Section 2 Environmental targets: particulate matterI1I2

The Secretary of State must by regulations set a target (“the PM_2.5 air quality target”) in respect of the annual mean level of PM_2.5 in ambient air.

The PM_2.5 air quality target may, but need not, be a long-term target.

In this section “PM_2.5” means particulate matter with an aerodynamic diameter not exceeding 2.5 micrometres.

Regulations setting the PM_2.5 air quality target may make provision defining “ambient air”.

The duty in subsection (1) is in addition to (and does not discharge) the duty in section 1(2) to set a long-term target in relation to air quality.

Section 1(4) to (9) applies to the PM_2.5 air quality target and to regulations under this section as it applies to targets set under section 1 and to regulations under that section.

In this Part “the PM_2.5 air quality target” means the target set under subsection (1).
