Reducing air pollution from vehicles
Air pollution is a major environmental health problem affecting people in low-, middle-, and high-income countries. It is estimated to have caused 4.2 million premature deaths worldwide in 2019, with 89% of those occurring in low- and middle-income countries. One of the main sources of outdoor air pollution is vehicle emissions, which account for a significant amount of air pollution and greenhouse gas emissions.
To reduce air pollution from vehicles, policies and investments supporting cleaner transport are essential. This includes promoting alternative transportation options, such as buses, metros, and rails, as well as shifting to cleaner modes of power generation. Electric vehicles, flex-fuel vehicles, and plug-in hybrid electric vehicles are examples of alternative fuel vehicles that can help reduce pollution from cars and trucks. These vehicles use electricity or alternative fuels like ethanol blends, which are cleaner than regular gasoline or diesel.
In addition to alternative fuels, improving urban design and traffic management can also help minimize traffic-related air pollution. This includes measures such as reducing congestion, implementing ultra-low emission zones, and improving public transportation systems to encourage their use over private vehicles.
Furthermore, vehicle emission standards and regulations have been crucial in reducing pollution levels over the years. California's landmark motor vehicle pollution policies, for example, have resulted in cleaner air, reduced oil consumption, and lower greenhouse gas emissions. These policies have included the use of catalytic converters and the implementation of greenhouse gas emission standards for cars.
By combining the promotion of alternative transportation and fuels, improving urban design, and enforcing stricter vehicle emission standards, significant progress can be made in reducing air pollution from vehicles. These measures not only improve air quality but also contribute to the reduction of greenhouse gas emissions and the mitigation of climate change.

Waste management and treatment
Waste segregation is a critical aspect of waste management. This involves separating wet waste from dry waste. Wet waste can be used for compost, while dry waste can be easily recycled. By segregating waste, communities can reduce the amount of waste sent to landfills, thereby lowering air and water pollution levels. Proper waste segregation also makes it easier to apply different treatment processes, such as composting, recycling, and incineration. Additionally, segregated waste is cheaper to dispose of since it requires less manual sorting.
The treatment and disposal of liquid waste are particularly challenging due to its ability to spread and pollute other liquid sources, soil, and groundwater. Industrial wastewater treatment processes aim to treat wastewater produced by industries as a by-product. After treatment, the treated wastewater can be reused or released into a sanitary sewer or surface water. Some industries have successfully redesigned their manufacturing processes to reduce or eliminate pollutants. Treatment processes include brine treatment, solids removal, oils and grease removal, and the removal of toxic materials.
Solid waste management has evolved over time, with cities experimenting with solid waste disposal methods to manage human and horse waste. Today, solid waste management continues to be a significant challenge, especially in urban areas with high population growth and garbage generation rates. Sustainable solid waste management practices can contribute to achieving several United Nations Sustainable Development Goals, such as ensuring clean water and sanitation, creating sustainable cities, and mitigating climate change.
To address the issue of waste management and pollution, the world's environment ministers have expressed their commitment to working towards a pollution-free planet. The United Nations Environment Assembly (UNEA) has adopted resolutions targeting specific aspects of pollution, including air quality, water pollution, soil pollution, marine litter, and chemicals and waste. The Assembly has also devised an Implementation Plan to promote accelerated action and enhance capacities to address pollution.
