To encourage further discussions at UN headquarters about the human right to a clean, healthy, and sustainable environment, including its merits for people and planet, and to take forward the Council’s invitation that ‘the General Assembly […] consider the matter’, on 12 April UNEP, the Universal Rights Group, the UN Special Rapporteur on human rights and environment, New York University, and others, will convene an expert seminar to consider developments to-date, discuss key issues and questions (including legal questions) related to the right to a healthy environment (including those posed during negotiations over resolution 48/13), look ahead to possible GA recognition and what it would mean, and reflect on the benefits of recognition for individual rights-holders around the world, including EHRDs, as well as for the natural environment (including addressing the three interwoven crises of biodiversity loss, pollution, and climate change).
