The document discusses the history and concept of carbon footprints. It traces the origins of the term to the early 1990s and its popularization through a BP media campaign in 2005. It defines a carbon footprint as the total greenhouse gas emissions caused directly and indirectly by an individual or organization. The document provides examples of activities and their equivalent carbon dioxide emissions. It also discusses the effects of large carbon footprints such as climate change and resource depletion.

2. HISTORY OF CARBON
FOOTPRINT?
 A carbon footprint has historically been defined as the
total set of greenhouse gas (GHG) emissions caused
by an organization, event, product or person.
 It is probably an extension of the concept of
"ecological footprints" developed by the ecologist
William Rees at the University of British Columbia in
the early 1990s. Dr. Mathis Wackernagel, executive
director of the Global Footprint Network, states that
the phrase "carbon footprint" received "its biggest
boost in 2005 through an enormous BP media
campaign on the carbon footprint.

3. WHAT IS CARBON FOOTPRINT?
 The total amount of greenhouse gases produced
to directly and indirectly support human
activities, usually expressed in equivalent tons of
carbon dioxide (CO2).
 Your carbon footprint is the sum of all emissions
of CO2 (carbon dioxide), which were induced by
your activities in a given time frame. Usually a
carbon footprint is calculated for the time period
of a year.

4. BASIC CALCULATION
Fuel Unit CO2 emitted per unit
Petrol 1 liter 2.3 kg
Gasoline 1 liter 2.3 kg
Diesel 1 liter 2.7 kg
Oil (heating) 1 liter 3.0 kg
If your car consumes 7.5 liter diesel per 100 km, then a
drive of 300 km distance consumes 3 x 7.5 = 22.5 liter
diesel, which adds 22.5 x 2.7 kg = 60.75 kg CO2 to your
personal carbon footprint.

5.  Each of the following activities add 1 kg of CO2 to your
personal carbon footprint:
 Travel by public transportation (train or bus) a distance of 10 to
12 km (6.5 to 7 miles)
 Drive with your car a distance of 6 km or 3.75 miles (assuming
7.3 litres petrol per 100 km or 39 mpg)
 Fly with a plane a distance of 2.2 km or 1.375 miles.
 Operate your computer for 32 hours (60 Watt consumption
assumed)
 Production of 5 plastic bags
 Production of 2 plastic bottles
 Production of 1/3 of an American cheeseburger

6. WHAT IS GHG?
 Greenhouse gases are those that can absorb and emit
infrared radiation . In order, the most abundant
greenhouse gases in Earth's atmosphere are:

7.  Carbon dioxide is a so called greenhouse gas causing
global warming . Other greenhouse gases which might
be emitted as a result of your activities are e.g. methane
and ozone. These greenhouse gases are normally also
taken into account for the carbon footprint. They are
converted into the amount of CO2 that would cause the
same effects on global warming (this is called equivalent
CO2 amount).
 The carbon footprint is a very powerful tool to understand
the impact of personal behaviour on global warming.

9. MAIN EFFECTS
Climate Change
 Climate change is the ultimate effect of large carbon footprints.
Greenhouse gases, whether natural or human-produced, contribute to
the warming of the planet. From 1990 to 2005, carbon dioxide
emissions increased by 31 percent. By 2008, the emissions had
contributed to a 35 percent increase in radiative warming, or a shift in
Earth's energy balance toward warming, over 1990 levels.
Depletion of Resources
 Large carbon footprints deplete resources on large and small scales,
from a country's deforestation activities to one home's increased use of
air conditioning. The more those with large carbon footprints use
resources, the more greenhouse gases increase and spur further climate
change

10. CASE STUDIES

11. INTERNATIONAL
 L’Oréal sites around the world are contributing to the group's
ambitious greenhouse gas reduction target:
 North Little Rock, Arkansas factory completed a hydropower
agreement in 2009 to halve its GHG emissions.
 Warehouse in Mexico City has one of the largest solar installations in
Latin America, and expects to reduce equivalent CO2 emissions by
54 tonnes a year.
 Yichang factory in China has installed 2,000 solar tubes for the
preheating of water, which will reduce CO2 emissions by more than
5.3 tonnes a year.
 Factory in Burgos (Spain) has made a public commitment to be
carbon neutral by 2015 by using green technologies including solar
arrays, bio-fuel and geothermal energy.
INDIA
 L'Oreal's plant in Pune uses solar heating to preheat wash water,
saving 93 tonnes of CO2 per year, or 6% of total energy use. There
are 320 solar panels spread over 920m2.
