Climate change & greenhouse gases

Our scientists are working to ensure that New Zealand has strategies to manage the risks and respond to opportunities that climate change offers for the environment, the economy and society.

A number of inter-related research programmes focus on reducing land-based greenhouse gas emissions. Unlike most developed countries, half of New Zealand’s greenhouse gas emissions are methane and nitrous oxide resulting from agricultural practices. As these gases are emitted at landscape scales and atmospheric concentrations are very low, there are high uncertainties in measurement.

Our research focuses on the following areas:

  • determining the processes and drivers regulating greenhouse gas emissions from grassland, shrubland and forest systems.
  • reducing uncertainties in measuring and scaling emissions and removals.
  • providing the modelling and analytical tools for assessing, scaling and reporting emissions at farm to national scales.
