Greenhouse Gas Emissions Inventory FY 11

Transcription

1 Summary Greenhouse Gas Emissions Inventory FY 11 The Fiscal Year 2011 Greenhouse Gas Inventory details greenhouse gasses (GHG) emitted by Hobart and William Smith Colleges (HWS) during the 2011 fiscal year, June 2010 to May Data were collected in spring 2012 and inputted by Project Specialist Joel Andruski H 11 and Student Intern Noah Lucas H 13 under the supervision of Sustainability Manager James Landi H 08 and Professor Tom Drennen to Clean Air Cool Planet s (CACP) GHG Calculator. The FY 11 GHG Inventory accounts for all direct and indirect sources of greenhouse gasses specified by CACP s accounting scope and methodology. In FY 11, Hobart and William Smith Colleges net emissions were 14,357 metric tons of carbon dioxide equivalent (MTCDE). This compares to the Colleges FY 09 net emissions level of 14,910 MTCDE. The format and methodology used in FY 11 Inventory were similar to those used in FY 09 with the exception of minor modifications to the analysis of Scope 3. Scope 1 & 2 Emissions represent the most consistent year to year performance comparison. In FY 11 emission levels from Scope 1 were 6091 MTCDE and FY 09 were 6,208 MTCDE, respectively. Scope 2 emission levels were 3,443 MTCDE in FY 11 and 3,878.2 MTCDE in FY 09. Percent reduction between FY 11 and FY 09 Scope 1 and 2 emissions were 6%. The results from this inventory will help HWS track emission reduction progress and identify emission reduction priorities in its goal to achieve climate neutrality (net- zero greenhouse gas emissions) by Methods The Clean Air Cool Planet Greenhouse Gas Calculator groups GHG emissions into three scopes : Scope 1: Heat Generation Campus Vehicle Fleet Fertilizer Applications Refrigerant Chemical Leakages Electricity used by Electrically Powered Vehicles Scope 2: Purchased Electricity Scope 3: Faculty, Staff and Student Commuting Directly Financed Air Travel Directly Financed Vehicle Miles Air Travel to Study Abroad Programs Solid Waste Disposal The FY 11 GHG Inventory s Scope 1 & 2 accounting methodologies are the same as FY 09. Scope 3 accounting methodologies do, however differ significantly from FY 07 to FY 09 and also FY 11 Inventories. Details about Scope 3 accounting methodologies for the FY 11 Scope 3 Emissions are in File: Carbon Calculator_Reference_ , Sheet: Variations in Accounting. 1

2 Data Collection All data collection for FY 11 GHG Inventory was gathered upon request by James Landi, Sustainability Coordinator. Data collected for natural gas use, electricity consumption, the university fleet s fuel consumption, total solid waste production, refrigerant chemical leakage, fertilizer applications, and renewable energy credits was received from HWS Buildings and Grounds. Tom D Agostino from the Center for Global Education provided study abroad travel itineraries. Transportation data for faculty, staff, and student commuting was compiled from survey responses: o 272 students responded to the Student Transportation Survey; a 13% response rate, and 290 faculty and staff responded to the Faculty and Staff Transportation Survey; a 41% response rate. The FY survey was modified from a previous FY version. The surveys are provided in Figure 10A and Figure 11A. The survey was distributed electronically using HWS s IT based program, Surveyor and submissions were anonymous. The surveys can be found in the Surveyor Program under subject heading environmental studies o FacStaff Survey Title: HWS Faculty and Staff Transportation Questionnaire o Student Survey Title: HWS Student Transportation Questionnaire Athletic team travel was gathered from the Hobart and William Smith athletics. Coaches indicated the teams mode of transportation next to travel schedules. In addition, coaches were asked to report any team travel that was not formally listed on the schedule, e.g. spring break team trips. Once the coaches had responded the distances travelled in road vehicles (buses, cars or rental vans excluding campus vans) were calculated using Google Maps. o Hobart and William Smith Colleges were assigned as the start point with the final destination being the campus of the scheduled opponent (unless otherwise indicated by the coach). Distances travelled by air were calculated using the itineraries provided by Center for Global Education, coaches, and faculty responses from the transportation survey that they completed. The distances were calculated using The website calculated the distance travelled by airplanes on each leg of the trip. Details by Scope Scope 1 Figure 1 On- Campus Stationary 109,660.1 MMBTU of Natural Gas MTCDE Resulting Greenhouse Gas Emissions HWS only uses natural gas or purchased electricity (accounted for in Scope 2) to heat properties Data provided was in therms. The CA- CP calculator required on- campus stationary to be reported in MMBTU conversion was made by multiplying Therms X.1 MMBTU/Therm.

Electricity consumption from the electric vehicles is not currently distinguishable (not submetered) from the campus total electricity consumption and is included in Scope 2 purchased electricity.

The nitrogen content recorded in the CA- CP calculator was 17.5% nitrogen in the synthetic fertilizer applied.
