In this report, the Commissioner examines the issue of agricultural greenhouse gases – methane and nitrous oxide – which together form about half of New Zealand’s greenhouse gas emissions. This high proportion of emissions coming from agriculture is a major challenge for New Zealand and a polarising issue.
What, if anything, should we do about the methane and nitrous oxide from agriculture? Efforts to answer this question will be more efficient and constructive with a common understanding of the basic science. This report aims to help develop that understanding.
