One of the most challenging weeks of my working life starts today: the week of the Annual Meeting of the World Economic Forum (WEF) in Davos.

Over 2,500 Presidents, Prime Minsters, CEOs, Celebrities and Academics with a smattering of civil society, will be holed up in...

"What counts in life is not the mere fact that we have lived. It is what difference we have made to the lives of others that will determine the significance of the life we lead." -- Nelson Mandela speaking at the 90th birthday celebration of Walter Sisulu, Walter Sisulu Hall,...

There's a clear parallel between the behaviour of the fossil fuel giants and tobacco companies: tobacco companies went to extraordinary lengths to suppress the knowledge that smoking caused cancer, activities that eventually resulted in multi-billion dollar settlements.

Today, some fossil fuel giants engage in similar tactics to

If it's wrong to wreck the planet, then it's wrong to profit from that wreckage.

We are facing a planetary emergency: Climate change threatens the world and our collective future. Business and political leaders know this yet they do nothing. Instead they continue to bet on...

This week, in New York, countries across the globe are meeting at UN headquarters to negotiate the next steps towards high seas protection. Unless action is taken by governments to restore and protect the health of our oceans, our oceans will be unable to sustain life on Earth.

Un événement inattendu est survenu mercredi soir. La compagnie pétrolière Shell a temporairement interrompu ses forages au large de l'Alaska, reconnaissant qu'il est impossible d'y agir de manière sécuritaire et laissant un an de répit aux habitants de la région.

Cette firme, qui possède l'un des pires bilans au monde...

An unexpected thing happened last night: One of the biggest oil companies in the world -- Shell -- made a big decision acknowledging that the oil industry cannot operate safely in the Arctic. A decision that means one year of relief for the people and wildlife of the Arctic.

Shell,...

No one likes to be "unliked" on Facebook or elsewhere. But, every year for the last 12, I put on a brave face and go where I must -- not where I like -- where the world's most powerful people are: Davos, the World Economic Forum (WEF). Every year, I...

Dear Mr. President,

My Name is Kumi Naidoo, I am the Executive Director of Greenpeace International, I also serve as President of the Global Campaign for Climate Action (www.tcktcktck.org) and serve as Global Ambassador of the Global Call to Action Against Poverty (www.whiteband.org). But, today I...

Shocking is the only way to describe the extraordinarily cynical comments made to the Financial Times (November 4, 'Global Warming: Climate change needs action but it has a cost') by Milton Catelin, chief executive of the World Coal Association, in trying to downplay any idea that climate change...

I felt relieved when I heard Obama's victory speech this morning, and I particularly resonated with him when he spoke about the future of America's children.

"We want our children to live in an America that isn't burdened by debt, that isn't weakened by inequality, that isn't threatened by the...

Ecological and economic welfare are two sides of the same coin and having to choose between developing economies and societies on one hand, and protecting the environment on the other, is a false dilemma. This false dilemma is often used by private companies to dismiss civil society and local communities,...

When I spoke to my friends and family this weekend I was unanimously scolded. After Friday's 15-hour occupation of Gazprom's Prirazlomnaya oil platform in the Pechora Sea, they all said "you're getting too old for this!" With blue hands and feet from the...

This November marks three years since I was appointed Executive Director of Greenpeace International. Coming to Greenpeace represented an opportunity for me to actually be part of an organization that has taken, and continues to take a leadership role in warning about the dangers of environmental destruction and climate change.

There are certain iconic moments that prove to be turning points in history, where the momentum swings towards change.

These are marked by symbolic events that crystalize public opinion, influence investor sentiment or lead to political upheavals.

The financial crisis in 2007-08 that ushered in policy change to limit investment...

Yesterday in Amsterdam, I was served with an urgent notice from Shell, one of the world's wealthiest oil companies, who in the past weeks we have been vigorously and prominently campaigning against in our Save The Arctic drive. The notice was a stern message from Shell lawyers, who are very...

I was recently humbled to accept an invitation from UN Women Executive Director, Michelle Bachelet to join her Global Civil Society Advisory Group. In reflecting on the appointment, I'd like to call to your attention the passionate environmentalist and politician Wangari Mathaai.

It's almost a year since Wangari's passing; I...

We're at a critical stage in our journey as activists. As a movement we're easy targets, and we've endured all manner of strife along the way. Today in many countries we face serious political and legal challenges, designed to punish and discourage dissent; designed to have a deliberate 'chilling' effect....

The Internet and social media are extraordinary engines of change helping to drive revolutions and positive social change. They've become central tools for how we put pressure on polluters and governments. But if we are not careful, the Internet could become an internal combustion engine that fuels climate change instead....

What would you do with $1738 billion (U.S. dollars)? If you were told you had to spend it this year on making people safer, what would you spend it on? $1738 billion is how much was spent on the world's military last year, according to estimates by the...
