Our poles of excellence

The Energy pole of excellence was created in 2018 to consolidate the energy-related knowledge gathered from CIRAIG’s recent LCA studies on electricity generation, natural gas supply chains, liquefied natural gas, natural renewable gas, biofuels, oil products supply chain, coal supply chains, solar PV, wind energy, energy storage systems (hydraulic pump, Li-ion batteries, hydrogen), hydrogen, heating systems, electric passenger vehicles, and marine transports.

  • GHG assessment and comparative LCA analysis of energy sources and energy systems
  • Development of life cycle inventory data
  • Analysis of energy scenarios
  • Return on energy investment (EROI) and documentation of economic indicators (CAPEX, OPEX, and LCOE)
  • Systemic analysis (in development)

The Carbon Neutrality Pole of Excellence aims to develop and structure tools, methods, and data to support organizations of all types in their development of carbon neutrality plans (net-zero) based on proven and robust scientific approaches. Because climate change is the environmental priority of the 21st century, but is linked to impact transfers, the issue of which is crucial, the cluster strives to adopt life cycle approaches – including scopes 1, 2 and 3 – but above all multi-criteria, in order to consolidate truly sustainable carbon neutral trajectories.


Diagnosis and consulting – net-zero trajectories

  • Organizational assessments on scopes 1, 2 and 3
  • Prioritization of decarbonization actions (scopes 1 and 2)
  • Development of green procurement policies (scope 3 upstream)
  • Recommendations for the use of products and services (scope 3 downstream)
  • Evaluation of residual emissions management strategies


Development of internal tools

  • GHG assessment databases
  • Scope 3 reporting calculation
  • Net-zero planning tools


Impact transfer study tool

The Circular Economy Pole of Excellence aims to use life cycle thinking to support the development of a sustainable circular economy. Using tools like Material Flow Analysis, Life Cycle Assessment or circularity indicators, this pole aims to evaluate the performance of circularity strategies.

  • Evaluation of the environmental and social impacts of circularity
  • Perform material flow analyses
  • Measure circularity for a product or an organisation
  • Support the operationalisation of circular economy in a sustainability context
  • Professional training: “Circular Economy and Sustainability Issues”

The Sustainable Consumption pole aims to evaluate the environmental impacts related to consumption behaviours from a life cycle perspective and to identify effective solutions and winning conditions to promote more sustainable consumption. This division covers various consumption sectors such as food, transportation, housing, consumer goods, etc. It is aimed at citizens, but also at the various economic and institutional players and levels of government who wish to make a commitment to the transition to more sustainable consumption. Its main fields of action are :

  • The development of tools to evaluate the environmental footprint of consumption at different scales (individual, municipal, provincial, national)
  • The development of regionalized inventory data sets on consumption
  • Co-construction of solutions with stakeholders to facilitate the transition
  • Raising public awareness and transferring knowledge through various communication channels (e.g. conferences, media, partner networks)

The Agri-Food Pole of Excellence aims to develop skills in the analysis of complex and innovative agricultural systems. It involves systemic coverage of biomass sustainability issues, sustainable food, food system eco-efficiency assessments, the application of advanced tools and methods (SIG, traceability) for the development of data sets and methodologies, communication and dissemination, as well as the participation and involvement in committees, consultation groups, and R&D groups.

  • Study and analysis of agricultural and food production systems and modes
  • LCA and eco-design of agro-food products and bio-based materials
  • LCA of technologies for organic matter recovery, processing and valorization
  • Methodological development for impact assessment
  • External critical review
  • Training in LCA of agricultural and bio-based products
  • Scientific conference and general public conference

The Tools Pole of Excellence aims to create life cycle assessment (LCA) software tools specifically tailored to the needs of clients, to operationalize LCA research in computational tools and to develop a suite of open-source modules that can be assembled to create cutting-edge LCA software tools when combined.

In addition to LCA, the Tools group also uses Input-Output models. The Input-Output (IO) model is one of the core tools of Industrial Ecology alongside LCA. Both methods share common purposes and mathematical backgrounds. IO is a top-down approach while LCA is a bottom-up approach, however. As such, IO offers opportunities that LCA cannot achieve, e.g., a realistic representation of the economy. IO is therefore a much-needed tool when it comes to modeling complete systems and the associated impacts on the environment of these systems.

  • Develop industry-specific LCA software for a client
  • Implement LCA research as computational packages
  • Develop “model explorer” software to allow a client of an LCA to evaluate scenarios beyond the ones initially included in the static LCA report
  • Provide precalculated LCI samples for inclusion in software tools

The Social Pole of Excellence aims to address the potential social and socioeconomic issues of products, sectors and projects using diverse methodological approaches rooted in several social science disciplines. The social responsibility of organizations requires taking into account the social and economic spheres that are organized within the biosphere. Our systemic vision allows us to base strategic decisions on comprehensive sustainability analyses. We can deal with social and socio-economic issues in a multiscalar manner, using methods oriented towards the value chain or in a territorialized manner.

The pole is also developing a fine technical expertise in the analysis of potential social impacts and is participating in the development of standards and best practices in social life cycle analysis.

  • Social life-cycle analysis (S-LCA)
  • Life-cycle cost analysis
  • Corporate social responsibility (e.g. materiality analysis, SWOT, etc.)
  • Assessment of factors influencing user behaviour change
  • Assessment of social acceptability or factors influencing social acceptability
  • Development of decision-support tools (e.g., multi-criteria analysis grid, computational social science, etc.)
  • Valuation and monetization of ecosystem services
  • Stakeholder consultation
  • Training in social LCA

The Sustainable Infrastructure Pole of Excellence aims to implement life cycle thinking for the design of sustainable infrastructure such as carbon-neutral buildings, bridges, roads and other civil and architectural projects. The life cycle perspective is a key element in environmental certifications for buildings (such as LEED or Zero Carbon Building Standard) or Environmental Product Declarations.

  • LCA of infrastructure (building, bridge, road, etc.
  • Development of life cycle inventory data
  • Development of simplified LCA tools for infrastructure
  • Development and revision of methodological guidelines for the sector
  • Professional training: “Life Cycle Thinking and Buildings”

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.

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.

Circular Transition Indicators

Designed for business by business to unleash the transformative power of the circular economy, Circular Transition Indicators v4.0 offers a universal and quantitative framework for evaluating how circular a company is.
