Greenpeace campaigners are still in heated discussions this morning with the French government and representatives of other social partners at France's environmental policy making forum, le Grenelle de l’Environnement. If you can read French, keep an eye on the Greenpeace France homepage for the latest updates. If Al Gore is right, this is the beginning of an historic process.

Last night Al Gore joined Nicolas Sarkozy on stage, after the French President announced decisions made during the first two days of the forum, including notably a freeze on GM field trials and a ban on incandescent lightbulbs.

How many years does it take to change a lightbulb? If the lighting industry had their way, it would take until 2019. Sarkozy yesterday agreed to ban the most inefficient lightbulbs by 2010.

France's Environment Minister, Jean-Louis Borloo, said in an interview on Tuesday "if all of France switched lightbulbs, we could save (turn off) a nuclear power station."

There's more stuff in there about the climate and energy efficiency in particular. Indeed, at a glance much of this government's stated Révolution Ecologique (except the nuclear bits for now) looks like Greenpeace's Energy Revolution.

Protests about working conditions in France didn't stop after the original Grenelle (on labour issues) in May 1968. They spread, and inspired more protest and organizing around the world. It's that time again.

(Picture of Rembrandt's Anatomy Lesson is especially for the Dutch Government, which last week U-turned on it's promise to ban the ill-fated incandescent lightbulb.)

UPDATE: The Grenelle is over. La Vie Verte just published a good roundup in English of what happened.
