在讨论社会如何减少温室气体排放时，交通部门往往被视为最困难的问题之一。此外，运输部门面临着与供应安全有关的问题。本文件的目的是提出基于可再生能源的公路运输系统的可能战略，并以瑞典为例说明如何设计这种系统以避免对进口的依赖。所考虑的需求方战略包括减少运输需求的措施，以及提高车辆燃料经济性的各种技术和非技术手段。在供应方面，讨论了利用可再生电力生产的生物燃料和合成燃料。进行计算，以确定这些措施对未来的瑞典公路运输部门可能产生的影响。研究结果强调了强有力的需求方措施的重要性，并表明，尽管生物燃料肯定能为独立于进口的公路运输部门做出重大贡献，但即使在瑞典这样的生物质丰富的国家，它们也远远不够。相反，根据这项研究，基于可再生电力的燃料必须满足道路运输部门一半以上的能源需求。
When discussing how society can decrease greenhouse gas emissions, the transport sector is often seen as posing one of the most difficult problems. In addition, the transport sector faces problems related to security of supply. The aim of this paper is to present possible strategies for a road transport system based on renewable energy sources and to illustrate how such a system could be designed to avoid dependency on imports, using Sweden as an example. The demand-side strategies considered include measures for decreasing the demand for transport, as well as various technical and non-technical means of improving vehicle fuel economy. On the supply side, biofuels and synthetic fuels produced from renewable electricity are discussed. Calculations are performed to ascertain the possible impact of these measures on the future Swedish road transport sector. The results underline the importance of powerful demand-side measures and show that although biofuels can certainly contribute significantly to an import-independent road transport sector, they are far from enough even in a biomass-rich country like Sweden. Instead, according to this study, fuels based on renewable electricity will have to cover more than half of the road transport sector’s energy demand.
