Enteric methane emission of the Dutch dairy herd : Average and variation of enteric methane emission among the Dutch dairy herd

The Netherlands aims to reduce greenhouse gas emissions by 49% in 2030 compared to 1990. In order to achieve this goal the dairy sector needs to reduce methane (CH4) emissions by 1.0 megaton CO2-equivalents compared to 2017. Approximately 80% of the CH4 emission of the dairy sector originates from enteric CH4. The objectives of this study were therefore: 1) To gain insight into the average enteric CH4 emission and variation of the Dutch dairy herd, 2) to investigate which factors have an influence on the variation, and 3) to compare the measured CH4 emission per farm to the estimated emission...
