Compared to the EDGAR inventory, the HEI-CD model offered greater spatial resolution and precise point
source information, which was better suited for urban carbon monitoring and policy-making at the city
scale. The inventory will not only support the accurate inversion of CO emission flux but also serve as a
2
crucial tool for guiding effective carbon reduction strategies.

Future work should focus on further refining the inventory through the introduction of additional data
sources, enhancing validation systems, and ensuring adaptability to the dynamic nature of city
environments. This will solidify its role in supporting Chengdu and similar cities in their efforts toward
carbon neutrality.
