According to a Food Ingredients First column the Dairy Sector accounts for 4% of Greenhouse Gas Emissions.
The dairy sector accounts for around four percent of all global anthropogenic greenhouse gas emissions (GHG) according to a new FAO report. This figure includes both emissions associated with the production, processing and transportation of milk products as well as emissions related to meat produced from animals originating from the dairy system.
Considering just global milk production, processing and transportation and excluding meat production, the sector contributes 2.7 percent of global anthropogenic GHG emissions.
In 2007, the dairy sector emitted 1 969 million tonnes of carbon dioxide (CO2) equivalent, of which 1 328 million tonnes are attributed to milk, 151 million tonnes to meat from culled dairy animals, and 490 million tonnes from calves from the dairy sector that were raised for meat. The CO2 equivalent emission is a standard measurement for comparing emissions of different GHGs.
The global average of GHG emissions per kilogram of milk and related milk products is estimated at 2.4 kg CO2 equivalent.
