鉴于气候变化的经济影响和政策在各区域的分布不成比例，理解全球气候治理的影响对于实现可持续经济发展至关重要。我们估计了最新的损害函数，并构建了一个不确定性分析框架，以评估严格的气候政策是否会带来增长和不平等方面的经济利益。研究结果表明，尽管气候政策减缓了经济增长的步伐，但从长远来看，避免损害的好处可能会超过政策成本。此外，与2摄氏度相比，追求1.5摄氏度的目标在中短期内会减缓贫穷国家的经济追赶速度，但从长期来看会改善全球不平等状况。然而，当进入一个快速增长、以化石燃料为燃料的世界时，这种情况可能会改变，在这个世界中，不平等逐渐减少，但在2065年后开始上升。这项研究强调了将严格的1.5摄氏度目标与缓解经济不平等相结合的重要性。避免气候破坏的好处可能超过成本影响在本世纪晚些时候追求1.5摄氏度的目标可能会改善与2摄氏度相比的全球不平等长期而言，老挝等脆弱国家甚至可能更早地受益于1.5摄氏度快速经济增长导致不平等程度减少，但在2065年之后开始上升环境政策；能源；能源政策；经济
Understanding the implications of global climate governance is critical for achieving sustainable economic development, given that the economic impacts of climate change and policies are disproportionately distributed across regions. We estimate the updated damage functions and construct an uncertainty analysis framework to assess whether stringent climate policies entail economic benefits in terms of growth and inequality. The findings show that although climate policies slow the pace of economic growth, the benefits of avoided damage may overweight policy costs in the long run. Moreover, pursuing the 1.5°C goal slows economic catch-up of poor countries in the short to medium term relative to 2°C, but improves global inequality in the long run. This situation may, however, change when moving to a fast-growing and fossil-fueled world, in which inequalities gradually decline but start to rise after 2065. This study highlights the importance of synergizing the stringent 1.5°C goal with economic inequality alleviation. Benefits of avoiding climate damage may outweigh cost impacts later in the century Pursuing 1.5°C goal could improve global inequality compared to 2°C in the long run Vulnerable countries such as Laos could benefit from 1.5°C even earlier Rapid economic growth leads to inequalities decrease but start to rise after 2065 Environmental policy; Energy resources; Energy policy; Economics
