Yes or No
Business travel Yes
Commuting Yes
Purchased goods and services No
Capital goods No
Fuel- and energy-related activities not included in Scope 1 or Scope 2 No
Waste generated in operations No

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

In 2001, the State of California created the nonprofit California Climate Action Registry (CCAR) to facilitate the voluntary accounting and reporting of greenhouse gas emissions within the state. CCAR stopped collecting emissions inventories in 2010 and transitioned its membership to the Climate Registry (TCR), a nonprofit emissions registry for North America.

The CCAR General Reporting Protocol required filing of Scope I & II emissions with independent third party verification, and encouraged participants to file inventories of Scope III emissions as well. Stanford joined the CCAR in 2006 and used this protocol to prepare and file its GHG emission inventories through 2009. In 2010, Stanford transitioned to TCR protocol for its third-party verified emissions inventory, and it has used the TCR in each subsequent year to date.

Scope III emissions at this time (business air travel and driving commuters) are compiled internally by Stanford's Parking & Transportation Services and are not formally verified.


Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
Yes

A brief description of the internal and/or external verification process:

Per the GHG inventory protocols that Stanford follows, independent third party verification of Scope I and II emissions is required.

Please see the following website for more details on the required verification protocol: http://www.theclimateregistry.org/resources/verification/general-verification-protocol/

A brief description of when and why the GHG emissions baseline was adopted:

Although Stanford University first reported its GHG emissions in 2006, the 2007 results provide a more accurate baseline for the university. Reporting in 2006 included a number of non-typical operations, including major maintenance operations at the Central Energy Facility. Therefore, 2006 results are not considered representative of the campus emissions.

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:

The $480 million Stanford Energy System Innovations (SESI) program is designed to meet the university’s energy demand while reducing greenhouse gas emissions and water consumption. SESI represents a significant transformation of the university from 100% fossil-fuel-based cogeneration to a more efficient electric heat recovery system and will result in immense benefits for Stanford University in the years to come.
The program converted Stanford’s heating supply from steam to hot water, requiring the installation of over twenty miles of hot water piping and changes to the mechanical rooms of 155 buildings. The project also included construction of a new Central Energy Facility (CEF), which came online in April 2015. The CEF includes heat recovery chillers, three large water tanks for thermal energy storage, and a high-voltage substation that receives electricity from the grid. Do to the heat-recovery chillers, the new CEF is 70% more efficient than the old cogeneration plant.

By the end of 2016, Stanford will procure 65% of its electricity from renewable sources, 78.5 MW of which will be owned by Stanford. This transition to renewable sources, along with the efficiencies gained from the new CEF and the conversion from steam to hot water, will reduce Stanford’s greenhouse gas emissions by 68%.

+ Date Revised: Dec. 2, 2015

The Stanford Energy System Innovations (SESI) project came online in April 2015 and will reduce campus greenhouse gas emissions by 68% by the end of 2016 through utilization of electric heat recovery technology at Stanford’s new Central Energy Facility combined with an agreement to build 78.5 MW of solar PV, 5.5 MW of which will be installed on campus. Details in the descriptive fields of this credit capture improvements that have been made as a result of SESI, but the data used in this credit represent performance years from before SESI came online and thus the scoring of this credit does not capture the benefits that have and will continue to come from this new energy system.

Please note that the GSF reported for the GHG inventory varies from the campus GSF reported for all other credits. The boundary of the GHG inventory is slightly different from the overall STARS boundary, and the GSF for the GHG inventory boundary is used for this credit. The difference primarily derives from the inclusion of off-campus leased spaces in the GHG inventory boundary. Additionally, Stanford has conducted an inventory of the GHG emissions associated with Purchasing, but the results were not included in Stanford's official GHG Inventory submitted through the Climate Registry.
