Compliance with these regulations is enforced through monitoring, inspections, and penalties for non-compliance.

2. Emission Controls: Technologies for controlling air pollution encompass a wide range of approaches tailored to specific pollutants and sources. For example, particulate matter can be reduced through the use of filters and electrostatic precipitators, while nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions can be mitigated using selective catalytic reduction (SCR) and flue gas desulfurization (FGD) systems, respectively.

3. Promotion of Clean Energy: The transition to clean energy sources is driven by a combination of regulatory mandates, incentives, and market forces. Renewable energy technologies, such as solar photovoltaics and wind turbines, have seen rapid growth in deployment, supported by government subsidies and falling costs. Additionally, policies to phase out coal-fired power plants and incentivize the adoption of natural gas and nuclear power contribute to reducing air pollution from the energy sector.

4. Public Transportation and Active Mobility: Investments in public transportation infrastructure, such as bus rapid transit (BRT) systems and metro rail networks, aim to provide viable alternatives to private car usage, thereby reducing traffic congestion and vehicle emissions. Initiatives to promote cycling and walking include the development of bike lanes, pedestrian-friendly streets, and bike-sharing programs in urban areas.

5. Green Infrastructure: Green infrastructure solutions offer multiple benefits beyond air quality improvement, including urban heat island mitigation, biodiversity conservation, and stormwater management. Green roofs, for example, reduce heat absorption and energy consumption in buildings while capturing rainwater and filtering pollutants from runoff. Urban green spaces also provide recreational opportunities and enhance overall quality of life.
