The Global Council for Science and the Environment (GCSE) is a nongovernmental organization established in 1990 that advances the use of science to inform environmental decision-making. The work of GCSE spans boundaries between science and decision-making to strengthen the impact of durable solutions to environmental challenges. GCSE engages scientists, educators, policymakers, business leaders, and officials at all levels of government. GCSE was formerly the National Council for Science and the Environment (NCSE). Learn about our mission and approach.
