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? Many greenhouse gases occur naturally Others result exclusively from human industrial processes Carbon dioxide CO 2 Methane CH 4 Nitrous oxide NO 2 Water vapour Hydrofluorocarbons HFCs Perfluorocarbons PFCs Sulphur hexafluoride SF 6 Gases in the atmosphere that absorb and emit radiation 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 (CO 2 e) 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 CO 2 to change the climate, But CO2 is more abundant! i.e. Methane is 21 times better at absorbing the suns energy than CO2 and N2O is about 300 times more effective than CO2.
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 Dont measure, cant manage To set an overall reduction target Report to stakeholders Reputation / publicity
What are the sources of GHG emissions caused by your organisations operations? The consumption of fossil fuels in owned transport Fugitive emissions – i.e. leakage of refrigerant The use & disposal of water Travel for business purposes Staff commuting Bio-mass / bio-fuels The consumption of fossil fuels (boilers, furnaces, etc) Process emissions The use of imported heat & steam The consumption of electricity Embedded carbon in materials Supply chain emissions The disposal of waste
Emissions Scopes 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 1 2 3
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. Option 1: Equity share or % of ownership approach - % of financial stake Option 2: Control approach – regardless of financial stake, take 100% responsibility for emissions. Choose from: – Financial control approach: the ability to control the financial and operating policies of the operation with a view to gaining economic benefits from its activities. – Operational control approach: the full authority to introduce and implement its operating policies. Recommendation: Apply your chosen approach consistently and for most organisations this will be the financial control approach Recommendation: Measure and calculate your organisations total emissions on a global basis
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 Read the case study Establish the boundary of the carbon footprint Establish which emissions sources occur within this boundary Split the emissions sources into scopes Answers & Discussion 10 minutes

Principles Recommendation: Develop a re-calculation policy for when your baseline and emissions will be re-calculated, for example, mergers, acquisitions, discovery of significant errors
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 organisations 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 m 3 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, Kms 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 organisations) 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.
Carbon conversion calculation e Activity Consumption of Electricity Consumption of Transport Fuel Unit kWh Electricity Litres Diesel Conversion 1 kWh X 0.5204kgs/CO 2 e 1 Litre x 2.584kgs/CO 2 e / by 1000 to convert to tonnes Result Greenhouse gas emissions (tnCO 2 e)
Main activity – Calculating the carbon footprint In your groups, using the laptop Open up the link titled DEFRA tool Calculate the consumption figures for each emissions source within the whole organisation boundary and then enter them into the right part of the tool Deal with uncertainty (there is some missing data) Add up the total CO 2 e and record this in the answer sheet provided in your packs (page 3) Note key decisions in method – these are needed for your report Answers & Discussion

Consider who the report is for, how will they use it? (this affects what you put in it) – – to make decisions i.e. on investment or project approvals - your report would need to include associated costs and a note on its accuracy – 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 – Etc Recommendation: Select and report on a baseline year which should be the earliest date for which verifiable emissions data is available
Reporting cont… Section 1: Description – Purpose of report and approved uses – Boundaries – organisational and operational – Scope – whats in, whats out, why – Time period and frequency of reporting Section 2: Method statement – The conversion factors and tools you used – Who provided data, what format it came in – What data was missing and why – Any assumptions made, filler calculations, etc Section 3: The Footprint – Totals of emissions by activity, scope, department, site, etc – Comparison with past footprints – how and why has it changed? – Benchmarks – mainly by site Section 4: Management – Current performance – scenarios & projections – will you meet your target? – Action plan(s) for reduction – key milestones for this year – Action plan for carbon management – training, data improvement, policy & strategy, resources Section 5: Verification statement (3 rd party?)
