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.

Emission-Chart-r2.png

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.

Embodied Carbon Policy

 

The Toronto Green Standard (TGS) v4  comes into effect on May 1, 2022. As of now, the mandatory tier 1 has no embodied carbon requirements for private buildings, however, the mid-high rise residential and non-residential version's voluntary tier 2 requires the calculation and reporting of the embodied carbon in the building structure and envelope to meet a carbon intensity of 350 kgCO2e/m2, while voluntary tier 3 level requires a carbon intensity of 250 kgCO2e/m2. 

 

The low-rise residential version's voluntary tier 2 requires embodied carbon to be below 250 kgCO2e/m2. Note that all the TGS embodied carbon requirements may be updated based on a number of studies currently underway.


Waterfront Toronto Green Building Requirements v3  requires projects subject to Waterfront Toronto requirements to conduct a whole lifecycle carbon assessment (LCA) during schematic design for the building structure and envelope in accordance with the CaGBC Zero Carbon Building Standard version 2 methodology. In addition, projects are to update at detailed design based on up to date design.

Certification Systems that Address Embodied Carbon

 

LEED v4.1 - New Construction

Through the MRc1: Building Life-Cycle Impact Reduction credit, projects can receive 1 LEED point for conducting conducting a life cycle assessment of the project’s structure and enclosure. Projects can receive up to 3 points if the LCA demonstrates a minimum of 10% reduction, compared with a baseline building, in at least three of the six impact categories listed below, one of which must be global warming potential. Up to 4 points are rewarded for a 20% reduction from baseline along with incorporating reused or salvaged materials into the building design.

 

CaGBC - ZCB Design v3

Zero Carbon Building Standard version 3 requires all project teams to meet a minimum embodied carbon standard of 500 kg C02/m2 or 10% GWP reduction from a baseline building. Two "Impact and Innovation" strategies may be rewarded as higher thresholds of performance.  The two "Impact and Innovation" strategies are:

  1. ≤ 350 CO2e/m2 or 20% GWP reduction from baseline

  2. ≤ 240 CO2e/m2 or 40% GWP reduction from baseline

In ZCB Performance v3, embodied emissions are required to be offset.

ILFI Zero Carbon Certification

Projects must demonstrate a 10% reduction in embodied carbon and not exceed 500 kgCO2e/m2, with remaining embodied emissions offset through an approved carbon offset provider.

ILFI Living Building Challenge - Energy Petal

Projects must demonstrate a 20% reduction in embodied carbon, with remaining embodied emissions offset through an approved carbon offset provider.
