International Atomic Energy Agency (IAEA)

"The entry into force of the Paris Agreement on 4 November 2016 marks an important milestone in global efforts to combat climate change.

I congratulate all the Parties for making this landmark agreement a reality. One of the key challenges facing all countries is how to secure sufficient energy to power economic growth, while working to mitigate the effects of climate change. Nuclear power is one of the lowest-carbon technologies for generating electricity. Some 30 countries are already using nuclear power and another 30 are considering introducing it. Nuclear power plants produce virtually no greenhouse gas emissions or air pollutants during their operation, and only very low emissions over their entire life cycle.

Nuclear power has already made a significant contribution to avoiding carbon dioxide emissions and it will continue to do so. The world must not only tackle the causes of climate change. The damage that climate change has already caused to the environment, and the threat it can pose to human livelihoods, also need to be addressed. Nuclear and isotopic techniques make an important contribution to tackling serious environmental challenges such as desertification, soil erosion, pollution and deteriorating water quality. The IAEA is committed to helping its 168 Member States to use nuclear science and technology to generate low-carbon electricity for development, and to counter the effects of climate change."

Yukiya Amano, Director General, IAEA


The Agency shall seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world. It shall ensure, so far as it is able, that assistance provided by it or at its request or under its supervision or control is not used in such a way as to further any military purpose. The IAEA works for the safe, secure and peaceful uses of nuclear science and technology. Its key roles contribute to international peace and security, and to the World's Millennium Goals for social, economic and environmental development.

Reduction efforts

Several measures have been taken, some of them in conjunction with the other Vienna-based UN organizations sharing the Vienna International Centre site.


There are deliberations and measures at various stages of discussion and implementation.
