CIRAIG’s brief on the impacts of banning single-use plastic bags in Montreal

As part of the public consultation on the issues and impacts of a ban on single-use shopping bags in retail businesses on the territory of the City of Montréal, the CIRAIG produced a brief to provide its thoughts on the life cycle of shopping bags. These thoughts are both environmental and socio-economic in nature, with the inclusion of social life cycle analysis concepts, and may serve to fuel the debate within the City of Montréal. Since knowledge on the subject is limited, this document provides the avenues of study needed to fully understand the potential impacts of implementing a policy to reduce the use of single-use bags in the Montréal context.

Biomass energy, or bioenergy, is energy produced from renewable biomass, for which the assessment of environmental impacts through life cycle assessment (LCA) presents a number of challenges, in particular methodological ones. The general objectives of this study are to analyze current practices for carrying out LCAs of biomass energy, and to provide recommendations on current and future best practices.

Food choices have a significant climate impact, which can be unknown to the public. The CIRAIG, commissioned by Polytechnique Montréal, has been tasked with calculating the climate-warming impact of the menus offered by the cafeteria, aiming to enable students to understand the impact of their meals and change their eating habits to reduce it.
