MAJOR WORLD CITIES COMMIT TO BAN DIESEL-POWERED AUTOMOBILES
Last week at the C40 Mayors Summit, four cities—Athens, Mexico City, Madrid, and Paris—committed to ban diesel-fueled automobiles in their cities by 2025, a move applauded by many environmental supporters. Diesel-fueled vehicles had previously been championed for emitting less carbon dioxide than gasoline-powered vehicles. The ban comes after local governments became attuned to the local pollution effects of diesel vehicles, in particular nitrogen oxides and particulate matter, which manufacturers have been slow to resolve.
