The Evaluation of Carbon Peak and Carbon Neutrality Industry Based on AHP-Entropy Weight Method

Abstract

In response to the carbon peak and carbon neutrality dual targets, an index evaluation system was established around green development and decarbonisation consisting of three directions: “driving force”, “state”, and “response”. It includes 16 indicators such as the number of low-carbon technology releases, the proportion of CO2 generated from the industrial process. After collecting several current methods of constructing an index evaluation system around green development, an index evaluation system for assessing the low carbon industry process was advocated in different cities. The defined AHP analytic hierarchy process (AHP)-entropy weight method was used to determine the weights of evaluated indicators, and the fuzzy comprehensive evaluation method was adopted to complete the quantitative evaluation of data. Finally, the model was applied to 31 provinces, cities and autonomous regions in China and work out the score matching each province. According to the overall score, the development of CPCN process 31 provinces is categorized into 5 levels. The results show that a level C and a level D dominating and the level D accounting for the most significant proportion (more than 50%). Only three provinces and cities achieved the outstanding level of A. The conclusion that the carbon peak and carbon neutrality development in our country is still relatively lagging at the current stage with uneven regional distribution matches the actual situation; therefore, it validates the reliability of the method. Based on the scoring relationships between different indicators in each region, the defects and resistance of low-carbon industrial development in some provinces should be analysed to provide a foundation for further accelerating the steps towards achieving carbon peak and carbon neutrality.
