Carbon Neutrality Enters a New Phase as Technology Advances
A new Tsinghua University report covering 198 countries and regions finds that renewable energy, storage and electric vehicles are accelerating the low-carbon transition, but financing, grid capacity, market mechanisms and technology access remain significant constraints.
BEIJING — The global transition towards carbon neutrality is entering a new phase in which technological progress is increasingly being matched by a more difficult question: whether countries have the financial, infrastructure and market systems needed to deploy those technologies at scale.
That is a central finding of the 2026 Global Carbon Neutrality Annual Progress Report, presented at a high-level seminar at Tsinghua University on September 22. The report assesses progress across 198 countries and regions using more than 200 indicators, examining both the forces accelerating the transition and the constraints slowing it down.
The report points to continued expansion of established low-carbon technologies, particularly wind and solar power, energy storage and electric vehicles. Falling technology costs and increasing deployment are helping to push the global energy transition into a phase where wider system conditions are becoming increasingly important.
But the researchers say technology alone will not determine how quickly countries can move towards carbon neutrality.
Limited electricity-grid capacity, high financing costs, gaps in market mechanisms and barriers to international technology diffusion are emerging as significant bottlenecks. For developing economies in particular, high borrowing costs and limited institutional and infrastructure capacity can make it harder to deploy green technologies even when those technologies are increasingly available.
The report also highlights challenges facing newer technologies.
Clean hydrogen and carbon capture, utilisation and storage, known as CCUS, continue to face questions over demand, infrastructure and commercially viable business models. While both are regarded as potentially important for sectors that are difficult to decarbonise, the report indicates that technological development must be accompanied by the market conditions required for commercial deployment.
The findings place greater emphasis on the systems surrounding the energy transition.
As renewable generation expands, electricity networks need greater capacity and flexibility. As electric vehicles become more widespread, charging infrastructure and power systems must expand alongside them. At the same time, investment frameworks need to make large-scale clean-energy projects financially viable.
The report also identifies international cooperation as an important factor in determining how quickly low-carbon technologies spread across borders.
Trade barriers can increase costs or restrict access to technologies, while differences in financing capacity and infrastructure can leave developing economies facing a more difficult path to adoption.
The findings were presented by Tsinghua University professor Wang Can during a seminar attended by representatives from government, academia and international organisations.
Speakers 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); Tsinghua University Executive Vice President Zeng Rong; and Erik Solheim, former United Nations Under-Secretary-General and Executive Director of the United Nations Environment Programme.
The seminar also marked the fifth anniversary of Tsinghua University's Institute for Carbon Neutrality and came as China entered the period covered by its 15th Five-Year Plan.
For Asia, the report's findings have particular relevance as governments attempt to balance decarbonisation with economic growth, energy security, industrial competitiveness and investment.
The assessment suggests that the next phase of the global carbon-neutrality transition will increasingly depend on whether countries can build the financial, infrastructure and market systems needed to turn technological progress into large-scale deployment.
The challenge, therefore, is no longer simply developing cleaner technologies. It is creating the conditions that allow those technologies to move from laboratories and individual projects into national energy systems and global markets.
