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 careful heating of ammonium nitrate at about 250 C, which decomposes into nitrous oxide and water vapour. The addition of various phosphate salts favours formation of a purer gas at slightly lower temperatures. This reaction may be difficult to control, resulting in detonation. The decomposition of ammonium nitrate is also a common laboratory method for preparing the gas. Equivalently, it can be obtained by heating a mixture of sodium nitrate and ammonium sulfate: Another method involves the reaction of urea, nitric acid, and sulfuric acid: Direct oxidation of ammonia with a manganese dioxide-bismuth oxide catalyst has been reported: cf.
