EU emissions trading and the cement sector: a spatial competition analysis

An oligopoly competition model is described and used to illustrate the potential effect of EU emissions trading and transport issues on the production decisions and profitability of cement producers in a typical western European country market. The role of geography is introduced from three viewpoints: the existence of regional markets, the fact that EU producers may operate multiple plants across these regions, and the possibility of production capacity constraints. A typical EU state is divided into a coastal region which is initially exposed to international competition, and an inland region which is initially protected. Assuming pure auctioning of EU Allowances and a range of CO 2 prices up to €50/t, our model predicts a large increase of imports into the coastal region. Consequences for the inland producers include reduced attractiveness of the coastal market, as well as increased competition from coastal producers and from non-EU imports. The model includes a number of simplifications and therefore does not claim to offer definitive predictions, but our results do suggest that an increase in non-EU imports could feasibly offset more than 70% of the decrease in EU cement sector emissions. The likely impact on producer profits is considered for each region, and the advantages and disadvantages of potential mitigating policy measures are reviewed for either the EU Allowance allocation process or border adjustments on cement products.
