As of Oct 1, 2023, the City of Vancouver’s Building Bylaws include an embodied carbon requirement for large (Part 3) buildings. To comply with the requirement, two pathways are possible: the absolute and baseline paths. If choosing the absolute path, the project cannot exceed 800 kg CO2e/m2 (double the benchmark intensity of 400 kgCO2e/m2). If pursuing a baseline path, projects can define a project-specific, functionally equivalent baseline to measure against, and cannot be more than double the baseline. In this webinar, the City of Vancouver and Priopta will present the new VBBL requirement, as well as the guidance provided in the new Vancouver Embodied Carbon Guidelines. The Guidelines cover compliance paths, mandatory and optional element scopes, quantifying embodied carbon, creating a baseline and documentation and reporting requirements.



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.

Zahra Teshnizi, Senior Embodied Carbon Planner

Zahra is a Senior Green Building Planner at the City of Vancouver, where she leads the development and implementation of the City’s embodied carbon policies and initiatives. With over a decade of experience in sustainable and zero-carbon development, Zahra is highly knowledgeable in embodied carbon design, policy, and life cycle assessment (LCA).

In 2017, Zahra led the creation of Vancouver’s embodied carbon requirements under the Green Building Policy for Rezoning, which was the first of its kind in North America. Additionally, she developed a conceptual roadmap for future steps based on the early submissions’ analysis.

Prior to rejoining the City of Vancouver in 2023, Zahra worked as a Senior Advisor at Mantle Developments. During this time, she collaborated with various stakeholders, including developers, governments, and financial institutions, to assess, disclose, and reduce carbon emissions at the building scale. She also played a key role in developing zero-carbon strategies and plans at a portfolio scale.
