1 Scope

China's national requirements for greenhouse gas emission accounting and reporting by thermal insulation material producers. It is Part 36 of GB/T 32151 and specifies the calculation steps, the accounting boundary and emission sources, the accounting requirements and emission calculation, the data quality management, and the content and format of the report, with a boundary schematic, a report format template, default parameter values, a steam enthalpy table, a data quality control plan template and a normative annex on the principles for selecting the electricity carbon dioxide emission factor. The sector it covers is a mixed one and that is what makes the accounting interesting. Thermal insulation materials divide into the mineral products - rock wool, glass wool and foamed glass - and the organic ones, principally expanded and extruded polystyrene and polyurethane foam, and the two are made by entirely different processes with entirely different emission profiles. Mineral wool is made by melting rock or glass in a cupola or a furnace at high temperature, which is a large fuel burn, and the raw materials include carbonates that decompose and release carbon dioxide chemically - a process emission that no change of fuel removes. Organic foams are made by expanding a polymer with a blowing agent, which is a far smaller energy operation but which historically used blowing agents that are themselves powerful greenhouse gases. The calculation clause therefore covers fossil fuel combustion, process emissions, and purchased and exported electricity and heat separately. The inclusion of exported energy is worth noting: a plant with a cupola or a boiler may export steam, and the standard nets that out rather than charging the producer for heat that someone else used. Issued on 29 September 2024 and in force since 1 April 2025.

This document specifies the calculation steps, calculation boundaries and emission sources, calculation requirements and emission standards for greenhouse gas emissions of thermal insulation material manufacturers. quantity calculation, data quality management requirements, and report content and format. This document applies to the accounting and reporting of greenhouse gas emissions by insulation material manufacturers.
