Open source Input-Output LCA model and tool to estimate life cycle impacts of products and services

OpenIO-Canada is a Canadian Environmentally Extended Input-Output (EEIO) model. It describes the Canadian economy in 13 provinces and territories, 492 commodities, 33 GHGs, around 300 pollutants in 3 compartments (air, water and soil), 67 mineral resources, water consumption, energy use and plastic waste pollution. The model reliably covers emissions and economic transactions from the years 2018 to 2020. An update of the model, integrating the latest available data, is made around the end of each calendar year.

The international trade of each province is covered within the openIO-Canada model through the use of the EXIOBASE EEIO model. Cars imported from the US for instance, are thus modeled with the description of the American economy, as depicted in the EXIOBASE model, instead of assuming that these cars are produced as they would be in Canada.

The openIO-Canada model supports the endogenization of capitals. Emission factors from the database thus correctly include capital goods within the scope of their assessment. These goods are typically excluded from emission factors provided by non-capital-endogenized versions of EEIO models.

The openIO-Canada model can be used to provide emission factors (/$) on 6,396 commodities produced across Canada and 9,600 commodities produced outside Canada. It can also be used to determine different environmental impacts for each province or Canadians overall. For instance, the average carbon footprint (following a consumption approach) of a Canadian in 2020 was around 16.2 tCO2eq while the same footprint for a Quebecer was around 12.1 tCO2eq. An average 6.7% decrease was observed between 2019 and 2020, most likely due to the COVID19 pandemic.

The openIO-Canada model is open-source and free. You can generate all the data yourself through this Github repository.

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.
