Dedicated to building a digital and intelligent low-carbon urban complex, we aim to construct a panoramic carbon emission monitoring "brain." Through IoT perception, data empowerment, smart decision-making, and trustworthy connections, we achieve comprehensive digital emission reduction from the government, parks/buildings, enterprises/institutions to the public. This deeply integrates low-carbon elements into the city's pulse, promoting efficient implementation of carbon neutrality policies and carbon reduction strategies, thereby assisting cities in achieving their carbon neutrality goals.
