Fonterra is among dairy organisations from around the world to sign a commitment to tackle greenhouse gas emissions from dairying.
The Global Dairy Agenda for Action on Climate Change was signed by the dairy co-operative on Thursday at the World Dairy Summit in Berlin.
Other signatories include the International Dairy Federation, the Global Dairy Platform and the European Dairy Association.
Fonterra general manager for sustainable production, John Hutchings, says the aim is to pool knowledge and resources to improve the technology and industry practices needed to reduce emissions.
He says it's important that the international dairy sector collaborates to find ways to reduce the impact of climate change.
Mr Hutchings says the work Fonterra has done suggests the industry in New Zealand is comparatively efficient, but that cannot be proved until countries have a common method of measurement of greenhouse gas emissions.
The dairy industry agreement follows this week's announcement from the Government that it's pushing for a global alliance for research to cut greenhouse gas emissions from agriculture.
