This section requires the Department to consider whether the emissions targets in sections 3 and 4 are consistent with the target in section 1(1). The Department is further required, within 2 years of the Act achieving Royal Assent, to either update these targets using the powers in section 5 or lay a statement before the Assembly explaining why one or both of the targets doesn’t need to be updated. The conditions in section 54 do not apply to regulations made under this section (but the duty in section 56 to request the advice of the Committee on Climate Change does).
