Network Overview

C40 launched in 2018 a new Air Quality Network focused on helping cities develop and implement air quality policies and solutions in support of efforts to measure, understand and reduce air pollution to improve public health and meet climate goals.

Growing air pollution in cities presents a potential challenge to achieving the goals of the Paris Agreement and limiting global temperature rise to 1.5°C. Air pollution is responsible for 7 million premature deaths every year according to the World Health Organisation (WHO), with cities across almost every continent experiencing air pollution that breaches WHO guidelines. 91 percent of urban dwellers are regularly forced to breathe dangerously polluted air, as measured by WHO standards.

C40’s Air Quality Network is focused on helping cities identify and implement actions that reduce air pollutants and greenhouse gas emissions. By identifying climate-friendly solutions that also address the public health crisis of air quality, the Network will support member cities to overcome political barriers and build public support for bold action. Additionally, the AQ Network will support cities to advocate for accelerated action because of the immediacy of the air pollution crisis and health impacts in cities around the world.

The Air Quality Network will convene C40 cities and serve as a platform to support cities share best practices, knowledge and solutions to meet their public health and climate goals. The Air Quality Network will also enable the delivery of air quality-climate solutions in coordination with C40’s transportation, energy, buildings, waste and adaptation networks.

Air Quality Network Focus Areas

The Network has identified three focus areas / work streams to guide best practice exchange and collaboration amongst cities. Based on consultations with cities and C40's Clean Air Cities Declaration, the Network's 2019-2021 priorities are below.

Monitoring and Measurement – Improve air quality data collection, analysis, and communication in cities to identify sources, raise awareness, track progress, evaluate risk, and enforce policy

Health Impact Analysis – Establish health impacts of air pollution or the health benefits of local action in cities to strengthen the case for action

Policy Implementation – Identify and deliver high impact actions that address the most polluting sources within cities

The Air Quality Network is led by Bengaluru and London.
