Anaïs Berthier is a Senior Lawyer in our Brussels office and leads our work on strengthening the rule of law. She is specialised in European environmental law. Her work focuses on ensuring the implementation and enforcement of the procedural rights provided by the Aarhus Convention: access to information, public participation in decision-making process and access to justice in environmental matters.


Anaïs has worked for law firms in France and in Belgium, including Huglo-Lepage & Associés, handling issues on a wide range of European law matters including waste, chemicals (including on the REACH Regulation), facilities’ permits, environmental liability and climate change. Before moving to Brussels, she worked as a lawyer for the French Ministry of the Environment, where she focused on Kyoto Protocol and World Trade Organisation (WTO) issues.


She holds degrees in International and European law from French and British universities. She was admitted at the French bar in 2005.

Working at ClientEarth allows me to practise as a lawyer and fight for a cause I believe in at the same time. Ensuring the correct implementation of the Aarhus Convention not only leads to a better protection of the environment and public health but also brings democracy in providing the public with rights that make them part of the decision-making process and in turn make our decision-makers accountable. Aarhus is about enabling the people to make the future their own.
