China's transportation sector is experiencing a rise in carbon emissions, with public transportation projected to reach its carbon peaking target by 2035. To accelerate decarbonization, collaboration between the public transportation industry and renewable energy manufacturers, specifically in hydrogen fuel cell vehicles (HFCV), is essential. Adjusting energy strategy, revenue structures, and consumer behavior post-pandemic is crucial to encourage the shift towards sustainable public transportation. Energy structure adjustment, focusing on low and zero-carbon energy sources like hydrogen, is key for emission reduction and ensuring future carbon peaking and neutrality goals in the industry.
