The scale of China's clean technology dominance

China's industrial might has translated into an unparalleled command of the clean technology sector, making it an indispensable player in global decarbonisation efforts. This dominance is not merely about volume; it extends to the very structure of global supply chains and the setting of international standards.

Manufacturing leadership in key green technologies

China's production figures in critical clean energy sectors are staggering. The country produces approximately "80 per cent of the world’s solar panels"1, a cornerstone technology for renewable energy generation. Its influence is equally profound in the electric vehicle (EV) market, where it accounts for "70 per cent of EVs" and "more than 90 per cent of heavy electric trucks". Furthermore, China produces "80 per cent of lithium-ion battery cells", essential for both EVs and grid-scale energy storage. Between 2019 and 2025, Chinese companies accounted for "55 per cent of the world’s total US$1.1 trillion in clean energy manufacturing investment". These figures underscore a deep global reliance on Chinese-made components for the energy transition.

Global supply chain centrality

The sheer scale of China's manufacturing means that global clean energy supply chains are deeply intertwined with its industrial base. This centrality creates a significant dependency for countries worldwide, including the UK, aiming to meet their net-zero targets. As authors Peter Newman and Ray Wills state, "The world is already deeply, irreversibly dependent on Chinese clean technology for the net zero transition". This reliance affects everything from the cost and availability of renewable energy projects to the pace of EV adoption. In March 2026 alone, China’s exports of solar, batteries, and EVs reached a record US$26 billion, marking a 70 per cent increase on the same month the previous year.

Shaping international technology standards

Beyond manufacturing, China is increasingly asserting its influence in setting global technology standards within the clean energy sector. Historically, the country adopted international standards; however, its role has shifted to actively shaping them. The Clingendael Institute notes that "China’s role in global standard-setting has shifted... from adopting international standards to actively shaping them". This means that the technical specifications, interoperability, and performance benchmarks for future green technologies are increasingly being influenced by Chinese innovation and industrial priorities. For the UK, engaging with these evolving standards is vital to ensure compatibility and competitiveness in the global market. For example, in January 2026, China introduced the world’s first mandatory energy consumption standard for battery-electric passenger vehicles, and in July 2026, its mandatory battery safety standard took effect, requiring no fire or explosion from EV power batteries.

Drivers behind China's green technology leadership

China's ascent to clean technology dominance is not accidental; it is the result of a concerted, multi-faceted strategy combining industrial policy, economic incentives, and a strong focus on innovation.

Strategic industrial policy and sustained investment

A key driver has been China's long-term strategic industrial policy, which has prioritised clean energy as a pillar of economic growth and national security. This has involved massive state-backed investment in research, development, and manufacturing capacity across the clean technology spectrum. This sustained commitment has allowed Chinese firms to build vast production capabilities and achieve economies of scale.

Economic opportunism and market scale

China's immense domestic market has provided a fertile ground for clean technology companies to test, refine, and scale their products. The sheer volume of demand for solar, wind, and EVs within China itself has allowed manufacturers to drive down costs and perfect production processes. This domestic market scale, combined with a pragmatic approach to economic opportunism, has enabled Chinese firms to become globally competitive, often at lower price points than their international counterparts.

Innovation and research & development

While often perceived primarily as a manufacturing hub, China has also significantly ramped up its investment in clean energy innovation and research & development (R&D). This focus on innovation has allowed Chinese companies to move beyond simply producing components to developing proprietary technologies and intellectual property, further solidifying their leadership in the sector. In 2025 alone, China took the lead in formulating 285 international standards under the ISO and IEC, an increase of 27 per cent year on year, in areas including new energy, electric vehicles, and lithium-ion batteries. It also signed 130 standardisation cooperation agreements with 75 countries and organisations.

Global and UK implications for the net zero transition

China's clean technology dominance presents a complex set of implications for the global net-zero transition, with particular challenges and opportunities for the UK.

Dependency and energy security concerns

The profound reliance on Chinese clean technology raises significant questions about energy security for the UK. An over-concentration of supply chains in one country can expose nations to geopolitical risks, trade disruptions, and potential price volatility. For the UK, ensuring a stable and affordable supply of clean energy components is paramount for meeting its ambitious net-zero targets and maintaining national energy independence. This dependency necessitates a careful balancing act between global engagement and domestic resilience.

Impact on decarbonisation efforts and costs

China's ability to produce clean technologies at scale and at competitive prices has undeniably accelerated global decarbonisation efforts. Without China's manufacturing capacity, the cost of solar panels, batteries, and EVs would likely be significantly higher, slowing down the transition away from fossil fuels. However, this cost advantage also means that protectionist measures, such as the 25 to 100 per cent tariffs imposed by the US and EU on Chinese EVs and clean technology, could inadvertently raise the cost of clean energy deployment in the UK, potentially hindering its own net-zero progress.

Competitive landscape for UK industry

For UK industry, China's dominance creates a challenging competitive landscape. Domestic clean technology manufacturers face intense price competition, making it difficult to scale and innovate. However, it also presents opportunities for collaboration, niche specialisation, and the development of advanced components or services that complement China's mass production capabilities. The UK must identify strategic areas where it can build competitive advantage and foster a thriving domestic clean tech ecosystem.

Strategic responses for the UK: beyond dependency

Navigating China's clean technology dominance requires a nuanced, proactive, and multi-pronged strategy for the UK. It must move beyond simply acknowledging dependency to actively shaping its own clean energy future.

Fostering domestic clean technology innovation

The UK must significantly increase investment in domestic clean technology innovation, research, and manufacturing. This includes targeted funding for R&D in areas like advanced battery chemistries, next-generation solar, green hydrogen, and sustainable materials. Policies should incentivise the scaling up of UK-based production, creating a robust ecosystem that supports start-ups and established firms alike. Building a strong domestic foundation reduces reliance on external supply chains and creates high-value jobs.

Building resilient green tech supply chains

Diversifying and strengthening green technology supply chains is critical. This involves exploring alternative sourcing options, encouraging near-shoring or friend-shoring where feasible, and investing in critical raw material processing and recycling capabilities within the UK. Developing strategic reserves of key components and materials could also mitigate risks associated with supply disruptions. The goal is not to decouple entirely, but to build resilience and reduce single-point vulnerabilities.

Engaging in international cooperation and standard-setting

Rather than isolation, the UK should pursue strategic international cooperation with China and other global partners. This includes active engagement in international forums that shape technology standards, ensuring UK interests and innovations are represented. Building reciprocal data transparency and fostering two-way trade and investment flows can help manage dependencies effectively, promoting a more equitable and affordable global decarbonisation effort.

Policy levers and investment strategies

Policymakers and investors in the UK have several levers at their disposal. This includes implementing clear, long-term industrial strategies for clean tech, offering targeted grants and tax incentives for domestic manufacturing, and streamlining planning and permitting processes for renewable energy projects. Public-private partnerships can de-risk investments in nascent technologies, while green finance initiatives can channel capital towards building a resilient, abundant clean energy future.

Forging an abundant clean energy future for the UK

The ultimate goal for the UK is to move beyond dependency and forge its own abundant clean energy future, characterised by resilience, innovation, and strategic global engagement.

The role of vertical integration in national resilience

Achieving national resilience in clean energy deployment can draw inspiration from models that vertically integrate and rebuild energy systems from scratch. By owning and optimising every stage of the energy value chain - from generation to distribution and consumption - the UK can gain greater control over costs, accelerate deployment, and enhance security. This approach, which prioritises delivering the cheapest, cleanest energy possible, can serve as a powerful framework for building a robust domestic clean tech industry and ensuring a reliable energy supply for all.

Accelerating UK's own clean energy deployment

The UK has significant potential to accelerate its own clean energy deployment. This involves not only investing in large-scale renewable projects but also empowering communities and businesses to generate and manage their own energy. Policies that support distributed generation, smart grid technologies, and energy storage solutions can create a more decentralised and resilient energy system. Speeding up the transition means cutting through bureaucratic hurdles and fostering an environment where clean energy projects can flourish.

Balancing global engagement with domestic strength

Ultimately, the UK's strategy must balance pragmatic global engagement with a relentless focus on domestic strength. This means acknowledging China's indispensable role in the global clean energy transition while simultaneously building robust UK capabilities. By fostering innovation, diversifying supply chains, and strategically cooperating on international standards, the UK can secure its net-zero ambitions, create economic opportunities, and ensure it has the "power to play with" in its own clean energy future.
