Earlier this year, the Chinese firm CATL, the world’s largest battery-maker, unveiled an electric-vehicle battery capable of delivering a remarkable 520 km of driving range after just five minutes of charging. The announcement came a month after BYD, China’s leading EV manufacturer, launched its own ultra-fast charging system. In solar, too, the numbers are staggering: Chinese firms can now produce over 1,200 GW of solar panels annually.

These feats are a product of the global green-tech race, which China leads by a wide margin. Some frame this as a problem of Chinese oversupply. But another way of looking at it is that the rest of the world is not deploying these technologies fast enough. While China’s green-manufacturing engine is running at high speed, others are idling.

Given this, Europe confronts a strategic choice. It can respond with defensive industrial policy: securing supply chains, raising tariffs, and futilely attempting to catch up. Or it can forge a shared competitiveness agenda, which will allow Brussels to use its strengths — rulemaking, coalition-building, and norm-setting — to shape the deployment environment, define standards, and guide green investment frameworks.

Despite the breakdown in ties between the EU and China in recent years, the idea of collaborating on clean trade and investment is not so far-fetched. The climate transition is the defining political and economic challenge of the 21st century. And on this front, the EU and China have become interdependent: If Europe pumps the brakes on decarbonization, Chinese assets could be stranded, whereas China could face retaliation if it refuses to collaborate or align with global norms. The question now is whether they can constructively shape their interdependence.

Taking advantage of the narrow window for establishing a climate partnership requires a deal that promotes each government’s core economic interests. For the EU, that means reducing reliance on Chinese imports while moving up the value chain. For China, it means maintaining access to a high-value export market amid a shifting global trade environment. Success requires pragmatism on both sides.

Europe confronts a strategic choice

Whether the EU and China can cooperate effectively depends on several factors. First, they must reach an agreement on local-content requirements. The EU should target domestic production of at least 40 percent of green technologies by 2030 — not just low-paid assembly, but higher-value activities such as research and development — to create jobs and build resilience.

Second, any partnership must open the door for joint ventures, which have helped China reach the technological frontier and are already emerging in the EU battery and automotive sectors. If correctly structured, such partnerships can drive mutual gains while building cooperation into long-term industrial strategies.

Third, trade measures must be carefully calibrated. While the EU has imposed tariffs as high as 45.3 percent on Chinese EVs, import barriers alone cannot close competitiveness gaps. At best, they can complement more strategic policy efforts such as local-content rules and industrial partnerships. If poorly implemented, they could further weaken Europe’s technological position, rather than buying it time to catch up with China.

Fourth, there is a need for structured mobility schemes. Some EU member states have begun restricting visas for Chinese engineers. This is short-sighted. Enabling European firms to host Chinese talent and vice versa would ensure that R&D and design, not just final assembly, occur in Europe.

Ultimately, finding a way to collaborate on decarbonization efforts would yield economic and geopolitical dividends for both sides. Collaboration with China would strengthen the EU’s resilience, bolster its industrial sector, and cement the bloc as a leader in clean tech. China would be able to offload surplus green goods; secure market access; and signal to the world that while the US is retreating from climate action, it remains dedicated to green growth.

The EU and China are more aligned than many realize. Both are net fossil-fuel importers. Both are major producers of zero-carbon technologies, and thus have an interest in sustaining global demand for green products. And, amid growing uncertainty, both have bet on the energy transition as the most viable path to competitiveness and innovation.

Both have wagered their future on green growth

This window of opportunity will not stay open forever. As scientific and political timelines converge, the coming months are critical to keep the world on track to meet the Paris climate agreement’s 1.5 C goal. The recent EU-China Summit laid the groundwork for closer cooperation on decarbonization. But, as pressure mounts to submit 2035 climate targets ahead of November’s UN Climate Change Conference in Belem, the next meeting of the Council of the EU in September, under the Danish presidency, will be pivotal.

With many European countries, most notably France, pushing for a clearer industrial and investment plan before committing to a strong 2035 emissions-reduction target, EU heads of state and government must devise a framework for transforming industry at the September meeting. An important part of that plan will be how the bloc engages with China.

By coalescing around the belief that the new must be built before the old can be phased out, Europe is starting to follow China’s strategy. But to do so, it must also learn from China’s coherent and systematic execution, which centers on long-term planning across the entire clean-tech value chain.

China, too, must step up with an ambitious 2035 emissions target that is aligned with its 2060 net-zero goal — meaning a roughly 30 percent reduction from peak emissions, which are expected to be reached this decade. This would bolster its international credibility and help create space for a strong EU target.

Both Europe and China have wagered their future on green growth. To make it a winning bet, and capture the full benefits of decarbonization, they must find common cause on clean trade and investment — one of the few areas where strategic self-interest and global public goods still converge.
