As Vietnam accelerates its digital transformation, data centers have quietly become essential infrastructure for the economy. However, behind this role lies a concerning reality: their development is running counter to the nation’s environmental commitments, particularly the “net-zero” target for 2050. The core issue lies in a legal vacuum. Vietnam's current legal framework, particularly the 2020 Law on Environmental Protection, was designed for traditional industries and lacks specialized regulations to manage the unique impacts of data centers. Key internationally recognized environmental performance indicators, such as Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE), are almost entirely absent from normative documents. The lack of synchronization among environmental, energy, and technical infrastructure standards has created a fragmented legal environment, diminishing the effectiveness of state governance. An analysis of international experience reveals that advanced nations have proactively established effective legal frameworks. The European Union and Germany apply mandatory regulations with clear roadmaps for PUE and renewable energy adoption. The State of California (USA) utilizes a procedural mechanism, compelling investors to demonstrate and propose measures to mitigate environmental impacts from the initial permitting stage. Meanwhile, Singapore implements a comprehensive state management strategy through its Green Data Centre Roadmap. Drawing from these lessons, this paper proposes a system of synchronized solutions for Vietnam. The objective is not merely to “control” negative impacts, but to construct an intelligent legal corridor that transforms green standards into a genuine competitive advantage, enabling Vietnam's digital infrastructure to develop robustly and sustainably.
