China Regulators Launch Carbon Emissions Metrology Review of National ETS Emitters

This is a data-integrity move aimed at the measurement layer beneath China's national carbon market, not a change to trading rules or caps. It matters most to covered emitters, whose monitoring and reporting practices now face a joint review and baseline survey, and to anyone relying on ETS data for compliance or market analysis. The open question is whether this exercise tightens measurement standards in practice or remains a scoping effort; follow-up would show in how emitters' reported figures and verification requirements evolve.
