Scale of Embodied Carbon Emissions

 

Globally, the building and construction sectors account for nearly 40% of global energy-related carbon dioxide emissions in constructing and operating buildings (including the impacts of upstream power generation). Current building codes address operating energy but do not typically address the impacts ‘embodied’ in building materials and products. However, more than half of all GHG emissions are related to materials management (including material extraction and manufacturing) when aggregated across industrial sectors. As building operations become more efficient, these embodied impacts related to producing building materials become increasingly significant.

Significance of Embodied Carbon

Between now and 2060 the world’s population will be doubling the amount of building floor-space, equivalent to building an entire New York City every month for 40 years. Much of the carbon footprint of these new buildings will take the form of embodied carbon — the emissions associated with building material manufacturing and construction.

 

Embodied carbon will be responsible for almost half of the total new construction emissions between now and 2050.

Unlike operational carbon emissions, which can be reduced over time with building energy efficiency renovations and the use of renewable energy, embodied carbon emissions have irreversibly entered the atmosphere as soon as a building is built.

The City of Vancouver’s Embodied Carbon Guidelines

0:00:00 - CLF BC Intro (Roberto) 0:08:33 - Context (Zahra) 0:15:59 - Embodied Carbon Guidelines Overview (Zahra) 0:31:50 - Q&A Part 1 0:37:52 - Baseline Definition, Modelling Assumptions, Data Collection (Anthony) 1:05:48 - Next Steps (Zahra) 1:11:15 - Key Developments Beyond the City of Vancouver (Anthony) 1:14:23 - Q&A Part 2 Slide Resources: https://clfbritishcolumbia.com/the-city-of-vancouvers-embodied-carbon-guidelines/ 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. 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.
