Summary edit

Description
Français : Contributions aux émissions anthropiques de protoxyde d'azote (N2O) en 2005 (sous-secteurs).
Les sources de moindre importance (ex: eaux usées et aquaculture) figurent dans la barre du bas intitulée «Autres». Les barres de marges d'erreur (rouge) proviennent des estimations faites par l'EPA (US Environmental Protection Agency) (a), Davidson (b), Syakila et Kroeze (c) et de Crutzen et al. (d). La barre du haut représente le cumul des estimations et le cumul de leurs marges d'erreur individuelles. Ce total (largement dominé par les émissions agricoles) correspond à 30-40% environ de tout le N20 introduit annuellement dans l'atmosphère, le reste correspondant aux émissions naturelles.
English: Contributions to anthropogenic N2O emissions in 2005 (by-sectors) .

Error bars describes the range of leading estimates taken from US Environmental Protection Agency (a), Davidson (b), Syakila and Kroeze (c), and Crutzen et al.
