Government officials have been quietly exploring how much carbon dioxide could be saved if the country reflooded its peat soils.
The answer was more than four million tonnes of carbon dioxide a year - more than Huntly's coal fired power station.
Keeping peat drained for dairy farming, mainly in Waikato, allows microbes into the soil where they release carbon built up over thousands of years, producing up to ten per cent of New Zealand's net greenhouse gas emissions.
Officials concluded reflooding peat bogs could cut the country's emissions at a cost of $40 per tonne of emissions - cheaper than the current market price of buying a tonne of carbon.
But that was on public conservation land. Privately owned farmland, where most emissions come from, is considered more sensitive b...
