What institutional conditions seem relevant for multi-sector environmental policy integration (EPI) and its outcomes? Analysing the Swedish bioenergy policy process, which represents a positive case of multi-sector environmental policy integration, it is argued that open actor access, use of environmental knowledge, monitoring mechanisms, and both environment-sectoral and inter-sectoral policy coordination are conducive for multi-sector environmental policy integration, which is also affected by external events. To achieve outcomes from multi-sector environmental policy integration, monitoring mechanisms as well as inter-sectoral policy coordination are important. Key words: environmental policy integration; multi-sector EPI; policy coordination; institutions; bioenergy
