January 21, 2016 Loomis-‐Chaffee School: Carbon Footprint Review Prepared By: Michaelanne Butler, Charitable Carbon Offset Program Officer To our friends at Loomis Chaffee, Jadora's CCOP team at has thoroughly enjoyed working with Loomis-‐Chaffee School in these early stages of their carbon accounting journey. We are thrilled to at the possibilities this milestone opens up for future sustainability endeavors. This letter is to certify that Jadora International has carefully reviewed and re-‐reviewed this phase of Loomis' Carbon Footprint Report (CFP) methodology for accuracy and certainty. While further review may be necessary when a historic inventory is compiled, we are confident in the integrity of the present inventory. The report below details Loomis' overall carbon footprint (CFP) and a multi-‐level benchmark analysis for accuracy and integrity, which will inform both present offsets and future conservation efforts. Thank you,
Michaelanne Butler, CCOP Officer
Carbon Footprint Review: In checking for accuracy and integrity of an Institution's Carbon Footprint, Jadora International's standard review process involves as three layers of analysis: 1. Peer Benchmarking: Prior to delving into the inventory data, this process checks for red flags by comparing gross CFP to that of similarly situated institutions. For Loomis-‐Chaffee, the institutional criteria of comparison were a) student populations under 1,200, b) located in the rural Northeastern United States, and c) publically available carbon footprint data. According to this analysis, Loomis' reported emissions appear to be within an acceptable range for rural preparatory schools.

2. Normalized Emissions Comparison: Again, checking for red flags, this process compares actual CO2e emissions to normalized emissions per square foot projections based on data gathered by the American College and University Presidents' Climate Commitment (ACUPCC). Encouragingly, Loomis' actual emissions are lower than the national average (calculated at .013 MT of CO2e per 1,000 square feet of building space) predicted.

3. Data Review In the absence of red flags, the final step in the review process takes a detailed look at the original CFP calculations for consistency and accuracy. Without historic CFP data to work from, Jadora worked with Jeff Dyreson, the Director of Environmental Sustainability, and a dedicated taskforce to compile and calculate Loomis' first CFP in accordance with ACUPCC and the Association for the Advancement of Sustainability in Higher Education (AASHE) best practices. These best practices require reporting those emissions generated directly on campus (Scope 1), by purchased electricity, steam, or chilled water (Scope 2), and some of those generated by commuting, air travel, and solid waste (Scope 3).

Data Review Cont. While best practices do not require institutions to include student travel to and from home in their CFP calculation, Loomis has opted for a more rigorous CFP accounting standard by including this optional information. For the purposes of comparison, the above calculation excluded this data, but you will find a complete account of Loomis' carbon footprint below.
