4 major world cities pledge to eliminate diesel vehicles

MEXICO CITY (AP) — Host Mexico City has joined with Paris, Madrid and Athens in committing to eliminate diesel vehicles from their cities by 2025.

The C40 Mayors Summit announced the agreement Thursday. A statement said the commitment would reduce air pollution and related health issues in those cities, while also helping cities meet climate goals.

No details were offered about how such an ambitious goal would be achieved, although creating incentives for the use of alternative vehicles and promoting walking and bicycling were mentioned. Most heavy cargo trucks and public transportation buses operate on diesel fuel.

The mayors of dozens of the world's largest cities are meeting in Mexico City this week to exchange knowledge and discuss concrete steps to achieve carbon emission-reducing goals.
