If I bump into Professor Klaus Schwab, who started and still runs the World Economic Forum here in Davos, I will challenge him on the purpose of the event. Schwab has described the WEF as "a platform for collaborative thinking and searching for solutions, not for making decisions."

That's what the impact of two bills recently introduced in the US would be if they, or anything like them, were enacted...

We hope, we wish and we pray that the U.S. team at the UN Climate talks in Durban would set aside its obstructive, destructive behavior. But sadly, listening to U.S. negotiators Pershing and Stern, that is not going to happen. For that reason Greenpeace, WWF, Oxfam and the International Trades...

Of the many things I'd forgotten about my home town of Durban, the one I'm reminded of most often is the humidity. When we were kids here we'd go to discos and be dripping with sweat after a few minutes of dancing. It's...

At the weekend my Twitter feed was alive with news of the hundreds of thousands of people around the world, including in my adopted city of Amsterdam, taking a stand in solidarity with the Occupy Wall Street movement.

This is a profile of one of our staff working in Beijing and his personal journey to becoming an activist that I find truly inspiring:

My name is Tom Wang. Tom is my English name. I gave it to myself when I was learning English from my British teacher. She...

"The idea exists that the ecology movement is a late-blooming fad, something to do with hippies; a fad, moreover, that will vanish the moment serious jobs-versus-nature battles come down in the wake of the first macro waves of recession," wrote Greenpeace founder, Canadian, Bob Hunter, in an unpublished 1990 forward...

Earlier this month, 20 Greenpeace activists were arrested for trying to prevent Scotland's Cairn Energy from its outrageous plan to drill for oil in the Arctic. Sickened by the risks the oil industry is ready to take with our planet, and greatly inspired by the dedication of my colleagues, late...

On June 12 -13, Italians have the opportunity to say "no!" to nuclear power in their country. Berlusconi's government has plans for four new reactors -- but the people have demanded a referendum on the issue of nuclear energy. Surveys show that a majority of Italians are against it; however,...

My guide, when I went to visit Chernobyl on the 25th anniversary of the accident, was a Greenpeace campaigner from Germany named Tobias Muenchmeyer. Tobias is the deputy head of our political unit in Berlin and also happens to know a great deal about nuclear power. But what really registered...
