A shared climate, a shared future: Why China's green transition matters for the world

This summer, historic heatwaves swept across Western Europe. From Barcelona to Berlin, temperature records fell in a matter of days; wildfires spread across the Iberian Peninsula and southern France; and "tropical nights," when temperatures never dropped below 20°C, denied millions adequate relief overnight. Germany recorded temperatures above 41°C, while the United Kingdom issued Red Warnings for extreme heat on three consecutive days for the first time under its current warning system.

They are a warning from a changing climate that does not negotiate with borders, ideologies or levels of wealth. Reducing future emissions is important, but strengthening our capacity to withstand climate impacts already underway is equally urgent. That reality should shape how the world thinks about every credible contribution to mitigation, adaptation and resilience: not as a national possession, but as a shared global asset.

A recent multilingual CGTN online poll points in the same direction. Among 8,035 participants across five language platforms, 92.3% supported sharing climate technologies, disaster-prevention experience and early-warning resources; 88.7% backed climate-technology assistance to developing countries. The poll's message is a practical and clear one: no country can decarbonize or climate-proof the planet alone.

A transition measured in scale

China has developed one of the world's most comprehensive and operationally detailed national green-development strategies, designed not only to cut emissions directly but also to reshape the energy, industrial and ecological systems that determine long-term climate outcomes.

Its 15th Five-Year Plan, spanning 2026 to 2030, and Carbon Peaking Action Plan sit within one of the world's most detailed green-development frameworks, covering carbon governance, clean energy, industry, finance, ecological protection and international cooperation. The targets are concrete: by 2030, carbon dioxide emissions per unit of GDP are to fall 17% from 2025 levels; non-fossil energy is to reach 25% of total energy consumption; and installed wind and solar capacity is to reach at least 2,800 gigawatts.

That wind-and-solar target for 2030 is nearly 46% above the roughly 1,920 gigawatts installed by the end of May 2026. China also aims to double non-fossil energy supply by 2035 compared with 2025 and to raise non-fossil energy above 80% of total consumption by 2060. These goals matter not merely because they are large, but because they seek to weaken the historic link between economic growth and rising fossil-fuel use. Its action plan for carbon peak also calls for additional electricity demand increasingly to be met by additional clean-energy generation.

The importance of this scale extends beyond China. Domestic deployment becomes a global industrial force: it expands supply chains, accelerates technological learning and helps determine which low-carbon solutions become affordable elsewhere.

The strategy also moves beyond wind farms and solar panels. China is developing green hydrogen, ammonia and methanol production bases, along with storage, transport and pipeline infrastructure, to serve heavy industry, shipping and heavy-duty transport. It is also supporting carbon capture, utilization and storage for qualifying thermal-power facilities and carbon-intensive industrial processes. CCUS should not substitute for replacing fossil fuels where cleaner alternatives exist, but it can reduce emissions where substitution remains difficult.

China's green development agenda also looks beyond today's commercial technologies to possibilities at the frontier of energy innovation: controlled nuclear fusion, space-based power stations, high-temperature superconducting transmission and wireless power transfer. These are not yet commercial answers to the climate crisis. Fusion remains scientifically and economically unresolved; space-based solar power and superconducting grids face formidable engineering costs. But their inclusion in a national plan reveals a system thinking not only about the next five years, but about the energy architecture of the second half of the century. If even a fraction becomes viable, its global value will depend not only on who invents it, but on whether the technology can diffuse.

When domestic scale becomes a global asset

China's green transition is already helping make the global transition faster and cheaper than it would otherwise be. Its enormous domestic market, manufacturing capacity, integrated supply chains and intense industrial competition generate economies of scale that have lowered the cost of solar panels, batteries, electric vehicles and other clean technologies. For countries that cannot finance complete green industrial systems from scratch, access to affordable equipment is not merely a trade-policy question. It is a question of energy access, energy security and sustainable development.

Workers and communities tied to legacy sectors, in China and around the world, deserve a just transition that includes retraining, social protection and investment in human capital, enabling them to participate in the industries of the future. Supply chains also need diversification and resilience. But responding to those concerns by making clean technology substantially more expensive through protectionism can become self-defeating. Tariffs and fragmented standards may slow deployment in lower-income countries, where high financing costs already impede projects even when renewables are cheaper over their full lifetime.

Many climate-vulnerable countries contributed little to the accumulated emissions driving today's warming, yet face some of its harshest consequences. Affordable clean technology will not by itself solve their problems; finance, grids, institutions and skilled workers are also essential. But lower-cost solar panels, batteries and electric transport can help countries meet rising energy demand without reproducing every fossil-fuel-intensive stage of earlier industrialization.

Beyond mitigation

Lower-cost mitigation addresses only one half of the challenge. Even under optimistic emissions scenarios, serious climate impacts will persist, although their eventual severity still depends profoundly on how quickly emissions fall. Adaptation is therefore becoming central to national resilience and economic competitiveness. AI data centers and advanced manufacturing require large, reliable electricity supplies; hospitals need uninterrupted power. A grid vulnerable to heat, storms, floods or drought becomes a bottleneck for technological progress itself.

China's related plans combine stronger grids, pumped hydro and long-duration storage with AI-enhanced forecasting and early-warning systems. Sponge-city projects redesign urban landscapes to absorb and manage stormwater, while the South-to-North Water Diversion Project strengthens water security in the country's arid north. These measures were not all created solely as climate policies, but together they reinforce the physical foundations of an economy that can better confront environmental stress.

Physical resilience also requires institutional incentives. Governments are unlikely to protect ecosystems consistently if conventional accounting treats their destruction as growth and their preservation as economically invisible. China has therefore pioneered and progressively institutionalized Gross Ecosystem Product, or GEP, which measures services such as carbon sequestration, water purification and flood regulation. A national trial accounting specification was issued in 2022, and a growing number of localities use GEP in planning and performance evaluation. GEP does not replace GDP, and measurement alone cannot guarantee conservation. But what societies measure shapes what governments protect and invest in.

Competition without exclusion

Competition and cooperation need not be opposites. Nations will, and should, compete to lead in the green technologies that will power a clean energy future. But climate progress is not inherently zero-sum. Clean-energy deployment in one country can expand production, accelerate learning and lower costs for others.

The task is to draw a more intelligent boundary between strategic competition and shared necessity. Clean-energy supply chains should be made more resilient through diversification, greater capacity and interoperable standards, not by excluding major producers or denying countries affordable solutions. Mutual recognition of carbon-accounting and product-verification systems, collaborative research on storage and hydrogen, and lower friction for verified low-carbon goods could create a more integrated market that rewards decarbonization wherever it occurs.

Three principles follow. First, prioritize access over exclusion. Second, invest in adaptation with the same urgency as mitigation. Third, place the needs of the most vulnerable at the center of climate policy. The European heatwaves of 2026 will not be the last. In the face of shared but unequal risks, every credible contribution to mitigation and resilience, wherever it originates, should be treated more as an opportunity for practical cooperation rather than another arena for geopolitical division.

The world already possesses many of the technologies and much of the capital required. What it lacks is a system capable of directing them quickly and affordably to the places where they can make the greatest difference. Green innovation derives much of its value not from being hoarded, but from being deployed widely and rapidly.
