The document discusses carbon footprints and their impact on the environment. It defines key terms like greenhouse gases, carbon footprint, and carbon equivalents. It provides facts about rising global temperatures and carbon dioxide levels. It also explains how to calculate organizational and product carbon footprints using emission factors. Finally, it offers tips for reducing carbon footprints through choices in energy use, transportation, shopping, and standard ISO 14067 for carbon footprint quantification and communication.

Today, China is the
world’s largest CO2 emitter
(27%) – accounting for
more than one-quarter of
emissions. This is followed
by the USA (15%); EU-28
(10%); India (7%); and
Russia (5%).

The world is not on-track
to meet its agreed target
of limiting warming to 2℃.
Under current policies,
expected warming will be
in the range 3.1-3.7℃.

8. Greenhouse gases are a category of compounds that can trap
heat in the atmosphere.
It helps the earth to be warmer ( If not, we will be freezing)
This group of gases is the main cause of the greenhouse effect.
When there is an increase in the amount of greenhouse gases in the
atmosphere, then the greenhouse effect also increases.
As a result, global warming ensues and further climate change.

radiation .
In order, the most abundant greenhouse gases in Earth's atmosphere
are:

11. • The total amount of greenhouse gases produced to
directly and indirectly support human activities, usually
expressed in equivalent tons of carbon di oxide (CO2).
• A carbon footprint is historically defined as the total set
of greenhouse gas emissions caused by an individual,
event, organization, or product, expressed as carbon
dioxide equivalent.

12. • Measured in tonnes of carbon dioxide equivalent (tCO2e)
• Carbon dioxide equivalent allows the different greenhouse gases to be compared on a like-
for-like basis relative to one unit of CO2.
• CO2e is calculated by multiplying the emissions of each of the six greenhouse gases by its
100 year global warming potential (GWP).

20. How to Mitigate Carbon Footprint ?
• General Tips
Use Renewable Resources to the maximum
Use vegetable-based and biodegradable products of all kinds
No plastic or paper disposable cups. Bring in a mug or a
glass from home, and wash it regularly

21. How to Mitigate Carbon Footprint ?
• General Tips
Avoid taking more Printouts. Go Digital & Go Online
(eg. Banks, Cinema Tickets, Transport tickets)
Shut down everything when you leave or when not in use
( Be it in Home or in Office )

22. How to Mitigate Carbon Footprint ?
• General Tips
Use LEDs in place of Fluorescent Tubes
Use natural air ventilation as maximum as possible.
Fill your dish washer and washing machine with a full
load - this will save you water, electricity, and washing powder

24. How to Mitigate Carbon Footprint ?
• Travel Tips
Carpool - get a lift to school or work with a friend.
Use the bus or a train rather than your car.
For short journeys either walk or cycle.
Try to reduce the number of flights you take.
See if your employer will allow you to work from home one day a
week.
When staying in a hotel - turn the lights and air-conditioning off
when you leave your hotel room, and ask for your room towels to be
washed every other day, rather than every day.

25. ISO 14067 :2018 Standard
• Carbon footprint of products: Requirements and guidelines for quantification and
communication
• Developed to increase transparency in quantifying and reporting CO2 emissions over the
entire lifecycle of products and services – from production to recycling or waste disposal
• To effectively reduce greenhouse gas emissions, one must first identify their sources
• The carbon footprint concept highlights the contribution of individual products to the
greenhouse effect.
• The standard also covers communication of carbon footprint data to consumers.
