The urgent need for a stronger climate change dimension to the CAP is emphasised by a report from the Food and Agriculture Organisation (FAO) which is a UN agnecy. If one takes account of everything from nomadic herds to processing plants, milk production accounts for 2.7 per cent of global greenhouse gas emissions. This rises to 4 per cent when meat processed from the dairy industry is added in.
Methane contributes most to the global warming impact of milk, accounting for 54 per cent of emissions. Nitrous oxide accounts for 27 per cent of emissions in developing countrues and 38 per cent in developing countries.
