Poor Countries: Reducing Pollution, Improving Lives

Air pollution is a pressing issue that disproportionately affects people in low- and middle-income countries. According to the World Health Organization, 97% of cities in low- and middle-income countries do not meet the WHO air quality guidelines, compared to 49% in high-income countries. This disparity is due to various factors, including weaker laws and enforcement, less stringent vehicle emission standards, and a greater reliance on coal power.

The consequences of air pollution are dire, with approximately seven million deaths globally attributed to air pollution each year. The health impacts of air pollution include stroke, heart disease, lung cancer, chronic obstructive pulmonary disease, and respiratory infections. In addition, air pollution also affects economic productivity, exacerbates inequalities, and reduces cognitive abilities.

To reduce air pollution in poor countries, several interventions can be implemented. These include adopting cleaner methods of transportation, investing in energy-efficient power generation, and providing universal access to clean and affordable fuels. Additionally, positive incentives, such as the facilitated transfer of environmentally friendly technologies and technical skills, can help lay a strong foundation for mitigating manufacturing pollution.

It is important to recognize that the push for net-zero emissions should not unfairly burden poor countries. Instead, a balanced approach is needed, where high emitters reduce their emissions aggressively, while poor countries lower their growth rate of emissions on a credible path toward net zero.

Invest in renewable energy sources

Poor air quality disproportionately affects people in low-income countries and cities. According to the World Health Organization (WHO), 97% of cities in low- and middle-income countries do not meet the WHO air quality guidelines, compared to 49% in high-income countries.

One of the main reasons for this disparity is that governments in developing countries often do not prioritize cleaner energy sources, and renewable energy sources tend to be more expensive than cheap fossil fuels like coal.

Therefore, investing in renewable energy sources is crucial to reducing pollution in poor countries. Here are some ways to do this:

Wind Energy

Wind energy is one of the cleanest sources of energy as it does not directly affect air pollution emissions and does not require water for cooling. Wind turbines can be placed anywhere with high-speed winds, including hilltops and open water.

Solar Energy

Solar energy is another clean energy source that uses photovoltaic cells to convert sunlight into electricity. It does not produce air pollutants or contribute to greenhouse gas emissions. However, the manufacturing process of solar panels may produce some emissions.

Geothermal Energy

Geothermal energy utilizes the heat produced within the Earth. Water injected deep underground is heated by the Earth's molten interior and returns as hot water or steam, which is used to power a turbine to generate electricity. Geothermal energy produces significantly less carbon dioxide than a natural gas power plant and minimal NO2 or SO2 pollution.

Hydroelectric Power

Hydroelectric power plants use water flow, such as from rivers, to turn turbines and generate electricity. While this can disrupt river ecosystems, it is still a renewable energy source that does not produce air pollutants or contribute to global warming emissions.

Biomass

Biomass involves burning organic matter, such as wood, and is sometimes listed as a renewable energy source. However, the American Lung Association opposes biomass combustion due to the particle pollution and carcinogens released during burning. A potential alternative is pyrolysis, where biomass is heated in an anaerobic environment, producing fewer air pollutants.

Nuclear Fusion

Nuclear fusion is a potential future energy source where light elements are combined to form heavier elements, releasing energy. While not yet commercially practical, it holds the promise of being a clean, safe, carbon-free, and almost limitless energy source.

Benefits of Investing in Renewable Energy Sources

By investing in renewable energy sources, poor countries can not only reduce pollution but also gain economic benefits. Renewable energy creates three times more jobs than fossil fuel investments, and it is becoming increasingly affordable, with prices dropping rapidly. Additionally, it can help countries become less dependent on energy imports, protecting them from unpredictable fossil fuel price swings.

Provide access to affordable, clean fuels

Providing access to affordable, clean fuels and technologies is essential to reducing air pollution in developing countries. Here are some measures that can help achieve this:

Policy and Regulatory Changes

Governments and policymakers play a crucial role in promoting the adoption of clean fuels. This includes providing incentives, subsidies, and removing barriers for households to access and afford clean energy alternatives. For example, removing subsidies for fossil fuels and incentivizing the uptake of cleaner technologies can help make the transition to cleaner energy sources more affordable for low-income communities.

Supply Chain Considerations

Ensuring a stable supply of clean fuels is vital. This involves considering the entire supply chain, from production to delivery, to make these fuels readily available to the target population. For instance, in the context of household energy, electricity, liquefied petroleum gas (LPG), alcohol fuels, biogas, and compressed biomass pellets are some of the clean fuel options that can be considered.

Enhancing Production and Sustainability

Measures should be taken to enhance the production and long-term sustainability of clean fuels. This includes investing in the infrastructure and technology required to produce and distribute these fuels efficiently and effectively.

Education and Awareness

Educating communities about the benefits of adopting clean fuels and technologies is essential. Raising awareness about the health and environmental risks associated with traditional polluting fuels can help drive behavioral changes and encourage the adoption of cleaner alternatives.

Access to Clean Cooking Solutions

Access to clean cooking fuels and technologies is a critical aspect of reducing indoor air pollution, which has severe health impacts, particularly on women and children. By providing access to clean cooking solutions, such as advanced combustion cookstoves that meet WHO emission rate targets, governments can significantly reduce household air pollution and improve public health.

Collaboration and Partnerships

Collaboration between government agencies, development agencies, investors, and international organizations is vital to successfully providing access to affordable, clean fuels. For example, UNICEF works with partners to support sustainable energy solutions, such as providing solar lighting for schools and solar pumps for communities vulnerable to droughts and floods.

By implementing these measures, developing countries can make significant progress in providing access to affordable, clean fuels, which will help reduce air pollution and improve the health and well-being of their citizens, especially those from low-income communities.

Implement cleaner methods of transportation

Emissions from vehicles are a large contributing factor to air pollution. When governments do not regulate vehicle emissions, the amount of pollution in the air increases exponentially. Here are some ways that governments can cut down on vehicle emissions and implement cleaner methods of transportation:

Offer Public Transportation

Governments can provide buses and taxis, allowing more people to travel in one vehicle instead of having more vehicles on the road putting out emissions. In addition, cities can also provide options for walking and cycling to improve air quality.

Create Cleaner Fuels

Motor vehicles are a leading source of air pollutants that affect human health. Vehicle emissions contribute to the formation of ground-level ozone (smog), which can trigger health problems such as aggravated asthma, reduced lung capacity, and increased susceptibility to respiratory illnesses, including pneumonia and bronchitis. Therefore, it is important to create cleaner fuels that do not produce as many harmful emissions.

Encourage the Use of Electric Vehicles

Governments can encourage the use of electric vehicles by providing subsidies or incentives for people to purchase them. This will help reduce emissions from traditional gasoline or diesel-powered vehicles.

Improve Fuel Efficiency

Governments can also improve fuel efficiency standards for vehicles. This will help reduce the amount of fuel consumed and, in turn, reduce emissions.

Implement Anti-Idling Policies

Unnecessary idling of cars, trucks, and school buses pollutes the air, wastes fuel, and causes excess engine wear. Governments can implement anti-idling policies to reduce these emissions.

Improve indoor air quality

Improving indoor air quality in poor countries is a critical step in protecting the health of families, especially as indoor environments have higher levels of some pollutants than outdoor environments. Here are some detailed and direct strategies to improve indoor air quality in poor countries:

Improve ventilation

One way to lower indoor air pollution is to increase the amount of outdoor air coming inside. This can be done by opening windows and doors, using window or attic fans, or running window air conditioners with the vent control open. Mechanical systems that bring outdoor air into the home, such as energy-efficient heat recovery ventilators, are also an option for new homes.

Source control

Source control is often the most effective and cost-efficient way to improve indoor air quality. It involves eliminating or reducing the emissions of individual pollution sources. For example, asbestos sources can be sealed or enclosed, and gas stoves can be adjusted to decrease emissions.

Air cleaners and filtration

Air cleaners can help capture and remove pollutants from indoor air. When choosing an air cleaner, consider the efficiency of pollutant collection and the amount of air drawn through the cleaning element. Additionally, ensure regular maintenance according to the manufacturer's directions.

Reduce allergens

Allergens like pet dander, dust mites, and mold spores can trigger respiratory problems and allergies. To reduce allergens, vacuum carpets and rugs regularly, opt for hard-surface flooring instead of carpets, and wash bedding and drapes frequently in hot water. Clearing clutter and avoiding indoor plants can also help minimize allergens.

Change filters

If you have a forced-air heating system, regularly change the filters to trap dust and other airborne irritants. Electrostatic filters can be particularly effective. Additionally, consider having your ducts cleaned to remove trapped dust.

Use alternative fuels

In poor countries, burning wood, charcoal, kerosene, or other materials inside poorly ventilated homes for cooking, heating, or lighting can contribute to indoor air pollution. Access to cleaner and more affordable fuels, such as electricity, can help improve indoor air quality.

These strategies can help improve indoor air quality in poor countries, reducing the health risks associated with indoor air pollution and improving the overall quality of life for vulnerable communities.

Strengthen pollution monitoring

Strengthening pollution monitoring is a crucial step in reducing pollution in poor countries, and there are several ways to achieve this. Firstly, governments should invest in establishing and maintaining ground-level monitoring networks to collect reliable air quality data. For example, the World Bank found that there was only one PM2.5 ground-level monitor per 65 million people in low-income countries, highlighting the need for more robust monitoring infrastructure. Disseminating this air quality data to the public is also essential, as it raises awareness and empowers people to take action to reduce their exposure.

To strengthen pollution monitoring effectively, it is crucial to identify the main sources of air pollution in a specific context. For instance, in one city, transport might be the biggest contributor, while in another, the problem could be emissions from dirty cooking fuels used in homes. Understanding these sources enables targeted interventions to abate air pollution. Additionally, collaboration between different sectors, such as transport, industry, and agriculture, is vital to comprehensively address pollution.

Furthermore, strengthening pollution monitoring should go hand in hand with policy reforms and physical investments. Governments can play a significant role by implementing policies that support the transition to cleaner energy sources and technologies. For instance, policies that incentivize the use of electric vehicles, promote renewable energy sources, and regulate industrial emissions can have a significant impact on reducing pollution levels.

International organizations, such as the United Nations Environment Programme (UNEP) and the World Bank, also have a role in strengthening pollution monitoring in poor countries. UNEP, for instance, leads research and innovation and implements programs to tackle poor air quality globally. The World Bank has invested about $52 billion in addressing pollution in the past two decades and supports projects that strengthen air quality monitoring networks and build capacity for emissions tracking and enforcement in developing countries.
