论文摘要
二氧化碳的人为排放必须很快接近零净 - 稳定全球平均温度。尽管一些国际协议提倡协调气候行动,但其实施仍低于预期。国际合作的主要挑战之一是社会政治接受的不同程度。在这里,我们询问了耦合的天然人类系统的简约模型,该模型代表了这种社会政治接受对清洁能源投资的影响和零排放的途径。我们表明,激励措施和碳定价是在达到关键二氧化碳浓度之前实现净零的必要工具,而对于快速有效的过渡,深度国际协调是必要的。尽管完美的协调情况仍然不可能,但由于近视经济策略和政策制度最终受到限制,该政策制度促进了自由骑行,更现实的分散合作,而每个演员的部分努力仍然可能导致大量减少发射。
Anthropogenic emissions of CO2 must soon approach net-zero to stabilize the global mean temperature. Although several international agreements have advocated for coordinated climate actions, their implementation has remained below expectations. One of the main challenges of international cooperation is the different degrees of socio-political acceptance of decarbonization. Here we interrogate a minimalistic model of the coupled natural-human system representing the impact of such socio-political acceptance on clean energy investments and the path to net-zero emissions. We show that incentives and carbon pricing are essential tools to achieve net-zero before critical CO2 concentrations are reached, and deep international coordination is necessary for a rapid and effective transition. Although a perfect coordination scenario remains unlikely, as investments in clean energy are ultimately limited by myopic economic strategies and a policy system that promotes free-riding, more realistic decentralized cooperation with partial efforts from each actor could still lead to significant emissions cuts.
