  1. 1. ORDO AB CHAO : Den politiska historien om biodrivmedel i den Europeiska Unionen – Aktörer, nätverk och strategier

    Sammanfattning : Biodrivmedel blev efter millennieskiftet en alltmer prioriterad energikälla för EU och ansågs kunna stävja både klimathot och energissäkerhetsproblem samtidigt som drivmedelsproduktionen skulle gynna sysselsättningen i jordbruket. EUkommissionen formulerade 2007 ett mål om att ersätta 10 % av transportenergin till biodrivmedel. LÄS MER

  3. 2. Adding Fuel to the Fire : North-South dynamics in the geographies of transport energy: the case of EU biofuels

    Sammanfattning : Since the 2000s, the European Union (EU) has promoted biofuels for transport to achieve climate change mitigation, and rural development in the global South. In contrast, critiques have argued that biofuel promotion impedes more meaningful mitigation while also resulting in dispossession of land and loss of labour opportunities in the global South.

    Sammanfattning : This thesis investigate Swedish policy-making concerning promotion of wood gas and ethanol distilled from fermented sulphite lye as domestic fuel alternatives in the Interwar years and World War II. With a departure point in the theories of social constructions of technology (SCOT), the sociology of expectations and Thomas P. LÄS MER

    Sammanfattning : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. LÄS MER

  7. 5. Conditions for resource-efficient production of biofuels for transport in Sweden

    Författare :Carolina Ersson; Mats Eklund; Jonas Ammenberg; Mikael Lantz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Transportation has continued to increase worldwide and fossil-fuel dependency is strong which leads to a number of problems, e.g. increased emissions of green-house gases (GHG) and risks related to energy security. Biofuels have until now been one of the few renewable alternatives which have been able to replace fossil fuels on a large scale. LÄS MER
