Balancing the Carbon Market: Overview of Carbon Price Estimates

by T. Bole

- One of the main conclusions of this study is that little modeling work has been done on very ambitious greenhouse gas reduction targets, which is of most relevance for climate policy. The few studies that do address the implications of achieving low stabilization levels (around 450 Parts per million by volume, ppmv, CO2-equivalent) on average estimate a carbon price of 52 $/tCO2, while those analyzing the costs of stabilization around 550 ppmv CO2-equivalent come to an average figure of 48 $/tCO2. The high standard deviation around the average estimate testifies to the large model and parameter uncertainties inherent to the modelling process and calls for cautious interpretation of modelling results, both when comparing the outcomes of different models and in their individual use.
