CPCD访谈 | 街拍11万辆车，解锁412万吨碳足迹：奔驰被点名保持沉默，为什么碳足迹不降反增？

Street SnapPhotos of 110,000VehiclesReveal4.12 Million Tons ofCarbon Footprints: Mercedes-Benz "Named andShamed",Remains Silent.Why DidItsCarbon Footprints Increase Instead ofDecrease? Author:CPCD CommunityPlanning:Ning Zhiyuan (NSF International)Experts:Ma Jun (Institute of Public & Environmental Affairs,IPE), Ning LizheManaging Editor:Ning Zhiyuan (NSF International)Text Review:Zhou Quan (Intertek Testing Services (Shanghai) Ltd.), Sun Xinzheng (FangyuanTesting and Certification Group)Commentary:Lao C Questions The "Vehicle Carbon Footprint Snap" campaignhassparkedquestioning: Why is the carbonfootprint of Mercedes-Benz cars consistently high? Whichsector of productionhas a greaterimpact on a vehicle's carbon footprint? Why do cars that look extremely similar have suchvastly different carbon footprints in different market contexts? What is the currentsituationand what are the problems regarding carbon footprint management in Chinese automotiveenterprises? How should work proceed in the future? To address these questions, CPCD invitedspecial guestsMa Jun, Director of the Institute ofPublic & Environmental Affairs (IPE) andNing Lizhe,automotive industry practitioner for aninterview. Answers 1. CPCD: You cannowcheck carbon footprints just by snapping a photo? How is AIreshaping greenconsumerrighttoknow?The Blue Map (Wei Lan Di Tu)published thearticle"Automotive Product Carbon Footprint Report (II): Emissions Rise Despite ClimatePledges? Mercedes-Benz Remains Silent on Supply Chain Concerns."The "Product CarbonScan" function in the Blue Map App can quicklyidentifya product's carbon footprint bytaking a photo with a mobile phone. Approximately how many automotive products havebeen photographed? What is the basic principle of "Product Carbon Scan"? Ma Jun:In 2023, we started the AutomotiveSteel&Aluminum Collaborative EmissionReduction Project.Ourreason for launching this project is that, globally, to advance climateaction,wemustaccelerate the decarbonization of upstream high-emissionsindustries.Among thedifficult-to-abatesectors, steel and aluminum smelting are verysignificant, andthe automotive industry ranks in the top three for steel and aluminum usage. Although the real estate industry uses more volumeof steel and aluminum, the consumptionin that sector has been declining in recent years. In contrast, demand in the automotiveindustry is growing, especially the demand for aluminum in New Energy Vehicles (NEVs). From there,we selected 51 automotive brands from around the world for research.Ofcourse, an important foundation for this research is that China has vigorously promotedwork related toproduct carbon footprints in the past few years. Some research institutionsin the automotive industry, such as "China Automobile industry chain carbon publicityplatform" (CPP), have done more detailed research on the carbon footprints of automotiveproducts, calculating the footprints for hundreds of vehicle models and thousands of cartrims. We also cooperate withCPPon data. Editor's Note: "China Automobile industry chain carbon publicity platform" refers to the ChinaAutomotive Industry Carbon Public Platform (https://www.auto-cpp.com/), which publishes carbonfootprints for some complete vehicles, components, and automotive materials. In terms of product carbon footprints,we have long cooperated with China CityGreenhouse Gas Working Group(CCG),China Products Carbon Footprint Factors Database(CPCD), and multiple Chinese andoverseasEPD and industry organizations todeveloptheProduct Carbon Footprint Disclosure and Catalogue(PCFD)which integrates data fromenterprises, relevant institutions, literature, and other sources. Currently, PCFD has about42,000 data entries, consisting of carbon footprint datafromconsumerproducts(includingautomobiles) disclosed by enterprises and calculated by third-party institutions. This laid thefoundation forfurtherresearchonthe product carbon footprints of different carbrandsthrough upstream steel and aluminum consumption, andthusprovided conditions for us toevaluate the climate actionperformance of 51 automotive brandsviathe Corporate ClimateAction Transparency Index(CATI Index). Editor's Note:Product Carbon Footprint Disclosure and Catalogue(PCFD),https://www.ipe.org.cn/LifeCycleAssessments/List.aspx, provides retrieval tags for clothing, food,housing, transportation, daily use, as well as industry, agriculture, and services, facilitatingstakeholders to screen and retrieve product carbon footprint data calculated and publicly disclosed byenterprises based on Life Cycle Analysis (LCA) principles. The Corporate Climate Action Index(CATI)refers to a dynamic evaluation of enterprise carbonmanagement and emissionsreduction implementation across five dimensions: governancemechanisms, measurement & disclosure, carbon target setting, carbon target performance, andemissionsreduction actions. During this evaluation process, we also try to communicate with these brands, includingconfirming s
