Accelerating the establishment of an intelligent monitoring and dynamic accounting system for carbon emissions is an important foundation work in the initial stage of the dual carbon work. The construction of a dual carbon digital monitoring service platform is conducive to significantly improve the carbon emission management capacity of governments at all levels and related entities. In this paper，a complete set of schemes，such as platform system architecture，platform system function design，disaster recovery design，visual design，database design and service capability design，are proposed during the development and design of the dual-carbon digital monitoring service platform. In the process of development and construction，it is necessary to strengthen multi-party collaboration，highlight the requirements of application scenarios，ensure the security and reliability of the platform，and strengthen the integration with the existing digital government platform.
