Overview

The Environment (Air Quality and Soundscapes) (Wales) Act 2024 ("the 2024 Act") became law on 14 February 2024. 

The 2024 Act seeks to improve the quality of our air environment and reduce the impacts of airborne pollution on human health, nature, the environment and our economy.

The 2024 Act creates a framework for the Welsh Ministers to set targets in relation to air quality and amends existing air quality legislation in relation to local air quality management, road user charging, anti-idling and smoke control such as the Environment Act 1995. The 2024 Act also creates new duties for the Welsh Ministers to take steps to promote awareness of the risks to human health and the natural environment caused by air pollution, and ways of reducing or limiting air pollution. 

The 2024 Act also places the Welsh Ministers and local authorities under a duty to promote active travel as a way of reducing or limiting air pollution and makes provision for this duty to be imposed by regulations, on other public authorities. The Act also requires the Welsh Ministers to produce a national strategy on soundscapes.

The Explanatory Notes to the 2024 Act provide detailed commentary on the various provisions.
