Lotte Leicht is a Danish jurist who specializes in international human rights, humanitarian & criminal law, including environmental and climate law, accountability and justice for serious international crimes, and international advocacy.

She has conducted extensive investigations into human rights and humanitarian law violations in conflict zones across the world and has written widely on issues of international justice and human rights. She has led successful advocacy efforts to strengthen human rights protections, secure accountability for serious violations, advance regional and international standard setting, and the establishment of new international, regional, and national mechanisms for justice. She works closely with survivors of atrocity crimes in their pursuit of truth, recognition, reparations, and meaningful justice. Her current work also focuses on documenting the human rights harms caused by climate change, supporting affected communities, and pressing high-emitting states and corporations to reduce greenhouse gas emissions, acknowledge and address transboundary harms, and provide compensation and redress. She is actively engaged in advancing the intersection of international human rights, environmental and climate law, working to protect the rights, lives and livelihoods of present and future generations. This includes promoting both soft and hard law approaches, contributing to jurisprudence, and engaging with national, regional and international courts and mechanisms to strengthen legal accountability and environmental justice.
