In Holland, analyses of data of 12000 dairy farms shows that more intensive farms have a lower greenhouse gas emission than less intensive farms. On farms with the ten percent lowest emission the average milk production per hectare land was 19500 kilogram compared to 16600 kilogram on the other farms and the average milk production per cow 800 kilogram more higher than on the other farms. Also the ten percent farms with the lowest greenhouse gas emissions added 40 kilogram nitrogen per kilogram less to pasture land and their cows were 300 hours less on pasture.
