As more emphasis is placed on fostering a green economy, large businesses are investing in new ways to power their operations with renewable sources. 

GM Canada is one such business. In August 2020, the company announced it had completed a $28 million cogeneration project that uses renewable landfill gas (LFG) from a local landfill to power and heat its St. Catharines, Ont., Propulsion Plant.

Carolyne voiced her support and the two companies, along with their partner, Integrated Gas Recovery Services (IGRS), began planning the project. The partners ultimately agreed to build a 3.3-kilometre-long pipeline to carry the LFG from the Walker landfill to GM Canada’s plant.
