ommunities increasingly address climate change through local government policies and actions. Sustainability Solutions Group (SSG) is further supporting these efforts with the release of GHGProof - a powerful yet easy to use, fully transparent and open source model that enables local governments to measure greenhouse gas emissions (GHGs) and costs ($) resulting from potential land use policies.

Jesse Dill Ghg Proof May28th

  1. 1. GHG MODELING TOOL: EVALUATION OF THE IMPACTS OF LAND USE DECISIONS ON GHG EMISSIONS Jesse Dill – Associate Member Sustainability Solutions Group
  2. 2. land use-GHG connection building form energy supply land use changes 24,711 tC02e transportation behaviour 30 hybrids for LED street waste city staff anti-idling carbon lights campaign offsets local agriculture energy- plant 5000 efficiency trees education car pooling program
  3. 3. introducing GHGProof… a pioneering, innovative decision-making tool to enable planning processes to include GHG emissions impacts 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?
  4. 4. aspects of GHGProof buildings residential personal emissions transportation agricultural solid community-wide GHG emissions waste liquid agriculture absorption biomass forest
  5. 5. 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
  6. 6. possible uses assess community/regional plans set a GHG reduction target develop policy to achieve target future proofing evaluate development proposals
  7. 7. modeling process building a scenario
  8. 8. modeling process GIS analysis to assess land use pattern
  9. 9. modeling process GIS analysis to assess VKT GHGTRANSPORTATION = (average trip length)(total # of trips) (% of trips by vehicle)(emissions factor) Longer VKTs in rural areas Shorter VKTs in urban areas
  10. 10. modeling process excel-based calculator e.g. building form calculation automatic calculations Buildings (tC02e)= real time changes (# of buildings by type)* rapid generation of (energy per area)* scenarios (emissions factor )* (average floor area)/ 1000 kilograms
  11. 11. model results detailed and summarized results Transportation Trip length tCO2 0 detailed impacts of Mode shift 0 Public transport Sub-total 0 0 each variable on GHGs % of Total 0% total & per capita GHG Road Road length, asphalt 0 Road length, gravel Sub-total 0 0 emissions summary % of Total 0% chart generation Buildings Process energy 0 Community energy 0 Sub-total 0 % of Total 0 GHG (tC02e) Waste Solid 0 Liquid 0 Sub-total 0 % of Total 0% Biomass Agriculture- local food 0
