Background

Nicholas Omonuk is a Ugandan climate justice activist and systems thinker dedicated to building equitable transitions away from fossil fuels and toward sustainable development in Africa.

His work spans international policy advocacy (UNFCCC climate negotiations), community-level climate action (tree planting in 100+ schools), forest protection campaigns (Bugoma & Mabira forests), and opposition to extractive projects threatening African communities (East African Crude Oil Pipeline).

He has participated in major international forums including the European Forum Alpbach and multiple UN climate conferences, bringing Global South perspectives to climate policy discussions.
