The constant economy

Zac Goldsmith

(Atlantic, £16.99)

Goldsmith, former editor of Ecologist magazine, has developed a theory that “recognises nature's limits” and sets out the details in ten sections ranging from how we can measure human well-being to how we can transform the way we create energy. Some may accuse the prospective Conservative MP of naive utopianism, but the solid breakdown of the possible legislation and tax options keep The Constant Economy very much in the real world.
