July 2025 NGO/Government Roundtable on Embodied Carbon

Andrew Himes – CLF

  • Welcome and introduction to NGO/Governmental Roundtable

    CLF’s Embodied Carbon NGO/Government Roundtable has the following objectives:

    • Share news, strategic plans, resources, and tools related to embodied carbon.

    • Report planning and future dates for conferences, webinars, and meetings.

    • Inspire and facilitate ongoing communication and conversation among key leaders related to embodied carbon.

    • Encourage convergence on shared embodied carbon terminology, data standards, benchmarks, and targets for embodied carbon reduction.

Brook Waldman and Rachelle Habchi - CLF Staff - 2025 CLF Material Baselines

  • 2025 North American Baselines Report was published last month

    • A set of CLF baseline GWP values: estimates of industry-average GHG emissions for construction materials – Primary uses: a basis of comparisons (LEED, policy, project specs, ect…)

    • State of EPD snapshot for North American construction products

    • A supporting methodology – the reader can both see what we did and how we did it, but also can use the methodology for other analyses

  • CLF baselines and their impact

    • Lots of new policies and building codes to provide the current state of the industry that are able to use these baselines (LCA tools, policy, rating systems)
  • What’s new in the 2025 Report?

    • 355 total material baselines with new and expanded product types and categories (compared to 259 in 2023). More industry engagement for the 2025 report, too - created a really great relationship between CLF and industry folks
  • Rachelle: material spotlights

    • Wood: Softwood lumber

    • Wood: Mass Timber

    • Wood: Plywood Panel and Dowel Laminated Timber

    • Ready mix concrete: high strength

Cecilia Wandiga - Center for Science and Innovation

  • Biochar pathway - mixing with concrete and not cement to see where they end up on ratios

    • Combining this as a research project, not just industry, but academia and the general public to share the importance and impact of this mareria

    • Initial test 20% biochar mix → results were flipped from literature, completing further testing

    • Next steps: biochar quality and relevant factors for testing biochar, developing equivalence for the existing International Biochar Initiative scale

  • LEED 4 City CDR Initiative

    • Looking for materials that accumulate in unregulated landfills

    • Sensitivity for those who are vegan, that there are options for alternative waste from slaughterhouse wastes

Ash Lauth - Industrious Labs, Global Cement & Concrete Network

  • Senior Campaign Strategies - Decarbonizing heavy industrial sectors

  • New Global Cement and Concrete Network - inaugural call on Monday

  • State of cement and concrete: emissions in the global south are huge, concrete counts for 8% of global emissions, and a lot of that comes from emerging economies

    • Striking growth in carbon emissions and new cement facilities
  • Lack of advocacy is going on in the global south, and the voices are not heard or represented in the spaces where decisions are being made

  • Advocacy landscape:

    • Policy barriers

    • Global South representation

    • Just transition

    • Fragmented civil society efforts

    • Insufficient resourcing for decarbonization solutions

  • Key challenges

    • Environmental and health impacts of cement in the global south

    • Socioeconomic impacts - economic inequality and vulnerability, barriers to low-carbon solutions, and governance failures

  • Industrious Labs’ co-building and co-creating is aiming to transform the industrial sector by:

    • Building national networks, deepening analysis, harmonizing international and national cement decarbonization solutions, de-siloing key stakeholders, and creating room for diverse perspectives
  • Defining success:

    • Build the capacity of Global South actors to participate and make cement decarbonization a reality in their region

    • Execute sharp analysis and anchor decarbonization in global agendas

Bruce King - Ecological Building Network

Stephanie Dalo - Zero Emissions Innovation Centre, Vancouver

  • Embodied Carbon Awards - really successful event, range of award categories, winners represented lots of sectors in the built environment (development was one which they’ve been working to get more representation)

    • Case studies on their resource library to come!
  • Embodied Carbon Summit - Led by Canadian Green Building Council

    • Lots of industry representation, standardization and harmonization, WBLCA tool alignment, infrastructure and database development to facilitate collection and use of costing data for low carbon building and design, policy and national code, education and awareness, available solutions, roles and responsibilities of industry folks, alignment on political capital
  • CA Board for Harmonized Construction Code - seeking comments on national model codes

  • The Canadian Board for Harmonized Construction Codes (CBHCC) is seeking input on a draft policy direction to address embodied greenhouse gas (GHG) emissions in new houses and buildings through future updates to the National Model Codes: https://cbhcc-cchcc.ca/en/phase-1-embodied-ghg-draft-policy-positions/

    • Requesting data from both the manufacturers and the buildings

    • Initial concepts were presented in a March workshop

      • Manufacturers either report their facility-specific data (energy and material flows) or provide facility-specific EPDs

      • Buildings report basic information and CARB will estimate the emissions or provide a WBLCA

  • CARB staff will be hosting Technical Meetings in September or October this year on the proposed Baseline Methodology and Reporting Requirements and Templates for both building material manufacturers and covered projects. The dates will be finalized with input from stakeholders. We encourage folks to attend and share their feedback.
