Key energy figures and greenhouse gas emissions based on industry energy usage

Swedish industry should strategically work towards improved energy and resource efficiency. In this context, decision making, and key performance indicators (KPIs) play a central role in achieving improved efficiency. Even for regulation authorities, fair KPIs of energy end-use are very important to be able to perform excellent, preventive and proactive work towards Swedish companies. KPIs at international and national levels are based on energy supplied, normally related to an economic output, such as value added. However, there are no key figures about the energy end-use in Swedish industry, distributed on energy carriers such as electricity and oil, and in turn allocated on energy end-using processes such as furnaces, air compressors, etc. The existing figures regarding this are based on rough estimates. The goal of the project has therefore been to generate a process tree for several of the largest, energy end-using Swedish manufacturing industries, as regards how energy end-use is distributed at the process level and for different energy carriers, and in turn allocate greenhouse gas emissions for these different processes. The results indicate that energy KPIs based on energy use and indirect carbon greenhouse gas emissions at process level can contribute to better knowledge of the industrial energy end-use processes that have the greatest potential for energy efficiency improvements as well as greenhouse gas abatement. In order to continuously know the processes with the greatest potential for improvement, energy end-use data should be collected regularly and follow a standardized categorization of energy end-use processes. The project has been limited to Swedish industry, but the results can be useful for other EU member states as well as globally.
