This year Interpublic has continued our journey of calculating GHG emissions by expanding our initial boundary to include offices in the United Kingdom. This is in addition to our original boundary which included our largest offices in North America. In North America we included all offices which are over 100,000 square feet and in the UK we included 90% of our leased facilities and 100% of our owned facilities. Our Scope 1 and Scope 2 calculations in North America 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 2014 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.
The expanded boundary as of the end of 2015 included 29% of our worldwide headcount, and 27% of our worldwide square footage.
Below are the combined calculated Scope 1 and 2 emissions come solely from electricity usage and heating fuel:
- 2014: 1,059.8 MTCO2e
- 2015: 1,301.3 MTCO2e
- 2014: 13,025.2 MTCO2e
- 2015: 14,101.0 MTCO2e
The 2014 and 2015 uncertainty number for Scope 1 is ~3% and the uncertainty for Scope 2 is ~12%.
Below is our Electricity and Fuel (Natural Gas) usage
- 2014: 34,179 MWh
- 2015: 36,763 MWh
Fuel (Natural Gas):
- 2014: 5,784 MWh
- 2015: 7,106 MWh
These numbers include electricity, and fuel (natural gas) as detailed above in our energy calculations, and use the number of full time employees as an intensity denominator.
- Energy Per Employee 2014: 2.90 MWh per Employee 2015: 3.12 MWh per Employee
- Energy Per Square Footage 2014: .014 MWh per Sq Ft 2015: .014 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 as an intensity denominator.
GHG Emissions Per Employee 2014:
1.02 MTCO2e per Employee 2015: 1.10 MTCO2e per Employee
GHG Emissions Per Square Footage 2015:
.005 MTCO2e per Sq Ft 2015: .005 MTCO2e per Sq Ft
