“Key findings of the research are:
- The carbon footprint was 940g of CO2 equivalent per litre of liquid milk
- Around 85% of the greenhouse gases are emitted on the farm (59% of these are methane, 17% are carbon dioxide, and 24% are nitrous oxide)
- Processing/manufacturing accounts for 10% of total emissions
- Distribution accounts for 5% of total emissions
- Products requiring larger quantities of milk have a larger carbon footprint.
Mr Harris said completion of the study is also an important step towards getting carbon footprint measuring methodology agreed with key international dairy organisations and producers so that the dairy sector globally can contribute to reducing climate change.”
If available, I have not been able to find the actual study. It seems to me that a grazing situation would offer some reduction in greenhouse gases.
