Evaluation qualitative des principaux systèmes d'élevage et synthèse sur les facteurs d'émission à l'échelle européenne
Résumé
In response to an invitation to tender, Cemagref-Rennes offered to fulfil the two specific tasks set out: (a) the preparation, distribution and subsequent analysis of a questionnaire to establish the current manure management practice of livestock farms across the EU 27 and (b) supporting the project management of GGELS in the compilation of the best and most appropriate emission factors in this context.
