Data for"How Climate Change Shapes Global Systemic Risk Transmission: A Complex Network Approach"

The data consists of two main segments: (1) financial market data spanning from 1998 to 2024, which is used to calculate systemic risk measures, and (2) climate risk data beginning from 2007, incorporating the CCPI to capture the influence of climate factors on tail risk contagion in global financial markets. Financial Data for Systemic Risk Calculation (1998-2024) To analyze systemic risk transmission across markets, we use daily closing prices from global stock indices , including major financial markets such as North America, Europe, and Asia. Due to some missing values in the initial dataset, data preprocessed was conducted, removing dates with a high proportion of missing values. After processing, a total of 40,343 daily data entries were selected. CCPI Data (2007-2024) In this study, we incorporate the CCPI as a measure to assess the influence of climate-related factors on systemic risk transmission across global financial markets. The CCPI, developed by Germanwatch, the New Climate Institute, and the Climate Action Network, evaluates the climate protection performance of over 60 countries, covering more than 90% of global greenhouse gas emissions. The index assesses countries on four main categories: GHG Emissions, Renewable Energy, Energy Use, and Climate Policy. These categories are weighted to form an overall CCPI score that reflects each country’s commitment and effectiveness in addressing climate change. Our dataset for financial returns spans from 1998 to 2024, while the CCPI data begins in 2007. To ensure consistency, we apply a matched time-window approach, aligning the CCPI data with the corresponding financial data from 2007 onward.
