Freshness is a connected service.
A cold chain succeeds when temperature, handling, timing and responsibility remain coordinated from production to destination.

A refrigerated building is one link.
Temperature control must connect collection, pre-cooling, storage, transport and the receiving facility. A break at one handover can reduce the value of the whole journey.
Energy reliability, maintenance, packaging and staff practice are part of the system. Planning only the physical asset can leave important operating costs and responsibilities unresolved.

Begin with the product and the route.
Different products have different temperature ranges, shelf lives and handling needs. Start with the practical journey rather than a generic equipment list.

Product
Quality specification, handling requirements and acceptable transit time.
Route
Collection pattern, travel time, border procedures and destination capacity.
Operation
Power, maintenance, records, staffing and who responds to a failure.
A shared focus in Macao.
Green cold chains were part of the fourth forum’s Macao discussions in November 2025. The published Macau Consensus identified them as an area for continuing cooperation.
This historical focus gives WFA a practical bridge between food security, sustainable infrastructure and agricultural trade.
