Part 1: Environmental Governance Chapter 1: Improving the natural environment Section 2: Environmental targets: particulate matter
Subsection (1) introduces a requirement for the Secretary of State to set a target for an annual mean concentration level of fine particulate matter (PM2.5) in ambient air, in secondary legislation by regulations. These regulations will be made having obtained expert advice as to the date that the target can be achieved and having considered the full economic analysis in line with section 4(1).
	Subsection (2) provides clarification that the fine particulate matter target is not required to be set for 15 years in the future, and therefore may not be a long-term target as defined in section 1. This could be the case if the independent expert advice is that the target could be achieved more quickly.
	Subsection (3) defines fine particulate matter (PM2.5).
	Subsection (4) specifies that regulations setting the target can also define "ambient air".
	Subsection (5) clarifies the duty to set a target for fine particulate matter in this section does not discharge the duty on the Secretary of State to set a further long-term target for air quality under section 1.
	Subsection (6) clarifies the elements of the environmental targets framework set in section 1 that apply to the fine particulate matter target. These elements include the provisions that specify that the target will be set by secondary legislation that will specify the standard to be achieved and the date by which it will be achieved, as well as the details regarding how the target will be measured.
	Subsection (7) defines the "PM2.5 air quality target" as being the target set under subsection (1).
