Mr. Desmond Savage:

I said there is no cost-effective method of measurement. There are ways to measure. The likes of the Teagasc facility at Moorepark and UCD Lyons Farm in Kildare have invested in systems, including, for example, a green feed system which involves cattle going into a controlled environment and being monitored for four or five minutes. This is okay from the point of view of research and sampling but it is not a practical way of measuring methane emissions on a commercial beef or dairy farm.
