8
Economic growth climate change
  • Canadell et al. (2007)
  • Since 2000, the factors gt increase in GHGs
  • ? economic growth 65 ( 16)
  • ? carbon intensity 17 ( 6)
  • ? sink capacity 18 ( 15)

9
Economic growth climate change
  • Growth rates in CO2 emissions are increasing
  • 1990s 1.3/year
  • 2000-2006 3.3/year

10
Economic growth climate change
  • CO2 concentrations 1.93 ppm/year
  • highest rate on record

Climate change biodiversity loss
  • IPCC AR4 (2007)
  • recent warming is already strongly affecting
    natural biological systems
  • Observed changes
  • species ranges
  • phenology
  • habitat loss

14
  • Projected impacts
  • Most vulnerable terrestrial ecosystems
  • virtually certain (gt99 probability) to
    experience severe impacts
  • Endemic species are the most vulnerable

15
  • Projected impacts
  •  
  • High confidence (80 chance)
  • 30 increase in risk of extinction with 1 C
  • gt40 with 4 C warming

16
  • How to limit growth ethically?

17
Ethical principles
  • Polluter Pays
  • Common but Differentiated Responsibilities
  • Ability to Pay
  • Basic Needs

18
Ethical postulates (Shue 1999)
  • If climate change costs are imposed on the South
    without their consent by industrialized countries
    in the North, then the South has the right to
    demand the North shoulder the burdens of
    mitigation and adaptation.
  • - polluter pays
  • - common but differentiated responsibilities

19
Ethical postulates
  • 2. The North should contribute more to mitigate
    climate change because it has the most resources.
    This position is logically irreducible.
  • - ability-to-pay
  • - common but differentiated responsibilities

20
Ethical postulates
  • 3. With unequal capacity to mitigate and adapt to
    climate change, the South should at least be
    guaranteed an adequate minimum to meet basic
    needs. An adequate minimum guarantee requires a
    right to development if such a minimum has not
    been achieved.
  • - basic needs

21
Framework
  • Per capita GHG emissions
  • Cap-and-trade
  • 1. set a cap
  • 2. allocate credits
  • 3. determine trading rules
