GB/T 48121-2026Greenhouse gases - Quantification methods and requirements for carbon footprint of product - Refrigeration and air-conditioning equipment (English PDF)

GB/T 48121-2026 is the English-translated version of 温室气体 产品碳足迹量化方法与要求 制冷空调设备.

This standard sets quantification methods and requirements for the carbon footprint of products in the refrigeration and air-conditioning equipment sector. It falls within the greenhouse gas series and helps companies calculate and report the emissions attributed to a product across its life. It is written for manufacturers of refrigeration and air-conditioning equipment, sustainability teams, verification bodies and buyers who ask suppliers for product carbon data.

It is a recommended national standard (GB/T), with the China Machinery Industry Federation as the responsible body, and it takes effect on 1 March 2027. As carbon disclosure requests increase from customers and regulators, a sector-specific national method lets suppliers prepare footprint statements on a consistent basis. Importers and exporters dealing with Chinese HVAC and cooling products may refer to it when interpreting footprint declarations.
