This week's been busy for me, what with two demonstrations on two different campaigns. After the protest outside the Japanese Embassy, it was the Department of Transport's turn to welcome us. The government wasn't listening when we said NO to Heathrow's third runway last month. So this morning, we flashmobbed the Department of Transport and launched paper planes saying ‘NO AIRPORT EXPANSION' at transport secretary Ruth Kelly's office.

Art is a great way of campaigning and that's exactly what our EU unit did at the European Commission's headquarters in Brussels today. A 12 metre illegally logged Amazon tree trunk was unveiled, studded with nine video monitors by celebrated Brazilian artist Siron Franco. The monitors drew attention to the trade in illegal timber from the Amazon by displaying images of the rainforest's destruction and also its beauty.

We received an email from Harvey Parkes, one half of the film production company Balti and Havana, promoting their new short Scott of the Antarctics so I'm giving it a plug here. Not merely because they've kindly given Greenpeace a mention at the end (thanks guys!), but because it's a rather gorgeous little piece about penguins, swimming pools and the antarctic ice cap.

It's been entered for the Virgin Media Shorts competition, so if you feel inclined you can cast your vote or just enjoy the film.

It was only my second Greenpeace demonstration after the Big NO to Heathrow's third runway a few weeks back. But this time, we were calling for the release of Junichi and Toru, our Japanese campaigners who are being held in prison without charge for the past ten days and counting. They were arrested for exposing Japan's 'scientific' whaling mission to be a cover up for trade in whale meat. We gathered outside the Japanese embassy with 'Free Junichi and Toru' posters along with a bi-lingual banner with the same message in English and Japanese.

Update July 1 2008: 23 days in custody without charge for Greenpeace Japan activists

Greenpeace supporters gathered outside the Japanese Embassy in London this lunchtime. They held a peaceful protest to express solidarity with the two anti-whaling campaigners currently being held without trial in Japan for their role in exposing a large scale embezzlement scandal within the Japanese government-sponsored Southern Ocean whaling program.

Among the ranks was Greenpeace UK Director John Sauven, who handed in a letter to Ambassador Shin Ebihara asking him to make urgent representation to Prime Minister Yasuo Fukuda for their immediate release, and to order a further investigation into the scandal exposed by Greenpeace.

Offshore wind - 3,500 new turbines by 2020?

Although the PM has taken a few verbal pastings from us over the past few months on key climate issues like airport expansion and new coal-fired power stations, in a new speech today he did much to redeem himself by announcing an ambitious plan to ensure Britain generates 15 per cent of its energy from renewable sources by 2020.

To be sure, the government has promised as much in the past and failed to deliver, but there seemed to be something different about today's Renewable Energy Strategy Consultation - some meat on the bones which indicated that the plan might just be more than empty rhetoric. The government is consulting on ambitious plans designed to allow the UK to meet its share of an overall EU target to generate 20 per cent of energy (electricity, heat and transport) from renewables within 12 years.

This is my first blog from the International Whaling Commission - as I write, we're into the third day of the five-day meeting, at the Sheraton Hotel, in Santiago, Chile. Without trying to justify why it's taken me so long to write something, I would like to explain - despite the fact that not much has happened here so far, it's still been a pretty busy few days.

So, we're here at Glastonbury and, after a few wrong turns on the way here and some hitches pitching my tent (I've never been the best camper), I'm starting to settle into the rhythm of working at the festival.

The Greenpeace field is almost complete and the garden design is quite amazing with covered walkways, vegetable patches and other examples of one planet living. As I write, music is blaring from the skateboard ramp behind me and I can hear the whoosh of wheels as the skaters do their turns.Last night, I was lured into the interactive light installation (another work by Jason Bruges, who created the installation at last year's 100% Light expo) which is quite addictive, especially after a few cans of Strongbow. Watch this video on our moblog to get some idea of what it's about.

With expanded and tougher criteria on toxic chemicals, electronic waste and new criteria on climate change only Sony and Sony Ericsson score more than 5/10 in our latest Guide to Greener Electronics. Nintendo and Microsoft remain rooted to the bottom of the Guide.

The Greener Electronics Guide is our way of getting the electronics industry to face up to the problem of e-waste. We want manufacturers to get rid of harmful chemicals in their products. We want to see an end to the stories of unprotected child labourers scavenging mountains of cast-off gadgets created by society's gizmo-loving ways.

20 Greenpeace activists blocked the entrance to 3 quarries in Normandy that supply concrete and gravel for the European Pressurised Reactor (EPR) site at Flamanville yesterday. We took this action to stop the re-opening of the construction site, which had been ordered by the French Nuclear Safety Agency (ASN). This was despite none of the safety problems the ASN discovered over a month ago having been adequately resolved by EdF, who are carrying out the project.
