The article discusses the inadequacies of cost-benefit analysis (CBA) in evaluating climate policy, emphasizing the importance of worst-case scenarios in decision-making. It argues that drastic emission reductions are necessary despite uncertainties and highlights the rapidly decreasing costs of clean energy as a positive development. The author critiques CBA for oversimplifying complex climate risks and stresses the urgent need for proactive climate action.

“ Introduction to Climate Change Economics

In the realm of uncertain and extreme risks, policy decisions should be guided by the worst-case outcomes rather than the most likely scenarios. This approach mirrors how individuals purchase insurance, protecting against unlikely but catastrophic events. For climate change, the potential worst-case scenarios are too severe to overlook.

“ The Limitations of Cost-Benefit Analysis

One of the most promising developments in climate policy is the rapid decline in the costs of clean energy technologies. Wind and solar power are becoming more affordable than fossil fuels, making the transition to renewable energy not only feasible but economically advantageous. This section discusses the implications of these cost reductions.

“ The Importance of Emission Reduction

The social cost of carbon (SCC) quantifies the economic damages associated with carbon emissions. However, the uncertainties surrounding climate damages complicate the estimation of SCC. This section explores how these uncertainties can distort policy decisions and the importance of considering a range of potential outcomes.
