In 2025, the Institute of Public and Environmental Affairs (IPE) and Green Jiangnan, together with 9 other environmental organizations, jointly launched the "Automotive Carbon Footprint Snap" campaign. Netizens on the Blue Map app participated actively, unlocking the product carbon footprints of over 110,000 vehicles through street photography, totaling over 4.12 million tons of carbon emissions. Among them, the total carbon emissions of Mercedes-Benz vehicles exceeded 270,000 tons, standing out significantly among hundreds of Chinese and foreign automotive brands. To accelerate the low-carbon transformation among automakers in China and to provide consumers with greener products, 11 environmental organizations jointly sent a letter to a group of leading brands. Some Chinese and foreign automakers responded positively, engaging in exchanges and discussions with the environmental organizations on relevant issues. However, regrettably, Mercedes-Benz has yet to make any response.
