Messages from the Director General

"Climate change is the biggest environmental challenge of our time. More and more countries are using nuclear technology to combat climate change. Nuclear power is an important source of clean low-carbon energy and has a significant role to play in reducing greenhouse gas emissions. Nuclear science also provides valuable data that help scientists to better understand climate change so that policymakers can make the right decisions. In addition, many non-power applications of nuclear energy help countries to adapt to some of the consequences of climate change which the world is already facing.”

Cornel Feruta, acting Director General



The International Atomic Energy Agency is an independent intergovernmental, science and technology-based organization, in the United Nations family, that serves as the global focal point for nuclear cooperation; assists its Member States, in the context of social and economic goals, in planning for and using nuclear science and technology for various peaceful purposes, including the generation of electricity, and facilitates the transfer of such technology and knowledge in a sustainable manner to developing Member States; develops nuclear safety standards and, based on these standards, promotes the achievement and maintenance of high levels of safety in applications of nuclear energy, as well as the protection of human health and the environment against ionizing radiation; verifies through its inspection system that States comply with their commitments, under the Non-Proliferation Treaty and other non-proliferation agreements, to use nuclear material and facilities only for peaceful purposes.

Experience so far

Greening the General Conference

The 63rd IAEA General Conference is going green. To demonstrate its commitment to sustainability, the IAEA will organize the conference as a green meeting according to the guidelines of the Austrian Ecolabel. This means that the IAEA will keep the ecological impact of the General Conference as low as possible. The Vienna International Centre is already a workplace that is powered by carbon neutral electricity from 100% renewable sources. There will be a focus on the areas of paper smart documentation, waste reduction and recycling, and environmentally friendly catering.

The IAEA as organizer will contribute to making the General Conference a Green Meeting. Delegates can have a role in this endeavour and are encouraged to choose environmentally friendly options when planning their participation. Small actions can make a big difference: choosing environmentally certified accommodation, giving feedback via the IAEA Conference and Meetings app, sorting waste for recycling, and returning name badges - these will all help to reduce the environmental impact. Information on how to effectively contribute to climate protection, both locally and globally can be found here.

Vienna has an efficient network of public transport - buses, trains, trams and underground lines - that covers most of the city. The IAEA encourages participants to make full use of these greener modes of transportation.

EMS and reduction efforts


A draft EMS has been produced



Following on from the Vienna International Centre carbon neutral facility in 2016, the Agency has off set 100% of its emission of since 2015

Offset in 2017 was for 27,990 tons of CO2

Waste and water management


In partnership with the other Vienna Based Organisations located at Vienna International Centre, as a common services UNIDO – Building Maintenance Services takes the lead.

Next steps


IAEA plans on introducing an environmental management system (EMS).
