John works in our Brussels office in the Wildlife and Habitats Programme. He specialises in the laws relating to marine conservation, including species protection, marine protected areas, and the conservation of marine habitats.

Some of John’s recent work with ClientEarth includes:

  • A legal complaint to protect the Dogger Bank marine protected area from the harmful impacts of industrial fishing;
  • A successful legal and advocacy campaign requiring EU countries to prevent dolphin and porpoises from being incidentally captured and killed in fishing nets;
  • Advocating with the EU institutions for better implementation of marine conservation laws and policies.


John has worked as lawyer with the Irish law firm A&L Goodbody, specialising in commercial dispute resolution and regulatory investigations. Just before joining ClientEarth, he pursued his passion for environmental law by studying for a master’s degree at University College London.


John is qualified to practise as a lawyer in Ireland and in England and Wales. He holds an LLM in Environmental Law and Policy from University College London and an LLB in Law from Trinity College, the University of Dublin. His academic work has been published in the Journal of Environmental Law, for which he was awarded an Honourable Mention in the 2020 Richard Macrory Prize for Best Article.

I joined ClientEarth because it is an incredibly dedicated and innovative organisation, which has used the law to tackle many of the world’s most serious environmental challenges. I am delighted to work here as a lawyer helping to restore the beautiful ocean and protect its marvellous species and habitats.
