Organizational involvement
From 1990 to 1995 she served on the board of conservation group Greenpeace International, as well as that of Greenpeace France. George opposed the OECD's proposed Multilateral Agreement on Investment (MAI) in the 1990s, and the ill-fated "Millennium Round" objectives of the World Trade Organization at Seattle in 1999. From 1999 to 2006 she was vice-president of ATTAC France (Association for Taxation of (financial) Transactions to Aid Citizens) and remains a member of the scientific council. She was awarded the title of honorary president in 2008.
George was involved with the World Social Forum since its inception in 2000, and the spin-off European Social Forum. Though she was critical of the forums' initial structure, and believed that more action outside of forums was needed to bring about change, she applauded the steps they made towards changing "the political landscape".
In 2004, she supported John Kerry for president. She canvassed for Kerry in Pennsylvania, but wrote for in a piece for OpenDemocracy "we all thought [Kerry] had a very good chance, even though everyone admitted it was hard to get really enthusiastic about him.... The man isn't the most charismatic ever to walk the earth. But at least he's not a proto-fascist or a go-it-aloner, and that's what we seem—apart from a last-minute miracle—to be stuck with now. With four years clear ahead of him and no re-election to worry about, I fear Bush and the ghastly neo- con/neo-liberals around him will now go on the rampage. They can continue with impunity their attacks on the Constitution and on hard-won freedoms...".
Throughout the latter half of the 2000s, George continued making appearances, such as partaking in the 2006 Table of Free Voices conference, and appearing in the 2008 documentary film, The End of Poverty?.
George was the honorary president of ATTAC France.
