Based on the notion that CO2 is destroying the planet, should you build a new town in open countryside?

Eco-Towns Fail Carbon Neutral test : Red, Green, and Blue

Because, as well as taking up open countryside, they allow developers to limit environmental innovation to these smaller projects, instead of spreading it through all new housing, and they will be net generators of greenhouse gases according to the Town and Country Planning Association (TCPA) which is advising the British government on the concept. The towns will, according to the TCPA generate much less greenhouse gas than other forms of settlement but ‘to call it zero-carbon is slack language.’ And if the new eco-towns can’t manage to be carbon neutral, then that means that by 2020, there could be 3 million new carbon-emitting houses in the UK.
