Contexto
What changed: Adoption of stricter motor vehicle exhaust limits under the CHINA-VI standard in 18 pilot cities in July 2019, one year before nationwide rollout. Comparison: 258 non-pilot prefecture-level cities that adopted the standard later, evaluated before and after July 2019. Limits: The short monthly panel through 2020 cannot observe long-term fleet turnover or capture secondary emissions from increased electric vehicle electricity demand.
