Amid the global wave of carbon neutrality, the European Union officially rolled out the New Battery Regulation in 2023, establishing a green barrier for the battery industry with carbon footprint as its core focus. The regulation mandates that, starting from 2025, all electric vehicle batteries, industrial batteries with a capacity exceeding 2 kWh, and light means of transport batteries entering the EU market must provide carbon footprint declarations, with a phased implementation of carbon footprint grading management and threshold-based access. This move not only reshapes the competitive landscape of the global battery industry but also elevates the carbon footprint to a "make-or-break" threshold for battery enterprises seeking to establish a foothold in the EU market.
I. Carbon Footprint: The Core Lever of the EU's Green Barrier
The EU's New Battery Regulation transforms the carbon footprint into a mandatory compliance threshold for battery enterprises through three key mechanisms: carbon footprint declaration, grading management, and threshold-based access. The regulation explicitly requires enterprises to calculate the carbon footprint of batteries using the Life Cycle Assessment (LCA) method, covering four stages: raw material acquisition, production and manufacturing, transportation and distribution, and recycling. The data must be precise to the amount of carbon dioxide equivalent (kgCO₂e/kWh) per kilowatt-hour of battery energy. For instance, Chinese leading enterprises like CATL must complete carbon footprint declarations for their battery products in the European market by August 2025; otherwise, they will face a sales ban.
Carbon footprint grading management categorizes battery products into different environmental grades by establishing performance grades and maximum thresholds. Starting from 2026, batteries in the EU market must be labeled with carbon footprint grades, and consumers can access full lifecycle carbon emission data of batteries through QR codes. If a battery's carbon footprint value exceeds the threshold specified in the delegated acts after July 2027, it will be directly prohibited from entering the EU market. This "carbon label" system not only influences consumer choices but also forces enterprises to accelerate technological upgrades.
II. The "Carbon Threshold" Dilemma for Chinese Battery Enterprises
As the world's largest battery producer, China faces multiple challenges under the EU's carbon footprint regulations. First, differences in power structures lead to disadvantages in carbon footprint accounting. China's thermal power accounts for 66.3%, while the EU's average power carbon footprint is more than 20% lower than China's. Even if enterprises adopt distributed photovoltaic power generation, they still face the issue of the EU's non-recognition of China's green electricity certificate system. For example, a leading Chinese enterprise's battery carbon footprint may be 15%-20% higher than that of its Japanese and Korean competitors under EU rules, directly weakening its price competitiveness.
Second, discrepancies in accounting rules exacerbate compliance difficulties. The EU's new regulations exclude two carbon footprint calculation models: "supplier electricity products" and "residual electricity consumption portfolio," retaining only the "national average electricity consumption portfolio" and "direct connection electricity" approaches. This means that Chinese enterprises cannot reduce their carbon footprints by purchasing green electricity, and the direct connection electricity model poses stringent requirements for grid access that most domestic enterprises struggle to meet. In addition, the EU's expanded scope for calculating transportation carbon emissions to cover the entire chain from "battery manufacturing plants to the EU market" further increases the carbon footprint value of Chinese batteries.
Finally, the lack of data traceability and certification systems poses hidden barriers. The EU requires enterprises to provide data on all lifecycle activities of batteries, including raw material lists, energy consumption, and transportation distances, which must be verified by notified bodies. However, China's battery industry chain has fragmented data and inconsistent standards, making it difficult for enterprises to establish a complete carbon footprint database within a short time. For example, an enterprise had its carbon footprint declaration rejected by the EU due to its inability to provide carbon emission data for the cathode material production process of its batteries.
III. Technological Breakthroughs and Industrial Restructuring: Enterprises' Path to Breakthrough
Facing the EU's carbon footprint "make-or-break" threshold, Chinese battery enterprises are reshaping their competitiveness through technological innovations and industrial restructuring. In terms of zero-carbon factory construction, enterprises like CATL and Envision AESC have established zero-carbon industrial parks in Yibin, Ordos, and other locations, reducing carbon emissions in the production process through photovoltaic power generation and direct green electricity supply. For instance, Envision AESC's Ordos factory has reduced the carbon footprint of battery production by 40% through 100% green electricity supply, reaching advanced EU levels.
The application of recycled materials has become another key breakthrough. The EU's new regulations require that, after 2027, the content of recycled cobalt, lithium, and nickel in power batteries must not be less than 16%, 6%, and 6%, respectively, forcing enterprises to accelerate their布局 (lay out) in the battery recycling industry. Enterprises like GEM have achieved metal recovery rates of over 98% from spent batteries through hydrometallurgical technology and developed low-carbon recycled materials. For example, batteries produced using recycled cobalt can reduce their carbon footprint by 30% compared to those using primary materials, helping enterprises meet the EU's carbon footprint thresholds.
Global capacity deployment provides enterprises with a "detour" solution. Enterprises like CATL and EVE Energy have built battery factories in Germany, Hungary, and other locations, leveraging local green electricity resources to reduce carbon footprints. For instance, CATL's German factory has reduced the carbon footprint of battery production by 25% compared to domestic factories by connecting to Nordic hydropower. Meanwhile, these factories can serve European automakers nearby, reducing transportation carbon emissions and further enhancing product competitiveness.
IV. Policy Synergy and Standard Alignment: Building Long-Term Competitiveness
To overcome the EU's carbon footprint dilemma, synergistic efforts are needed in policy, standards, and technology. At the national level, it is essential to accelerate the establishment of a regular release mechanism for power carbon footprint factors and promote the alignment of power carbon footprint accounting with international standards. For example, the Ministry of Ecology and Environment has initiated research on power carbon footprint factors and could draw on EU experience to establish a full lifecycle power carbon footprint database covering power generation, transmission and distribution, and fuel transportation in the future.
In terms of industry standard setting, it is necessary to promote the mutual recognition of international standards for battery carbon footprint accounting methods, data collection specifications, and certification systems. The China Automotive Technology & Research Center has taken the lead in formulating the Guidelines for Carbon Footprint Accounting of Power Batteries and could collaborate with institutions like the German Institute for Standardization (DIN) in the future to align the GBA battery passport rules with EU standards. For example, by establishing a unified battery carbon footprint data platform, mutual recognition of carbon footprint data for Chinese and EU battery products can be achieved.
In technological innovation, it is crucial to increase R&D investment in next-generation low-energy-consumption battery technologies such as solid-state batteries and lithium-sulfur batteries. For instance, solid-state batteries can increase energy density by more than 50% compared to traditional lithium-ion batteries and reduce carbon emissions in the production process by 30%. At the same time, the application of technologies like blockchain and the Internet of Things in battery carbon footprint tracking should be explored to enhance data transparency and credibility.
Conclusion: From "Make-or-Break" Threshold to "Competitive Moat"
The EU's new battery carbon footprint regulations pose both challenges and opportunities. For Chinese battery enterprises, crossing this "make-or-break" threshold is a process that drives the green transformation of the industry and builds global competitiveness. Through measures such as zero-carbon factory construction, recycled material application, and global capacity deployment, enterprises can transform carbon footprints from compliance burdens into technological barriers. Deepened policy synergy and standard alignment will further assist China's battery industry in evolving from a "follower" to a "leader" in the global carbon neutrality journey. When the carbon footprint is no longer a "make-or-break" threshold but becomes an enterprise's competitive moat, China's battery industry's green competitiveness will truly shine in the global market.
