Humanity’s Ecological Footprint (1961 onwards)
Most of the carbon debate communicates about “global Tragedy of the commons“
Is this a useful perspective?
EITHER: ~ 2°C 450 ppm?
OR: 1700 ppm
Tragedy of the Commons? Yes, but…
X
350 ppm?

Preparing for resource constraints is in overwhelming self-interest of cities and countries. (much more so than for individuals or companies…)
The Ecological Footprint and biocapacity (per capita) of three countries from 1961-2005. A country runs
an
if its Footprint exceeds what its ecosystems can renew. The deficit is made up through net-imports, net-carbon emissions to the global atmosphere, or local resource degradation.

Summary
• The planet has limits. Do you know how much biocapacity you have? and how much you use?
• Blindness costs lives & opportunities.
• Economic stability and competitiveness depends on managing eco-deficits
