Beijing – September 24, 2026 -- Wind, solar, energy storage and electric vehicles are expanding rapidly worldwide, but grid integration limits, high financing costs and market-mechanism gaps are constraining the pace of the global carbon neutrality transition, according to the 2026 Global Carbon Neutrality Annual Progress Report launched at Tsinghua University on September 22.
Report tracks 198 countries and regions across 200 indicators
The report, presented by Tsinghua University professor Wang Can, draws on more than 200 indicators to assess progress toward carbon neutrality across 198 countries and regions, identifying the drivers and constraints shaping the transition. The launch coincided with the fifth anniversary of Tsinghua's Institute for Carbon Neutrality (ICON), the sixth anniversary of China's "dual carbon" goals, and the start of China's 15th Five-Year Plan period.
Mature clean technologies scale while system bottlenecks persist
The report finds a new phase of the low-carbon transition emerging, increasingly driven by technological progress but shaped by broader system conditions. Wind, solar, energy storage and electric vehicles continue rapid deployment as costs decline. Yet limited grid integration capacity, high financing costs, gaps in market mechanisms and barriers to international technology diffusion remain significant system-level bottlenecks.
Hydrogen and CCUS face commercialization hurdles
Emerging technologies including clean hydrogen and carbon capture, utilization and storage (CCUS) continue to encounter constraints tied to demand, infrastructure and viable business models, according to the report. Developing economies face particularly strong barriers, including high financing costs, trade barriers and insufficient system capacity to absorb and deploy green technologies.
Policymakers and UN officials weigh in at Tsinghua seminar
Speakers at the seminar included Li Gao, Vice Minister of China's Ministry of Ecology and Environment; Zhang Laibin, Chair of the Academic Committee of China University of Petroleum (Beijing); Zeng Rong, Executive Vice President of Tsinghua University; and Erik Solheim, former UN Under-Secretary-General and Executive Director of UNEP, who delivered remarks via video. The session was chaired by He Kebin, Member of the Chinese Academy of Engineering and Dean of the Tsinghua University Institute for Carbon Neutrality.
The findings indicate that while technological costs are falling and deployment is accelerating, the scale of the global transition increasingly depends on whether financing, infrastructure, markets and international cooperation can develop alongside technological progress.
