    Biofuels have raised controversy regarding their environmental, social, and economic sustainability. The complexity of biofuel decisions and investments by both industry and society requires integration of scientific knowledge, public information, and values from a diversity of sources. Environmental assessments can identify multiple impacts of different options. Open and collaborative knowledge creation can support decisions in two ways: by building trust and credibility and by developing more robust understanding of key issues. Open assessment is a decision-support method that allows widespread participation in a transparent and freely accessible process. In this article, we evaluate two open assessment case studies concerning biodiesel production. The evaluation compiles the participants’ views regarding the potential of the assessment process to influence decisions in terms of quality of content, applicability, efficiency, and openness. According to the evaluation, openness can be feasibly implemented and is much appreciated by participants. More experience using broad and active participation is needed for further development of methods and tools. However, the currently common practices of closed and disengaged processes limit decision making. In addition, suitable tools and practices, as well as the inclusion of participants with appropriate skills, are needed to facilitate open collaboration.

    Meteorological information and services supporting the various operations of air transport enable a safe, efficient and cost-effective operating environment for airspace users, air navigation service providers and air traffic management. The continuing pursuit towards an improved quality of observation, forecasting and decision support services is driven by an increasingly weather-sensitive society and growing impacts of hazardous weather events. This thesis provides an overview of the field of aeronautical meteorological research by introducing the organisations involved, global and regional strategies, impacts of weather on air transport, current state of the art in meteorological research and decision support systems serving air transport needs with a view of where the field should evolve next. This thesis is an attempt to highlight key findings and point the reader towards the direction of further research on the given topics. Research supporting air transport operations with the optimal use of weather information is a specialized field where advances are led by the needs of various airspace users. Research institutions for example in the United States have contributed greatly due to the severe weather impacts experienced by the National Airspace System (NAS), the ability of the Federal Aviation Aministration (FAA) and the National Oceanic and Atmospheric Administration (NOAA) to direct long-term funding to solve specific aviation-related research questions. The creation and maintenance of long-lived teams of scientists and engineers working together to produce end-toend solutions that meet the needs of the aviation industry is the key to improving meteorological information to aviation users while university research is typically shorter duration and typical does not result in operational systems. From a global perspective, research is yet to be organised in a way that would contribute to solving aviation issues beyond single research projects and/or programmes. There is a lot more the scientific community could do to develop tailored information to decision support systems used by the aviation sector, but it would require systematic investments and the establishment of research groups focusing on the applied science questions and technology transfer. This thesis provides an overview of recommended decision support system development topics with an outline of potential milestones.
