Air Quality Emerges as a Key Issue in Climate Health Discussions
Published
Air pollution is one of the world's biggest threats to the environment and to human health. Experts say it causes about 7 million premature deaths every year. Because many of the causes of air pollution also cause climate change, air quality is becoming an important topic in discussions about the climate.
The issue is attracting attention ahead of COP31, the next United Nations climate conference. Air pollution comes from sources such as burning fossil fuels, vehicle emissions, industry, and wildfire smoke. Reducing these sources can lower greenhouse gas emissions and also make the air cleaner for people to breathe. Researchers say that tackling both problems together can produce better results than treating them separately.
For Canadians, clean air is a particular concern. Wildfire smoke, which has affected many parts of the country in recent summers, can travel long distances and reach cities far from the fires. Health officials recommend that people pay attention to air quality reports and limit outdoor activity when pollution levels are high, especially children, older adults, and people with breathing problems.
Overall, the link between air quality and climate health is now receiving more attention from governments, scientists, and health organizations. Many experts believe that climate policies which also improve air quality could protect millions of lives and benefit communities around the world, including in Canada.
