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
Sulfur hexafluoride the gas's large molar mass. Unlike helium, which has a molar mass of about 4 grams/mol and gives the voice a childish and a "chipmunk like" quality, has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, giving the voice a "demonic" quality when is inhaled. For comparison, the molar mass of air, which is about 80% nitrogen and 20% oxygen, is approximately 30 g/mol which leads to a speed of sound of 343 m/s. Sulfur hexafluoride has an anesthetic potency slightly lower than nitrous oxide. Sulfur
