Introduction
• More details on calculating a carbon footprint
• Scopes 1, 2 and 3
• Setting boundaries
• Examples of carbon footprints and energy
audits
• TEA/COFFEE BREAK!!

Carbon (CO2) footprinting – more details
• CO2 is the main thing we are measuring, but other GHGs (mostly carbon-
based) are also included, so it’s called ‘carbon’ footprinting
• There is currently no formal definition of ‘carbon footprint’
• Neither is there a formal method of measuring them, but there are several
protocols
• The currently most widely recognised one is by the World Resource Institute -
an independent environmental think tank of scientists, economists and policy
makers

Carbon footprinting – more details
What is the point of them?!
• Baseline measurement for comparison with yourself in the future
(improvement)
• Measurement for comparison with others
• Publication
So, factors needing to be considered are:
1. Relevance
2. Completeness
3. Consistency
4. Transparency
5. Accuracy

Carbon footprinting – more details
What do you actually do?
• Decide on what you are going to include
• Make measurements of energy use
• Convert to units of CO2eq
• Report
What emissions to include? Operational boundaries (Scope 1, 2, and 3)
Who’s emissions to include? Organisational boundaries

6. the Environment Centre (tEC)
you . your business .your community
Scope 1 – Direct Emissions
“direct emissions occur from sources that are owned or
controlled by the company”
Examples:
• On-site combustion (industrial process or heating)
• Owned vehicles – work travel, transport
• Direct chemical emissions (e.g. methane)
General practical application:
• Gas/oil bills for heating
• Fleet petrol/diesel bills for transport

7. the Environment Centre (tEC)
you . your business .your community
Scope 2 – Indirect Emissions
“accounts for GHG emissions from the generation of
purchased electricity used by the company”
• When electricity is generated, emissions occur at the power
stations
• Locally generated electricity (micro-generation or renewable)
does not count
General practical application:
• Electricity bills

8. the Environment Centre (tEC)
you . your business .your community
Scope 3 – Other Indirect Emissions
(put simply, an optional accounting scope which accounts for everything else!)
“emissions as a consequence of the activities of a company,
but occur from sources not controlled by the company”
Examples:
• Staff commuting
• Embodied carbon of all products purchased
• Energy used in transport and operating products
• Waste generated, transported and processed

9. the Environment Centre (tEC)

Setting boundaries
• Who’s emissions do you include?
• For a small business in one office/unit, it’s fairly simple
• For a multi-national with interests in many
subsidiaries, it is less clear what to include
Clearly define the purpose of the measurement

CO2 footprinting examples - tEC
We are an environmental charity based in two offices, and with an
LPG-fuel car and a diesel-fuel van
This is a quick carbon footprint of the operations based in the
Southampton office, done as an example

CO2 footprinting examples – tEC Scope 1
Direct emissions from the premises: gas boiler for heating
Calendar year total = 26,364 kWh of gas = 5.3 tCO2eq
Emissions from company-owned vehicle:
Petrol: 120 litres = 0.3 tCO2eq
LPG: 620 litres = 0.9 tCO2eq
Transport Total = 1.2 tCO2eq
Scope 1 Total = 6.5 tCO2eq

12. the Environment Centre (tEC)
you . your business .your community
CO2 footprinting examples – tEC Scope 2
Electricity used on the premises:
Calendar year total = 44,723 kWh of electricity = 22.4 tCO2eq
Scope 2 Total = 22.4 tCO2eq
A quick Scope 1 and 2 footprint of the Southampton part of our
operations is therefore:
28.8 tCO2eq

CO2 footprinting examples –
conference
A one-off, day long conference. Footprint calculated for the purpose of offsetting
Scope 1 – Direct Emissions
Gas used for heating the venue on the day, and in the preparation of food:
171 kg
Staff travel on conference business:
758 kg
Scope 2 – Indirect Emissions
Electricity used for lighting the venue on the day, and in powering equipment:
196 kg

Eco-Island conference – Scope 3
conference
Food miles – moving the food to the venue: 48 kg
Manufacture of products specifically for the conference: 229 kg
Delegate travel to the conference
– the conference is definitely responsible for this
– delegates filled in a questionnaire about their travel,
results were analysed and combined
Delegate travel emissions: 1568 kg

Group discussion
• Split up into groups by sector (see lists on tables)
• Discuss the following issues:
1) Which of your activities contributes most to
your carbon footprint?
2) Which areas of footprint do you think are
easiest to reduce?
• We will briefly discuss results with the larger group
