How New Zealand plans to tackle climate change: Taxing cow burps

George Moss walks through a landscape dotted with grassy knobs of volcanic rock, following a herd of cows meandering along a dirt trail to pasture after their second milking of the day.
His pedigree cows rank among New Zealand’s most productive cattle, the result of careful breeding and quality grazing land. Millions of years of volcanic activity in the area have created rich soils ideal for this kind of free-range, grass-fed farming, helping turn dairy cows into the country’s biggest export earners.
But the digestive processes of the livestock — basically, their burps — emit a powerful greenhouse gas called methane, and as a result, agriculture makes up half of the country’s emissions. Now, the island nation, dubbed the Saudi Arabia of milk for its dominant role in global dairy trade, faces a reckoning over how to balance the outsize contribution that ranchers make to the economy against New Zealand’s need to meet its greenhouse gas pledges.
