I spotted this in the Independent earlier in the week. It looks like the battle for the Eco towns is still on going. The article makes a good point about the true environmental impact on some of the planned towns due to their distance from employment and transport systems.
In principle I am in favour of eco towns, however the plans for the site near Stratford, stuck in the middle of the Warwickshire countryside and no plans to link up the transport system, would mean residents would have to jump in their cars to take their children to school and attend work.
What would make more of an impact would be Eco Developments in cities linked to public transport systems and close to all the services. Otherwise its nothing more than an excuse to build more houses in the greenbelt.
