The GLH volunteer movement was started in 2011 by Nassrine Azimi of UNITAR and Tomoko Watanabe of ANT-Hiroshima, and it aims to disseminate the universal message of Hiroshima and Nagasaki, by sharing worldwide the double message of caution and hope that the survivor trees of Hiroshima represent, recalling the dangers of arms of mass destruction and nuclear weapons, as well as the sacred character of mankind and the resilience of Nature.

Some 170 trees of about 20 different species, in 55 locations within the roughly 2km radius of the hypocenter of the Atomic Bomb, are officially registered by Hiroshima Municipality as A-bombed trees. Lovingly cared for over the years by ordinary citizens, they are identified by all as "hibakujumoku" survivor trees. The Ginkgo biloba sapling that was planted today is a direct descendent of one of the oldest living trees in Hiroshima’s historical Shukkeiin Garden.

Currently seeds and saplings from Hiroshima’s A-bombed trees are being raised by GLH partners in some 30 countries.  Mayors for Peace, the Secretariat of which is in Hiroshima, has joined the movement, and is actively seeking the engagement of its more than 7000 member cities in the survivor tree planting campaign, for a vision of a nuclear-free and more ecological planet.
