MEASURES TO REDUCE THE CO2-EMISSIONS FROM THE TRANSPORT SECTOR IN THE CITY OF STOCKHOLM

The city of Stockholm has taken the decision to freeze the exhausts of CO: at the 1990 level up to the year 2000 and to restrict the CO: emissions in the long run to achieve a long-term, sustainable development. Transek Consultants was commissioned to carry out an environmental impact analysis of a broad spectrum of possible actions to reduce the carbon dioxide emissions from the transportation sector within the city of Stockholm. With a cost-effectiveness analysis it will be possible to address the question: which measures are the most cost-efficient from the environmental point-of-view, i.e. in this case, which measures yield the highest reductions of the carbon dioxide exhausts per Swedish Krona spent? Many measures, whose costs mainly consist of administrative surveillance costs, yield the highest cost-efficiency - and well below the present target of 0.05 ECU per kg of CO: Such highly cost-efficient measures are: improved traffic signals (highest cost-efficiency of all studied measures); road pricing schemes (of various types); traffic calming measures; car pooling incentives in terms of High Occupancy Vehicle (HOV) lanes.
