Hainan Province completed 2025 annual quota-surrender obligations with a 100% compliance rate under the expanded coverage of China’s national emissions trading scheme (ETS) — making it the first Chinese province to achieve that distinction. The achievement was disclosed at Hainan’s provincial showcase event for China’s 2026 National Low-Carbon Day, held on 15 June in Wanning City under the theme “Green Transition — Walking Together,” according to 碳排放交易网 (Tanpaifang), citing Hainan Daily.
Alongside the compliance milestone, officials said the province has been reinforcing three complementary climate-governance mechanisms: a dual carbon emission control system, a carbon footprint management framework, and a public carbon benefit mechanism. Zhang Jing, chief engineer of the Hainan Provincial Department of Ecology and Environment, framed the province’s trajectory as a green-transition model distinctive to its free-trade port status.
Additional progress cited at the event included: several Hainan clean-energy projects selected as exemplary cases for COP30; the province maintaining China’s highest new-energy vehicle penetration rate, with its fleet surpassing 500,000 units; and coordinated development of terrestrial forestry carbon sinks and marine blue carbon, leveraging the province’s tropical ecological endowment. The event was co-hosted by the Hainan Provincial Department of Ecology and Environment and Wanning City People’s Government.
Carbon Market Context
- Improved forest management (research): The research tracks 3,599 improved-forest-management projects, with roughly 22.6 million tCO₂e issued and 16.9 million tCO₂e retired — backdrop for the province’s parallel forestry carbon-sink development.
