Expert Panel Documents


The current workplan is:

  • Complete new methodologies for fertiliser NH3 emission

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

  • Complete guidacne 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

Webinar on Ammonia emissions from crop residues, 5 Dec 2023


A methodology for calculating the ammonia emissions from crop residues was presented at the 2023 annual meeting of TFEIP in Oxford. We were asked to hold a webinar to go through the new methodology with inventory compilers. This webinar took place on 5 December, 2023, from 15.00 to 16.00 CET. The presentation is available here and the associated Excel spreadsheet is here.

2023 Meeting held in Oxford, 18 April 2023
