"Low-carbon certification" in the era of carbon neutrality!

Low-carbon service certification refers to the conformity assessment activities in which the certification body proves that the greenhouse gas emissions of the product meet the corresponding low-carbon product evaluation standards or technical specifications.

 

Product carbon footprint

ISO 14067

The carbon footprint of a product is the total amount of direct and indirect greenhouse gases released by a product (or service) during its entire life cycle (often referred to as cradle to grave, i.e. from extraction and processing of raw materials, to production and packaging, marketing, use, reuse and product maintenance, to recycling and final waste disposal).

The main greenhouse gases accounted for include: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and hexafluoride (SF6).
