Key findings

  • New Zealand’s gross emissions have increased by 23.1 per cent since 1990.
  • Methane from dairy cattle digestive systems and carbon dioxide from road transport have contributed the most to this increase.
  • Between 2016 and 2017, gross emissions increased by 2.2 per cent, mainly from an increase in emissions from road transport and fossil fuel-generated electricity production.
  • Between 1990 and 2017, New Zealand’s gross methane emissions increased by 6.2 per cent.
  • The agriculture and energy sectors were the two largest contributors to New Zealand’s gross emissions, at 48.1 per cent and 40.7 per cent respectively in 2017.
  • The land use, land-use change and forestry (LULUCF) sector offset 29.6 per cent of New Zealand’s gross emissions in 2017.
  • New Zealand’s net emissions increased by 65 per cent between 1990 and 2017 due to the underlying increase in gross emissions and the increased volume of timber harvested from New Zealand’s plantation forest estate in 2017 compared with 1990.
  • In 2017, Tokelau was included as part of New Zealand’s greenhouse gas inventory for the first time, contributing 0.004 per cent to New Zealand’s gross emissions.
