Decision-making Modeling of Brownfield Redevelopment in the Context of Dual Carbon: The Case of Brownfield in Chengdu Industrial Zone

How to effectively utilize the existing brownfield sites within the city and propose scientific and reasonable brownfield reuse methods have become the key issues to inhibit the encroachment of the city into the carbon sink system and achieve the goal of "double carbon". This paper takes an industrial area brownfield redevelopment project in Chengdu, Sichuan Province as an example, introduces the WSR theory to construct a brownfield redevelopment evaluation index system, and establishes a brownfield redevelopment second-order SEM model in combination with the SEM model, and then discusses the brownfield redevelopment plan. The results of the study show that the most suitable direction of redevelopment for this brownfield redevelopment project is public service land, and during the implementation of the project, attention should be paid to the restoration of the relevant measurement indexes in the physical dimension, and to increase the disclosure of project information and publicity.
