The United Nations Environment Programme (UNEP) is the leading UN body responsible for coordinating global efforts to protect the environment and promote sustainable development. Established in 1972 following the landmark Stockholm Conference on the Human Environment, UNEP is headquartered in Nairobi, Kenya, making it the first UN body to be based in a developing country. Its mission is to provide leadership and encourage partnerships in caring for the environment by inspiring, informing, and enabling nations and peoples to improve their quality of life without compromising that of future generations. UNEP plays a central role in setting the global environmental agenda, conducting research, and offering guidance to governments and organizations on issues such as biodiversity, climate change, pollution, and the management of natural resources.

UNEP is also the driving force behind several important international environmental agreements, including the Montreal Protocol, which successfully phased out ozone-depleting substances, and the Minamata Convention on Mercury. It supports countries in implementing the Paris Agreement on climate change and works closely with the Intergovernmental Panel on Climate Change (IPCC) to provide scientific assessments. Through initiatives like the Global Environment Outlook and the Emissions Gap Report, UNEP delivers authoritative data and analysis that shape policy decisions worldwide. In addition, UNEP helps nations build capacity for sustainable practices by promoting renewable energy, waste reduction, and green technologies. It also engages in raising public awareness about environmental issues and fostering cooperation between governments, civil society, and the private sector. Despite challenges such as limited funding and the scale of global environmental crises, UNEP continues to advocate for collective action, equity, and innovation, emphasizing that a healthy environment is essential for peace, prosperity, and human well-being.
