What has been done (1)

Based on standard Sector-Chapter templates• Zero order draft of four chapters (not road transport)

Flow diagrams and decision trees for each chapter

Proposals regarding Tier 1, Tier 2 and Tier 3 approaches

Proposals on origins of the emission factors

Some questions for stakeholders and external experts

What has been done (2)

Overview of approach (1)

Navigation, aviation and railways• Moving freight/passengers • Between relatively few “embarkation” points• Requires significant investment

Proposals regarding Tier 1, Tier 2 and Tier 3 approaches

• Tier 1 – Fuel usage • Tier 3 – Journey based (trip km [tonnes]) stratified by

power unit technology• Tier 2 – Journey based (trip km [tonnes]) assuming

an average power unit technology mix

Is this a sensible approach?

Overview of approach (2)

Typical decision tree

Supports methodological choice

Leads to the best method, depending on

• Available data• Key source or not

Harmonizes with IPCC

Start

Collect data ontrain numbers anddistances travelled

Apply Tier 1default EFs

based on fuelconsumption

Yes

Yes

Yes

No

No

No

Decision tree for Railways

Use Tier 3 EFs forkm travelled

stratified by enginetechnology & by train

size/loading

Use Tier 2 EFsfor average train size/ loading, and average

engine technology

Are dataon train kmstratified byengine typeavailable?

Are dataon numbers oftrains, start andfinish location

available?

Is this a key source?

Are detailsof train, make up loading andengine type available?

Yes

No

Overview of approach (4)

Other non-road equipment• Decentralised – many items and owners• Ranges from large (>250kW) to small (<5 kW)• Often not very significant

Proposals for activity regarding Tier 1 approach• Fuel usage – not viable• Is it incorporated within road transport? If so

systematic under-calculation• Use alternative metric• Area of land used for crops – to give estimate of

number of tractors• Index of production and of construction activity

What is a sensible approach?

Emission factors (1)

Aviation• Good for Tier 2 and Tier 3• No Tier 1 equivalent (but can be calculated)• For Tier 2 and 3 transpose distance tables into a

simple algorithm

Navigation• Good for Tier 1• Tier 3 available from EU European Shipping study• Infer Tier 2 from aggregation of Tier 3

What is a sensible approach?

Emission factors (2)

Other NRMM and Railways• Both covered in current B810 chapter• There is Tier 1 data but some is incorrect• Specific issues with Table 8.2 • Carried through into Table 8.7 where the change in

units has not been taken account of

Tier 2/3• Aim to use NRMM limits• Issue of different engine sizes, and equipment types

What is a sensible approach?
