introducing GHGProof…

What is the purpose of the model?

what land use aspects are captured?

how can it be used?

What is the process?

what do the results look like?

a pioneering, innovative decision-making tool to enable planning processes to

include GHG emissions impacts

aspects not included

buildings

• industrial uses

• embodied energy

• micro energy generation

transportation

• modal shifts to cycling

• commercial transport

• transport of waste

• trips outside municipal boundary

• air and water travel

waste

• construction for sewer extensions

possible uses

assess community/regional plans

set a GHG reduction target

develop policy to achieve target

future proofing

evaluate development proposals
