In 2012's first round up blog, we share a celebratory compilation of our 2011 10:10 highlights, an update on what might be the most exciting week in the life of the Lighter Later campaign to date, and an invitation to Argentina's very first zero carbon festival.

• 2011 was another amazing year for the 10:10 community, and we wanted to do something a bit special to celebrate everything we've achieved together. So we've put together a bumper 2011 roundup page, featuring some of the highlights of the last 12 months. Check it out here.
• Our energy-saving clock change campaign has come a long way, and there's a major milestone coming up. On Friday 20 January, MPs will vote on the most promising clock change proposal for decades. But will your MP be there? Write to them now.
• 10:10 Argentina and Ambientate will be hosting Argentina's first zero carbon festival on 25th and 26th February. The festival is called FestEco and lots of cool things are lined up already: from a bicycle-powered stage and completely green food area, to a massive swap-shop, a fair selling eco-products, information stands, zero carbon educational games, a vegetable patch with urban gardening tips and much, much more. Watch this space for further details.
• Remember 10:10ers Debbie and Mark Griffith who run their own business called Ideal Word? They've just announced a 25% carbon saving. Nicely done!
• Most of you will already know Trevor Payne, director of estates at UCLH and 10:10 pioneer. Not content with inspiring a low-carbon canteen challenge, reducing the impact of UCLH's procurement or tackling energy waste through the Mr Switch it campaign, Trevor is now organising the NHS Sustainability day of action, taking place on 28 March 2012. Check out all the details and register here.
• If you're based in Berlin and keen to make an animation that helps everyone understand climate change, why not contact 10:10 Germany's campaign manager Katie to get involved? Find out more about the project here.
• You should have to have a license to be this cute: “We have the [Solar Schools] website up on interactive whiteboards in the classrooms each morning and the children cheer when they see how well our school is doing.” Check out Get Reading's article about E.P. Collier's fundraising success for their very own solar school roof.
• As if the Yorkshire Dales weren't awesome enough already, they've just announced a carbon emission reduction of 20%. Hats off!
