Reduce emissions from cars
Air pollution is a serious environmental health problem that affects people in low-, middle-, and high-income countries. It is caused by various sources, including transportation, industry, power generation, and municipal waste management. One significant contributor to air pollution is motor vehicles, particularly those burning gasoline and diesel fuel, which create harmful byproducts such as nitrogen dioxide, carbon monoxide, hydrocarbons, benzene, and formaldehyde.
To reduce emissions from cars and improve air quality, individuals can take several measures. Firstly, when purchasing a new car, it is essential to consider fuel-efficient vehicles with low greenhouse gas emissions. Electric vehicles, for example, produce no exhaust emissions and can be an excellent option for those with access to charging facilities. Additionally, maintaining proper tire inflation can make your vehicle more fuel-efficient, as underinflated tires can increase fuel consumption and emissions.
Another way to reduce emissions is to limit unnecessary idling. Modern vehicles do not require prolonged warming up in cold weather, so turning off the engine when the car is not in motion can help reduce pollution and fuel waste. Observing speed limits and accelerating gradually also contribute to lower emissions. Getting a vehicle moving from a complete stop uses the most energy, so easing up on the accelerator can make a difference.
While individual actions are essential, collective efforts and policy changes are also necessary to address air pollution effectively. Local governments and authorities can implement clean air zones, improve road layouts and traffic flow, promote active transportation like cycling and walking, and make public transportation more attractive and accessible. These measures can help reduce car emissions and encourage more sustainable modes of transportation.
Furthermore, supporting initiatives for cleaner transportation and energy-efficient technologies is crucial. This includes investing in commercial-grade landscaping machinery with advanced emissions reduction technologies and encouraging businesses and organizations to adopt more sustainable practices through programs like the Small Business Environmental Assistance Program. By combining individual actions with collective efforts and policy changes, we can make significant progress in reducing emissions from cars and improving air quality.

Phase out fossil fuels
Phasing out fossil fuels is a crucial step in preventing air pollution and mitigating the adverse effects of climate change. Fossil fuels, such as coal, oil, and natural gas, are major contributors to air pollution and greenhouse gas emissions. Here are some key steps and strategies to phase out fossil fuels and transition to a cleaner and more sustainable energy future:
Policy and Government Action:
Governments and policymakers play a pivotal role in phasing out fossil fuels. This includes setting clear targets and timelines for the phase-out of unabated fossil fuels, such as the commitment to reach 100% decarbonized power systems by 2035 in advanced economies and by 2040 for other countries, as outlined by the We Mean Business Coalition. Governments should also halt any new oil and gas production licenses, leases, or contracts, and redirect financial flows away from fossil fuels, including reforming fossil fuel subsidies.
Energy Transition:
The transition to cleaner and renewable energy sources is essential. This involves establishing a clear end date for oil, gas, and coal production and use, and implementing managed schemes to gradually remove fossil fuels from energy systems. This can be done by encouraging the use of less emissions-intensive fuels, such as electricity, and requiring industrial sites to adopt emissions plans to promote energy efficiency and the adoption of low-emission fuels.
Addressing Barriers:
Removing barriers to the phase-out of fossil fuels is crucial. For example, changes to the Resource Management Act (RMA) in New Zealand will allow local authorities to consider the effects of greenhouse gas emissions on climate change when making decisions, thereby facilitating the transition to a low-emissions economy. Similarly, removing barriers at the local level can empower councils and municipalities to make informed decisions about reducing air pollution.
Incentivizing Sustainable Behaviors:
Incentivizing individuals, businesses, and communities to adopt sustainable practices can accelerate the phase-out of fossil fuels. This can include providing incentives for behaviors that reduce waste in energy systems, promoting the use of electric or hand-powered equipment over gas-powered engines, and supporting initiatives like the Small Business Environmental Assistance Program, which helps businesses reduce waste and emissions.
International Cooperation:
Addressing climate change and phasing out fossil fuels require global collaboration. Wealthier countries, as historic emitters, have a responsibility to lead the way. This includes supporting countries in the Global South in diversifying their economies and developing net-zero pathways through finance and capacity-building initiatives. International agreements, such as the Paris Agreement, provide a framework for countries to work together towards common goals.
By following these steps and strategies, the phase-out of fossil fuels can be achieved, contributing significantly to air pollution prevention and the mitigation of climate change impacts.

Promote sustainable agriculture
Agriculture is a significant source of air pollution, contributing to around 93% of ammonia emissions in the EU, for instance. These emissions are linked to poor manure management and the use of synthetic nitrogen fertilisers. Therefore, promoting sustainable agriculture is crucial in the fight against air pollution.
One way to promote sustainable agriculture is by encouraging farmers to adopt improved nutrient management techniques. This involves applying the right amount of nutrients (fertiliser and manure) at the appropriate time of year, using the correct method, and placing them in the right location. This helps prevent excess nutrients from entering the water and air, which can lead to eutrophication of water bodies and the release of harmful ammonia into the atmosphere.
Another method is the implementation of conservation practices. Conservation drainage practices, such as subsurface tile drainage, help manage water movement through soils. Conservation tillage, which reduces the frequency and intensity of tilling, improves soil health, reduces erosion, and decreases the likelihood of nutrients reaching waterways through runoff. Additionally, keeping livestock and their waste away from streams helps prevent nitrogen and phosphorus from entering the water, protecting water quality and stream banks.
Farmers can also contribute by planting cover crops or perennial species to prevent bare ground on farm fields. This helps avoid soil erosion and nutrient loss during vulnerable periods. Planting field buffers, such as trees, shrubs, and grasses, along field edges, especially those bordering water bodies, acts as a natural filter, absorbing and trapping nutrients before they reach water bodies.
To support these efforts, governments and organisations play a vital role. The Common Agricultural Policy (CAP) in the EU, for instance, promotes sustainable agricultural systems, providing incentives for farmers who preserve natural resources and contribute to environmental goals. The Climate and Clean Air Coalition (CCAC) also works to reduce methane and black carbon emissions from agriculture, offering solutions such as improved manure management and "no-burn" alternatives to open crop residue burning.

Implement carbon tax systems
Air pollution is a critical global health issue that demands collective action to control emissions and reduce health risks. While individual actions, such as limiting backyard fires and switching to electric equipment, can help reduce local pollution sources, implementing carbon tax systems is a powerful tool for addressing air pollution on a broader scale.
A carbon tax is a market-based approach that puts a price on carbon emissions, typically charged per ton of greenhouse gas emissions. This pricing mechanism aims to internalize the external costs of pollution and climate damage, incentivizing emitters, including businesses and consumers, to reduce their carbon footprint. The tax can be levied at any point in the energy supply chain, with fossil fuels, coal, oil products, and natural gas being common targets due to their carbon content.
Several countries and local governments have already implemented carbon tax programs. For example, British Columbia has had a carbon tax since 2008, and South Africa became the first African country to adopt one in 2019. In the United States, cities like Boulder, Colorado, have taken the initiative, and interest in a nationwide carbon tax is growing.
The revenue generated from carbon taxes can be used in various ways. Some proposals suggest returning it to consumers in the form of dividends or using it to reduce taxes on productive activities. Alternatively, the revenue can be reinvested in climate initiatives, such as advancing low-carbon technologies, building resilience, or funding infrastructure improvements.
While the economic implications of carbon taxation are well understood, political viability remains a challenge. Carbon taxes can disproportionately impact lower-income groups, and careful policy design is necessary to address these concerns. Additionally, carbon tax systems must be implemented alongside other measures, such as incentives for clean energy adoption and education on sustainable practices, to create a comprehensive approach to air pollution prevention.
