Mums for Lungs is a nonprofit, grassroots environmental campaign group, based in the United Kingdom, which raises awareness of the health effects of air pollution, particularly on children.

[1][2] Mums for Lungs was formed in London in 2017 by a small group of parents, including human rights lawyer Jemima Hartshorn.

[1][6] In 2021, Mums for Lungs won the Sheila McKechnie Foundation Best Community Campaign Award for its work.

[7] Mums for Lungs campaigns on a range of air pollution issues, including clean air guidelines and targets,[8] the expansion of London's Ultra Low Emission Zone;,[9][10][11] clean air zones, pollution from wood burning stoves [12][13][14] and diesel engines;[15][16] the role of pollution in childhood asthma,[17] car-free streets,[18][19] and cleaner travel to and from schools.

[20] Since 2018, one of its major ongoing campaigns has been supporting an initiative called School Streets, which temporarily close roads to motor traffic at school picking-up and dropping-off times to reduce the impact of pollution and improve safety.
