The 2018 report marks the first year of working toward adherence to the criteria of the Global Reporting Initiative (GRI), the world’s most widely used sustainability reporting framework. This year, we are reporting both waste and energy data in reference to applicable GRI standards. In prior reports, we have used different units and have included energy use from leased buildings and subcontractors, which is not aligned with GRI standards. For this reason, we are also including data in this 2018 report that is comparable to prior years, both in terms of units used and including leased buildings.
The following material references Disclosures 302-1 from GRI 302: Energy 2016 and 306-2 from GRI 306: Effluents and Waste 2016 for each standard used. Emission factors and conversion factors used are from the U.S. EPA and the U.S. Energy Information Administration (USEIA) websites. Waste disposal method is determined from information provided by the waste disposal partner.
Last year also marked the addition of an Environmental Analyst to our team. We have thoroughly reviewed all data, updated emission factors, and applied standards and recommendations from the GRI reporting framework and applied these improvements retroactively to 2010. These changes are reflected below.
