Smiling Sun

The anti-nuclear badge “Nuclear Power? No Thanks" (Danish: Atomkraft? Nej tak.), also known as the “Smiling Sun,” is the international symbol of the anti-nuclear movement. It was ubiquitous worldwide in the late 1970s and the 1980s. BBC News reported in 2005 that few symbols had become "as instantly recognizable across the world.".[1] Even the nuclear power industry recognized the logo's "power and success," the BBC report said. Over 20 million Smiling Sun badges were produced in 45 national and regional languages.[2] In recent years the logo is playing a prominent role once again to raise awareness and funding for anti-nuclear groups, especially in Germany, Austria and Switzerland where opposition is growing to plans for extending operation of old nuclear reactors and constructing new ones.

Smiling Sun Logo (English-language version)

The Smiling Sun logo was designed in 1975 by Danish activist Anne Lund who was part of the Danish organization OOA (Organisationen til Oplysning om Atomkraft [dk]/ Organization for Information on Nuclear Power).[3] By posing the question: “Nuclear Power?” and providing a polite answer, “No Thanks”, the logo was meant to express friendly dissent and - by questioning nuclear power - to stimulate dialogue.[2] In 2011, after the Fukushima disaster, a new version was released for renewable energy, with the statement "Renewable Energy", "Yes Please" (Danish: "Vedvarende Energi? Ja tak!") on a green background with a yellow sun.[4]


The Smiling Sun logo is an internationally registered trademark.[5][6][7] The purpose of the trademark is to protect against alteration and prevent use by commercial and partisan political interests. Anti-nuclear groups may apply for user rights to the OOA Fund in Denmark.[8] An online shop sells Smiling Sun merchandise in 50 different languages.[9] The Italian political parties Federation of Green Lists and Federation of the Greens have licensed use of the symbol for their party electoral materials and logos.
