Carbon Footprint 2011-2012
During the 2012-2013 school year, a carbon inventory
was completed for the 2011-2012 fiscal year. In the program this is designated
as 2011-2012 Report.
The program breaks down emissions into three
categories: Scope 1, Scope 2, and Scope 3.
Scope 1 emissions are direct emissions that come from
sources that are owned and/or controlled by Lebanon Valley College. LVC has
complete control over these emissions such as the fossil fuel combustion of
campus fleet vehicles. These are the direct responsibility of the college.
Scope 1 emissions for LVC result from fossil fuel and fertilizer usage. The
campus uses natural gas and distillate oil for heating buildings; most
buildings use natural gas. Diesel fuel and unleaded gasoline used for running
the college fleet also fall into the scope 1 category. Refrigerants and other
chemicals would be another source of scope 1 emissions, but the college ensures
that these chemicals are properly cared for and not released as emissions.
Scope 2 emissions are indirect emissions from sources
that are not owned or operated by Lebanon Valley College. However, these
sources are directly linked to the energy used by the campus. While the college
is not of direct responsibility of these emissions, it is the fault of the
college for the need of these emissions due to demand. For Lebanon Valley
College, purchased electricity is the only source of scope 2 emissions. The
monthly records for electricity purchases is available from the office of
Facility Services and is also among the publicly available spreadsheets
provided in the department’s public drive.
other emissions are attributed to the Scope
3 category. These emissions are typically considered as “optional” and are
harder to classify. Either these emissions are the result of direct financing
or encouragement of the college, but are not from sources owned or operated by
LVC. Some great examples of this would be study abroad travel and faculty,
staff and student commuting. The responsibility of these emissions is unclear
but must be carefully monitored in order to ensure the emissions are not
gathering all the necessary data, the Campus Carbon Calculator was used to
analyze the emissions produced by Lebanon Valley College.
Inventory Results Summary
Before any mitigation strategies, total
emissions from all three scopes were 10362.7 MTeCO2,
or metric tons of Carbon Dioxide Equivalents. Figure 1, below, shows the
breakdown of total emissions by scope and Figure 2 provides a more detailed
breakdown of emissions by sources. The Scope 2 emissions category accounts for
nearly half of total emissions. The final figures display the total amount of MTeCO2 reduced since 2008 as well as some
percentage changes from 2008 to 2012.

Emissions by Source
most significant Scope 1 emissions, producing 2012.1 MTeCO2,
are from Other On-Campus Stationary, which includes distillate oil and natural
gas mainly used for heating campus buildings. Approximately 95% of Scope 1
emissions is attributed to Other On-Campus Stationary and also makes up 19.4%
of total emissions. Overall Scope 1 emissions made up 20.3% of overall
emissions and are equivalent to 2104.5 MTeCO2.
Scope 2 emissions consist solely of purchased
electricity, which makes up 47.4% of total emissions and is equivalent to 4909.8
MTeCO2. The majority of our
mitigation strategies aim to decrease our electricity emissions since it is
such a significant part of LVC’s carbon footprint.
3 emissions contribute 32.3% of total emissions or 3348.4 MTeCO2. The main contributor to Scope 3
emissions is student and faculty commuting. Student commuting makes up 39.7% of
Scope 3 emissions, with 1330.8 MTeCO2,
and 12.8% of total emissions.

Figure 4 focuses primarily on the progress of Lebanon Valley College
from the beginning of fiscal year 2008-2009 to the end of fiscal year 2011-2012.
Many of the sources have decreased around six and seven percent. The college
has decreased emissions from each source except faculty/staff commuting and
paper. The graph below graphically explains this trend with the sudden spike
that occurred between fiscal year 2008-2009 and fiscal year 2009-2010. Then
there was only a slight increase and now the emissions have leveled out and
have even decreased slightly. The 8 percent increase in paper has been
addressed this year by implementing an allowance system among the students.
Each student is allowed a certain number of pages and once that limit is
approached the student will need to pay for additional pages. The college hopes
this allowance system offers incentives for students to think twice before
printing and lower overall paper usage.
