Wellington, Sept 10 Reuters - The Government is relying on carbon-trading through its proposed emissions trading scheme (ETS) to help it meet a target of a 10 to 20 percent cut in carbon emissions on 1990 levels by 2020.

* New Zealand emissions breakdown by sector as at 2007

Agriculture - 48 Percent: Primarily methane emissions from cattle and sheep, which number about 10 million and 33 million respectively. New Zealand is unique among developed countries in having such a high proportion of emissions from agriculture, with the average for developed countries about 12 percent.

Energy - 43 Percent: Mainly transport (19 percent) and electricity generation (11 percent) and manufacturing (7 percent). Transport is mostly made up from burning fuel for cars and trucks while electricity generation is from power stations fuelled mostly by gas and coal. The country relies on hydro, geothermal and wind power to supply just over 60 percent of the

nation's electricity.

Industrial processes - 6 Percent: The bulk of this comes from the production of iron, steel and aluminium.

Waste - 2 percent

* New Zealand emissions breakdown by gases:

In 2007, New Zealand's total greenhouse gas emissions were

75.6 megatonnes of carbon dioxide equivalents (MTCO2-e)

Carbon dioxide - 47 percent (35.2 MtCO2-e): With 90 percent

coming from the energy sector.

Methane - 35 percent (26.6 MtCO2e): With 91 percent coming

from the agriculture sector.

Nitrous oxide - 17 percent (12.8 mtco2e) : with 96 percent

coming from the agriculture sector.

* Removals

Carbon removal under the land use, land-use change and

forestry (LULUCF) sector was about 32 percent of total emissions

in 2007, or 23.8 MtCO2-e, almost entirely due to carbon absorbed

by forests.
