Introduction
This standard sets out the methodology and requirements for calculating and reporting energy consumption
and greenhouse gas (GHG) emissions in transport services. This first edition of the standard is primarily
focused on the energy consumption and GHG emissions associated with vehicles (used on land, water and in
the air) during the operational phase of the lifecycle. However, when calculating the energy consumption and
emissions associated with vehicles, account is also taken of the energy consumption and emissions
associated with the vehicle’s energy processes (exploitation, production and distribution of transport fuels).
This ensures the standard takes a "well-to-wheel" approach when undertaking calculations, and when making
declarations to transport service users.
The philosophy, contents, and structure adopted in the preparation of this standard seeks to make it widely
applicable across the transport sector (encompassing all modes impartially) and accessible to a very diverse
user group. Within this sector it is recognised that transport operations vary hugely, from multi-national
organisations operating multiple transport modes to deliver transport services across the globe, through to a
small local operator delivering a simple service to one user. In addition, the potential user group for this
standard is similarly diverse, and the monitoring of transport energy and emissions within organisations can
be at different levels of maturity and sophistication. Consequently, this first edition of the standard balances
the desire for absolute precision and scientific rigour with a degree of pragmatism in order to achieve, ease of
use, accessibility and encourage widespread use.
Use of this standard will provide a common approach and frameworks for the calculation and declaration of
energy consumption and emissions for transport services, ensures declarations have greater consistency and
transparency, and fully allocates energy and emissions to a vehicle’s payload.
It is anticipated that future editions of the standard may have a broader scope boundary, to include additional
aspects such as, transport terminals, transhipment activities, and other phases of the lifecycle.

1 Scope
This standard establishes a common methodology for the calculation, declaration and reporting on energy use
and greenhouse gas (GHG) emissions related to a transport service (of goods, passengers or both).
It specifies guidelines, general principles, definitions, system boundaries, calculation methods, apportionment
rules (allocation) and data recommendations, with the objective to promote standardized, accurate, credible
and verifiable declarations, regarding energy use and GHG emissions related to any transport service
quantified.
Potential users of this standard are any person or organisation who needs to refer to a standardized
methodology when communicating the results of the quantification of a transport service, especially:
 Transport service operators (freight or passengers carriers);
 Transport service organizers (carriers subcontracting transport operations, freight forwarders and travel
agencies);
 Transport services buyers (shippers and passengers).

2.2 Specific terms
2.2.1
transport service
service provided to a beneficiary for the transport of a cargo or a person from a departure point to a
destination point
NOTE The beneficiary is named “transport service user”; see definition 2.2.5
2.2.2
leg (of a transport service)
for a transport service of a cargo or a passenger, section of the route taken within which the cargo or the
passenger is carried on the same means of transport
2.2.3
transport service operator
entity who operates transport services
NOTE A transport service operator can be a passenger’s carrier (acting directly for passengers or as sub contractor
of a transport service organizer), a freight carrier (acting directly for shippers or as sub contractor of a transport service
organizer).
2.2.4
transport service organizer
entity who provides transport services that are subcontracted to another entity (transport service operator)
who operates them
NOTE A transport service organizer can be a freight forwarder, an entity organizing trips/travel (e.g.: travel agency,
tours operator), a local authority responsible of public passenger transport
2.2.5

NOTE A transport service user can be a passenger, a shipper, or a transport service organizer (for the transport
services sub contracted to transport service operators).
2.2.6
vehicle operation
functioning of one vehicle that is used for providing partially or totally one or more transport services for one or
several beneficiaries
2.2.7
vehicles operations system
VOS
consistent set of vehicles operations established by the user of the standard according to its own criteria
NOTE These systems can be more or less wide. An example of a narrow VOS is a single operation of one vehicle
between a loading point and an unloading point. An example of a wide VOS is the activity of the whole fleet of a transport
operator over one year.

oSIST prEN 16258:2011
prEN 16258:2011 (E)
2.2.10
transport operator fleet value
value established by the transport service operator on the basis of own measurements over a fleet
2.2.11
default value
external value of the transport service operator
2.2.12
process
activity using energy and/or emitting GHG
2.2.13
vehicle process
process taking place at the local level of a vehicle, corresponding to operation of main engines (for propulsion)
and auxiliary engines (like thermo equipment) of the vehicle
NOTE Within this standard, vehicle processes do not include all processes at the vehicle level. Examples of not
included processes: leakages of GHG that are not due to engine combustion, assistance to the vehicle with other devices
like tugboats for towing vessels in harbours and aircrafts tractors for planes in airports. See Clause 4.
2.2.14
energy process
operational process taking place upstream of the local level of the vehicle, needed for the energy carrier used
by the vehicle
NOTE 1 These processes can be, for fuels, extraction, cultivation, refining, transformation, transport and distribution of
energy at all steps of the production of the fuel used; for electricity, extraction and transport of primary energy,
transformation, power generation, losses in electricity grids.
NOTE 2 "Operational" means that only a part of the processes taking place upstream of the local level of the vehicle is
included. Examples of non-included processes are: the production or construction of extraction equipments, of transport
and distribution systems, of refinery systems, of enrichment systems, of power production plants, etc. so as their reuse,
recycle and scrap.
NOTE 3 Within this standard, the objective is to take into account the total operational upstream processes for each
energy carrier. Careful use of European Directives on fuels and electricity like Directive 2009/30/EC on Fuel Quality and
Directive 2009/72/EC on internal market in electricity can assist in meeting this objective. In this context it has to be
pointed out that calculations done in accordance with Directive 2009/72/EC could include only the upstream processes
from power plants to the customer.
2.2.15
great circle distance
theoretical shortest distance between any two points on the surface of the planet measured along a path on
