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.

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.

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.

The folks behind the 350 campaign have just launched a brand new website: 350.org with an amazing video that spells out what 350 parts per million is about in 90 seconds without using a single word.

No one will be surprised that Greenpeace is against the construction of new nuclear power stations, but what some may find unusual is one of the solutions we are proposing to meet our energy needs and reduce our CO2 emissions - industrial CHP, or combined heat and power.

Hot on the heels of Friday's 'Great coal train action' which halted coal shipments to Drax power station for the best part of two days, comes news of more anti-coal activity. Early this morning climate campaigners from 'Leave it in the Ground' occupied UK Coal's Lodge House site in Derbyshire where a new open cast coal mine is planned, and the rural lanscape is about to be devastated by huge earth-movers.
