2. INTRODUCTION
 The impression left by a foot or shoe on the ground is
known as footprint.
 In ecology footprint means the unit of biologically
productive area a living organism need for its survival.

3. What is Ecological footprint
 Mathis Wackernagel and William Rees in 1990s
created the concept of ecological footprint and called
it as appropriated carrying capacity.
 WWF described it as impact of human activities
measured in terms of the area of biologically
productive land and water required to produce the
goods consumed and to assimilate the waste
generated.

5. ADVANTAGES OF ECOLOGICAL
FOOTPRINT
 Ecological footprint is a single unit that allows
disaggregation of indicators.
 It can be widely applied to various programs/ activities.
 Ecological footprint can be specific or general.
 It is a very useful as a means of communication policy.
 The method is constantly being updated and improved by
Global Footprint Network.
 It is able to indicate the nature of limited natural capital.
 It has an ability to analyze sustainable development
concept into measurable objective.
 Unit of ecological footprint is global hectare (gha).

6. DISADVANTAGE OF ECOLOGICAL
FOOTPRINT
 Ecological footprint analysis uses hypothetical land ,
which does not represent actual land use.
 It simplifies the use of natural resources.
 Most are portrait of consumption.
 It does not provide clear policy guidance except for the
subtraction of consumption.
 It is based on questionable assumption.

7. CARBON FOOTPRINT
 Global warming , polar ice melting is one of the most
harmful problem caused by greenhouse gases.
 The concept of carbon footprint was first introduced
by British petroleum
 Carbon footprint is based on ecological footprint.
 WHO stated that, carbon footprint is a measurement
of the impact of human activities have on the amount
of carbon dioxide produced through the burning of
fossil fuel.

8. IMPORTANCE OF CARBON
FOOTPRINT
 Measure the amount of carbon based waste(mainly
Carbon dioxide) produced by an individual.
 Measurement of pollutants helps in developing
sustainable development programs.
 Helps in identification of large carbon releasing
industries.
 Helps in analysis of production of greenhouse gases
and its effect in future time.
 It helps in the identification of large carbon producing
area. E.g.- China, producing 10.06 billion metric tones.

9. FUTURE ASPECT OF ECOLOGICAL
AND CARBON FOOTPRINT
 Country like Qatar has high ecological footprint ( more
than 14 gha) and Malawi has only 0.76gha.
 By the analysis of ecological footprint we can manage the
unbalance in resource utilization with more sustainable
method.
 Analysis of carbon footprint will provide us a more accurate
data about greenhouse gas production and its sources.
 After analyzing the carbon footprint of fossil fuel we must
have to focus our direction towards sustainable energy
source.

10. ECOLOGICAL FOOTPRINT
 In future both ecological and carbon footprint will be
very helpful for the management of waste, control of
pollution and development of sustainable method to
protect the earth environment.
 According to Global Footprint network we need 1.69
earth to fulfill our requirements in 2016. we crossed
the earth limit in 1970.

11. CONCLUSION
 “we do not inherit the earth from our ancestors, we
borrow it from our children.”
- R.W. Emerson
