Climate Change Response (Emissions Trading) Amendment Act 2008 Bill establishing the NZ ETS were separated into the Climate Change Response (Emissions Trading) Amendment bill. On 10 September 2008, the Climate Change Response (Emissions Trading) Amendment Act 2008 had its third reading in Parliament and was adopted 63 votes to 57 with support from the Green Party and New Zealand First. The Climate Change Response (Emissions Trading) Amendment Act 2008 received the royal assent on 25 September 2008. The proposed scheme was to cover all six greenhouse gases specified in the Kyoto Protocol, carbon dioxide (CO), methane (CH), nitrous oxide (NO), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF). It
Nitrous oxide runoff and leaching of fertilizers (25%), biomass burning (10%), fossil fuel combustion and industrial processes (10%), biological degradation of other nitrogen-containing atmospheric emissions (9%), and human sewage (5%). Agriculture enhances nitrous oxide production through soil cultivation, the use of nitrogen fertilisers, and animal waste handling. These activities stimulate naturally-occurring bacteria to produce more nitrous oxide. Nitrous oxide emissions from soil can be challenging to measure as they vary markedly over time and space, and the majority of a year's emissions may occur when conditions are favorable during "hot moments" and/or at favorable locations known as "hotspots". Among industrial emissions, the
