Agenda

AARHUSUNIVERSITY

3

›4B Manure Management

New NMVOC emission factors – Tier 1 and Tier 2 Update PM emission factors – Tier 1 and Tier 2

›4D Crop production and agricultural soils

Updated the NMVOC emission factor – Tier 1 Consistency of PM emission factor Updated NH3 emission factors from mineral fertiliser –

Tier 1 and Tier 2›4F Field burning of agricultural wastes

New/updated NMVOC emission factors - Tier 1 and 2

Revised chapters

AARHUSUNIVERSITY

4

›NMVOC - No existing default emission factors

›Few European data

›Large study undertaken in USA

mainly cattle, poultry and pigs housing not manure storage or field application

›Extrapolate to European conditions

›Likely to be a significant source

›Acceptance of emission factors but need for clearer presentation in Guidebook

4B Animal husbandary/manure management

AARHUSUNIVERSITY

5

›PM emissions

Incorrect references Incorrect emission factors Some missing emission factors

›Corrected errors

›Provided additional emission factors

›Accepted

4B Animal husbandary/manure management

AARHUSUNIVERSITY

6

›PM emissions

Error in emission factors

›Corrected errors

›Black carbon and copper – new Tier 1 and 2 emission factors

›Accepted

4F Field burning of agricultural wastes

AARHUSUNIVERSITY

7

›NMVOC emissions

Incorrect reference and units (Tier 1)

›Corrected error – new Tier 1 emission factor

›Accepted

4D Crop production and agricultural soils

AARHUSUNIVERSITY

8

›Ammonia emissions from fertilisers

Undocumented emission factors

›Literature review of ammonia emissions in the field

›No effect of temperature

›Effect of soil pH on ammonium sulphate and ammonium phosphate only

›Calculated new emission factors from data collated

›Significant decreases and increases in emission factors

›Large impact

4D Crop production and agricultural soils

AARHUSUNIVERSITY

9

›Accepted but need for

Some clarification concerning calculation of emission factors – email

Some improvements in description of methodologies Follow-up concerning ‘out-of-scope’ issues

›Incorporate in revised text or added to workplan

Revised chapters

AARHUSUNIVERSITY

10

› Proposed changes would result in aggregation/lack of detail

›Strategy:

Use the new CRF codes but add detail Retain the current structure as far as possible Require some clarification concerning details of CRF codes

Suggested changes to reporting codes

› Task Force on Reactive Nitrogen (TFRN)

Expert Panel on Mitigation of Agricultural Nitrogen (EPMAN) Expert Panel on Nitrogen Budgets (EPNB)

›TFRN expert panels contain experts in nitrogen emissions - source of expertise for TFEIP

› Maintain collaboration

Barbara Amon co-chair of Expert Panel on Mitigation of Agricultural Nitrogen

Agriculture and Nature/EPMAN/EPNB meeting

AARHUSUNIVERSITY

Workplan 2013-2014

Follow-up on discussions at Emission Inventory Compilers and Users Workshop

Ammonia emissions from crops

Continue discussion on harmonisation with revised reporting codes

Ensure that out-of-scope comments from selective GB revision are included in revised GB or added to workplan

AARHUSUNIVERSITY

Workplan 2013-2014 (cont)

Continue and intensify the collaboration with TFRN/EPMAN

Provide guidance on reporting emissions from anaerobically digested manure

Intensify the communication with EECCA countries on inventory preparation and mitigation options

Investigate better use of Emission Factor Database
