The document discusses several greenhouse gases including methane, carbon dioxide, carbon monoxide, ozone, and nitrous oxide. It provides their chemical formulas and main sources and contributions to greenhouse gas emissions in New Zealand. Methane makes up 37% of emissions primarily from livestock, while carbon dioxide contributed the largest proportion in 2010 from fossil fuel combustion. Nitrous oxide accounts for 18% of emissions from animal waste and fertilizers used on farmland.

2. Methane:
 Chemical formula CH4.
 The main component of natural gas.
 Caused by livestock “belching”.

3. Methane and New Zealand:
 Makes up 37% of greenhouse emissions.
 Due to large farmed livestock and low use
of fossil fuels for generating electricity.

4. Carbon Dioxide:
 Chemical Formula CO2.
 Contributed the largest proportion of total
emission in 2010.
 Carbon dioxide is produced by human
activities, primarily through the
combustion of fossil fuels.

5. Carbon Monoxide:
 Chemical Formula CO.
 A colourless, odourless, and tasteless gas.
 Can be toxic to humans and animals in
high concentrations.

6. Ozone:
 Chemical Formula O3
 Ozone is a form of oxygen generated by
reactions between sunlight and oxygen.

7. Ozone and New Zealand:
 Without the protection of the ozone layer,
any life here on earth would be unable to
survive.

8. Nitrous Oxide:
 Chemical Formula N2O.
 Commonly known as „laughing gas‟.

9. Nitrous Oxide and New Zealand:
 Makes up 18% of greenhouse gas
emissions.
 Is produced through the breakdown of
animal waste products and through the
nitrogenous fertilisers applied to
farmlands.
