The Swedish Energy Agency has been instructed by the Government to assist the Environmental Protection Agency in preparing material for the third National Report to the Convention of Climate Change. ;The study shows that the Swedish energy and carbon dioxide taxation policy is the most effective measure for reducing carbon dioxide emissions, although other measures intended to encourage the efficiency of energy use and use of renewable energy also contribute. ;It is expected that, as a result of the various incentive programmes, carbon dioxide emissions will have been reduced by 3-4 million tonnes by 2000/2005, of which a significant part will have been reduced in other countries.
