Hydro-Québec mandated the CIRAIG’s International Life Cycle Chair to use life cycle assessment (LCA) methodology to study and compare different power generation options, and the electricity mixes* of various Canadian provinces, U.S. states and other countries.
The data on the impact of generating options was collected via a literature review of the LCAs conducted in this field. Over 60 relevant reports or articles, published since 2007, were identified and analyzed. The data gathered was also compared to the data produced by Hydro-Québec.
The data related to electricity mixes came from the ecoinvent database v3.0, which is commonly used to conduct LCAs.
* An electricity mix is the electricity generated by the different types of generating stations that form a network operated over a given territory, and the electricity imported from neighboring territories.
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.
