CARBON FOOTPRINT


2/16

What is carbon footprint?

A carbon footprint is a measure of the impact our activities

have on the environment, and in particular climate change.

It relates to the amount of greenhouse gases produced in our

day-to-day lives through burning fossil fuels for electricity,heating and transportation etc.

Myown carbon footprint.

y My personal Carbon Footprint is 4.32 tonnes of CO2

equivalent per annum* The global sustainable limit is 2

tonnes per annum.

y

In other words, the Earth would require 9.28 more treesevery year to balance the additional burden of my lifestyle

choices**

A carbon footprint is made up of the sum of two parts,

the primary footprint (shown by the green slices of the

pie chart) and the secondary footprint (shown as the

yellow slices).

1. The primary footprint is a measure of our direct

emissions of CO2 from the burning of fossil fuels

including domestic energy consumption and

transportation (e.g. car and plane). We have direct

control of these.

2. The secondary footprint is a measure of the

indirect CO2 emissions from the whole lifecycle of

products we use - those associated with their

manufacture and eventual breakdown. To put it very

simply the more we buy the more emissions will becaused on our behalf.

Why shouldyou knowyour carbon

footprint?

y Carbon footprint refers to the amount of greenhouse

gas(GHG) emissions.

y GHG affect earths ability to retain heat and results in global

warming which results in climate change.y Thus knowing ones greenhouse emission via carbon

footprint, will be the first step towards emission reductions

and climate-change impact


6/16

Why is it called carbon footprint?Since among the 6 identified gases, themost important and common of all is C02 although it has

GWP(Global warming potential) of 1, it is released from all day-

to-day activities. So it is called so

Howto calculate it?

3 simple steps-

1)Go visit this link http://www.no2co2.in/CarbonCalculator.php

(This specifically measures according to Indian standards)

2)Answer a few simple questions about your day today activities.3)Your CF score will be sent to you by mail.

Now all that is left is to work on ways

to reduce it.


8/16

How is it calculatedy The procedure used to calculate your Carbon Footprint complies with

the Guidelines (2006) of the Intergovernmental Panel on ClimateChanges (IPCC), for National Greenhouse Gas (GHG) EmissionsInventories. As far as possible, India-specific GHG emissionscoefficients are used in the calculations.

y Each activity and lifestyle choice impacts Carbon Footprint in manyways simultaneously. These impacts can be classified in a 3-tier

hierarchy comprising of1)primary -resulting from direct activity or consumption.

2)secondary-arising from the production of a product/service at anotherlocation.

3)tertiary- arising from the production of input materials and services in

the production of a product/service.y Each of these aspects has a progressively diminishing impact on

personal Carbon Footprint.

How is it calculated?Emissions are calculated for standard quantities and then are compared with data

entered to arrrive at the answer.

Emissions from, for

example,cars, aeroplanes and electricity generation are

well understood and documented.

Standardemissionsfactors have been calculated for these activities so that

actual emissions do not always have to be measured, but

can be calculated from other data such as amount of

fuel used.

Emissions factors have also been derived foractivities where it is not so easy to measure emissions

such as from agricultural and land use activities, although

these factors are much more uncertain.


11/16

Carbon Neutral

y The term carbon neutral refers to something

with a carbon footprint of zero.

Carbon

neutrality is normally achieved by first calculating acarbon footprint, then reducing emissions as far as possible, and

finally offsetting the remainder by purchasing emissions

reductions credits generated by external projects such as

renewable energy schemes or forestry projects.

ActionplanEnergy

Avoid using microwave to reheat extensively.

Reduce use of devices like straightner,hair dryer,electric brush which could be done without.

Make a conscious effort to switch off mobile and laptop chargers when not in use and advisefriends to do so too.

Travel

Try walking and avoid means of tranport.

Travel long distance by bus rather than car to reduce individual emission

Advice friends with two wheelers to switch off at signals

Diet Buy natural if not organic food

Consume meat only once per week, avoid milk sweets since milk cannotbe avoided.

Carry water rather than buy packaged ones

y The action plans can be implemented immediately and do

not need a time frame.

Woodand Carbon FootprintMaterials like plastic, metal and concrete all requires lot of energy for extraction of raw

materials and manufacture.These materials all have positive carbon footprints.

Wood has a negative footprint because of the carbon dioxide fixed by the original living

tree. The emissions associated with harvesting, transporting and processing of wood

products are small compared to the total amount of carbon stored in the wood.

This means that even when energy use for harvesting,

transport and processing are taken into account, wood still has a negative footprint.

So use wood based materials as much as possible

Carbon footprintand corporatesCarbon Footprint & Strategyy As regulatory frameworks on businesses around permissible carbon

emission limits and carbon trading are getting strengthened around theglobe, businesses are taking proactive initiatives to record their carbonemissions and devise ways to reduce the same.

y While greenhouse gas inventory reporting is currently not mandatoryin India, progressive companies are already identifying risks associatedwith GHG constraints and are voluntarily taking stock of their GHGemissions.

y A carbon strategy would chalk out steps for the company to ensure itsgrowth in the carbon constrained economy and maximize its carbonassets. The carbon strategy would also help companies to identifyclimate risks and opportunities, thereby reducing costs and enhancingrevenues as well as their corporate image.
