Tradable black (CO2) and green (renewables) quotas gain in popularity and stringency within climate policies of many OECD countries. The overlapping regulation through both instruments, however, may have important adverse economic implications. Based on stylized theoretical analysis and...

In 2005, an EU-wide emissions trading scheme covering major CO2 producing sites shall come into power. The key objective of the trading scheme is to promote cost-efficiency of carbon reduction within the EU. We identify policy-relevant tradeoffs between overall efficiency, compensation and...

Political feasibility of emission trading systems may crucially depend on the free initial allocation of emission allowances to energy-intensive industries in order to ameliorate adverse production and employment effects. We investigate the potential trade-off between such compensation and...

We investigate the economic impacts of CO2 emissions pricing for Germany in the context of the Paris Agreement where we highlight the role of international market responses for the incidence across heterogeneous households. We consider three settings for international spillover effects: (i) a...

Energy markets and energy-intensive industries in all EU member states especially in Germany are subject to a diverse set of policies related to climate change. We analyse the potential efficiency losses from simultaneous application of emission taxes and emissions trading in qualitative and...

Carbon-based import tariffs are discussed as policy measures to reduce carbon leakage and increase the global cost-effectiveness of unilateral CO2 emission pricing. We assess how the potential of carbon tariffs to increase cost-effectiveness of unilateral climate policy depends on the magnitude...

In the context of climate protection policy it has been suggested that global CO2 emissions should be reduced significantly (contraction) and that per capita emissions should gradually be equalized across countries (convergence). This paper uses a dynamic multi-region computable general...

The allocation of emissions entitlements across countries is the single most controversial issue in international climate policy. Extreme positions within the policy debate range from entitlement based on current emission patterns (CEP) to equal-per-capita (EPC) allocations.Convergence (COV)...

This paper investigates the economic impacts of environmental tax reforms designed to reach given emission reduction targets for the German economy. Our focus is on the efficiency and employment implications of alternative schemes for emission tax differentiation between the production sector...
