DEFINITION OF 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.
The carbon footprint is a measurement of all
greenhouse gases we individually produce and
has units of tonnes (or kg) of carbon dioxide
equivalent.

Sea level rise
Impacts on agriculture
Reduction of the ozone layer
Increased extreme weather
Spread of diseases
Ecosystem change
What will happen in the future if
we do nothing?
• Climate model simulations predict an increase in average
surface air temperature of about 2.5°C by the year
2100 (Kattenberg et al., 1996).
• The likelihood of "killer" heat waves during the warm
season will increase (Karl et al., 1997)
• The IPCC Second Assessment Report estimates that
sea-levels will rise by approximately 49 cm over the next
100 years, with a range of uncertainty of 20-86 cm.
• Sea-level rise will lead to increased coastal flooding
through direct inundation and an increase in the base
for storm surges, allowing flooding of larger areas and
higher elevations.
• Further melting of the Arctic Ice Caps (at the current
rate) could be sufficient to turn off the ocean currents
that drive the Gulf Stream, which keeps Britain up to
6°C warmer than it would otherwise be.
Reduction of carbon footprint
For individuals
• Turn off your lights, TV, DVD player,
mobile phone, computer, when you don’t
use them.
• Turn down the central heating slightly
• Fill your dishwasher and washing machine
with a full load.
• Do your daily shopping, when you go
home after work
• Slow down your driving
• Use laptop
• Switch down your screensaver setting to
blank screen
• Use biogradable nappies.
• Fit energy saving light bulbs
• Recycle your grey water
• Replace your old fridge or freezer if it is older
than 15 years old
• Replace your old boiler with a new energy
efficient condensing boiler
Traveling
• Use bicycle, bus or train rather than your
car
• For short journeys either walk or cycle
• Try to reduce the number of flights you
take
Buying habits
• Don’t buy bottled water if your tap water is
safe to drink
• Buy local fruit and vegetables, or even try
growing your own
• Growing your own camomile or mint for
herbal tea rather than using factory made
tea bags
• Buy in season. Locally produced goods
• Reduce your consuption of meat
• Don’t buy fresh fruit and vegetables which
are out of season, they may have been flown
in
• Try to only buy products made close to home
• Buy organic produce
• Don’t buy packaged products
• Recycle as much as possible

Total = 15.18 tonna CO2
• My average footprint in a year is 15.18 ton
CO2
• The average footprint of population of
Hungary is 5.65 ton CO2
• The average footprint of industrial
coutries is 11 ton CO2
• The average footprint of the world is
about 4 ton CO2
• If we want to stop the climate change we
should have just 2 ton average footprint
