Abstract: This paper summarized the overall progress and achievements of the collaborative innovation pilots aimed at reducing pollution and carbon emissions， identified existing challenges， and proposed actionable insights. Currently， the pilots have demonstrated smooth progress and notable phased outcomes. Most pilot units have actively promoted breakthroughs in institutional and mechanism innovations， achieved substantial advancements in key sectors and critical areas， and implemented a series of synergistic measures， yielding institutional innovations and replicable practices. However， challenges persist， including fragmented interdepartmental collaboration， insufficient alignment of management systems， funding shortages for synergistic projects， and inadequate technological support. Recommendations included intensifying awareness campaigns on synergistic efficiency， establishing coordinated promotion mechanisms， accelerating the implementation of synergistic management systems， advancing core technology R&D， conducting progress evaluations， and amplifying publicity to foster broader adoption. Simultaneously， recommendations were proposed for expanding the second batch of pilot work， focusing on advancement strategies， types of pilot programs， and selection methods.
