This morning, starting at  5.30am, teams of Greenpeace volunteers have been shutting down BP stations across London. We aim to close dozens down this morning.

Watch the action as it happens - pictures, video and text updates from the teams.

The teams - each named after an animal threatened by BP's reckless oil exploration - fanned out across the capital in their electric and hybrid cars, going station to station and disabling the pumps.

Why today? Because BP is expected to announce later the appointment of Bob Dudley as the company's new head to replace the gaffe-prone Tony Hayward, who led BP during the disastrous Gulf of Mexico oil spill.

Our colleagues in the US have been blogging regularly about the ongoing disaster in the gulf and Greenpeace's involvement in the response to the oil spill. Here, Mike Gaworecki sheds some light on the clean-up operation BP has been carrying out on its image.

There's no way to clean up an oil spill. We've seen this time and again - in Alaska's Prince William Sound, for instance, where oil from the Exxon Valdez spill is still having an impact on local ecosystems. Corporations like Exxon or BP that find themselves responsible for an oil spill - or, as was the case for Exxon and now is the case for BP, an oil disaster - are really left with only one option to handle the problem: public relations, damage control and fierce lobbying.

All is not doom and gloom in Brazil. The soya moratorium, which Greenpeace helped establish in 2006, has been renewed for another 12 months, which means another year of soya traders refusing to do business with farmers growing crops on newly deforested land. In addition, companies like McDonalds, Sainsbury's, Waitrose, Marks & Spencer and the Co-op have reaffirmed their commitment to the moratorium, ensuring that they continue to demand non-Amazon soya at the consumer end too.

There's no denying that the moratorium has been a success. Since it was established four years ago, deforestation rates in the Amazon have decreased while soya yields have increased, showing that (as Paulo Adario from our Brazilian office put it) "production and conservation can go hand in hand".  

With last year's agreement between three of the largest slaughterhouses in Brazil to prevent cattle ranching making further in-roads into the rainforest, we've made great strides in breaking the link between agricultural production and deforestation. But the current attempts to change the forest code could undo much of the success of recent years so there's no rest for the wicked just yet.

While the EU has just voted to ban illegal timber, yesterday Brazil came a step closer to severely weakening the forest code which has helped protect the Amazon rainforest for over 70 years. The Brazilian congress approved the plan to amend the legislation, and if it becomes law then the area of the rainforest which can be legally destroyed will dramatically increase.

Paulo Adario and others from our Brazilian office were present and activists protested against a yes vote. There was also plenty of criticism from other concerned parties - environmentalists, rural organisations and legal representatives, for instance - but still the vote passed.

The amended forest code still has to pass several more hurdles before it reaches the statute books, but with each yes vote it becomes more and more likely it will do so. Eventually, it will have to go to the president who can sign it into law or kick it out. Hopefully it won't get that far, but we'll let you know how you can help if and when the time comes.
