Research by the Scottish Agricultural College found that the farm is in an approximate carbon balance, with the processes releasing carbon into the atmosphere roughly balanced by processes that remove carbon and store it in the soil and vegetation. The College has produced a short research briefing note on 'Carbon footprint reporting for a Scottish livestock farm'. The project aimed to better understand the carbon footprint of a livestock farm in Scotland and to report baseline data against which changes in emissionscould be assessed; and
