Contents • 1. Structure of these sectors • 2. What has been done • 3. Overview of the approach • 4. Questions to the expert group
Guidebook: Structure 2 • NFR code Title SNAP code • 1.A.3 a Civil Aviation 0805…. • 1.A.3 b Road Transport 070…. • 1.A.3 c Railways 0802…. • 1.A.3 d National navigation (shipping) 0803…. • 1.A.3 e Pipeline compressors 010506
Guidebook: Structure 3 • NFR code Title SNAP code • 1.A.2 a - f Manufacturing Industries and Construction • Iron and steel, non-ferrous etc • Non-road mobile machinery 0808…. • 1.A.4 b ii Residential: Household & Gardening • (mobile) 0809…. • 1.A.4 c ii Agriculture/ Forestry/ Fishing 0806…. • Off-road vehicles 0807…. • 1.A.4 c iii National fishing 0803…. • 1.A.5 a Other, Mobile (including military, land 0801…. • based and recreational boats)
Guidebook: Structure 4 • Title NFR code • Civil Aviation 1.A.3 a • Road Transport 1.A.3 b • Railways 1.A.3 c • Navigation 1.A.3 d • Other non-road mobile 1.A.2 a-f, 1.A.4 b ii • machinery 1.A.4 c ii, 1.A.4 c iii • 1.A.5 a
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) • Typical flow diagram
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
Overview of approach (3) • NFR code Title SNAP code • 1.A.4 c ii Agriculture/ Forestry/ Fishing 0806…. • Off-road vehicles 0807…. • 1.A.2 a - f Manufacturing Industries and Construction • Iron and steel, non-ferrous etc • Non-road mobile machinery 0808…. • 1.A.4 c iii National fishing 0803…. • 1.A.5 a Other, Mobile (including military, land 0801…. • based and recreational boats) • 1.A.4 b ii Residential: Household & Gardening • (mobile) 0809….
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?
