Air Pollution Solutions: Natural, Sustainable Materials

Air pollution is a pressing issue that affects the health of people worldwide and damages the planet. In 2019, the World Health Organization (WHO) reported that 99% of the global population lived in areas that did not meet its air quality guidelines, with 6.7 million premature deaths associated with the combined effects of ambient and household air pollution. To combat this, materials and strategies are needed to reduce emissions and improve air quality. This includes transitioning to cleaner energy sources, such as solar and wind power, improving waste management practices, promoting energy efficiency, and encouraging the use of electric vehicles and public transportation. Individual actions, such as reducing gasoline and electricity consumption, using energy-efficient appliances, and opting for eco-friendly products, can also contribute to lowering air pollution levels. Addressing air pollution requires a combination of policy interventions, technological advancements, and behavioural changes to protect public health and the environment.

Reduce vehicle usage, opt for walking, biking, carpooling, or public transport

Air pollution is a major environmental health problem affecting individuals in low-, middle-, and high-income countries. In 2019, 99% of the global population lived in areas that did not meet the World Health Organization's (WHO) air quality guidelines. To combat this, individuals can take steps to reduce their vehicle usage and opt for more sustainable modes of transportation, such as walking, biking, carpooling, or public transport.

Walking and biking are excellent alternatives to driving, especially for shorter distances and when the air quality index is below 100. They offer environmental and health benefits, as they do not produce emissions and help improve air quality. Additionally, they promote physical activity and reduce congestion on the roads. By leaving your car at home and choosing to walk or bike, you can significantly contribute to reducing air pollution.

Carpooling is another effective way to reduce vehicle usage. When you share a ride with colleagues, friends, or neighbours, you decrease traffic congestion and lower per-person emissions, particularly in urban areas. Carpooling also reduces the number of vehicles on the road, leading to improved air quality. If you cannot walk, bike, or carpool, public transportation is a viable option. Buses and trains have significantly lower carbon dioxide (CO2) emissions per passenger compared to car travel, often six to eight times lower. Utilizing public transportation helps reduce your individual carbon footprint and contributes to a cleaner environment.

To further minimize vehicle usage, it is essential to plan your trips efficiently. Combining multiple errands into a single trip can reduce the overall distance travelled, decreasing your carbon footprint. Additionally, proper vehicle maintenance, such as keeping tires properly inflated and fixing exhaust and oxygen sensor problems, can help reduce emissions when driving is necessary. Finally, when purchasing a new vehicle, consider choosing the most efficient, lowest-emitting option, such as a zero-emission electric car.

Energy efficiency is a critical aspect of reducing air pollution. By using energy-efficient appliances and heating systems, we can significantly lower our environmental footprint and improve air quality. Here are some ways to choose and use energy-efficient appliances and heating systems to combat air pollution:

Heating Systems

When it comes to heating systems, there are several energy-efficient options available that can help reduce air pollution. One option is to use a heat pump, which can heat and cool your home by moving heat from the surrounding air instead of generating it. Heat pumps are more efficient than traditional heating systems that rely on separate units for heating and cooling. For example, an ENERGY STAR-certified heat pump water heater uses 70% less energy than a standard electric water heater, resulting in significant energy and cost savings. Additionally, consider insulating your water heater and any accessible hot water pipes to prevent heat loss and improve energy efficiency.

Efficient Appliances

In your home, look for the ENERGY STAR label when purchasing appliances. These products are certified by the US Environmental Protection Agency (EPA) to deliver superior energy efficiency and savings. For example, Energy Star-labeled ceiling fans with light fixtures are far more efficient than conventional units, providing the same level of comfort while consuming a fraction of the energy. Similarly, when it comes to lighting, replace energy-hungry incandescent bulbs with compact fluorescent light bulbs or LED lights, which use significantly less energy.

Reduce Energy Consumption

In addition to choosing energy-efficient appliances, it is essential to adopt practices that reduce overall energy consumption. This includes simple actions such as turning off electrical appliances when not in use, using smart or programmable thermostats to regulate temperature, and opting for fans instead of air conditioning whenever possible. These small changes can collectively make a significant impact on reducing energy waste and lowering energy costs, which has a positive effect on air quality.

Industrial and Transport Efficiency

While individual actions are important, it is also crucial to address air pollution on a larger scale. This includes improving energy efficiency in industrial sites and transportation. For example, implementing mandatory vehicle fuel efficiency standards and encouraging the use of electric vehicles can significantly reduce transport-related emissions, especially in densely populated cities. Additionally, supporting initiatives that promote energy-efficient practices in industries, such as mandatory energy-saving programs and building retrofits, can lead to substantial reductions in air pollution and improve public health.

By choosing energy-efficient appliances and heating systems, both in our homes and on a broader scale, we can play a vital role in reducing air pollution, protecting the environment, and safeguarding public health.

Use eco-friendly paints and cleaning products

Eco-friendly paints and cleaning products are an effective way to reduce air pollution. Volatile organic compounds (VOCs) and particulate matter (PM) are common in traditional paints and cleaning products, and they can penetrate deep into the lungs, triggering asthma attacks and worsening respiratory illnesses.

Paints

When choosing paints, opt for eco-friendly, non-toxic, and biodegradable options. These paints often have low-to-no VOC content, reducing hazardous air pollutants and improving indoor and outdoor air quality. Some recommended brands include:

• Behr's VOC-free products: Stain and mould-resistant, LEED and GREENGUARD GOLD certified, and available at Home Depot.
• ECOS Interior Air Purifying Paint: Eco-friendly, zero VOC, allergy-safe, and certified by various health and safety standards. It is important to note that ECOS products should be stored in a dry place, out of direct sunlight, and at specific temperatures.
• Benjamin Moore's Eco Spec line: 100% acrylic interior paint that is VOC-free, emission-free, and Green Seal certified for its protective limits on toxins and sustainable packaging.
• The Organic & Natural Paint Co.'s AFM Safecoat: Medically approved, 100% VOC-free, and free of HAPs (Hazardous Air Pollutants).

Cleaning Products

When it comes to cleaning products, choose water-based options labelled 'zero VOC'. These products are safer for the environment and your health. Avoid toxic chemicals, and opt for natural substitutes instead. Properly seal cleaners and other chemicals to prevent evaporation into the air.

Additionally, consider the following general tips to reduce air pollution:

• Use less energy by choosing energy-efficient appliances and heating systems.
• Turn off electrical items when not in use.
• Conserve electricity by adjusting your thermostat settings.
• Participate in local energy conservation programs.

Reduce waste and recycle

Recycling is an important way to reduce air pollution. By recycling, we can significantly reduce the demand for raw materials, which in turn reduces the need for mining, logging, and other activities that can harm ecosystems and release pollutants into the air. For example, recycling paper reduces the need for tree cutting, preserving forests and maintaining the planet's carbon balance. Trees absorb carbon dioxide, and when they are cut down, this stored carbon is released into the atmosphere. Recycling aluminium is another way to reduce air pollution, as the process requires only 5% of the energy needed to produce the same amount of aluminium from raw materials, resulting in fewer emissions.

Recycling also helps to reduce the amount of waste in landfills, which are a significant source of air pollution. Landfills are noisy, smelly, and ugly, and they take up a lot of space. Recycling can help to reduce the volume of waste in landfills by up to 50%. Additionally, recycling reduces the costs of waste disposal and the amount of litter on roadways.

On a broader level, communities that adopt effective recycling programs can reduce their overall waste management costs and energy consumption, which positively impacts pollution levels. Recycling saves energy by reducing the need to extract, transport, and process raw materials, which often involves burning fossil fuels and releasing harmful gases into the atmosphere.

To reduce waste and recycle effectively, individuals can take several steps. Firstly, it is important to separate recyclable materials from general waste and to dispose of them properly. This includes paper, plastic, metals, and organic materials. Secondly, individuals can reduce their consumption of single-use items and disposable products, opting instead for durable and reusable alternatives. For example, using reusable grocery bags instead of plastic bags can reduce plastic waste.

Finally, individuals can support businesses and products that use recycled materials. Choosing products made from sustainable sources, such as bamboo or hemp, can also help to reduce the demand for raw materials and encourage recycling.

Plant trees and support local initiatives

Planting trees and supporting local initiatives are two effective ways to combat air pollution. Trees play a critical role in improving air quality by removing air pollutants and greenhouse gases from the atmosphere. They achieve this through a few key mechanisms:

Firstly, trees intercept and temporarily catch particulate matter, such as PM2.5, on their leaves and stems. These fine particles would otherwise be inhaled and cause serious health risks. When it rains, the trapped particles are washed off and dissolved into the soil or stormwater runoff.

Secondly, trees absorb gaseous molecules of pollutants like sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone through tiny pores on their leaf surfaces called stomata. Once inside the leaf, these gases are broken down and permanently converted, preventing their harmful effects on human health and the environment.

Trees also help reduce air temperature, which in turn lowers energy consumption in buildings and the associated emissions from power sources. This dual effect of trees is particularly beneficial in urban areas, where they can provide shade and cool homes, reducing the need for air conditioning.

In addition to planting trees, supporting local initiatives can be a powerful way to combat air pollution. Local governments and organizations often have programs aimed at reducing air pollution and promoting sustainability. These initiatives may include passing local ordinances, creating incentives for environmentally friendly practices, and educating residents on best practices.

Individuals can get involved by contacting local representatives and expressing support for cleaner air policies. Additionally, participating in community programs, such as the Small Business Environmental Assistance Program, can help local businesses reduce their environmental impact and emissions. By combining individual efforts with community initiatives, we can collectively make a significant impact on improving air quality.
