汽车产品碳足迹报告（二）：尽管有气候承诺，排放量仍在上升？梅赛德斯-奔驰对供应链问题保持沉默

In 2025, the Institute of Public and Environmental Affairs (IPE) andGreen Jiangnan, together with nine other environmental organizations,jointly launched the “Vehicle Carbon Footprint Snap” campaign.The To accelerate low-carbon transformation of China’s automotive sectorand provide consumers with more environmentally sustainable choices,the eleven environmental organizations collectively sent an open letter Big Data and AI Enable the Development of an Theglobal automotive industry continues to thrive,deliveringsignificantmobility benefits while generating substantial carbonemissions. Although the rise of new energy vehicles—particularly Research by the China Automotive Data Co., Ltd.1indicates that, for passenger vehicles, carbon emissions from the raw material acquisitionstage, primarily driven by steel and aluminum production, are 10 to 15 Encouragingly, many steel and aluminum producers have alreadydeveloped low-carbon product offerings. However, limited demandfrom automakers has constrained large-scale adoption, preventing To addressthese obstacles, under the guidance of the ChinaForum ofEnvironment Journalists, Blue Map and theChina Products CarbonFootprint Factors Database(CPCD) jointly developed the“ProductCarbon Scan”tool. Leveraging data from platforms such asChina Based on this tool, IPE and Green Jiangnan(PECC), together withShandong Environmental Protection Foundation, Green Qilu, Airman,Green Anhui, Green Taihang, Wuhu Ecology Center, BAYU Public welfareinitiative"Environmental Protection at Our Fingertips".Launched jointly byChina Forum of Environment Journalistsand IPE in2018, this initiative closely aligns with the theme "Beautiful ChinaStarts As of15October 2025, over 110,000snapshotshave beentakenin 131cities.These data present a distinctive “Street Snap Automotive CarbonFootprint” landscape. To quantify the aggregate climate impact of theobserved vehicle samples across their full life cycles, we calculated the The Heatmap shows that Volkswagen, Toyota, Mercedes-Benz, Audi,and BMW rank among the top five brands in terms of carbon reductionpotential. Volkswagen exhibits the highest street snap frequency,reflecting its extensive on-road presence, while Mercedes-Benz recordsthe highest average carbon footprint among the captured models. In Why Mercedes-BenzRanked High? Netizen street snaps show that Mercedes-Benz ranks 2ndinthe"Street Snap Carbon Reduction Potential". Calculated based on driving An analysis of the factors underlying Mercedes-Benz’s elevated carbonfootprint intensity indicates two primary drivers. First, the branddemonstrates a relatively high street snap frequency, reflecting strong Second,the average carbon footprint of the Mercedes-Benz modelscaptured in the campaign is 297.09 g/km3, exceeding that of 86% of thebrands in the observation sample. Specifically: •As sales cornerstones, the C-Class, E-Class, and GLC-Classmodels(medium or large gasoline sedans and SUVs)exhibit •Medium-large/large gasoline SUVs and MPVs modelssuch asthe G-Class, GLS, V-Class, and GLE, although having a lowerstreet snap frequency, have average carbon footprints between •Although the EQ series electric SUVs have low emissions duringtheusephase, the full life cycle carbon footprints of these Admittedly, the market positioning of different automakers varies. As aflagship brand in the high-end market, Mercedes-Benz products satisfythe needs of specific users. However,in the faceof the severe climate TheMercedes-Benz Companyisalso aware of this issue. In its 2024Annual Report and website, Mercedes-Benz reiterated its Ambition2039:“Create a net carbon-neutral Mercedes-Benz new vehicle fleet vehicle fleet up to 50% across all stages of the value chain over theentire lifecycle within the next decade”. Mercedes-Benz also recognizes that upstream raw materials likebatteries, steel, and aluminum, are emission hotspots.The company Inits2024 Annual Report, Mercedes-Benz made more commitmentsregardingthe procurement of low-carbon steel and aluminum, including:“purchase200,000 tons ofCO2-reducedsteel annuallyfromsuppliersfor its own press plants this decade”,andintegratealuminum onwards is to be produced using renewable energies”.According toMercedes-Benz,“this can lead to a CO2reduction of up to 50% compared to conventionally produced aluminum used in Europe”. However, data publicly disclosed by Mercedes-Benz in its annual reports45shows that the company's Scope 1, 2and3 emissions, anera slight decline in 2023, rebounded in 2024. Emissions from Purchased In accordancewith its market positioning,we thinkMercedes-Benzmust implement the procurement of low-carbon steel and aluminum The360° ENVIRONMENTAL CHECK MERCEDES-BENZ CLA WITH EQTECHNOLOGYreleased by Mercedes-Benz in 2024 shows:“around40% plantsusingrenewable energy”. Taking the CLA 250+ model as anexample,thissavesa total of around0.4metrictonsof CO2emissions. In addition,“around 39 kg of steel from electric arc furnaces, which
