This 2nd version of STREAM Freight Transport 2016 (January 2017) has the following changes relative to Version 1:
STREAM Freight Transport 2016 is a handbook providing emission factors per tonne-kilometre for road, rail, inland-waterway and short-sea transport. For each of these transport modes the report gives representative average emission data suitable for exploratory (policy) analyses for which average data suffice. In addition, the report provides detailed factors with which emissions can be calculated for specific situations by users disposing over information on the types of vehicle or vessel employed and their mode of utilization (type of freight and class of waterway/road). Besides fleet-average emission factors for the year 2014, factors are also reported for individual vehicle technologies (such as Euro emission classes) and (alternative) fuels.
Besides the emission data, the report also provides extensive information on the sources and methods used.
The emission factors in this publication are not designed for direct comparison of transport modes. What they can be used for is comparison between various transport options, allowing for the particular distance travelled by each mode, for upstream and downstream transport and for freight transhipment. This is illustrated with reference to several concrete cases.
STREAM provides emission factors for greenhouse gases (CO2, CH4 and N2O, summed as CO2-eq.) and the principal transport air-pollutants (PM10, NOx and SO2). Besides both exhaust and wear-and-tear emissions, the emissions occurring during extraction, production and transport/transmission of fuel and electricity are also reported.
