Abstract
The frequency, intensity and duration of extreme weather events have seriously affected human life and production. The electric power sector is the foundation of economic activity as well as a core participant in the adaptation and mitigation of climate change. Therefore, in the context of climate change, it is crucial for the stable operation of the national economy for power sector to cope with different climate change risks and improve their adaptability to climate change. In this paper, listed power companies in China are selected as samples to analyse the impact of climate change risk on the financial performance of the power system's supply and transmission-distribution sides. The empirical results show a significant positive correlation between climate change risks and the financial performance of listed electric power companies. The rainfall index and drought index positively impact the financial performance of listed electric power companies. The cryogenic freezing index has a negative impact on the financial performance of listed electric power companies., which is further analysed and proved that a cryogenic freezing disaster will cause the regional breakdown of the power system. The operating cost ratio and the proportion of clean energy supply play a mediating effect on the correlation between the comprehensive climate risk index and the return on equity of companies. To increase electric power companies' ability to adapt to climate change, climate change risks should be integrated into the risk management framework, and the company's financial performance can be improved by optimizing the energy mix and constructing safe lines. The government can promote the transformation of electric power companies by launching green financial tools.
期刊介绍:
Climate Risk Management publishes original scientific contributions, state-of-the-art reviews and reports of practical experience on the use of knowledge and information regarding the consequences of climate variability and climate change in decision and policy making on climate change responses from the near- to long-term.
The concept of climate risk management refers to activities and methods that are used by individuals, organizations, and institutions to facilitate climate-resilient decision-making. Its objective is to promote sustainable development by maximizing the beneficial impacts of climate change responses and minimizing negative impacts across the full spectrum of geographies and sectors that are potentially affected by the changing climate.
