The landscape of environmental regulation is currently undergoing its biggest change in decades. To help make sense of this, this session will provide a clear, practical overview of the most significant legal and regulatory developments shaping the sector and impacting on infrastructure delivery.
It will also evaluate the appointment of “Lead Environmental Regulators” and one “super regulator” (water) and the extent to which this will facilitate more joined-up approaches to achieving climate and sustainability goals in major infrastructure project delivery.
