In this paper, we use the Entropy Weight Method (EWM) to calculate the weights and TOPSIS Algorithm to calculate the score. Then, we made a preliminary comparison between the results of the two systems. Then, in order to obtain precise relation, we use Grey Correlation Analysis to reflect the correlation between variables. By comparing the grey correlation coefficient between different years and different countries, it is concluded that the correlation between GGDP and climate is higher than GDP. Due to the nature of cross-sectional data, we introduce time series data for the exploration of long-term trend. Through establishing the Grey System Prediction GM (1,1) model based on the grey system theory, we forecast GDP and GGDP of different countries from 2020 to 2024 which is based on the data from 2010-2019. We use multiple linear regression to predict carbon emissions, and present the results with the change trend of carbon emissions.

“…The gas-based thermal fault condition assessment technique plays a crucial role in this regard, as it monitors changes in the concentration of characteristic gas products in cables. [10][11][12][13][14][15] This enables the assessment of the cable's condition. Jianxin Yi et al successfully achieved early warning of electrical fires by detecting the characteristic substances released from overheated PVC cables.…”

Styrene grafted polypropylene (PP‐g‐St) is one of the insulating materials for high voltage power cables. However, the process of pyrolysis gas generation in polypropylene cable insulation remains poorly understood. To address this knowledge gap, this study employed a combination of thermogravimetric‐gas chromatography experiments, density functional theory, and reactive molecular dynamics simulations. The experimental findings revealed that the pyrolysis gases primarily consisted of H2, CO, C2H4, and CH4. Higher temperatures were found to increase the yields of H2 and CO. The simulation results indicated that H2 and CO were generated through the rupture of less reactive olefins and radicals, while C2H4 was primarily produced by the rupture of CC bonds in the polypropylene chain. Additionally, CH4 was formed when CH3 groups captured hydrogen from other molecules. By the chain reaction mechanism, we enable the calculation of the activation energy of PP‐g‐St. This study provides a theoretical foundation for understanding the pyrolysis gas generation.
