In response to the national "carbon peak, carbon neutral" dual-carbon strategy, the park transformation and upgrading, to create a zero-carbon park is imperative. This paper studies the successful cases of zero-carbon parks in China and other countries, and summarizes the application of "digital twin", a cutting-edge technology in the construction of zero-carbon parks, which provides a digital solution for the intelligent operation and management of zero-carbon parks. In addition, this paper also collected and sorted out the existing domestic zero-carbon park policies related to digital twin technology, extracted the relevant zero-carbon park construction standards and regulations, so as to better play the advantages of digital twin technology and provide reference and demonstration for the construction of similar zero-carbon parks.
