The social rate of discount is a crucial driver of the social cost of carbon (SCC), i.e. the expected present discounted value of marginal damages resulting from emitting one ton of carbon today. Policy makers should set carbon prices to the SCC using a carbon tax or a competitive permits...

Since the introduction of the European CO2 emissions trading system (EU ETS), the development of CO2 allowance prices is a new risk factor for enterprises taking part in this system. In this paper, we analyze how risk emerging from emissions trading can be considered in the stochastic profit and...

We demonstrate the advantages of a climate treaty based solely on rules for international permit markets when there is uncertainty about abatement costs and environmental damages. Such a ‘Rules Treaty’ comprises a scaling factor and a refunding rule. Each signatory can freely choose the...

Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices. We assume that the certificate price is...

This paper studies a dynamic stochastic general equilibrium model involving climate change. Our model allows for damages on economic growth resulting from global warming. In the calibration, we capture effects from climate change and feedback effects on the temperature dynamics. We solve for the...

Low and uncertain carbon prices are often stated as a major obstacle for industrial sector investments in technologies to deliver deep emissions reductions. Project-based carbon contracts underwritten by national governments could addressregulatory risk, lower financing costs and strengthen...

Climate policy needs to set incentives for actors who face imperfect, distorted markets and large uncertainties about the costs and benefits of abatement. Investors price uncertain assets according to their expected return and risk (carbon beta). We study carbon pricing and financial incentives...
