Gasgoo Munich-XPENG recently signed carbon credit trading agreements with Porsche and other international automakers. These cover regulations in the EU, UK, and Australia. The total deal value exceeds 1 billion yuan. XPENG is poised to generate over 500 million yuan from these credits in 2026 alone.The significance of this partnership extends far beyond immediate financial gain. It marks a fundamental shift for Chinese automakers expanding globally. They are moving from merely adapting to overseas rules to actively helping international peers achieve compliance. They achieve this by leveraging pure-electric sales and carbon management capabilities. Carbon credit trading is emerging as a new synergy between Chinese and foreign automakers.Fines Drive Urgent Compliance NeedsThe fundamental driver behind carbon credit trading is the continuous tightening of emission regulations. Major global auto markets are also strictly enforcing penalty mechanisms.The impending EU fines are the primary catalyst. Under new regulations effective in 2025, fleet average CO2 emissions for passenger cars must fall to 93.6 grams per kilometer. The penalty is 95 euros for every gram exceeded per vehicle. Industry estimates put potential sector fines as high as 15 billion euros. That figure is enough to force any traditional automaker to reassess its compliance strategy.Consider Volkswagen Group: its fleet average CO2 emissions for 2025 stand at 100 grams per kilometer—above the EU’s 93.6-gram target. CFO Arno Antlitz said in May that missing emission targets from 2025 to 2027 could result in cumulative fines of 1.5 billion euros. Annual penalties are estimated at 400 million to 500 million euros.Image Source: PorschePorsche's situation is illustrative. The brand is currently refocusing on internal combustion engine vehicles just as its EV sales slump. By the end of June, sales of the Taycan had fallen roughly 20% year-on-year, while the electric Macan dropped about 30% in Europe. Only the new electric Cayenne saw growth, though volumes remain modest. Dataforce data shows Porsche's fleet average CO2 emissions reached 130.2 grams per kilometer through June this year. This is up 9.8% from 118.5 grams in the same period of 2025. Facing the dual pressures of impending fines and a slowing EV transition, Porsche opted to exit Volkswagen Group's internal emissions pool. It formed an open compliance alliance with XPENG. Essentially, the move seeks a compliance path with lower costs and higher certainty.XPENG's carbon credit cooperation spans multiple regulatory frameworks, including the EU, UK, and Australia. This demonstrates that carbon credit trading is not isolated. It is a systemic market expanding globally in sync. EU regulations allow automakers to form open emissions pools, calculating averages based on their new fleets. High-emission internal combustion and performance brands can leverage surplus credits from pure-electric makers to offset excess emissions and avoid penalties. In March 2025, the EU agreed to assess compliance based on a three-year average from 2025 to 2027, but the targets themselves were not lowered. That means fines are merely deferred, not canceled. This makes the firm demand for carbon credits more pressing as the timeline clarifies.Why XPENG?The essence of carbon credit trading is the monetization of technological advantages into carbon assets: the more pure-electric vehicles a company sells, the more credits it accumulates. XPENG's ability to supply in this arena stems directly from the rapid growth of its overseas sales and the premium shift in its product mix.Data shows that in the second quarter of 2026, XPENG's overseas sales surpassed 20,000 units for the first time—an 81% year-on-year jump. In the first half of this year, overseas revenue accounted for over 25% of the total, with an average selling price exceeding 40,000 euros. Both per-vehicle revenue and gross profit lead among Chinese automakers expanding abroad. From January to July 2026, XPENG ranked first in sales among Chinese new-energy pure-electric brands in countries like Norway, Denmark, France, and Portugal. This demonstrates that XPENG's carbon credit supply relies not on sporadic volume in a single market, but on sustained sales across multiple high-value European markets. The stability and predictability of its credits are significantly superior to those of competitors chasing short-term volume spikes.Image Source: XPENGPorsche's choice of counterparty is particularly notable. As one of Volkswagen Group's most profitable brands, Porsche's decision to exit the group's internal emissions pool is significant. It independently formed an alliance with XPENG, suggesting XPENG's offer provides superior cost efficiency and compliance certainty compared to internal allocation. The Porsche-XPENG pool will be managed by Porsche and cover both 2026 and 2027. It is an open pool, meaning other brands or automakers can join.Other open pools include one managed by Tesla with Ford, Honda, Mazda, and Suzuki. Another is managed by Mercedes-Benz, comprising Volvo, Polestar, and Smart. XPENG's ability to secure Porsche as a partner demonstrates the recognition its carbon credit supply capability has received from mainstream international automakers.A vice president at XPENG noted that international automakers' choice to partner with XPENG is proof of the company's rising global influence. XPENG has signed multiple strategic cooperation agreements with Volkswagen Group in the past. This track record of successful collaboration has enabled XPENG to partner with more international OEMs.In fact, Chinese automakers have precedents in carbon credit trading. Leapmotor transferred EU carbon credits to Stellantis in 2025, generating 1.11 billion yuan in related revenue for the year. The cap for its 2026 credit trading has been significantly raised to 2.8 billion yuan.Analysts point out that carbon credit revenue is not a one-off gain divorced from main operations. It is an added value derived from expanding overseas sales and pure-electric product portfolios. As models like the MONA L03 and XPENG G9L enter international markets, XPENG's tradable carbon credits continue to accumulate, leaving room for further revenue growth.The Shift in Sino-Foreign Automaker CollaborationThis carbon credit cooperation spans regulatory systems in the EU, UK, and Australia. The industry views it as a case study of the shift from simple product exports to comprehensive exports of products, compliance, and carbon management capabilities. As one industry view holds, "The next stage of going global isn't just about product competitiveness—it’s about understanding global rules."XPENG's collaboration with international automakers did not begin with this round of carbon credit trading. Since 2023, XPENG and Volkswagen Group have deepened their cooperation across models, platforms, electrical and electronic (E/E) architecture, and charging networks. In 2023, Volkswagen Group acquired a 4.99% stake in XPENG for approximately $700 million to access its software architecture and AI capabilities. In February 2024, the two signed a joint development agreement for platform and software technology. This was followed in April 2024 by an E/E architecture strategic cooperation framework. In January 2025, they began building China's largest super-fast charging network. By March 2026, the first jointly developed model rolled off the production line and opened for pre-orders. It is a full-size pure-electric SUV named "Yuzhong 08," equipped with XPENG's latest VLA intelligent driver assistance system.This trajectory reveals a key trend: the relationship between Chinese and foreign automakers is shifting. It is moving from the old "market for technology" paradigm to a new "technology + carbon management" two-way output paradigm. Volkswagen needs XPENG's electrification platforms and intelligent technology to accelerate its transition, as well as XPENG's pure-electric sales to optimize its carbon credit accounting. XPENG, in turn, needs Volkswagen's global manufacturing system and brand channels to accelerate its overseas expansion, while also using technical services and carbon trading to diversify its revenue structure. Carbon credit trading represents the most innovative link in this new synergy. It converts the first-mover advantage of Chinese automakers in electrification into quantifiable, tradable carbon assets recognized by the international market.Porsche's exit from the Volkswagen Group emissions pool may actually lower the group's overall carbon emissions level. Porsche's high-emission vehicles will no longer be factored into Volkswagen's calculations. This strategic adjustment of "governing through separate pools" illustrates that carbon compliance is evolving from internal group coordination toward a flexible, market-based allocation across enterprises and brands.Diversified Revenue Structure and Long-Term Industry ChallengesWhile carbon credit trading revenue attracts attention, it represents just one component in XPENG's diversified revenue structure. It also provides a snapshot of the upgraded narrative of Chinese automakers expanding globally.Image Source: XPENGBeyond vehicle sales, XPENG is establishing a revenue architecture built on a foundation of complete vehicles, powered by technical services, supplemented by carbon credits, and looking ahead to physical AI. The growth of technical service revenue is striking. In the second quarter of 2026, service and other revenue accounted for only 13.7% of total revenue. However, it contributed 49.6% of gross profit. This income stems primarily from R&D services provided to Volkswagen Group, with a gross margin of 75.1%. The underlying logic of technical services and carbon credit trading is similar. Neither relies on the linear growth of vehicle deliveries. Instead, they "package and sell" the capabilities accumulated in electrification and intelligence. This model allows XPENG to support overall profitability through high-margin non-vehicle businesses even while facing pressure on vehicle gross margins.Yet it must be clearly recognized that carbon credit income is policy-dependent and difficult to use as a long-term anchor for valuation. In March 2026, the EU changed its assessment method to a three-year average for 2025 to 2027. If targets are further relaxed or carbon pricing mechanisms adjusted in the future, the scarcity and trading value of carbon quotas could shrink. While carbon trading brings substantial extra income, the industry's structural shortcomings are evident beneath the high transaction volumes. One-off credit gains cannot cover the investment required for low-carbon transformation across the entire supply chain. Furthermore, fragmented global carbon accounting standards continue to raise compliance costs for global expansion. Ding Shanshan, Green Supply Chain Project Director at the Institute of Public and Environmental Affairs (IPE), noted the stringent international green trade rules. She urged Chinese automakers to seize this opportunity to accelerate transparent disclosure of product carbon footprints. This would force deep decarbonization across the supply chain.Meanwhile, the EU's Carbon Border Adjustment Mechanism (CBAM) is gradually moving from formal implementation toward institutional maturity. Although CBAM currently covers basic industrial goods like steel, aluminum, cement, and electricity, the automotive supply chain is highly intertwined with these sectors. Steel is the foundational material for car bodies and structural components, while aluminum is widely used in lightweighting and battery casing manufacturing. This means the impact of CBAM on the auto industry is essentially a systemic cost restructuring transmitted from the material end to the vehicle end.Thus, the future competition among automotive enterprises will no longer be merely about cost control capabilities, but about supply chain data governance capabilities. Pioneers in carbon credit trading already possess a first-mover advantage in carbon data management and supply chain carbon footprint tracking. The transferable value of this capability will far outstrip the revenue scale of the carbon credit trading itself.
