The price of EU allowances (EUAs) in the EU Emissions Trading Scheme (EU ETS) fell from almost 30€/tCO2 in mid-2008 to less than 5€/tCO2 in mid-2013. The sharp and persistent price decline has sparked intense debates both in academia and among policy-makers about the decisive allowance price...

The central pillar of European climate policy, the European Emissions Trading System (EU ETS), is currently under scrutiny, as the allowance price is persistently low at around 5€/tCO2. The cap was met and emissions actually declined in recent years, ensuring the environmental effectiveness of...

Long-term commitment is crucial for the dynamic efficiency of intertemporal cap-and-trade programs. Discretionary interventions in such programs could destabilize the market, and necessitate subsequent corrective interventions that instigate regulatory instability (Kydland and Prescott, 1977)....

The EU is currently preparing a major overhaul of its climate policy framework to deliver on the Green Deal’s new climate targets of a 55 percent cut in greenhouse gas (GHG) emissions relative to 1990 by 2030 and GHG neutrality by 2050. Extending and strengthening the role of carbon pricing,...

We analyze how conventional emissions trading schemes (ETS) can be modified by introducing ”clean-up certificates” to allow for a phase of net-negative emissions. Clean-up certificates bundle the permission to emit CO2 with the obligation for its removal. We show that demand for such...
