Enhanced data on greenhouse gas emissions from livestock shows agriculture is contributing fewer emissions than first thought.
Research conducted by AgResearch has expanded on the data gathered, has a more comprehensive breakdown on livestock types and pastoral conditions across the country and now includes the high country.
AgResearch senior scientist Tony Van der Weerden said data on nitrous oxide emissions from 10 years of additional field trials is now more accurate, particularly as it separates sheep and cattle.
Total emissions in New Zealand from sheep are 10.6 per cent lower than they were under the current emission factors, beef cattle emissions 5 per cent lower and dairy cattle emissions 1.4 per cent lower.
