Toward integrated energy and materials policies? A case study on CO2 reduction in the Netherlands

Energy and material flows are closely related. The materials system is of major significance from a national energy and CO₂ point of view. Integrated energy and materials studies can show significant new policy options for energy savings and CO₂ emission reduction through materials system improvements, shown in a case study on long-term CO₂ emission reduction in the Netherlands. An integrated energy and materials system MARKAL model is used for this analysis. The results show that, on one hand, CO₂ emission reduction costs are significantly reduced in the integrated approach and, on the other hand, the materials system is significantly influenced by CO₂ emission reduction. Consideration of dynamic interactions results in better understanding of future developments in both energy and materials systems.
