A French inventory of gaseous emissions (CH4, N2O, NH3) from livestock manure management using a mass-flow approach

Inventaire français des émissions gazeuses (CH4, N2O, NH3) liées à la gestion des déjections d'élevage utilisant une approche par bilan matière

Résumé

A new methodology based on (1) national data concerning livestock and rearing practices and (2) a mass-flow approach was developed to quantify ammonia (NH3), methane (CH4) and nitrous oxide (N2O) emissions resulting frommanure management in France. A literature review was performed to determine emission factors for each animal type and eachmanagement stage. A MicrosoftAccess® database containing these emission factors, the census data and manure compositions was then developed, allowing the calculation of gaseous emissions by the mass-flow approach. From this database, a national gas emissions inventory resulting from manure management was drawn up for the year 2003. Total NH3 emissions were estimated at 382 kt N, mainly arising from cattle (72%). Greenhouse gas emissions were estimated at 14.0 Tg CO2-eq. for N2O and 10.2 Tg CO2-eq. for CH4. Most of the N2O emissions occurred after the deposition of manure on soil during cattle grazing, while the CH4 was mainly produced during the period where cattle manure remained in livestock buildings and in outside storage facilities. Moreover, an evaluation of the uncertainty was performed considering the standard deviation obtained for the emission factors.
