GHG emissions

GHG emissions

The actual greenhouse gas (GHG) emissions have decreased by 7.1% since 2011, and in 2015 were 314,503 tCO2e^This decrease is a result of several initiatives Bentall Kennedy has rolled out in recent years, including the LEED Volume, Target Setting and BOMA Portfolio programs. The emissions breakdown for 2015 are as follows:

Direct Scope 1 GHG Emissions         76,901 tCO2e^  
Indirect Scope 2 GHG Emissions (location-based)      237,602 tCO2e^
Total Actual GHG emissions      314,503 tCO2e^

Our indirect Scope 3 emissions across North America in 2015 totaled 18,855 tCO2e. Scope 3 emissions are related to the consumption of water and generation of waste, as well as emissions outside of Bentall Kennedy's operational control (e.g. tenant sub-metered electricity). 

One way we are managing GHG emissions is through the purchase of renewable energy credits (RECs) and Carbon Offsets. We continue to purchase RECs and Offsets to help reduce the increase in our emissions and support more sustainable sources of energy. Bentall Kennedy is 
proud to support the development of renewable power in both Canada and the United States. At the same time, we are aware that greater efforts to conserve energy and reduce GHG emissions are required. The combined benefits of reducing GHG emissions, environmental and social impacts from new generation required, and the cost savings associated with it make energy efficiency and conservation a triple bottom line winner. 

As a manager, we monitor performance on a like-for-like basis using normalized data. The Normalized Market-based GHG Emissions graph below shows the effect of the RECs and Offsets purchased as well as the normalization of our data - demonstrating a decrease in normalized GHG emissions of 8.8% since 2011.

GHG emissions intensity

Emissions intensity by asset type is calculated based on the total annual normalized GHG emissions and the total square footage, based on gross leasable area (GLA). The graphs below show the intensity by asset type in Canada and in the U.S. 

The most notable intensity improvements have occurred in the office assets in Canada where GHG intensities dropped by 21.2% since 2011. This large decrease in office intensity is mainly due to improved energy performance and an increase in the purchasing of RECs at properties across Canada. In the U.S., multi-family and medical office properties decreased their GHG intensity by 6.7% and 1.8% respectively.  While the GHG intensity of U.S. offices increased, this has slowed to only 1.5% since 2011 (last years' five-year increase was 4.7% for offices). This improvement highlights the success from performing a systematic practice of conducting energy audits and preparing all offices for a 2016 launch of the Target Setting Program.

about the data

To understand the data shown here, it's useful to understand several of the terms being used: net versus gross, location-based versus market-based, normalization, and changes in the portfolio. The changes in portfolio size are shown in the table below. 

Actual GHG Emissions Data: The current year actual GHG emissions data is calculated in accordance with the Greenhouse Gas Protocol using the Operational Control approach and the location-based method that reflects the average emissions intensity of grids on which energy consumption occurs. The data does not account for renewable energy credits, Offsets or the impacts of normalization. The prior year data has been adjusted to reflect any acquisitions, dispositions, completed new developments and changes in emission factors in 2015.

Normalized GHG Emissions Data: The current year normalized GHG Emissions data is calculated using the market-based method that reflects the purchase of renewable energy credits. The normalized GHG emissions data also accounts for Offsets and includes any newly developed buildings but does not include buildings that have been acquired or disposed of in the past 5 years. Data for historical years is adjusted to reflect 2015 weather, occupancy, exceptional tenant loads and emission factors.

Also of note, while we have data for several years prior to 2011, and strong GHG reductions for those years, we have aligned with best practice and use a 5 year rolling baseline. We do this in order to focus attention on continuous improvements in the existing portfolio.

GHG emissions estimates: Data reflects the office, retail, medical, multi-family and light industrial assets for which we have high-quality information. 98% of the energy data tracked in Eco Tracker or Eco View is based on actual utility consumption as recorded through utility bills. The balance is estimated using modeling and historical analysis.  In addition, data includes estimates to ensure completeness over the GHG emissions for properties that are under Bentall Kennedy’s operational control but were not included in our data sets as of December 31, 2015.
