Network Overview

The Low Emission Vehicle (LEV) Network focuses on areas of municipal action critical for facilitating the uptake Low Emission Vehicles in cities.

Transportation is one of the most significant contributors to climate change, accounting for 27% of global CO2 emissions, and is the fastest growing source of greenhouse gas emissions.[i] Low Emission Vehicles (LEVs) are vital for addressing climate change and improving the efficiency of vehicle fleets as they produce lower GHG emissions than conventional fossil fuel vehicles. Each electric vehicle that displaces a conventional car saves approximately 1.5 tons of CO2 per year.[ii] This represents a 62% reduction compared to a petrol-powered car and a 53% reduction compared to a diesel-powered car.

Low Emission Vehicle Network Focus Areas

The C40 Low Emission Vehicle Network is currently working with C40 cities that are pursuing cleaner vehicle technologies to help reduce transport emissions. The network serves as a platform for C40 cities to share best practices and policies to reduce emissions by promoting the use of electric and other low emission vehicles. By bringing cities together, and convening and collaborating with key industry stakeholders, the network facilitates and accelerates the implementation of low emission vehicle strategies. Cities participating in the network have prioritized four focus areas around which they are actively sharing policies and strategies with one another. The focus areas are:

Citywide LEV strategy - Developing and refining low emission vehicle strategies for cities

Infrastructure - Planning for EV charging, hydrogen and other types of refueling infrastructure   

Incentives - Increasing LEV incentives to promote LEV uptake

Fleets - Promoting LEVs in bus, taxi, municipal and other citywide fleets

The Low Emission Vehicles Network is led by London.

Clean Bus Declaration

Cities of the Low Emission Vehicles Network collectively forged an international Declaration on Clean Buses, demonstrating a commitment by signatory C40 cities to reducing emissions and improving air quality by incorporating low- and zero-emission buses in their fleets. The Declaration is a call to global manufacturers, public transport operators, leasing companies, multilateral development banks, and other funding agencies to support city ambitions to decarbonize urban mass transport.

The Clean Bus Declaration is an open document and C40 welcomes additional signatory cities. 

The graphic above reflects figures for the first 26 signatory cities.

Like all cities, many of the challenges facing New York City are unique, but we know that solutions come from the entire globe. Sharing knowledge allows us to improve and speed up learning and deployment of climate change actions. The exchange spearheaded by the global C40 Low Emission Vehicle Network allows collaborating cities to share innovations and learn from each other. For example, we have applied valuable lessons from Bogota and Amsterdam in crafting our charging infrastructure strategy, while also sharing New York's actions to make 20% of new off-street parking EV charger ready.
