Carbon Footprint Measurement

Carbon footprints in educational institutesis contributed by:

Energy

Resources

Water

Waste

Food

Transportation


2/22

Energy

Energy consumption is a direct cause of

CO2 emissions from a school.

Energy Types which leaves carbon footprint:

Electricity

LPG

Coal


3/22

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

Estimate of 700 gms ofCO2 per kWh of energy produced

Water

Water pumping and treatment causes

CO2 emissions.

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.

6/22

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.


7/22

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.


9/22

Environment Performance of Educational

Institutes

Energy consumption pattern in the University

Water audit and to give sustainable solutions for

usage

Effect of noise inside the campus at various locations

Environmental performance analysis of theeducational institution

Prepare an Ecomap for the University campus


10/22

Energy Audit

Real time readings of electrical energy

consumption taken for each building

during the three periods:

Examination Period

Weekend

Semester Break

Utility areas was studied for the luminance

and the comfort of the user

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

13/22

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

Class rooms

Conference Hall

Hostel Blocks

Main Building


14/22

Noise Audit: Results

S. NO Location Noise Level

(db)

1 Classrooms, Main Building,

Other study areas

53.7 76.4

2 Near hostel buildings 54.567.2

3 Near running machineries,

laboratories

58.6 78.2

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


15/22

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)


16/22

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


17/22

The Sustainability Plan

Commitment to emissions reduction

Institutional structures and support

Emissions inventoryDeveloping the plan

Recommendations, approval and

implementationClimate action planning over the long haul


18/22

Commitment to emissions reduction

High level of commitment from all the

stakeholders

Top leadership to guide the authoritythrough actions such as:

Integrated Planning

Campus Initiatives

Governmental Laws

Some Campus Initiatives


19/22

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


20/22

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


21/22

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


22/22

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
