From Policy Silos to Collaborative Action: How Digital Infrastructure Reshapes Urban Low-Carbon Governance

In the urban governance landscape of the 21st century, smart cities and carbon neutrality have become two core narratives. The former reshapes urban operational efficiency through data, algorithms, and connectivity, while the latter redefines the quality of development through emission boundaries and energy transition. However, in many governance systems, these two agendas fall under different administrative departments, each with its own performance indicators and project budgets. This "policy fragmentation" not only leads to resource misallocation but also institutionally dilutes the emission reduction potential that digital technologies should have delivered.

A study published in Frontiers in Environmental Science, based on the practice of a local government in China, reveals how digital infrastructure can become the "institutional adhesive" that breaks down governance silos. The researchers point out that the integration of smart cities and carbon neutrality is not simply a technological overlay, but requires redesigning the interfaces and processes of local governance—that is, "re-engineering" the urban governance system.

The Fragmentation Dilemma: Why Do Smart Cities and Carbon Targets Speak Past Each Other?

From the perspective of organizational sociology, the specialized division of labor among government departments inevitably creates information barriers. Smart cities are typically led by big data bureaus, industry and information technology departments, or urban planning agencies, focusing on technology deployment and digital services; carbon neutrality goals, on the other hand, tend to fall under development and reform commissions, ecological environment departments, or energy agencies, focusing on emissions accounting and green transition. The two differ significantly in policy instruments, time scales, and even performance indicators—the former pursues immediate efficiency, while the latter focuses on long-term emission reduction.

This separation is not unique to China. Even in the European Union, although the European Climate Law and the European Green Deal provide an overarching legal framework, coordination between digital and climate departments at the subnational level still depends on proactive governance efforts. For countries lacking a common policy framework, collaboration across departmental boundaries becomes an even more systemic challenge.

Digital Infrastructure: From Tool to Institution

The core finding of the study is that digital infrastructure is not merely a tool for improving service efficiency, but an institutional platform for reshaping governance relationships. In practice, Chinese local governments have developed three interrelated mechanisms:

First, the institutionalization of advanced data governance. Integrating urban operational data and carbon emission data into a unified digital governance framework, establishing cross-departmental data standards and sharing protocols. This means that data is no longer the "private asset" of departments, but the public infrastructure of the urban system.

Second, the formalization of cross-departmental coordination platforms. By establishing special task forces, joint offices, or digital coordination platforms, smart city and carbon neutrality goals are brought into the same decision-making cycle. This formalized arrangement is superior to ad hoc project collaboration, as it creates sustained space for policy alignment.

Third, the digitalization of low-carbon public services. Utilizing intelligent energy monitoring, carbon emission tracking, and public service platforms to embed carbon reduction behaviors into the daily operational processes of citizens and enterprises. Here, digital tools play the role not of "external supervisors" but of "process-embedded regulators."These three mechanisms together constitute a "governance operating system," enabling the development of smart cities to directly serve carbon reduction goals rather than merely running in parallel with them.

Implications for Global Urban Governance

The value of this research lies in its transcendence of the simple causal assessment of "how much carbon can smart cities reduce," instead addressing "how local governments can use institutional design to make digitalization serve carbon reduction." For countries advancing digital government and climate goals, there are at least three implications:

• Top-level design of digital governance must consider the interface with climate goals, avoiding the creation of new "data silos";
• Departmental coordination needs to be elevated from the "project level" to the "institutional level," with formal mechanisms ensuring continuity;
• The digitalization of low-carbon services should focus on user experience and process restructuring, rather than merely deploying sensors.

Of course, the research also reminds us that the environmental benefits of digital technology are not achieved automatically. In the absence of governance coordination, smart cities may instead increase energy consumption and electronic waste. Therefore, true "smartness" lies not only in technology, but also in institutional orchestration.

Conclusion: Toward a Collaborative Urban Future

When smart cities and carbon neutrality are no longer seen as two separate agendas, but as two sides of the same urban transformation strategy, the fragmentation of governance becomes the primary challenge. The practices of Chinese local governments show that by restructuring governance processes through digital infrastructure, policy fragmentation can be transformed into collaborative action. The core of this path is not technology itself, but using technology to redesign institutional interfaces.

For global cities, this may be the most replicable lesson: in an era of AI- and data-driven governance, the true competitive advantage lies not in how many smart devices one possesses, but in whether dispersed information and goals can be woven into a collaborative network.
