The Institut national de santé public du Québec (INSPQ) decided to draw on the expertise of the CIRAIG to conduct a life cycle assessment (LCA) of ten urban heat island mitigation (UHI) measures applicable to the residential sector. The goal was not to compare or evaluate the effectiveness of these measures, but rather to assess the other potential environmental impacts that result from their implementation and maintenance during a specified period. The options were therefore analyzed on an individual basis (implementation of a particular measure), without taking into account their temperature reduction potential.
This assessment was intended to:
This study was carried out in accordance with the requirements of International Standards ISO 14040 and 14044 for a LCA disclosed to the public and including a comparative assertion. It should be noted that this study was critically reviewed by a panel composed of a LCA expert and specialists in the fields involved in the study.
In Life Cycle Assessment (LCA), the accounting of biogenic carbon is little harmonized. Different, even contradictory, approaches are identified in current standards for different sectors of the economy (biofuel, bio-based plastics, construction, etc.). The general objectives of this study are to identify the issues at stake in these approaches, in order to issue recommendations for several actors.
Open source Input-Output LCA model and tool to estimate life cycle impacts of products and services
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.
