A Carbon Footprint measures the total greenhouse gas emissions caused directly and

indirectly by a person, organization, event or product.

• So every individual has a different value of carbon footprint.

• Carbon Footprint quantification analysis and reduction are key to preventing this

change by, for example, enhancing energy efficiency, mitigating carbon emissions by

means of green energy and then compensating for remaining GHG emissions by

investing in carbon offsets, with a final goal of being carbon neutral.

• To estimate the carbon di-oxide emission in the atmosphere.

• Carbon footprint is a focal indicator of environmental responsibility. It helps to

identify climate impacts and lower them cost-effectively and sensibly.

• The calculation results can be used in strategic and operative planning, constructing

a climate policy, environmental reporting and planning of cost savings. Carbon

footprint promotes positive, environmentally conscious company image and can

boost the marketing of an organization and its products.

• Calculating carbon footprint is an effective way of managing energy and

environmental issues.

• For this purpose it likely to be adequate to understand and quantify the key emission

sources through a basic process, typically including fuel, electricity and transport.

Different methods have been developed to calculator carbon footprint and many types

of online calculator are also available for the same. But Greenhouse Gas Protocol

produced by the World Resources Institute and the World Business Council for

sustainable development is one of the best method to calculate carbon footprint.

Scope of footprint-

• Emission through fuel and natural gas.

• Direct emissions : from onsite combustion and mobile sources.

• Indirect emissions: from purchased electricity and steam.

• Optional emissions: Examples include product transport, employee business travel

and employee commuting.

20% energy being lost in transmission

60% carbon is present in coal
