Carbon leakage is an issue of major interest in both academic and policy debates about the effectiveness of unilateral climate policy addressing global externalities. The debate is particularly salient in Europe, where the EU Emissions TradingSystem (EU ETS) covers emissions of many traded...

This paper empirically investigates the effect of the European Emission Trading Scheme (EU ETS) on cross-country investments. To avoid carbon leakage, the scheme allocates a number of free allowances to firms at risk of relocating investments in areas outside the EU ETS. To study this problem,...

International offset certificates trade at lower prices than European Union Allowances (EUAs), although they are substitutes within the EU Emissions Trading System (EU ETS) for CO2. Firms therefore had a strong incentive to use the cheaper certificates. However, a considerable number of firms...

For any emission trading system (ETS) with quantity-based endogenous supply of allowances, there exists a negative demand shock, e.g. induced by abatement policy, that increases aggregate supply and thus cumulative emissions. We prove this green paradox for a general model and then apply it to...
