Current Situation in China: Carbon emissions from cold chain transportation are increasing by 8-10% annually (approximately 120 million tons of CO₂ in 2023)

Emission Structure:

Transportation: 58% (refrigerated truck/ship/engine fuel)

Warehousing: 32% (cold storage refrigeration)

Packaging: 10% (foam boxes and other materials)

2. Identification of Key Pain Points
   Pain Point Type Specific Manifestations Difficulties in Carbon Reduction
   Technical Limitations: Traditional refrigerants have high GWP values (e.g., R404A = 3922)
   High costs of alternative technologies
   Energy Structure: Diesel refrigerated trucks account for over 70%
   Insufficient electrification infrastructure
   Operational Model: Empty load rate >30%
   Difficulty in cargo integration
   Lack of standards
