The United Nations Environment Programme (UNEP) has been the global authority that sets the environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the UN system and serves as an authoritative advocate for the global environment.

  UNEP’s mission is to provide leadership and encourage partnership 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 works on delivering transformational change for people and nature by drilling down on the root causes of the three planetary crises of climate change, nature and biodiversity loss, and pollution and waste. UNEP employs seven interlinked subprogrammes for action: Climate Action, Chemicals and Pollution Action, Nature Action, Science Policy, Environmental Governance, Finance and Economic Transformations and Digital Transformations.


Increasing use of nuclear power

As of 2021, 32 countries worldwide are operating 443 nuclear reactors for electricity generation and 55 new nuclear plants are under construction. By the end of 2018, 13 countries relied on nuclear energy to supply at least one-quarter of their total electricity. In France, Slovakia, and Ukraine nuclear power even contributes to more than half of the total electricity production.

Nuclear safety is the responsibility of every nation that utilizes nuclear technology. The IAEA, through the Department of Nuclear Safety and Security, works to provide a strong, sustainable and visible global nuclear safety and security framework for the protection of people, society and the environment. This framework provides for the harmonized development and application of safety and security standards, guidelines and requirements; but it does not have the mandate to enforce the application of safety standards within a country.
