and mitigating its health risks.
