China’s carbon market trial by fire: Early enforcement data reveals compliance and economic trade-offs

Chinese scientists and policy analysts have delivered the first rigorous empirical assessment of enforcement within China’s national emissions trading scheme (ETS) following its inaugural compliance period. The study, set to appear in Energy Policy (Volume 217, October 2026), blends legal and economic analysis to ask a fundamental question: does enforcement produce actual emissions abatement, or merely a reshuffling of compliance costs?

The research, co-authored by Ying Xie, Michael Faure, and Aylin Aydin Cakir, draws on empirical evidence from firm-level compliance behaviour. Their findings shed light on how market participants reacted to penalties, monitoring, and verification protocols during a period that tested the scheme’s institutional backbone. The analysis reveals that enforcement intensity matters greatly: weak oversight leads to strategic under-reporting and late compliance, while stringent enforcement drives genuine reductions but may impose disproportionate costs on smaller, less flexible emitters.

For China, the stakes are enormous. The national ETS covers roughly 5 billion tonnes of CO₂ annually, dwarfing all other carbon markets combined. How Chinese regulators calibrate enforcement — whether they lean toward market-friendly flexibility or rigid command-and-control — will influence not only domestic decarbonisation trajectories but also the confidence of international partners and investors tracking China’s climate governance credentials. This research offers one of the first evidence-based roadmaps for that calibration.

Why it matters: China’s ETS is a laboratory for the world. The enforcement lessons from its first compliance period will inform how emerging carbon markets in Asia and beyond design rules that are both credible and economically sustainable.
