Qiu Jincao: Real-World Carbon Calculations Show BEVs and PHEVs Are Nearly Equal on Emissions | Gasgoo

At the 2026 China Automotive Decarbonization and Sustainability Summit, Qiu Jincao from PATAC presented data showing that battery electric vehicles and plug-in hybrids are nearly equal in lifecycle carbon emissions when real-world energy use is considered. He highlighted that a 110 kWh battery pack carries over 9 tons of CO2 before the car even drives, based on China's current power battery carbon footprint of 83.5 kg CO2 per kWh. This means large BEVs start with a significant carbon debt that the grid mix must pay off over time. Qiu also drew parallels between China's 2026 export challenges and Japan's 1981 trade barriers, suggesting overseas factory investment and localized supply chains as a path forward. On the engine front, he argued that even as batteries grow, the engine remains critical for plug-in hybrids. Data from 10,000 GL8 PHEV users showed 73.4% electric mileage, but the depleted battery scenarios define user experience. PATAC's ninth generation Ecotec engine achieves 43.26% measured peak thermal efficiency, improving fuel economy by over 10% when the battery is depleted. The takeaway: real world carbon accounting matters more than regulatory numbers, and powertrain diversification is not going away.
