Summary
The influence of climate change and other environmental issues on shipping increased recently. As a major global source of greenhouse gas emissions, shipping has received substantial attention. Market-based measures (MBMs), such as carbon taxes and carbon trading, have been proposed as effective tools for emission reduction. Hitherto, existing research on the application of such MBMs on the shipping industry is fragmented, and thus research conclusion rather inconclusive. To fill in this gap, this study synthesizes 45 quantitative studies on MBMs in the shipping industry. The main findings quantify the emission reduction effects of carbon taxes and carbon trading. Also, it investigates the heterogeneity across fuel types, vessel categories, and operational routes that conditions the effectiveness of MBMs, and identifies the route–vessel interaction effects that underscore the need for different carbon-pricing policy deigns. Finally, the study offers useful recommendations for future research and policy development on maritime decarbonization.
