Note this response is cross-referenced for 302-1, 302-3, 302-4, 305-1, 305-2, 305-4, and 305-5.
302-1 – Energy consumption within the organization
302-3 – Reduction of energy consumption
302-4 – Direct greenhouse gas (GHG) emissions (Scope 1)
305-1 – Energy indirect greenhouse gas (GHG) emissions (Scope 2)
305-2 – Reduction of greenhouse gas (GHG) emissions
305-4 – Energy intensity
305-5 – Greenhouse gas (GHG) emissions intensity
This year Interpublic continued our journey of calculating GHG emissions by expanding our boundary to include all offices which are over 50,000 square feet worldwide. The boundary was expanded from last year’s which included all of North America over 50,000 square feet and select buildings in the UK and France. The expanded boundary as of the end of 2017 now includes 48% of our worldwide headcount (up from 37%) and 53% of our worldwide square footage (up from 45%).
Our Scope 1 and Scope 2 calculations in all countries besides the UK were completed using Measurabl, the online sustainability data software, which aligns its carbon accounting algorithms to the WRI/WBCSD’s GHG Protocol, Revised Edition methodologies. To calculate carbon emissions, we use US EPA e-Grid emissions factors for buildings within the United States and national-level emissions factors for buildings outside the United States.
To calculate our UK emissions, we were supplied with an annual emissions report by Green Element. The calculations completed by Green Element are in accordance with the GHG Protocol using 2017 conversions factors for purchased electricity and gas. Where up to 3 months’ worth of data was not available or accurate, the missing data was estimated using a monthly average for that supply.
Below are the combined calculated Scope 1 and 2 emissions:
- 2016: 2,485.6 MTCO2e
- 2017: 2,358.1 MTCO2e
- 2016: 26,975.1 MTCO2e
- 2017: 25,877.4 MTCO2e
Below are our Electricity and Fuel usage (Natural Gas and Heating Oil)
- 2016: 75,102.2 MWh
- 2017: 74,030.2 MWh
Fuel (Natural Gas & Heating Oil)
- 2016: 13,991.6 MWh
- 2017: 12,916.9 MWh
These numbers include electricity, fuel (natural gas & heating oil), and central steam/heating where it was available, and use the number of full-time employees or square footage within our boundary as an intensity denominator.
Energy Per Employee:
- 2016: 3.84 MWh per Employee
- 2017: 3.77 MWh per Employee
Energy Per Square Foot:
- 2016: .0169 MWh per Sq Ft
- 2017: .0166 MWh per Sq Ft
GHG Emissions Intensity
These numbers include Scope 1 and Scope 2 emissions as detailed above in GHG Emissions numbers and use the number of full-time employees or square footage within our boundary as an intensity denominator.
GHG Emissions Per Employee
- 2016: 1.22 MTCO2e per Employee
- 2017: 1.17 MTCO2e per Employee
GHG Emissions Per Square Footage
- 2016: .0054 MTCO2e per Sq Ft
- 2017: .0051 MTCO2e per Sq Ft
