What we learned this week

  • The main reason that our carbon emissions have fallen in the UK is that we have exported them to China. But as China becomes a consumer society, where will they export their environmental problems to in turn?
  • The world’s first vertical forest is being built in Milan. Why cover a tower block in trees, other than it being prettier than concrete? Because the trees shade the balconies, aerating and cooling the building. They add humidity to Milan’s dry heat, and they block wind, dust and noise.


  1. I’d bet the vertical forest building will never be built, Would you like to stand underneath it when the wind blows. Much eaiser to plant the whole thing with bamboo or smaller shrubs.
