norway offsetting green house gasses

via the bbc:

Norway has announced plans to offset the greenhouse gases produced by public employees when they fly abroad by buying emissions credits.
[...]
The estimated cost of the scheme would be around 2.5 million kroner ($400,000, £200,000) per year [ed: that's it?], according to the Norwegian news agency NTB
[...]
Although the announcement was received favourably by some businesses and environmental groups, at least one organisation reacted with scepticism.

Norway's Nature and Youth environmental group said: "The government should first reduce its ambitions for the oil and gas sector in Norway, which accounts for a third of emissions of greenhouse gases."

Norway is the world's third largest oil exporter and a major exporter of natural gas.
