Lower Don Lands: Climate Positive Candidate
Working with Arup to develop a generic version of the carbon tool that can be more broadly applicable to all Climate Positive Development partners
Hired by WT to calibrate a model for Toronto
Needed a tool to estimate emissions in all Waterfront precincts
Layered-in local transportation options and population’s travel characteristics
Carbon Tool - Partnership based on unique contributions
Provided funding through the Conservation Fund
• To estimate the sustainability performance of urban development projects over a baseline, business-as-usual scenario
• To understand the relationship between development decisions and sustainability
• To explore ways of improving performance by modifying those decisions or introducing new strategies
• To encourage a holistic approach to consider and predict sustainability outcomes

In Sum, the Carbon Tool can be used two ways:
1) To report / monitor a development site and determine existing carbon reductions based on sustainability features of project
2) To guide decisions by exploring potential new sustainability strategies
