What is Carbon Footprint?
• A carbon footprint is defined as the
total amount of greenhouse
gases(GHG) including carbon dioxide
and methane produced to directly and
indirectly support human activities,
usually expressed in equivalent tons of
carbon dioxide (CO2).
• The carbon footprint is a very powerful
tool to understand the impact of
personal behaviour on global warming.

What is a carbon footprint?
• The sum total of all the greenhouse gas emissions that had to take
place in order for a product to be produced or for an activity to take
place.
• Unsurprisingly, in general terms the size of a person’s carbon
footprint tends to increase with wealth.
• Origin of carbon footprint can be traced back to as a subset of
“ecological footprint” proposed by Wackernagel and Rees (1996).

The United States Environmental Protection Agency (EPA) provides
information on emissions of the main greenhouse gases. It shows that
about 81% of the totally emitted greenhouse gases were carbon dioxide
(CO2), 10% methane, and 7% nitrous oxide in 2018. Therefore, carbon
dioxide (CO2) emissions (or carbon emissions) are the most important
cause of global warming.

HOW TO CALCULATE CARBON FOOTPRINT
7
• It isn’t easy to calculate a carbon footprint; indeed, it the
“essential but impossible” measurement.
• There are simply some calculators available on the internet.
• Never possible to be completely accurate but there should be a
board idea.

PARIS AGREEMENT
15
The UN Climate Change Conference (COP21) in Paris reached a breakthrough on 12
December 2015: the historic Paris Agreement.
Paris Agreement: Climate Change Deal

16.
PARIS AGREEMENT
The Agreement sets long-term goals to guide all nations:
• Substantially reduce global greenhouse gas emissions to limit the global
temperature increase in this century to 2 degrees Celsius while pursuing
efforts to limit the increase even further to 1.5 degrees;
• Review countries’ commitments every five years;
• Provide financing to developing countries to mitigate climate change,
strengthen resilience and enhance abilities to adapt to climate impacts.
• It entered into force on 4 November 2016. Today, 194 Parties (193
States plus the European Union) have joined the Paris Agreement.

How to reduce it?
1. Switch to Renewables
2. By energy efficient equipments
3. Change your diet
4. Go Digital
5. Reduce, Reuse, Recycle

• A carbon offset is a reduction in emissions of carbon dioxide or
greenhouse gases made in order to compensate for or to offset
an emission made elsewhere. One ton of carbon offset
represents the reduction of one ton of carbon dioxide or its
equivalent in other greenhouse gases
• There are two markets for carbon offsets:
1. The larger compliance market
2. The smaller voluntary market

CARBON TRADING
21
Carbon trading is a market-based system aimed at reducing greenhouse
gases that contribute to global warming, particularly carbon dioxide emitted
by burning fossil fuels.

CARBON NEUTRAL
22
Businesses often speak about becoming carbon neutral. This means
they’re taking steps to remove the equivalent amount of CO2 to what’s
emitted through activities across their supply chains, by investing in
‘carbon sinks’ that absorb CO2.
Carbon sinks, such as forests or our oceans, absorb and store more carbon
from the atmosphere than they emit. Investment into their health is called
‘offsetting’ and allows companies to operate in good conscience, knowing
their emissions are balanced out.

CONCLUSION
• Measuring carbon footprint could be a great starting point for
those who care about their impact on the environment. It is
important to understand where your carbon emissions come
from as there may be a lot of surprises.
• By lowering your carbon footprint, you can help contribute to
the overall reduction of greenhouse gas emissions. In our fight
against climate change, everyone making small adjustments
can lead to big results.

25.
FUTURE PERSPECTIVE
• Carbon footprint has emerged as a strong mode of GHG expression.
• The Personal Carbon Footprint aims to measure the environmental
impact of an individual's activities. Its calculation allows you to
reduce or optimise your energy efficiency and change your
consumption habits to minimise its impact on the planet
