Anne-Marie Klijn has practised law since 1990 and advises companies and public authorities in all areas where national and local government exercise direct influence on society. This included aspects such as spatial planning, the environment, nature, energy, water, traffic and transport, subsidies and grants, education, health care, government liability, loss resulting from government planning decisions and compensation for loss resulting from administrative acts, for instance. She focuses particular attention on sustainability and circular building. The energy transition and its impact on the global ecosystem must inevitably be part of considerations on the acceptability of a project from an environmental law perspective. Anne-Marie also worked as a municipal lawyer for the Municipality of Amsterdam between 2015 and 2019.
