The Urban Stack

  • 1% (ONE) of the world surface is built up (with 50% of land used in agriculture to support the majority of people in that 1%)
  • Half the world population already lives in urban environments, 2/3 by 2050 (with the US at 89%, China at 80%). Play with these interactive graphs for insights.
  • The urbanization of the world will be driven by “emerging” (and currently less urbanized) countries, with three cities in China (Chongqing, Beijing and Shanghai at or above 30m inhabitants by 2030!)
  • The top 750 cities by 2030 will generate 61% of the world GDP ($80 Trillion) and 55% of global consumer spending ($40 Trillion)
  • But according to intercity-alliance C40, large cities consume 2/3 of the world’s energy and create 70% of global CO2 emissions.
  • This does not include the amount of resources (and emissions) that was required to build those cities up. Concrete alone generates 8% of global CO2 emissions (3x more than aviation)…
  • …or Steel which generates another 6.5–8% of annual CO2 emissions. In aggregate buildings generate more than half of total greenhouse has emissions.

  • And as an industry it’s huge with PWC estimating global real-estate in 2020 to surpass $45 Trillion
