1 Scope This document establishes general principles for addressing the sustainability of earth moving machinery as defined by ISO 6165, defines sustainability terminology, establishes important sustainability factors for earth moving machinery and gives examples of sustainability information reporting formats. This document applies to the development and manufacturing process, service life and end-of-life of earth moving machinery. 2 Normative references The contents of the following documents constitute essential provisions of this document by means of normative references in the text. Where a reference is dated, only the version corresponding to that date applies to this document; where a reference is not dated, the latest version (including all amendment sheets) applies to this document. 3 Terminology and definitions The following terms and definitions apply to this document. 4 Sustainability factors 4.1 General provisions The sustainability factors presented in Table 1 apply to earthmoving machinery in order to achieve a sustainable balance between the environment, society and the economy at the time of use and at the end of life. Service life usually has the greatest impact on this balance. These effects are taken into account in the development process and Table 1 presents information on the sustainability of machines at use and at end of life. The sustainability principles in ISO 14040 and ISO 14044 apply to both the machine development process and the manufacturing process. An assessment based on sustainability factors can provide information for the work site or work project. The assessment of work site energy efficiency (see 4.2) and greenhouse gas emissions (see 4.3) factors is best carried out at the actual work site or work project, where the total amount of energy/fuel used can be assessed relative to the amount of work done to complete the work project. Note: Due to the diversity of machines and the variability of operations (e.g. applications, driver skills or terrain), the valuation of energy use is not sufficiently precise to allow comparison between different machine models and specifications. 4.2 Jobsite energy efficiency The jobsite energy efficiency factor is the amount of energy consumed to complete a work project. It is usually expressed as the amount of energy consumed per unit distance of material moved. Common units are cubic metres per kilowatt hour (m'/kWh) or tonnes per kilowatt hour (t/kWh). For some applications, the distance the material travels is an important parameter and therefore the energy efficiency is given in cubic metres per kilowatt hour (m*/kWh) or tonnes per kilowatt hour (t/kWh). Determining the energy efficiency of a machine requires measuring its energy use and machine productivity. The workplace energy efficiency of an individual machine is estimated by comparing the energy use (fuel consumption) of the machine with the amount of work done. The amount of energy (fuel) used by a machine depends on the specific application and the machine load factor. Examples of estimating machine energy efficiency are provided in Appendix B. 4.3 Work site greenhouse gas emissions The earthmoving machinery jobsite greenhouse gas (GHG) emission factor refers to the GHG generated by the earthmoving machinery products used to complete the work project due to energy/fuel consumption. Jobsite GHG emission sources refer to earthmoving machinery used during a typical 8 h working period, excluding any additional stages in the product life cycle. It is appropriate to include GHG emissions from all forms of energy/fuel (e.g. fossil fuels, renewable fuels and electricity) in order to determine the total GHG emissions generated. HFC emissions are related to the servicing and leakage of air conditioners fitted to machines at the work site and are appropriately determined by the refrigerant charge in the air conditioners. 4.4 Product support to improve machine efficiency and utilisation Workplace energy efficiency and workplace GHG emissions can vary significantly depending on operator skill and the specific operations at the workplace. Operator training and jobsite management can improve the energy efficiency of machines. Manufacturers can provide operator training guidance and jobsite operation assistance to improve the efficiency of machine applications. Through these means, workplace greenhouse gas emissions can be reduced in the short term. Note: Experience shows that the most significant improvements in sustainability come from operator training and work site management. 4.5 Quality of machine gas emissions The machine gas emission quality factor is the engine emissions measured during the engine emission test. The machine gas emission quality factor is the engine emissions during the test. The gas emission quality factor is defined according to the engine emission levels for nitrogen oxides (NO), hydrocarbons (HC), carbon monoxide (CO) and particulate matter
