DEFRA has today published its new Air Quality Strategy, for England (most aspects of air quality management are devolved matters). This document is here.
Scotland already has its own Air Quality Strategy, information is here. Wales and Northern Ireland are developing theirs.
The England document states :
(1) New legislation will create a stronger and more coherent framework. (This will be contained in the Environment Bill, which is not yet published save for the governance aspects).
(2) New England-wide powers will control major sources of pollution (some aspects listed below).
(3) New local powers will enable action in areas with an air pollution problem, including powers to create Clean Air Zones for all air pollution sources, in the Environment Bill, not just smoke, as exists currently (under the existing Clean Air Act).
(4) A commitment to bring all national and local monitoring data into a single online portal. Currently an online portal, with trigger alerts, exists for the London area.
(5) A commitment to publish a new target for fine particulates PM2.5, and evidence (early in 2019) on the action needed to achieve the WHO target of 10 micrograms per metre cubed. Note, the EU limit of 25 micrograms per metre cubed is met, and the second stage target of 20 micrograms per metre cubed is on target (the document states) for 2020.
(6) A commitment to provide a personal messaging system (see above comment re the London alert system).
(7) A commitment to creating a new target for reducing deposited reactive nitrogen (a target is specified).
(8) New legislation will compel manufacturers to recall non-road mobile machinery for failures in emissions control technology (this legislation is not yet published).
(9) New legislation will ban the sale of the most polluting fuels.
(10) Changes will be made to existing smoke control legislation, via the Environment Bill, to improve enforcement.
(11) Medium combustion plant emission standards will be reviewed.
(12) A National Air Pollution Control Programme will be developed with the devolved governments (as required by the EU National Emissions Ceilings Directive) for publication in 2019.
The above is a selection only, there are further commitments in the document itself.
