Conventions For A Cleaner Future: Reducing Pollution's Impact

Air pollution is a pressing issue that has severe health and environmental consequences. It is caused by various factors, including the combustion of petroleum products, coal, wood, or agricultural waste, as well as industrial processes and vehicle emissions. To combat this, the Convention on Long-Range Transboundary Air Pollution (CLRTAP) was established in 1979, bringing together 51 countries from Europe, North America, and Japan to tackle acid rain through intergovernmental cooperation. Additionally, the London Convention of 1972, with 87 signatory states, aims to control marine pollution by dumping waste and other matter. These conventions have been successful in reducing harmful emissions and protecting the environment, but more needs to be done, especially in addressing the pollution caused by low and middle-income countries.

Reducing air pollution through intergovernmental cooperation

Air pollution is a pressing issue that affects people worldwide, with toxic air pollutant levels far exceeding the World Health Organization's guidelines. While there have been efforts to combat this issue, such as the Convention on Long-Range Transboundary Air Pollution (CLRTAP), which has successfully reduced harmful emissions in Europe and North America, more needs to be done to include low and middle-income countries in these efforts. This article will discuss the importance of reducing air pollution through intergovernmental cooperation and the benefits it can bring.

The Impact of Air Pollution

Air pollution has severe health consequences, contributing to diseases in almost all organ systems. Outdoor air pollution, primarily caused by the combustion of petroleum products and coal, has been linked to increased respiratory and cardiovascular morbidity and mortality. Additionally, indoor sources of air pollution, such as biomass burning, also contribute significantly to outdoor air pollution, particularly in heavily populated areas. It is important to recognize that air pollution does not respect international borders, and a collaborative approach is necessary to address this global issue effectively.

Benefits of Intergovernmental Cooperation

Intergovernmental cooperation has proven to be key in achieving cleaner air. The CLRTAP, for instance, has brought together 51 countries from Europe, North America, and Japan, resulting in a substantial reduction in harmful emissions. By working together, governments can tackle the shared causes of air pollution and climate change, allocating resources effectively and implementing proven solutions. This collaboration also enables the sharing of scientific knowledge, technical expertise, and policy approaches, leading to more informed decision-making and innovative solutions.

Examples of Successful Cooperation

One successful example of intergovernmental cooperation is the UNECE Convention on Long-range Transboundary Air Pollution, signed by 32 countries in the pan-European region in 1979. This treaty created a framework for international cooperation to reduce air pollution, leading to significant emission reductions in the region. Another example is the "London Convention," which aims to control marine pollution by dumping wastes and other matter. This convention has been in force since 1975, with 87 states currently committed to promoting the effective control of all sources of marine pollution.

Preventing marine pollution by dumping of waste

The Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, or the London Convention, is one of the first global conventions to protect the marine environment from human activities. It has been in force since 1975 and currently has 87 member states. The London Convention was a major achievement, marking the first steps to put the environment centre stage and hold humanity accountable for the harm it has done to the ocean.

The London Convention's objective is to promote the effective control of all sources of marine pollution and to take all practicable steps to prevent pollution of the sea by dumping waste and other matter. The convention categorises waste into black, grey, and white lists. The black list includes organohalogen compounds, mercury compounds and pure mercury, cadmium compounds and pure cadmium, any type of plastic, crude oil and oil products, refined petroleum and residue, highly radioactive waste, and biological or chemical warfare materials. Dumping these materials is prohibited. The grey list includes water highly contaminated with arsenic, copper, lead, zinc, and other substances. Dumping these materials requires a special permit from a designated national authority and that certain conditions are met. The white list includes all other materials not mentioned on the other two lists, which are deemed safe and not to be dumped on vulnerable areas such as coral reefs.

The London Protocol, agreed upon in 1996, modernises the London Convention and will eventually replace it. Under the London Protocol, all dumping is prohibited except for possibly acceptable wastes on the "reverse list". The London Protocol also includes extended compliance procedures and technical assistance provisions, and a "transitional period" that allows new contracting parties to phase in compliance with the protocol over a period of five years, provided certain conditions are met.

In the United States, the Marine Protection, Research and Sanctuaries Act (MPRSA), enacted by the U.S. Congress in October 1972, implements the requirements of the London Convention. The MPRSA regulates the transportation and disposition of materials in the ocean, which would adversely affect human health, welfare, or amenities, or the marine environment, ecological systems, or economic potentialities. The EPA, the United States Army Corps of Engineers, and the United States Coast Guard work together to implement the MPRSA.

Reducing air pollution at an individual level

The 1979 UNECE Convention on Long-range Transboundary Air Pollution was the first international treaty to address air pollution on a broad regional basis. The convention has been successful in reducing harmful emissions and limiting the damage caused by air pollution to human health and the environment.

At an individual level, there are several ways to reduce air pollution and limit its harmful effects:

Reduce Vehicle Usage

Vehicle exhaust is a major source of air pollution. Opting to carpool, use public transportation, or even better, walk or bike, can significantly decrease air pollution. Electric vehicles are also a good alternative as they do not rely on fossil fuels.

Keep Your Vehicle Well-Maintained

Ensure your vehicle is in good condition. Fix any exhaust and oxygen sensor problems as soon as possible. Regularly check your tire pressure, as under-inflated tires can lower gas mileage, especially at lower speeds.

Avoid Idling

An idling engine, especially in buses and large trucks, creates a concentrated hotspot of pollution. Avoid leaving your engine running when stationary for extended periods. Schools and daycares can implement no-idling policies with the help of parents and teachers.

Avoid Open Burning

Burning garbage, leaves, or other waste is dangerous to your health and the environment and is often illegal. Contact your local authorities to arrange for trash hauling services if you are currently burning your waste.

Limit Backyard Fires

Smoke from fires can cause unhealthy conditions, especially for those with asthma or other lung conditions. Keep fires small and brief, and avoid them during air quality alerts. Only burn dry firewood, and never burn waste, even yard waste.

Plant and Care for Trees

Trees absorb carbon dioxide and release oxygen into the atmosphere, helping to cool homes and filter pollutants.

Use Electric Lawn Equipment

Gas-powered lawn equipment like lawnmowers and leaf blowers often lack pollution control devices. Use electric or hand-powered alternatives instead.

Conserve Energy

Choose energy-efficient appliances and heating systems, and turn off electrical items when not in use. Consider investing in renewable energy sources, such as solar panels, to power your home.

Reducing water pollution through chemical waste treatment

The "Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter 1972", or the "London Convention" for short, is one of the first global conventions aimed at protecting the marine environment from human activities. The convention has been in force since 1975 and currently has 87 signatory states. Its objective is to promote the effective control of all sources of marine pollution and to take all practicable steps to prevent pollution of the sea by dumping waste.

To reduce water pollution through chemical waste treatment, here are some key steps:

Wastewater Treatment

Wastewater treatment facilities are highly effective in reducing water pollution. These facilities employ chemical, physical, or biological processes to remove nearly all pollutants from wastewater before it is released back into the environment. To ensure proper functioning, it is crucial to maintain the equipment in good condition and utilize sensors such as pH sensors, conductivity sensors, and oxidation reduction potential sensors to monitor the removal of contaminants.

Plastic Waste Reduction

Plastics are a significant contributor to water pollution, with an estimated 9-12 million tons of plastic reaching the ocean each year. To address this issue, it is recommended to avoid using plastics whenever possible, seek alternatives to plastic bottles, utensils, and straws, and recycle plastic items whenever possible.

Water Conservation

Conserving water is essential to maintaining its purity and protecting the environment. This can be achieved through simple daily habits such as turning off the water while shaving or brushing teeth, taking shorter showers, and using water-efficient toilets. Additionally, if you have a garden, try to use only the amount of water your plants need.

Proper Disposal of Household Chemicals

It is important to never dispose of household chemicals, cleaning agents, or medications down the sink or toilet. Instead, look for designated hazardous waste collection days or facilities in your area to ensure proper disposal.

Stormwater Management

Stormwater can pick up harmful pollutants as it flows along sidewalks, streets, and lawns, eventually carrying them into storm drains, streams, and rivers. By treating and managing stormwater through processes like sand filtration, electrocoagulation, reverse osmosis, and advanced oxidation, we can reduce the amount of pollution that reaches our oceans.

Green Agriculture

Agriculture is the primary cause of water pollution. By adopting green agriculture practices, such as planting trees and other plants near bodies of water to act as buffers, we can prevent chemicals from being washed away during rainfall. Additionally, avoiding the use of pesticides containing harmful chemicals can reduce the amount of toxic substances entering our waterways.

Reducing air pollution through vehicle emissions control

The UNECE Convention on Long-range Transboundary Air Pollution, signed in 1979, was the first international treaty to address air pollution on a broad regional basis. It has contributed significantly to the development of international environmental law and has created a framework to control and reduce the harm caused by transboundary air pollution.

One of the key sources of air pollution is vehicle emissions. Here are some ways in which air pollution can be reduced through vehicle emissions control:

Drive Less

A simple way to reduce vehicle emissions is to drive less. This can be achieved by carpooling, biking, taking public transportation, or even working from home. Driving less means fewer emissions, and it can also save money on fuel costs.

Choose Fuel-Efficient Vehicles

When purchasing a new vehicle, opting for a fuel-efficient model with low greenhouse gas emissions can benefit the environment and potentially save money. Plug-in hybrid electric vehicles, hydrogen fuel cell vehicles, and cleaner-burning gasoline vehicles are examples of fuel-efficient options.

Maintain Your Vehicle

Regular maintenance and tune-ups can help reduce emissions. This includes fixing exhaust and oxygen sensor problems, keeping tires properly inflated, and using the recommended motor oil. Well-maintained vehicles are more fuel-efficient and produce fewer emissions.

Reduce Idling

Unnecessary idling of vehicles pollutes the air and wastes fuel. Modern vehicles do not need to be warmed up in winter, so turning on the engine only when ready to drive can help reduce emissions. This is especially important for school buses, as idling diesel buses expose children to diesel exhaust.

Optimize Deliveries

When ordering home deliveries or shopping online, consolidating packages into a single shipment and choosing longer delivery time windows can help delivery trucks optimize their routes and reduce unnecessary trips.

Use Efficient Lawn and Gardening Equipment

Gas-powered lawn and gardening equipment emit significant amounts of pollutants. Opting for electric or hand-powered alternatives, or using commercial-grade landscaping machinery with advanced emissions reduction technologies, can help reduce pollution.

By implementing these measures, significant reductions in vehicle emissions and improvements in air quality can be achieved, contributing to a healthier environment and improved public health.
