The SEA Directive - Directive 2001/42/EC on the assessment of the effects of certain plans and programmes on the environment - requires that an environmental assessment is carried out of certain plans and programmes which are likely to have significant effects on the environment.
Eleven sectors are specified in the SEA Directive. Competent Authorities (plan/programme makers) must subject specific plans and programmes within these sectors to an environmental assessment where they are likely to have significant effects on the environment.
