Environmental law enforcement being the responsibility of states, the financial crisis has further weakened certain national authorities in their fight against environmental crime.
According to a February 2016 policy brief issued by the EFFACE (European Union Action to Fight Environmental Crime):
“One overarching challenge is that the implementation of environmental law is a responsibility that is left up to the individual MS. The EU itself does not have the authority to enforce the provisions outlined in the EU’s legal framework and tools. As a result, the operation of enforcement institutions at the MS level varies and is uneven across the EU. Some MS have special investigative units while others have no environmental crime specialization. Evidence shows that many environmental crimes are not investigated or prosecuted by enforcement institutions for reasons of limited awareness, lack of resources and expertise, and complexity of establishing causality of environmental crime. The lack of financial resources is identified as a significant weakness or barrier to enforcement; this situation has become exacerbated in the recent financial crisis, at least in some MS”.
