ISO/TR 37115-1:2026 Zero-Carbon City Standard Released

On April 23, 2026, the International Organization for Standardization (ISO) published ISO/TR 37115—1:2026, the first internationally recognized technical report on zero-carbon cities led by China. The standard documents eight Chinese city-level zero-carbon implementation cases—including Shenzhen, Xiong’an, and Hangzhou—and is already being referenced in new urban development procurement guidelines in the UAE, Chile, and Vietnam. Exporters of smart grid equipment, green building materials, and low-carbon transport systems stand to benefit from enhanced market access and upstream standard alignment.

Event Overview

The International Organization for Standardization (ISO) officially released ISO/TR 37115—1:2026 Cities and Communities — Sustainable Development — Zero-Carbon Cities — Part 1: Case Studies on April 23, 2026. This technical report was led by China and includes eight domestic zero-carbon urban practice cases: Shenzhen, Xiong’an New Area, Hangzhou, as well as five additional cities not named in the source information. As confirmed, the document has been formally adopted into technical procurement guidance for new city development projects in the United Arab Emirates, Chile, and Vietnam.

Impact on Specific Industry Segments

Export-oriented manufacturing enterprises
These companies produce smart grid equipment, green building materials, and low-carbon transport equipment. The adoption of ISO/TR 37115—1:2026 by foreign governments signals a de facto alignment requirement for tender eligibility in infrastructure projects. Impact manifests in bid documentation compliance, certification pathways, and prequalification criteria—particularly where national procurement rules now reference this ISO technical report.

Supply chain service providers
Firms offering conformity assessment, third-party verification, or international certification support may see increased demand for services tied to zero-carbon city compliance frameworks. Since the standard is structured as a case-based technical report—not a certifiable management standard—impact centers on advisory capacity rather than formal accreditation scope expansion.

Domestic green infrastructure project developers
Chinese developers engaged in overseas EPC or turnkey urban infrastructure contracts may encounter revised technical annexes in RFPs referencing ISO/TR 37115—1:2026. The inclusion of Chinese city cases implies that design specifications, performance metrics, and reporting formats modeled on those cases could gain preferential treatment in evaluation scoring.

What Relevant Enterprises or Practitioners Should Monitor and Do Now

Track official adoption updates in target markets

While the UAE, Chile, and Vietnam are confirmed adopters, no public documentation specifies whether adoption applies to all new projects or only pilot initiatives. Enterprises should monitor national procurement portals and central bank or ministry of finance circulars for binding language—e.g., “shall reference” versus “may consider.”

Map product categories against documented city case attributes

The standard’s case-based structure means relevance depends on functional alignment. For example, if Shenzhen’s case emphasizes distributed energy management systems, exporters of related smart grid hardware should prioritize technical documentation harmonization—not broad ‘zero-carbon’ labeling. Focus should be on traceable linkages between product function and reported outcomes in the cited cases.

Distinguish between policy signal and procurement enforcement

ISO/TR documents are not mandatory standards; their use in procurement guidance reflects administrative preference—not legal obligation. Enterprises should verify whether referencing ISO/TR 37115—1:2026 triggers new testing, reporting, or data disclosure requirements—or merely serves as non-binding benchmarking material.

Prepare internal cross-functional alignment on terminology and metrics

Terms such as “carbon-neutral operation phase,” “embodied carbon ceiling for structural materials,” or “grid-responsive mobility integration” appear in the case studies. Companies should audit current technical datasheets, sustainability reports, and tender response templates for terminological consistency with these usage patterns—even where definitions remain non-normative.

Editorial Perspective / Industry Observation

From an industry perspective, ISO/TR 37115—1:2026 functions primarily as a coordination mechanism—not a compliance gate. Its value lies less in prescriptive thresholds and more in consolidating real-world implementation logic across diverse urban contexts. Analysis来看, its adoption by multiple countries signals growing institutional willingness to treat Chinese urban decarbonization experience as interoperable reference material—not just localized demonstration. Observation来看, this represents a shift from technology transfer to framework co-adaptation: foreign procurers are not adopting Chinese products wholesale, but rather adapting evaluation logic around Chinese-originated operational models. Current more appropriate interpretation is that this is an early-stage signal of standard-setting influence—not yet a driver of immediate export volume change.

This development does not replace existing IEC, EN, or ASTM requirements for product safety or performance. Rather, it adds a layer of contextual validation for how those products integrate into systemic urban decarbonization pathways. Industry actors should treat it as a strategic horizon marker—not an operational checklist.

Conclusion

ISO/TR 37115—1:2026 marks a milestone in the international recognition of Chinese urban sustainability practice—but its near-term impact remains procedural and contextual rather than regulatory or commercial. It does not mandate new certifications or override existing technical standards. Instead, it offers a structured vocabulary and evidence base that procurement authorities and project developers may increasingly use to assess coherence, scalability, and replicability of low-carbon infrastructure solutions. For industry stakeholders, the most rational stance is sustained monitoring—not urgent recalibration.
