Helsinki Region: A Forerunner for Clean Urban Transport

Buses operating in the Helsinki metropolitan area travel a total of about 83 million km each year. This article discusses how the environmental impact from bus fleet emissions can be mitigated through the use of biodiesel fuels. A Finnish company has developed a new process to produce synthetic second generation biodiesel fuel called NExBTL. This fuel can significantly reduce emissions in the existing fleet, with no need to modify vehicles or the refueling infrastructure. An agreement has been signed by Helsinki's public transportation authority, the metropolitan area council and the producer of NExBTL to implement a large-scale demonstration of the new biofuel in buses and refuse trucks. It is estimated that using 100% NExBTL in the entire bus fleet would reduce the external cost for the bus fleet by more than 30 percent.
