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. Speakers: 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.

Anthony Pak, embodied carbon reduction pioneer is joining us today to share his real-world experiences and offer expert insights.

Our industry mostly ignores embodied carbon, even though it will account for almost half of total new global construction emissions between now and 2050. This lecture will provide an overview of embodied carbon in the building industry, including: Importance of embodied carbon Relevant policies and standards Building LCA software tools Embodied carbon of key materials (concrete, steel, wood) Design strategies for reducing embodied carbon Speakers: Anthony Pak, P.Eng., MSc., Principal, Priopta – Life Cycle Assessment for Buildings Dr. Paul Toyne, Practice Leader of Sustainability, Grimshaw An associated Embodied Carbon Workshop with guided discussions and brainstorming on the topic will be held in the afternoon at the Building Energy Exchange (BE-Ex). Organized by AIANY Committee on the Environment

Embodied carbon refers to the greenhouse gases emitted during the lifecycle of a material from extraction through to manufacturing, transportation and installation. In the context of buildings and construction, it is associated with the manufacture of construction materials, the construction process, and even end-of-life demolition and treatment. World Green Building Council (WGBC) suggests that 11% of global carbon emissions are a result of embodied carbon, reflecting its importance in long-term decarbonisation. This webinar drew on local and international expertise to discuss embodied carbon trends and experiences with its management.

He presents his summary of the latest research and information on this topic, which is for a study commissioned by the City of Vancouver. This presentation covers: - What is biogenic carbon, and why is it important? - Overview of how biogenic carbon is addressed in common LCA standards and the latest industry average EPDs for wood products. - How do different WB-LCA software tools (i.e. Athena IE4B, Tally, and One Click LCA) address biogenic carbon? What are the underlying assumptions, and how do they impact WB-LCA case study results? - Introduction to GWPbio, a dynamic approach to modelling biogenic carbon that accounts for factors such as forest rotation period and product carbon storage period. - Presentation of preliminary calculations using the newly released Biogenic Carbon Footprints Calculator for Harvested Wood Products by WWF and Quantis, which builds on the latest research on GWPbio.
