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
Low-carbon diet and rail releases carbon dioxide (CO2), the primary gas responsible for global warming. Chlorofluorocarbons (CFCs) are emitted from mechanical refrigerating and freezing mechanisms – both staples in food shipment and storage. Anthropogenic methane emission sources include agriculture (ruminants, manure management, wetland rice production), various other industries and landfills. Anthropogenic nitrous oxide sources include fertilizer, manure, crop residues and nitrogen-fixing crops production. Methane and nitrous oxide are also emitted in large amounts from natural sources. The 100-year global warming potentials of methane and nitrous oxide are recently estimated at 25 and 298 carbon dioxide equivalents, respectively. Steinfeld et al. estimate that
