Air pollution. From smog in cities to smoke inside homes, pollution is a significant threat to health and the climate. Ambient air pollution causes 4.2 million deaths annually from stroke, heart disease, lung cancer, and acute and chronic respiratory diseases.
Nearly all of the world’s population lives in locations where air quality exceeds WHO standards. While both rich and developing nations are affected by ambient pollution, low- and middle-income countries bear the burden—the WHO suffers the most in the western Pacific and Southeast Asia.
The sources of pollution air are numerous and relevant. Significant external pollution sources include residential energy for cooking and heating, vehicles, power generation, agricultural / waste incineration, and industry.
Policies and investments supporting integrated policies that support sustainable land use, clean domestic energy and transportation, energy-efficient housing, power generation, industry, and municipal waste management are key to ambient pollution. Can effectively reduce resources.
Climate and ecosystem
Air quality is closely linked to the global climate and ecosystem. Many air pollution causes (combustion of fossil fuels) are also sources of greenhouse gas emissions. As a result, policies to decrease pollution provide “win-win” methods for both climate and health, reducing the burden of pollution-related diseases while minimising the impact of climate change. Contributes to near and long term reduction.
