Principles & definitions of a carbon
footprint
Within the UK it is estimated that
business activities account for about half
of all emissions
DEFRA SMALL BUSINESS USER GUIDE:
Guidance on how to measure and report
your greenhouse gas emissions
What are greenhouse gases?
Gases in the atmosphere that absorb and emit
radiation
Many greenhouse gases
occur naturally
Others result exclusively from
human industrial processes
• Carbon dioxide
CO2
• Hydrofluorocarbons
HFCs
• Methane
CH4
• Perfluorocarbons
PFCs
• Nitrous oxide
NO2
• Sulphur hexafluoride
SF6
• Water vapour
Recommendation:
Measure emissions from the six GHGs covered by the Kyoto
Protocol where relevant for your organisation
What is a carbon footprint?
Carbon footprint - The amount of greenhouse gases
emitted that your organisation is responsible for,
expressed in units of carbon dioxide equivalent
(CO2e)
Usually in tonnes emitted annually
Useful Definitions
Carbon Dioxide equivalent – the unit for comparing
the ability of other GHGs to change the climate to
the ability of CO2 to change the climate,
i.e. Methane is 21 times better at absorbing the
sun’s energy than CO2 and N2O is about 300
times more effective than CO2.
But CO2 is more abundant!
Why measure your carbon footprint?
•

•
Legal compliance – CRC EUETS CCA MER
Compensation – offsetting
Win business / funding
Required by potential clients
Motivating for staff – report performance
Don’t measure, can’t manage
To set an overall reduction target
Report to stakeholders
Reputation / publicity
The consumption of electricity
The consumption of fossil fuels
in owned transport
The disposal of waste
The consumption of fossil fuels
(boilers, furnaces, etc)
The use & disposal of water
Staff commuting
What are the sources of GHG emissions caused by your organisation’s
operations?
Bio-mass / bio-fuels
Travel for business purposes
Fugitive emissions – i.e. leakage
of refrigerant
Embedded carbon in materials
Supply chain emissions
Process emissions
The use of imported heat &
steam
Emissions Scopes
1
2
3
Scope 1 (Direct emissions): Activities owned or controlled by your
organisation that release emissions directly into the atmosphere
Scope 2 (Energy indirect): Emissions being released into the
atmosphere associated with your consumption of purchased
electricity, heat, steam and cooling. Emissions do not occur on
site.
Scope 3 (Other indirect): Emissions that are a consequence of
your actions, which occur at sources which you do not own or
control and which are not classed as scope 2 emissions
Emissions Scopes
Recommendation:
Recommended: Measure and calculate emissions that fall into scopes 1
and 2
Discretionary: Measure and calculate your significant scope 3
emissions
Identifying the boundary of your footprint at
the organisation level
Organisational boundary defines which parts of the organisation will be included in
the emissions measurement and how to incorporate emissions from joint venture
and subsidiaries.
Recommendation:
Option 1: Equity share or % of ownership approach - % of

and calculate your organisation’s total emissions on

Option 2: Control approach – regardless of financial stake, take 100%
responsibility for emissions. Choose from:

organisations this will be the financial control approach
– Operational control approach: the full authority to introduce and
implement its operating policies.
Identifying the operational boundary of your carbon
footprint
Defining the operational boundary involves identifying which emission
sources within the organisation boundary to include in the
measurement.
Can be set by schemes such as CRCEES, Carbon Trust Standard, MER,
10:10 campaign, etc
Exercise 1: identifying the boundary

•
Working in groups

Recommendation:

acquisitions, discovery of significant errors
Activity data and conversion factors
Activity Data – some common questions
• What data will you need?
• How will you get this data?
• How can you make sense of energy bills?
What data will you need?
• Any data on the things that your organisation does
that results in a GHG emission or removal, for
example:
– Amount of electricity in kWh
– Amount of fuel consumed – either in litres (preferred) or using proxy data
(vehicle type and mileage)
– Scope 3 transport e.g. long haul flight mileage
• Try to collect data on volume or mass as its more
accurate
• Aim to capture at least 90% of your organisation’s
carbon footprint
How will you get this data?
• Utilities bills (gas, electric, water, waste)
• Monitoring utilities use
(daily, weekly, monthly, quarterly)
• Staff surveys (e.g. commuting)
• Purchase invoices (e.g. £’s spent on paper)
• From appliance model specification (e.g. refrigerant
leakage)
• Information from contractors – waste and recycling
N.B. Data will need to be converted in to correct format
How will you get data? Tips for
dealing with Landlords
• Legal right to information if Landlord recovers costs via a
service charge
• Big sites – mandatory half hourly data
• Negotiation on lease arrangements (in current climate)
• Read your own meters – Landlord should allow access to
meter or bills. Elec (kWh) gas (convert from m3 to kWh)
• Automatic Meter Readings (AMRs)
Activity Data – some more common
questions
• What do you do if you have missing data?
• What do you do if you have data in the wrong
format?
• When should you collect data?
What do you do if you have missing
data?
• Use best guess data – e.g. 2011 data if no 2012 data
available
• Take an average – e.g. average monthly use if missing
a few months data (beware of season)
• Worst case scenario take benchmark and multiply by
floor area
Record any methodology in carbon footprint report and
aim for complete data collection next year.
What do you do if you have data in
the wrong format?
• DEFRA tool accepts different data formats
(e.g. miles, Km’s and litres)
• Use conversion tables to convert into necessary
format (e.g. therms to kWh)
• Use proxy data (e.g. miles travelled and vehicle type
vs actual fuel consumption)
When should you collect data?
• Use the financial year (your organisation’s)
• Select the earliest data you can get for your first
carbon footprint – your baseline
• Beware of time lag for information collection.
Definition
Emissions conversion factors
The factors that we use to tell us how much carbon
has been emitted from our activities, i.e. consuming 1
kWh of electricity emits 0.51694kgs/CO2, or
0.52037kgs/CO2e (2012)
Published for the UK by DEFRA, updated annually.
These are unique for each country.

Reporting
Reporting
• Consider who the report is for, how will they use
it? (this affects what you put in it) –
Recommendation:
– to make decisions i.e. on investment or project
approvals
your
report would
to include
Select and
report- on
a baseline
yearneed
which
should be the
associated costs and a note on its accuracy
earliest date for which verifiable emissions data is available
– to report performance internally / externally - your
report would need to provide the information needed
by others and be written in a way that they can follow
– for further analysis - your report might need to contain
more of the raw data rather than a simple summary

You may report net emissions after offsets and green tarriff
You may use an appropriate intensity ratio to compare
performance over time
