How socio-economic metabolism can help mitigate climate change

Global Urban Population 2030, will all need stuff

  • Developed world has stuff, don’t need much
  • Developing world is going to need a lot of stuff, driven by population
  • Cities come from large towns, then need a public transport system, which is stuff-intensive
  • Buildings are CO2 intensive

What are chances of realizing a 2-degree target?

  • For 50% chance of a 2-degree target, would require really restrictive policies
  • About 2/3 of emissions are coming from transport, buildings, industry and the use of that stuff

How tight is the carbon budget?

  • A lot of countries have a lot of per capita CO2
  • If we’re going to let less developed countries have transportation, etc., there’s a lot of infrastructural cost, up to 1/3 of the total carbon budget

DI_20150709 033303 ISIE plenary TimBaynes Socio-Metabolic Framework

Socio-economic metabolic framework

  • Aluminum:  a lot of scrap that never makes its way to consumers

Material stocks are not just residual flows

  • Need more information of inputs – outputs
  • Service that stock provides to society?
  • Quality of stock?
  • Material stock for mansion for 2 people is same as for apartment with 6 units
  • A lot of highly depreciated roads that aren’t maintained is the same as a new fresh highway largely used

Controversial:  measuring our physical wealth

  • Good economists don’t measure wealth in terms of flows (e.g. GDP)
  • There’s assets and liabilities
  • Assets have measured wealth
  • In environment science, do measure flows, and have stocks in land and natural resources — but should add fixed capital stock in cities development, not well-developed
