NIWA scientists leading Aotearoa New Zealand’s MethaneSAT agricultural emissions science programme are gearing up for the launch of its satellite in coming weeks.
New Zealand researchers have contributed to the first ever stocktake of global greenhouse gas emissions.
A research project co-led by Blue Carbon Services and NIWA will aim to provide New Zealand’s first national estimate of natural kelp-carbon sequestration in the marine environment.
Dr Sara Mikaloff-Fletcher is looking to turn the internationally accepted science of monitoring greenhouse gas emissions upside down—and the rest of the world is watching closely.
CarbonWatch NZ is an internationally-recognised research programme that will enable New Zealand to make the right decisions for a zero carbon future.

Almost half of Aotearoa New Zealand’s CO2-equivalent greenhouse gas emissions come from agriculture. This is a much higher proportion than most other countries – globally, agricultural emissions average around 7.5% of a country’s total emissions.

CO2 levels measured at Baring Head

The graph shows carbon dioxide (CO2) levels measured at Baring Head, NIWA’s clean air station, near Wellington. This station has been running since 1972 and is home to the longest running continuous CO2 measurements in the Southern Hemisphere.

CarbonWatchNZ will address crucial carbon cycle questions in the three landscapes that are most important to New Zealand’s carbon balance: forest, grassland and urban environments.

Is ocean iron addition part of the solution to climate change? Cliff Law, NIWA explains: 

Ocean acidification is the name given to the lowering of pH of the oceans as a result of increasing carbon dioxide (CO2) in the atmosphere.
NIWA makes a range of trace gas data freely available on our FTP site.
NIWA makes available and regularly updates results from several greenhouse gas measurement projects.
CFCs have damaged the ozone layer and led to higher UV levels and increased health risks. Our role is to understand the causes and effects of ozone depletion, to inform the public of the risk.
NIWA has been using advanced scientific instruments to measure atmospheric trace gases and isotopes for over 30 years.
The greenhouse effect is a warming of the earth's surface and lower atmosphere caused by substances which let the sun's energy through to the ground but impede the passage of energy from the earth back into space.
Answers to a range of frequently asked, atmosphere-related questions, including 'what is a carbon sink?', 'what do people mean by a fart tax', and so forth.
