Pupils from Woodside Academy joined dozens of school children in Bradford taking part in a national campaign to help make the air cleaner where they live.
As part of Clean Air Day on Thursday, we joined a council-run event to learn more about air pollution and what can be done to improve our environment.
In 2022, Bradford launched its Clean Air Zone (CAZ) and the city subsequently recorded its lowest level of air pollution since records began.
Funding from charges raised by the CAZ has gone to help schools to try and reduce pollution in their areas.
Clean Air Day is an annual event aimed at raising awareness about the importance of clean air for people's health and the environment. It aims to inspire individuals, communities and organisations to take action towards reducing air pollution.
