Four major cities to ban diesel vehicles by 2025

The leaders of four major global cities say they will stop the use of all diesel-powered vehicles from their streets by 2025.

The mayors of Paris, Mexico City, Madrid and Athens say they are implementing the ban to improve air quality.

This was announced in Mexico City during the C40 Mayors Summit which took place this week.

Air pollution is a major problem around the world, The World Health Organization (WHO) says that around three million deaths every year are linked to exposure to outdoor air pollution. Diesel engines contribute to this problem in two key ways. through the production of particulate matter (PM) and nitrogen oxides (NOx). Very fine soot PM can penetrate the lungs and can contribute to cardiovascular illness and death.

Nitrogen oxides can help form ground level ozone and this can exacerbate breathing difficulties, even for people without a history of respiratory problems.

They said that they will give incentives for alternative vehicle use and promote walking and cycling.

There is also a campaign in the U.K. to get London’s mayor to sign on to the diesel ban, the British news organization said.
