Aug. 8th - BC Embodied Carbon Modelling Study

Join us for the first public presentation of the “BC Embodied Carbon Modelling Study”, which was developed for the BC Provincial Government by Priopta with support from Mantle Developments. This event will cover a wide range of important topics relevant to the future of embodied carbon policy and action in BC.


Event Outline:

Zahra Teshnizi (Senior Advisor to Mantle Developments) - Introduction (10 minutes)

  • Introduction to this study

  • High-level overview of embodied carbon policy tools

  • Design & Procurement

  • Manufacturing & Importing

  • Zero Waste & Circularity

Anthony Pak (Principal at Priopta) - Presentation (90 minutes)

  • Why BC needs to develop bold Provincial embodied carbon policy

  • Projected total embodied carbon associated with new construction in BC (2020-2050), based on our modelling utilizing best available embodied carbon benchmark data

  • How BC’s total annual embodied carbon compares with various relevant sectors reported in BC’s Provincial GHG Inventory, including operational carbon

  • Multiple Whole Building Life Cycle Assessment (WBLCA) Case Studies of detailed buildings representing various building archetypes, exploring strategies to reduce embodied carbon to various % reduction thresholds

  • Cost impact of reducing embodied carbon, based on relevant published information Proposed % reduction embodied carbon thresholds that could potentially be integrated into a provincial policy framework

  • Consumption-Based Emissions vs Production-Based Emissions, Carbon Border Adjustments, and proposed methodology for using trade data to support such policies

  • Forestry and Biogenic Carbon Accounting - Exploring the latest developments in biogenic carbon accounting methods such as GWPbio (stand-level) and A0 (landscape level), and how such assumptions could impact our LCA calculations

Question and Answers (20 minutes)


Zahra Teshnizi (Senior Advisor to Mantle Developments) Zahra is a Senior Advisor at Mantle Developments and the co-chair of CLF Vancouver. At Mantle, she leads projects that support developers and policymakers in assessing and minimizing carbon emissions of buildings and developing decarbonization strategies, focusing on embodied emissions. Before joining Mantle, Zahra worked at UBC, where she managed various research and educational projects studying innovative low/zero-carbon building solutions and policies. Zahra’s contributions to shaping the embodied carbon discourse in Canada include developing the first embodied carbon requirements for the City of Vancouver's rezoning bylaw.

Anthony Pak, Principal at Priopta and CLF Global Hub Director Anthony is the Principal at Priopta, a firm with deep expertise in Life Cycle Assessment (LCA) for buildings. Priopta supports design teams in reducing embodied carbon on construction projects and works with leading organizations and jurisdictions to develop effective embodied carbon policies. Anthony is also the founder of CLF Vancouver—the first local hub of the Carbon Leadership Forum—which organizes local events that empower industry professionals to radically reduce embodied carbon from buildings and infrastructure. Since 2019, CLF Vancouver has inspired over 30 other cities to start CLF local hubs. He now also serves as the CLF Global Hub Director, working to support the growth and impact of CLF hubs around the world.
