The Office of Environmental Protection (OEP) has carried out a programme of work looking in detail at the implementation of three regimes in place to assess the environmental effects of proposed developments: Environmental Impact Assessments; Strategic Environmental Assessment; and Habitats Regulations Assessment. Government aims to amend these current regimes and create a new approach with Environmental Outcomes Reports. The OEP has carried out research to provide evidence of what is working well in the current regimes and where there are barriers to effectiveness in order to inform future changes. The results of the research are available to be downloaded here.
