Principles & definitions of a carbon footprint

Page 11: Carbon  Footprinting  Workshop

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

Page 12: Carbon  Footprinting  Workshop

What are greenhouse gases?

Many greenhouse gases occur naturally

Others result exclusively from human industrial processes

• Carbon dioxide CO2

• Methane CH4

• Nitrous oxide NO2

• Water vapour

• Hydrofluorocarbons HFCs • Perfluorocarbons PFCs• Sulphur hexafluoride SF6

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

Page 13: Carbon  Footprinting  Workshop

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

Page 14: Carbon  Footprinting  Workshop

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,

But CO2 is more abundant!

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.

Page 15: Carbon  Footprinting  Workshop

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

Page 16: Carbon  Footprinting  Workshop

What are the sources of GHG emissions caused by your organisation’s 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

Page 17: Carbon  Footprinting  Workshop

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

Page 18: Carbon  Footprinting  Workshop

Emissions Scopes

Recommendation: Recommended: Measure and calculate emissions that fall into scopes 1 and 2

Discretionary: Measure and calculate your significant scope 3 emissions

Page 19: Carbon  Footprinting  Workshop

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 organisation’s total emissions on a global basis

Page 20: Carbon  Footprinting  Workshop

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

Page 21: Carbon  Footprinting  Workshop

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

Page 23: Carbon  Footprinting  Workshop

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

Page 24: Carbon  Footprinting  Workshop

Activity data and conversion factors

Page 25: Carbon  Footprinting  Workshop

Activity Data – some common questions

• What data will you need?• How will you get this data?• How can you make sense of energy bills?

Page 26: Carbon  Footprinting  Workshop

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

Page 27: Carbon  Footprinting  Workshop

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

Page 28: Carbon  Footprinting  Workshop

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)

Page 29: Carbon  Footprinting  Workshop

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?

Page 30: Carbon  Footprinting  Workshop

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.

Page 31: Carbon  Footprinting  Workshop

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)

Page 32: Carbon  Footprinting  Workshop

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.

Page 33: Carbon  Footprinting  Workshop

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.

Page 34: Carbon  Footprinting  Workshop

Reporting

Page 46: Carbon  Footprinting  Workshop

Reporting

• 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

Page 47: Carbon  Footprinting  Workshop

Reporting cont…• Section 1: Description

– Purpose of report and approved uses– Boundaries – organisational and operational– Scope – what’s in, what’s 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 (3rd party?)• Other?

Page 48: Carbon  Footprinting  Workshop

Example Corporate Carbon Footprint from DEFRA

Recommendation: You should report total GHG emissions as a gross figure in tonnes of CO2e

You may report net emissions after offsets and green tarriff

You may use an appropriate intensity ratio to compare performance over time
