1. Project Overview Project Scope Task 1– Small-scale Combustion Task 2 – PM Inventory Estimates (Cond. & NRMM) Task 3 – Emission inv. estimates from Agriculture Task 4 – SO x / SO 2 and Black Carbon – Task 4.1 SO 2 and SO x metrics – Task 4.2 BC, EC and OC
1. Project Overview Approach 1.Review BC EFs in the GB –Verify whether the EFs are BC –Check internal consistency 2.Data Gathering –Consultation Document –Liaison with TFEIP, Workshop and other key groups –Targeted literature review 3.Update/extend BC EFs & text in the GB –Also collate information on EFs for both EC and OC 4.Where possible, derive EFs for BC, EC, OC 5.Handover of Chapters to the TFEIP.
1. Project Overview Overview of Project
2. Progress to Date Review of Current Guidebook Contents Most “BC” EFs are actually EC Initial review of GB shows some inconsistencies: –Energy & Combustion in Manufacturing (1A1 & 1A 2) – based on PM 2.5 inventory. –Road Transport (1A3b) - EC is assumed equal to BC –BC EFs for road vehicle Tyre, Brake wear and Surface wear (1A3bvi & vii) – based on TSP –Navigation (1A3d) - Lack et al.,(2009), includes results from EC, OC and BC but only with fuel splits.
3. Next Steps Next Steps Stakeholder Engagement (TFEIP, BC Workshop) –BC speciation in international methodologies? –Identify recent and ongoing research / literature platforms for updated sources, methods and emission factors Targeted literature review Draft guidebook updates –Text on speciation and definitions –BC speciation profile appendices –Consultation with stakeholders and research institutions
Summary & Close Consultation & Sourcing Data Publications within the last ~3 years Key sources: –USA –Nordic countries –TNO/IIASA Focus on BC EC, OC also of interest +44(0)
