'Research on climate change' Stopping climate change has turned out to be an immense challenge. Although denial of the problem seems to weaken somewhat, a serious hurdle to a solution is that many scientists and politicians are insufficiently focused on ultimate effectiveness of policies. We quantify the magnitude of the decarbonization challenge and discuss general solution strategies and policy instruments. We then look into the carbon emissions involved in a renewable energy transition, assess the effects of recessions on carbon emissions and discuss the trade-offs between economic growth and reducing carbon emissions. We zoom in on carbon pricing, listing classic and heterodox arguments in favor of it, dealing with effectiveness, efficiency, equity, national and international feasibility, and systemic effects. Complementary instruments and the reasons for their use are mentioned as well. On the basis of this, implications for the policy trajectory after the Paris international climate agreement are formulated.
