Globally, the available ecologically productive land area included in the Ecological. footprint analysis is 1.89 hectares for each person. The footprint takes into account fossil. fuel use, cropland, forests, nuclear and hydroelectric power, fisheries and buildings.
Passive heating from the sunspaces had been insufficient. The results show that the average ecological footprint of a BedZED resident is 4.67 global hectares (2.6 planets), which is 89% of the baseline. This would reduce to 4.32 global hectares (2.4 planets) if the energy was all zero carbon.
