ISO 19694-5:2023

OVERVIEW

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-
