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
