To achieve the commitments to both carbon peaking and carbon neutrality, China should focus on those policies of significant impact on emissions reduction at the lowest cost. Launching the national carbon market with the power generation sector is a good start point in this direction. Since its...

Denmark has been a frontrunner in policies that reduce greenhouse gas emissions and now plans to cut emissions by 70% by 2030 from 1990 levels and to achieve carbon neutrality by 2050. Such ambition induces halving emissions from 2019 levels and making the same emission abatement effort in ten...

As widely recognized, human mankind stands before the most challenging problem of preventing anthropogenic climate change. As a response to this, the European Union advocates an ambitious climate policy mix. However, there is no consensus concerning the impact of stringent environmental policy...

A central question in climate policy is whether early investments in low-carbon technologies are a useful first step towards a more effective climate agreement in the future. We introduce a climate cooperation model with endogenous R&D investments where countries protect their international...

Deep decarbonisation requires large-scale irreversible investments throughout the next decade. Policymakers discuss Carbon Contracts for Differences (CCfDs) to incentivise such investments in the industry sector. CCfDs are contracts between a regulator and a firm that pay out the difference...

The optimal transition to a low-carbon economy must account for adjustment costs in switching from dirty to clean capital, technological progress, and economic and climatic shocks. We study the low-carbon transition using a dynamic stochastic general equilibrium model with emissions abatement...

We derive policy rules for a highly aggregated fossil-based world economy with two competing stochastic thresholds or tipping points. Current production generates emissions that add to a stock of GHGs that affect the probability distribution of hitting a climate threshold with severe...
