Jamie Mackay: The Country host on Fonterra aiming to reduce on-farm emissions by 30 percent in new scheme - Heather du Plessis-Allan Drive

Industry experts are 'cautiously optimistic' about Fonterra's plan to reduce on-farm emissions by 30 percent by 2030.

The dairy co-op has promised to utilise new technology, changes to farming practice and existing and new vegetation to remove carbon.

The Country's Jamie Mackay says a 30 percent reduction in 7 years is unlikely, based on current projections.
