• Is the alternative for more people to live in London?

    Yes. The closer we live together , the more efficient all our services are, the closer we are to shops and culture, the less transport we need, and of course the fewer cars. Urban living is green.

  • More competition for accommodation, higher cost of living, fewer green spaces. A push towards increased urban living is unsustainable.

  • If we are talking about "green" as in environmentally better for the planet/population as a whole, @william. is right. As the population grows, (good) urbanisation is much more sustainable than filling up the the countryside with individual houses and roads and carparks and shopping centres etc.
    Still need better bike provision on trains though!

  • "every 1% increase in the population density of a city associates with a 0.79% reduction in its CO2 emissions per capita"
