“Organic” model for thinking about material and energy flows in cities dates to 1965 (Wolman, A.)(1965). The metabolism of cities. Scientific American, 179-190.

Beyond VMT in Land Use

In One Project:

VMT related GHG reductions: 46%

Building energy related GHG reductions: 54% (i.e. greater than

the VMT related emissions reductions).

…and this did not include further benefits from embodied GHG

in the improved water and waste systems (often better in infill

locations) or the protected bio-mass sequestered in

undeveloped alternative sites such as prime ag land and

watersheds.

Summary

Quantitative and integrated approach to sustainable

development and design

Outputs for Scope 1, 2 and 3 Carbon emissions classified by

WRI protocol

Outputs for density, waste, energy, water & wastewater

Provides output in non-technical language (marketability)

“How many worlds will an urban future need?”
