Industrial energy policy characteristicsthe case of Sweden

• PBA (Project-Based Approach)

• No national energy targets for sectors

• Large degree of energy-intensive industry

Recent research related to policies the case of Sweden

• Evaluation of the Swedish energy audit program (for SMEs):2011-2014• Study on the EU 2020 primary energy target’s implications for Swedish

industry:2010• Development of e-tools for energy audits and energy management (for

SMEs):2010-2011• Design of the Swedish energy audit program (for SMEs):2010• Evaluation of industries within the program “Sustainable Municipalities”:(for

SMEs)2008-2011• STIND (STatistics in INDustry):2008-2010• Evaluation of project Highland(for SMEs):2006-2007
