Each year, thousands of Londoners die prematurely as a result of air pollution across the capital, and millions more face health threats every day. The city has breached legal limits for air quality every year since implementing them in 2010, and all of London’s boroughs fail both annual targets and World Health Organisation standards.
Some people are especially vulnerable to the dangers of air pollution – including children, the elderly, people of color, low-income communities and those with diabetes, heart disease or respiratory problems. These groups may suffer an increased risk of developing cardiovascular disease, cancer, asthma and other respiratory diseases; or of worsening conditions that are already present.
What we typically think of as air pollution is a mixture of small particles such as black carbon, gases like nitrogen oxides, ozone and sulphur dioxide.
