融资对于绿色能源转型至关重要，但由于各地区的资本成本差异很大，因此获得低成本融资的机会并不均衡。这项研究表明，发展中经济体的模型化脱碳途径如何受到不同加权平均资本成本（WACC）假设的不成比例的影响。例如，代表特定区域的WACC值表明，在非洲，成本最优的2 °C路径的绿色电力生产比忽略区域因素时低35%。此外，到2050年降低低碳和高碳技术水碳成本系数值的政策干预措施将使非洲比不考虑资本削减成本的情况提前约10年实现净零排放。当与气候相关的投资长期不足时，发展中经济体就会出现气候投资陷阱。目前的融资框架对这些资金流动构成障碍，需要进行根本性改革，以便更公平地分配资本。获得低成本融资对于发展中经济体向绿色能源过渡至关重要。在这里，作者展示了发展中经济体的脱碳路径模型如何受到不同加权平均资本成本（WACC）假设的不成比例的影响。
Finance is vital for the green energy transition, but access to low cost finance is uneven as the cost of capital differs substantially between regions. This study shows how modelled decarbonisation pathways for developing economies are disproportionately impacted by different weighted average cost of capital (WACC) assumptions. For example, representing regionally-specific WACC values indicates 35% lower green electricity production in Africa for a cost-optimal 2 °C pathway than when regional considerations are ignored. Moreover, policy interventions lowering WACC values for low-carbon and high-carbon technologies by 2050 would allow Africa to reach net-zero emissions approximately 10 years earlier than when the cost of capital reduction is not considered. A climate investment trap arises for developing economies when climate-related investments remain chronically insufficient. Current finance frameworks present barriers to these finance flows and radical changes are needed so that capital is more equitably distributed. Access to low cost finance is vital for developing economies’ transition to green energy. Here the authors show how modelled decarbonization pathways for developing economies are disproportionately impacted by different weighted average cost of capital (WACC) assumptions.
