日本語

中国とドイツの低炭素鋼ラベルは技術的に類似し、深い脱炭素化と再生可能エネルギー利用のスクラップ生産を支援する。しかし、システム境界や排出会計方法に違いがあり、標準の整合性が貿易・投資シグナルを改善する可能性がある。地政学的不確実性が協力を阻むため、EUは国内生産の競争力強化が必要。

English

China and Germany's low-carbon steel labels are technically comparable, supporting deep decarbonization and renewable-powered scrap production. Differences in system boundaries and accounting methods remain; greater alignment could improve trade and investment signals. Geopolitical tensions pose challenges, so EU must bolster domestic competitiveness.

📄 Abstract（原文）

China and Germany have developed voluntary low-carbon steel labels that are already operational and used for certification in China and across Europe. The two label systems are broadly comparable in technical terms. Both support a transition towards deeply decarbonised primary steel and renewable-powered scrap-based production, though important differences remain in system boundaries and emissions-accounting methodologies. This technical comparability reflects the fact that steel decarbonisation is advancing in both China and Europe, with broadly similar technological pathways emerging. Greater alignment between the standards could facilitate trade, improve communication between market actors and give investors clearer signals about which decarbonisation routes are likely to remain credible and commercially viable across markets. International efforts to improve transparency and interoperability should therefore be supported. However, whether low-carbon steel labels can support international trade and cooperation will depend on wider geoeconomic and political conditions. Rising trade tensions, persistent EU concerns about Chinese overcapacity, and the prospect of faster low-carbon capacity expansion in China all pose challenges for European producers. Efforts to improve standards interoperability can help build common ground, but they must be accompanied by broader European policy measures to strengthen the competitiveness of domestic green steel production. Definitions of low-emission steel, including the new EU-level definition currently being developed, need to be ambitious and consistent in order to enable the emergence of lead markets. Currently, a new definition is being developed under the EU Ecodesign Regulation for application in public procurement and funding programmes across Europe in the context of the proposed Industrial Accelerator Act. Given the historic approach of Ecodesign regulation, it remains unclear how EU-level standards will relate to the existing voluntary labels in terms of methodology and ambition.
