In communities across the country, we know we need to engage business in the transition to a low-carbon economy. Enter Sustainability CoLab – ambitiously established to meet that need. Since launching in 2014 in response to the success of the Regional Carbon Initiative (RCI) in Waterloo Region, Mike and Priyanka have grown the effort to support organizations in 8 communities across Ontario, which collectively engage more than 150 businesses on climate goals. By 2015, participants had reduced 23,000 tonnes of GHGs per year and committed to reduce over 50,000 tonnes more. Programs now operate in Ottawa, Niagara Region, Hamilton-Burlington, Kingston, Sudbury, York Region, Durham Region, and of course, Waterloo Region.
