Expert Panel Documents


The current workplan is:

  • Complete new methodologies for fertiliser NH3 emission

  • Discuss crop NH3 emissions, NMVOC emissions, soil NOx emissions with the modelling community 

  • Complete guidance on reporting emissions from anaerobic digestion

  • Continue and intensify the collaboration with TFRN (EPMAN/EPNB)

  • Assess need for methodologies for marine NH3 emissions and indirect NO emissions 

  • Liaise with IPCC revision of agricultural sector

Expert Panel Meetings

Online workshop,  16 Nov 2021


A workshop on ammonia abatement measures and how to reflect their effects in national emission inventories was organised by the EU TAIEX-EIR Peer 2 Peer and the Danish Ministry of Environment. The presentations made at this workshop are available HERE.

2021 Meeting held virtually, 4 May 2021


This will be the second year in which we have been obliged to hold our meeting online. Online meetings have the advantage that more people can attend, since the cost of time, travel and accommodation are far lower than face-to-face meetings. In addition, we can avoid the disadvantages associated with the expert panel meetings being in parallel sessions. However, there are also a number of disadvantages and these include the need to constrain meetings to about 1.5 hours, to avoid both the presenters and the audience becoming exhausted. When TFEIP meets face-to-face, the duration of the expert panel sessions is normally about 3 hours.


The cumulative effect of two years without face-to-face meetings, combined with developments within the Gothenburg Protocol, mean that we have a backlog of issues to discuss. We have therefore decided to hold a separate online Agriculture and Nature Expert Panel meeting in November this year. The topics we foresee discussing at the meeting in November are:

  • Further developments of the methodology for calculating ammonia emissions from field-applied animal slurry.

  • Further developments of the methodology for calculating ammonia emissions from applications of synthetic nitrogen fertiliser.

  • Ammonia emissions from crops and crop residues.

The agenda for the May meeting is as follows:

2020 Meeting held virtually, 11-14 May 2020

2019 Meeting held in Thessaloniki, Greece 13-14 May 2019
