Sitting on a train, heading back towards the west Wales sunset after 12 meetings on accelerating sustainability with Do-minded folk in London. There’s a head of steam building that’s going to be driving change sometime pretty soon; here’s a flavour of the conversations:

A business school is looking at putting Social Innovation at the heart of the curriculum, and engaging students in real time problem solving for community and business.

The wonderful Liv Knight, curator of the Challenger Project at Eat Big Fish and doer, is going to host some Do Village events in London to connect Doers with activists who need things Doing.

M&S are one of the world’s leading retailers on the sustainability agenda; I listened to Marc Bolland, the new Chief Executive state his commitment to continue support for Plan A’s actions that he hopes will make the business the world’s most sustainable retailer by 2010. And by the way they’ve invested £200m so far, and gained £250m through reduced costs etc.

Our friends at nef, the New Economics Foundation are developing a lot of interesting projects, including one led by Perry Walker on collaborative consensus building - a pretty essential to navigate the turbulent seas ahead.

Over town to Bloomsbury to catch up with John Elkington at Volans to compare notes on engaging the heart and soul of more employees in organisations that want to to lead the charge.

Up the hill to hear about a project for the action-based Global Cool around the art of conversation

Early morning conversation with John Stone at communications specialists PGI about the scope of using their neat video conference / meetings management tools to help community groups make change happen and gather stories about what works.

Onwards to Euston for an update from Raw TV about their Battlefront project for C4 digital that links Doers with young activists working on anything from bullying and knife crime to wellness and rebuilding community.

Meeting with ecologist, forest and raptor specialist Paul Toyne about developer Lend Lease’s inspirational work on measuring and reducing the ecological footprint of all of the building materials on the sites that they run, and some interesting possibilities to collaborate on biodiversity projects in London.

Then sharing ideas with Tony Manwaring, CX of Tomorrow’s Company about ways of working together to rebuild the USA’s 1939 Futurama’s mission of creating a future that people could see and believe in - then it was about freeways, suburbs and cars - now it’s about wellbeing, nature, carbon and sustainability.

Started out west to Paddington Basin to bounce ideas around with Mike Barry, Head of Plan A for M&S - we’d talked a few times previously about Do, crowd sourcing and Mike had joined us at the first Hay on Earth talks in 2008.

Lastly, a few hundred metres further west at Paddington Station to meet Helen Vincent, daughter of banjo-playing biomimicry guru Professor Julian Vincent. Helen’s running an interesting climate challenge project at the Royal Commonwealth Society that harnesses the egalitarian, voluntary commitment of the 52 Commonwealth members in a commitment to climate that Copenhagen failed to deliver despite resources several orders of magnitude greater.

Back to St Davids for a rest, and maybe a surf if I’m lucky…
