Air Pollution: What Can We Do?

Air pollution is a pressing issue that affects the health of people worldwide and contributes to climate change. It is caused by the release of harmful particles, chemicals, and gases into the atmosphere, which can have detrimental effects on both the environment and human health. With an estimated 4.2 million premature deaths worldwide in 2019 attributed to air pollution, it is crucial to address this issue and find ways to improve air quality. This paragraph will discuss the causes of air pollution, its impacts, and potential solutions, including individual actions and policy interventions, to tackle this global problem.

Reduce vehicle emissions

Vehicle emissions are a major source of air pollution. In California, about half of air pollution comes from cars and trucks. In Minnesota, vehicle exhaust is a leading cause of air pollution. Similarly, in Washington, motor vehicles are the largest source of air pollution.

There are several ways to reduce vehicle emissions. Firstly, individuals can opt to drive less. Walking, biking, carpooling, and taking public transportation are all effective alternatives to driving alone. When driving, individuals can accelerate gradually, obey speed limits, and avoid idling, as these actions reduce fuel consumption and lower emissions. Keeping tires properly inflated also improves fuel efficiency and reduces emissions.

Another way to reduce vehicle emissions is to purchase fuel-efficient vehicles with low greenhouse gas emissions. Electric, hybrid, and compact fuel-efficient gas vehicles are cleaner alternatives to traditional gasoline-powered cars. For those who require a larger vehicle, comparing the fuel economy of different models can help identify the most environmentally friendly option.

Finally, maintaining vehicles and addressing any issues are crucial. A qualified automotive technician should be consulted if a vehicle's emission controls are not functioning properly, as indicated by a check engine light. Regular maintenance, such as fixing exhaust and oxygen sensor problems and keeping tires inflated, can also help reduce emissions.

By implementing these strategies, individuals can significantly contribute to reducing vehicle emissions and improving air quality.

Improve energy efficiency

Improving energy efficiency is a crucial step in reducing air pollution and can be achieved through various measures in different sectors.

One of the major contributors to air pollution is vehicle emissions. To combat this, individuals can opt for more fuel-efficient vehicles, such as electric cars, and reduce their overall car usage. Carpooling, using public transportation, biking, and walking are all effective ways to lower vehicle emissions and improve air quality. Additionally, maintaining vehicles and keeping tires properly inflated can also help reduce pollution.

In the energy sector, improving energy efficiency involves using less energy to achieve the same level of output. This can be done by adopting renewable energy sources, such as solar and wind power, and improving the energy efficiency of buildings through better insulation, energy-efficient windows, and smart thermostats. These measures not only reduce energy consumption but also lower energy costs for consumers and businesses.

At the industrial level, mandatory energy savings programs and the implementation of standards for heavy-duty vehicles and personal vehicles have proven successful in reducing air pollution. For example, China's mandatory energy savings programs in industry and building retrofits led to significant energy savings and a reduction of 1.2 gigatonnes of CO2 emissions in 2014.

On an individual level, people can contribute by using energy-efficient appliances, such as those with the ENERGY STAR label, and by practising energy-saving habits. This includes turning off lights and appliances when not in use, using smart power strips, and opting for fans instead of air conditioning.

By implementing these measures and improving energy efficiency across various sectors, we can significantly reduce air pollution, protect our health, and contribute to a healthier planet.

Reduce waste burning

Burning waste releases harmful chemicals and pollutants, including air pollutants, heavy metals, and toxic chemicals, which have been linked to various health issues such as lung and heart diseases, neurological problems, and cancer. To reduce waste burning and mitigate its impact on air pollution, several measures can be implemented:

Decentralize Waste Management

Promoting decentralized waste management systems at the community level can reduce the burden on centralized locations, lower transport costs, and decrease the likelihood of dumping and burning waste. This approach also creates job opportunities for informal workers and can be tailored to local waste streams.

Prevent Fires at Dumpsites

Measures such as reducing unsegregated organic waste and promoting the biomining of legacy waste are essential to preventing fires at dumpsites. Collaborating with state pollution control boards to install air quality monitoring devices can provide real-time alerts for smoke, enabling a quick response. Additionally, ensuring the proper design of landfills, including systems for collecting and processing methane, can help prevent combustion.

Verify and Acknowledge the Problem

Municipal corporations can conduct comprehensive surveys to estimate the amount of solid waste being burned in a city. This includes identifying burning hotspots, characterizing the burned waste, determining probable sources, and forecasting future waste generation. Creating a network of air quality monitoring stations and cross-collaboration between city agencies can help correlate burning instances with air quality, allowing for targeted actions and the assessment of implemented measures' effectiveness.

Establish a Robust Workforce

Municipal authorities can revise agreements with waste contractors to ensure door-to-door collection of all types of waste. Providing incentives for supervisors and sanitation inspectors can encourage on-ground monitoring and community recruitment, fostering a sense of ownership and responsibility within local communities.

Create Behavioral Nudges

Actively promoting positive behaviors, such as waste segregation at the source and discouraging burning, can enable behavioral shifts. Social and Behaviour Change Communication (SBCC) initiatives can highlight the negative consequences of waste burning and motivate communities to adopt responsible disposal practices. Identifying behavioral biases and understanding the reasons behind waste burning can help design effective nudges for positive change.

Support clean air initiatives

Supporting clean air initiatives is a great way to get involved in the fight against air pollution. Here are some ways to do so:

Advocate for Policy Change

Write to your local representatives and voice your support for cleaner air policies. This includes advocating for cleaner transport, energy-efficient homes, improved power generation, better waste management, and access to clean household energy. These policies will help reduce key sources of outdoor air pollution.

Plant and Care for Trees

Trees are nature's air purifiers. They filter pollutants, absorb carbon dioxide, release oxygen, and provide shade to cool our homes. Get involved in tree-planting initiatives and support organizations working to protect and restore forests.

Reduce Vehicle Emissions

Transportation contributes significantly to air pollution. Reduce your vehicle emissions by driving less and opting for more sustainable modes of transportation, such as walking, biking, carpooling, or using public transportation. If you drive, maintain your vehicle, keep tires properly inflated, and avoid idling, as this creates a hotspot of pollution.

Energy Conservation

Conserve energy by choosing energy-efficient appliances and heating systems. Turn off electrical appliances and lights when not in use, and consider alternative energy solutions like solar or wind power. Reduce your energy consumption to lower power plant emissions and protect natural resources.

Workplace Initiatives

Encourage your workplace to adopt environmentally friendly practices. Start a recycling program, promote double-sided printing, and turn off office equipment after hours. You can also suggest initiatives for employees to work remotely, reducing commute-related emissions.

By actively supporting and participating in clean air initiatives, we can collectively make a significant impact on improving air quality and protecting our health and environment.

Plant and care for trees

Trees are a natural remedy for air pollution. They act as the Earth's purification system by absorbing airborne chemicals and releasing oxygen. Trees can improve air quality in two main ways: dispersion and deposition. By crashing into trees and plants, concentrated clouds of minuscule particles get dispersed and diluted by the air, reducing the risk of inhalation by humans. The second way is deposition, where PM can easily get trapped in the waxy, hairy leaves of trees and shrubs. When it rains, most of these particles are washed away by water into drains.

To make the most difference in air quality, it is important to plant the right types of trees. Bigger canopies can trap more particles than smaller ones, and larger leaves can trap more pollutants than small ones. When it comes to leaf type, it is those with rough, rugged and hairy surfaces that act as the “best filters” for PM. For example, London plane trees emit high levels of volatile organic compounds, which can be bad for urban air pollution.

Trees can also improve air quality indirectly by shading surfaces and reducing temperatures. If buildings are shaded by trees, it reduces the need for conventional air conditioning and the emissions of greenhouse gases that come with it. Lower temperatures also decrease the risk of harmful pollutants like ground-level ozone that commonly spike on hot days in urban areas. Trees also mitigate the greenhouse gas effect by trapping heat, reducing ground-level ozone levels, and releasing oxygen.

To tackle global air pollution, it is important to halt deforestation and plant billions of trees. Ecosia, for example, is an organization committed to planting trees and spreading awareness about the vital role forests play in protecting our planet. They use their ad revenue to plant trees in deforested landscapes across South America, Africa, and Asia.
