Eco-towns should create situations where residents cut their environmental footprint by two thirds and their carbon emissions by 80 per cent, according to experts consulted by the government.
The new developments should live up to higher standards than are currently being planned, according to the Commission for Architecture and the Built Environment (Cabe) and BioRegional, which is behind a low-energy project in south London.
Homes should be built to high standards of energy efficiency, which will not only cut residents' carbon emissions but also their bills.
Measures such as high levels of insulation and draught proofing should be monitored to ensure that all homes help residents live within the planet's means.
The organisations have called for dwellers in the new eco-towns to consume and emit only what the planet could sustain if the global population lived to the same standards.
Richard Simmons, chief executive of Cabe, told the Guardian: "Eco towns should show us, in a real and measured way, what our sustainable future will look like."
As well as energy efficient homes, residents should own just one car at most per household and use public transport as much as possible.
