Ecological Debt Day
Global Ecological Debt, also
known as overshoot
1.0
We have been in
Global Overshoot
since 1987
We go into Overshoot for a particular
year on Ecological Debt Day, and for
the rest of that year our consumption
adds to our global Ecological Debt. Our
overshoot is currently 30%, or 1.3
planets worth of biological capacity.
