Strategic Environmental Assessment (SEA) is a process for the formal, systematic evaluation of the likely significant environmental effects of implementing a plan or programme, before a decision is made to adopt the plan or programme.  The SEA Directive requires that all plans and programmes that have the potential to have impacts on the environment are subject to SEA. However, in Ireland, certain plans and programmes have either not been subjected to SEA (Harnessing our Ocean Wealth – An Integrated Marine Plan for Ireland, 2012) or the Directive has been incompletely applied (Offshore Renewable Energy Development Plan, 2014).
