ISO/TC 146/SC 1/WG 30 - GHG energy-intensive industries – Specific sectors

This document provides a methodology for calculating greenhouse gas (GHG) emissions from the semiconductor and display industry. This document includes the manufacture of semiconductor devices, microelectromechanical systems (MEMS), photovoltaic (PV) devices and displays. This document allows to report GHG emissions for various purposes and on different bases, such as a per-plant basis, per-company basis (by country or by region) or an international group basis. This document addresses all of the following direct and indirect sources of GHG: — direct GHG emissions [as defined in ISO 14064-1:2018, 5.2.4 a)] from sources that are owned or controlled by the company, such as emissions resulting from the following sources: — process: fluorinated compound (FC) gases and nitrous oxide (N2O) used in etching and wafer cleaning (EWC), remote plasma cleaning (RPC), in situ plasma cleansing (IPC), in situ thermal cleaning (ITC), N2O thin film deposition (TFD), and other N2O using process; — fuel combustion related to equipment and on-site vehicles, room heating/cooling; — fuel combustion of fuels for on-site power generation; — indirect GHG emissions [as defined in ISO 14064-1:2018, 5.2.4 b)] from the generation of imported electricity, heat or steam consumed by the organization. Other indirect GHG emissions [as defined in ISO 14064-1:2018, 5.2.4 c) to f)], which are the consequence of an organization’s activities, but arise from GHG sources that are owned or controlled by other organizations, are excluded from this document.

This document provides a harmonized methodology for calculating GHG emissions from the ferro-alloys industry based on the mass balance approach. This document also provides key performance indicators over time for ferro-alloys plants. This document covers the following direct and indirect sources of GHG: — direct GHG emissions [see ISO 14064-1:2018, 5.2.4 a)] from sources that are owned or controlled by the company, such as emissions resulting from the following sources: — smelting (reduction) process; — decomposition of carbonates inside the furnace; — auxiliaries operation related to the smelting operation (i.e. aggregates, drying processes, heating of ladles, etc.); — indirect GHG emissions [see ISO 14064-1:2018, 5.2.4 b)] from the generation of purchased electricity consumed in the company’s owned or controlled equipment.

This document provides a harmonized methodology for calculating greenhouse gas (GHG) emissions from the lime industry. It includes the manufacture of lime and any downstream lime products manufactured at the plant, such as ground or hydrated lime. This document allows for reporting of GHG emissions for various purposes and on different basis, such as plant basis, company basis (by country or by region) or international organization basis. This document addresses all of the following direct and indirect sources of GHG included as defined in ISO 14064-1: — direct greenhouse gas emissions [see ISO 14064-1:2018, 5.2.4 a)] from greenhouse gas sources that are owned or controlled by the company, such as emissions resulting from the following sources: — calcination of carbonates and combustion of organic carbon contained in the kiln stone; — combustion of kiln fuels (fossil kiln fuels, alternative fossil fuels, mixed fuels with biogenic carbon content, biomass fuels and bio fuels) related to lime production and/or drying of raw materials; — combustion of non-kiln fuels (fossil kiln fuels, mixed fuels with biogenic carbon content, biomass fuels and bio fuels) related to equipment and on-site vehicles, heating/cooling and other on-site uses; — combustion of fuels for on-site power generation; — indirect greenhouse gas emissions [see ISO 14064-1:2018, 5.2.4 b)] from the generation of imported electricity, heat or steam consumed by the organization; — other indirect greenhouse gas emissions [see ISO 14064-1:2018, 5.2.4 c) to f)], which are a consequence of an organization's activities, but arise from greenhouse gas sources that are owned or controlled by other organizations, except emissions from imported kiln stone, are excluded from this document. This document is intended to be used in conjunction with ISO 19694-1, which contains generic, overall requirements, definitions and rules applicable to the determination of GHG emissions for all energy-intensive sectors, provides common methodological issues and defines the details for applying the rules. The application of this document to the sector-specific standards ensures accuracy, precision and reproducibility of the results.

This document specifies a harmonized methodology for calculating greenhouse gas (GHG) emissions from the cement industry, with a view to reporting these emissions for various purposes and by different basis, such as, plant basis, company basis (by country or by region) or even international group basis. It addresses all the following direct and indirect sources of GHG included: — Direct GHG emissions [ISO 14064-1:2018, 5.2.4, a)] from sources that are owned or controlled by the organization, such as emissions that result from the following processes: — calcinations of carbonates and combustion of organic carbon contained in raw materials; — combustion of kiln fuels (fossil kiln fuels, alternative fossil fuels, mixed fuels with biogenic carbon content, biomass and bioliquids) related to either clinker production or drying of raw materials and fuels, or both; — combustion of non-kiln fuels (fossil fuels, alternative fossil fuels, mixed fuels with biogenic carbon content, biomass and bioliquids) related to equipment and on-site vehicles, room heating and cooling, drying of MIC (e.g. slag or pozzolana); — combustion of fuels for on-site power generation; — combustion of carbon contained in wastewater; — Indirect GHG emissions [ISO 14064-1:2018, 5.2.4, b)] from the generation of purchased electricity consumed in the organization’s owned or controlled equipment; — Other indirect GHG emissions [(ISO 14064-1:2018, 5.2.4, c) to f)] from purchased clinker. Excluded from this document are all other ISO 14064-1:2018, 5.2.4, c) to f) emissions from the cement industry.

This document specifies a harmonized method for calculating the emissions of greenhouse gases from the electrolysis section of primary aluminium smelters and aluminium anode baking plants. This document also specifies key performance indicators for the purpose of benchmarking of aluminium and boundaries.
