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

This International Standard provides a harmonized methodology for calculating 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 standard 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.
Since lime is defined as the generic name for quicklime, dolime and sintered dolime, plants manufacturing at least one of these products shall be covered by this standard.
This International Standard addresses all of the following direct and indirect sources of GHG included as defined in ISO 14064-1:
— direct greenhouse gas emissions (ISO 14064-1 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 (ISO 14064-1 5.2.4 b) from the generation of imported electricity,
heat or steam consumed by the organization;
— other indirect greenhouse gas emissions (ISO 14064-1 5.2.4 c-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 standard
This International Standard is to be used in conjunction with ISO 19694-1:20xx, 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 standard to the sector-specific standards ensures accuracy, precision and reproducibility of the results and is for this reason a normative reference standard. Together these standards provide a harmonized method for:
a) measuring, testing and quantifying methods for GHG emissions;
b) assessing the level of GHG emissions performance of production processes over time, at production sites;
c) establishment and provision of reliable, accurate and quality information for reporting and verification purposes.

GHG emissions offset mechanisms, including but not limited to voluntary offset schemes or nationally or internationally recognized offset mechanisms, shall not be used at any point in the GHG assessment according to this standard.

This International Standard provides a harmonised methodology for calculating GHG emissions from the ferro-alloys industry based on the mass balance approach. It also provides key performance indicators over time of ferro-alloys plants. It addresses the following direct and indirect sources of GHG:
— (Direct GHG emissions (14064-1 5.2.4 a – former Scope 1 -) 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 from (14064-1 5.2.4 b – former Scope 2 -):
— The generation of purchased electricity consumed in the company’s owned or controlled equipment
This standard shall be used in conjunction with ISO 19694-1:20XX 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 standard to the sector-specific standards ensures accuracy, precision and reproducibility of the results and is for this reason a normative reference standard. The requirements of these standards do not supersede legislative requirements.
