	abstract = {Methane and nitrous oxide produced by farmed ruminants may cause  over one third of the potential greenhouse warming which can be  attributed to New Zealand. This is a result of high populations of  domestic ruminants (mainly sheep and cattle), and the large warming  potential of methane and nitrous oxide. New Zealand{\textquoteright}s total greenhouse  gas production is an insignificant component of the global total, but  this fact cannot be used as a reason to ignore New Zealand{\textquoteright}s  contribution. International negotiations have commenced with the aim of  producing a treaty to limit global greenhouse gas production by  ruminants in New Zealand, and identifies areas needing further research.  It concludes that; (1) the accuracy of estimate of greenhouse gas  emissions from agriculture needs to be improved; (2) technology to  reduce greenhouse gas emissions from ruminants should be developed for,  and applied to, New Zealand farming systems; and (3) that equitable  methods of implementing limitation policies need to be investigated.  },
