The SFT reckons that 50% of Norway's commitments can be implemented domestically at less than NKr200 per tonne of CO2-equivalent. The government is committed to a maximum 1% increase in greenhouse gas emissions over 1990 levels in the period 2008-2012. Latest projections suggest that emissions will increase by 24% by 2010, which means that "Norway must reduce its annual emissions by about 12m tonnes CO2[-equivalent]".
Cost projections are further complicated - and would sharply increase - if controversial plans to build a number of natural gas power stations are taken into account, and according to whether any such installations would include CO2 cleansing equipment.
The SFT looked at over 70 sources of greenhouse gas emissions and calculated annual emission reductions based on the maximum cost of NKr200 per tonne of CO2-equivalent. The main ones are: process industries, 1.6m tonnes; other process emissions, including landfill sites (CH4), refrigerants (HFCs) and oil products (VOCs), 1.2m tonnes; stationary combustion of fuel oils outside of process industries, 2m tonnes; mobile sources including road traffic, 0.7m tonnes; and shipping, small craft and aviation, 0.25m tonnes.
Tasks for the process industries would include phasing out the use of sulphur hexafluoride (SF6) in magnesium production and rebuilding plants to reduce nitrous oxide (N2O) emissions from the manufacture of nitric acid.
