New Zealand's largest exporter, Fonterra, says it will receive no protection under planned changes to the emissions trading scheme.

NZ will make progress on its agricultural emissions initiative in talks with the US in 10 days, Tim Groser said yesterday.

Greenpeace is trying to keep up pressure on Fonterra to limit its use of palm kernel feed with a public rally outside the Ports of Tauranga.

Farmers have described Greenpeace's occupation of an inbound cargo vessel as 'economic treason.'

Federated Farmers says agitation about dirty dairying has led farmers to import foreign concepts such as feed sheds.
