Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

1 ​Scope

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.
