Since 2015, Karen has supported several municipalities in developing community energy and emission plans (CEEPs) to reduce energy consumption, emissions, and costs. Partnering with York University colleagues, she has worked with over 70 municipal planners in Ontario and New Brunswick to promote the integration of climate and energy policies into land use planning. Recently, Karen’s focus has transitioned to implementation with several innovations in governance, retrofit business models and municipal secondary planning. Her work on energy transition governance contributed to the establishment of organizations in Brampton, Oakville and Durham Region dedicated to sustaining CEEP implementation. She collaborated in the development of energy and climate policies for Brampton’s Heritage Heights Community, a net-zero development housing approximately 124,000 people and 43,000 jobs.
