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.

Taking the message to the Philippines Department of Energy

Mareike, web editor aboard the Rainbow Warrior, give us an update on from the Philippines about how the 'Quit Coal' tour is progressing.

Burning coal accounts globally for over 70 per cent of CO2 pollution from power generation and is the greatest single threat to our climate.

That's why the Rainbow Warrior is on a global tour from New Zealand, via the Philippines and Thailand, to the UN climate panel meeting in Poland at the end of this year, promoting a massive uptake of renewable energy and energy efficiency and the phase out of coal.

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.

A brand new campaign has been launched in which you can Canvass your MP to bring in tougher targets on cutting CO2 emissions. This website was created within a week thanks to climate campaigners working round the clock to make it available to you to take action. The climate change bill proposed by the government promises emissions cuts of just 60 per cent. However, a much higher figure of at least 80 per cent is required for realistically tackling climate change.

Thirty climate campaigners today stopped a coal train on its way to Drax power station in Yorkshire, Britain's single largest source of CO2 emissions. Dressed in white overalls and canary outfits, they used safety signals to stop the train at a bridge on a branch line used exclusively by the power station, before jumping aboard and shovelling coal off onto the tracks. Some used climbing ropes to suspend themselves under the bridge from the train, making it impossible to move the train while the protest continues.

If you thought that the Terminal 5 flashmob and the Big NO! was all that would be done to oppose the third runway then you were wrong. On 3 July, get ready to flashmob once more and launch paper planes at the Department for Transport, and tell transport secretary Ruth Kelly why plans for the third runway must be scrapped.

Download a paper plane here and don't forget to write a message to Transport Secretary Ruth Kelly on it. The plan is to turn up outside Department for Transport (corner of Marsham St and Horseferry Road) at 11am sharp. If you've still got your red t-shirts from T5; even better but a paper plane is an absolute must. At 11.03 (precisely) those wearing ‘Stop Airport Expansion' t-shirts will reveal them, and then we will all launch our paper planes in the direction of the Department.

A few months back when Niall and Jason from Tellyjuice contacted us, they said they liked our videos on YouTube but thought we could be "well, um… funnier". I had to admit that we often forget to see the funny side of things surrounded by all this doom and gloom (did you hear about the bees on the Today programme this morning?!).
