• ‘You can’t manage what you don’t measure’ - as true for carbon as it is for £
• Carbon emissions – transport is fastest growing source
• Understand your baseline• Prioritise actions for carbon

Scope
Establishing Your BaselineCarbon Footprint
A carbon footprint should follow five key principles:
RELEVANCE
TRANSPARENCY
PRAGMATISM
CONSISTENCY
ACCURATE/COMPARABLE
Normalise data
Establishing Your BaselineCarbon Footprint
Identification of Carbon Sources

Data issues
• In practice, data may not be available or be available in a form that needs some extrapolation
• What secondary data is needed if we don’t have the primary data?
In practice...Sources of travel
emissionsWhere to find data Units
Owned vehicles MOT certs, odometers, log books
Mile/km
Leased vehicles Lease company/fuel cards/receipts
Mile/km/litres
Public transport Expense claims, journey planners
Mile/km
Flights Journey planners, air miles, calculators, travel company, receipts

Commuting Commuter survey, staff postcodes

Data solutionsWhat do you do if you don’t
have Primary data?
Extrapolate from secondary/proxy data
Calculate Carbon FootprintWorkshop
• Use the table provided to identify:scope and sources of transport emissions within your
organisation,data that is available – mode, distance, fuel, otherx data that is not available
• If you can, calculate your organisation’s estimated transport carbon footprint
• Who has the lowest carbon footprint per km getting here?!
Workshop Session
2009/10 expenses record both mileage and cost for car travel. Public transport is hidden within ‘Miscellaneous Travel’.
Example

The relative proportion of business mileage costs for 2010/11 can be applied to total expenditure for previous years to estimate business mileage costs.
The known mileage rate can then be applied to costs to estimate distance travelled.
