Air pollution, the greatest environmental risks to health says WHO

Microscopic pollutants in the air can penetrate respiratory and circulatory systems, damaging the lungs, heart and brain, killing 7 million people prematurely annually

Nine out of ten people breathe polluted air every day. In 2019, air pollution is considered by the World Health Organization, WHO, as the greatest environmental risk to health.

Microscopic pollutants in the air can penetrate respiratory and circulatory systems, damaging the lungs, heart and brain, killing 7 million people prematurely every year from diseases such as cancer, stroke, heart and lung disease. Around 90% of these deaths are in low- and middle-income countries, with high volumes of emissions from industry, transport and agriculture, as well as dirty cook-stoves and fuels in homes.

The primary cause of air pollution (burning fossil fuels) is also a major contributor to climate change, which impacts people’s health in different ways. Between 2030 and 2050, climate change is expected to cause 250 000 additional deaths per year, from malnutrition, malaria, diarrhea and heat stress.

In October 2018, WHO held its first ever Global Conference on Air Pollution and Health in Geneva. Countries and organizations made more than 70 commitments to improve air quality.

This year, the United Nations Climate Summit in September will aim to strengthen climate action and ambition worldwide. Even if all the commitments made by countries for the Paris Agreement are achieved, the world is still on a course to warm by more than 3°C this century.
