Energy
Energy consumption is a direct cause of
CO2 emissions from a school.
Energy Types which leaves carbon footprint:
Electricity
LPG
Coal

Resources
Schools are large consumers of resources
from paper and books to food and sports
equipment.School is often unaware of the source of
many products used in the school

Waste
Waste produced represents the grave for
the life cycle of the majority of products
used within the schools.
Indirect CO2 emissions from waste
products are caused by transportation to
disposal facilities and the emissions from
the breakdown or combustion of thewaste.

Food
Chilled or frozen food require much more
energy for storage (and hence a higher
carbon footprint).
Frozen foods tend to be stored for longer,
thus accumulates a higher carbon footprint
by the time they are consumed.

Transportation
Transport in educational Institutes is used not justfor movement of students but also for movementof resources
Each liter of fuel burnt produces carbon in the formof carbon dioxide.
Amount of CO2 produced depends on the fuel
efficiency of vehicle and distance traveled.
E.g: 170 gms of CO2 for small cars per passengerper km, 310 for medium cars and 600 for buses.

Measurement of carbon footprint in Indian
educational institutes
Indian educational institutes have woken
up to the environmental issues.
There have been conscious efforts tomeasure and reduce the carbon footprints
Anna University, Chennai took an initiative
to measure the carbon footprint in its
campus.

Energy is the area where the university spends the most The major electricity usage is by air conditioners inside the
campus which is also the potential source of CFC emission
Use the air conditioners more effectively and only in areas ofnecessity

Noise Audit
Mainly due to the vehicular movement,anthropogenic sounds, laboratory works,operation of generators, machineries etc
Noise-meter readings were taken at variouslocations such asCanteen Blocks

4 All other utility areas 67.2 82.6
Environment Rules 1986, state that ambient noise levelsshould be within 55 db for residential areas.
Equipments causing higher noise levels should be properlyinsulated or replaced.
Noise barricades be provided in classrooms and librariesalong with noise absorbants

Water Audit
Water audit identifies productive use andneedless waste
A comprehensive water audit can uncovercostly inefficiencies in water utilization and
distributionData was collected for water audit through
following methods:University water supply data from estate office
Trends for water usage for gardening, laboratory,canteen etc through secondary data at estate office
Water lost is calculated as(operational time of the pumps, h/day) (pumps capacity, m3/h)

Education for Sustainability
Tomorrows future decision makers should
be trained today
Proactively teach students about theenvironmental and social impacts
Besides green awareness let students
learn through holistic training and practical
experience

Commitment to emissions reduction
High level of commitment from all the
stakeholders
Top leadership to guide the authoritythrough actions such as:
Integrated Planning

Institutional structures and support
Sustainability plan is a people centric
process
Requires coordinated efforts from eachindividual
Institutes should integrate the
sustainability plan across all verticals
Important people should be at the key
posts to ensure smooth implementation
and working of the plan

Emissions inventory
Calculation of Carbon footprint is most
important step
All calculated data should be properly
recorded and archived for comparisonlater
In case historic data is unavailable,
Institutes should start recording presentdata for future use
Both Indirect and direct emissions must be
calculated

Cost-Benefit & Feasibility Analysis
Analyze wide variety of options/plans forimplementation. For e.g.
Purchasing green utility power
Using CFLs
Buying retail carbon offsets
Rank options in terms of cost and the CO2reductions
Feasibility is generally done in these two areas:
Infrastructure
Behavior Changes

Planning for the Long Term
All sustainability plans should be long term
Besides proper planning and execution,
proper monitoring is also requiredYale university publishes annual reports
containing the progress of the
sustainability plans
All plans should can be incorporated right
at induction of students and can be made
a part of the curriculum too
