    Sammanfattning : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.

  4. 13. Public Policy and the Governance of Biofuel Systems

    Författare :Lorenzo Di Lucia; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport; Biofuels; governance; policy; governability;

    Sammanfattning : The dependency of transport on oil fuels is responsible for risks of energy supply security, and local, regional and global environmental problems, including the emission of greenhouse gases affecting the Earth’s climate system. Biofuels attracted considerable attention in recent years as a solution to these problems. LÄS MER

  5. 14. Energy system perspectives on transport biofuel policies – a modelling analysis
