Updated facility‐level inventory and LCIA of the public electricity grid in Ontario, Canada
The Canadian Journal of Chemical Engineering, EarlyView.Abstract As the composition of Ontario's electricity grid will change over time, it is important to have a comprehensive understanding of the environmental impacts of Ontario's electricity grid as it stands today. However, publicly available information on impacts of Ontario's electricity grid is available only in aggregate from government sources.
