LOW CARBON NOW | CLF Toronto Event

LOW CARBON NOW | CLF Toronto Event

The climate emergency has been declared. The World Green Building Council has stated that all new buildings are to be net zero operational carbon with a 40% reduction in embodied carbon by 2030. But, what can we do NOW to get there? We know that the decisions we make today will impact the carbon footprint of the buildings we design for their lifetime and we know that high performance buildings will play a significant role in the transformation to a low carbon economy. In Toronto, buildings account for about 60% of all carbon emissions and of the 323 cranes in the air, the vast majority are for residential projects - far more than any other North American city. Unfortunately, residential buildings have been the slowest to make the move toward low carbon design principles, so we wanted to see what could be done to change that. As key stakeholders in the development of residential buildings in Toronto, we want to understand why change is so slow, how we can come together to do something about it and ultimately aim to design buildings that are both affordable and sustainable. This presentation covers multiple insights on how we can get residential buildings down to net zero carbon. With the designer, developer, and contractor perspectives, we present a full picture of the opportunities and challenges to successfully plan, design, and build lower carbon residential buildings in Toronto based on a case study completed by a multidisciplinary team of people focused on low carbon solutions.

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.

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, while voluntary tier 3 level also requires a 20% reduction in embodied carbon against a baseline building. 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's Minimum Green Building Standards  also requires the calculation and reporting of embodied carbon.

Certification Systems that Address Embodied Carbon


LEED v4.1

Through the MRc1: Building Life-Cycle Impact Reduction credit, projects can receive 1 LEED point just for performing an LCA study and up to 5 points for a 20% reduction in embodied carbon relative to a baseline building. 


CaGBC - ZCB Design v2

Requires calculating embodied carbon emissions through an LCA study starting at the Schematic Design phase. Also required to apply two "Impact and Innovation" strategies. 2 of the 5 pre-approved strategies are:

  1. An embodied carbon reduction of at least 20% compared to a baseline building.

  2. Upfront carbon emissions equal to or less than zero.

In ZCB Performance v2, 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.
