Mayors from 12 cities pledge to buy only all-electric buses from 2025

The mayors from 12 big cities around the world have pledged to add only all-electric buses starting  2025 to their public transport fleets.

The promise comes as an extension of the C40 Clean Bus Declaration Act, a 2015 initiative from C40, an international coalition of cities formed to cut harmful emissions and combat climate change.

Mayors of London, Paris, Los Angeles, Barcelona, Copenhagen, Quito, Vancouver, Cape Town, Mexico City, Seattle, Milan, and Auckland had adopted the resolution. They also promised to take steps to create a zero emission zone within their cities by 2030.

According to the mayors, they would hit the targets by collaborating with their providers to phase in more zero-emissions public transport vehicles. They will also push for adoption of alternative forms of transportation by every day commuters.

The cities will publicly report their progress every two years.

According to commentators, the pledge also comes as great news for electric bus makers like Proterra. The company has successfully established itself as a leader in the green bussing space and recently claimed one of its vehicles drove over 1,000 miles on one charge.

The policies outlined in the agreement aim to cut down air pollution, improve the quality of life for people and tackle climate change.

A third of greenhouse gas emissions from C40 cities come from transport with traffic being most significant source of air pollution.

London mayor Sadiq Khan said, ''This is just the first step – we are introducing further world-leading restrictions on polluting vehicles over the next few years, as well as cleaning up our bus fleet and keeping our pledge not to buy a single new double decker diesel bus, reported. We are also building brand new cycle lanes right across the city and focusing on reducing pollution around schools.

''I want to make London one of the greenest cities in the world – that's why I'm putting walking, cycling and zero emission public transport right at the heart of Londoners' day-to-day lives alongside energy efficient buildings, clean energy and increased recycling.''
