Changing up farming practices could pay dividends in the long run.
The Climate Change Commission expects low-methane sheep, and fewer cows to help the country cut methane by 10 per cent by 2030.
It recommends herd sizes shrink by a further six per cent, on top of the eight per cent predicted.
Climate Change Minister James Shaw told Mike Hosking the report shows output remains the same and you can see that with the value of milk over the last two decades.
“That just keeps going up and up and up, and that’s because the sector has been incredibly innovative at driving up productivity and therefore increasing its profits.”
