ISO 14051 is part of the ISO 14000 family of standards relating to environmental management codified by the International Organization for Standardization. The purpose of ISO 14051:2011 is to provide principles and generic guidelines on material flow cost accounting. The norm seeks to provide a universally recognized paradigm for practitioners and companies employing material flow cost accounting. It is not intended for third parties certification.
ISO 14051 was published as a standard on the 2011, and provides a standard on the implementation of material flow cost accounting (MFCA). In MFCA energy can be accounted as part of the cost of flow of materials or separated. Many organizations are unaware of the real cost of loss of materials due to incomplete recording in traditional cost accounting. This norm aims to fulfill a gap providing a tool to use an integrate accounting perspective that helps to reduce environmental impact and financial costs.
ISO 14051:2011 provides general framework for the implementation of material flow cost accounting in small, medium and big organizations. In MFCA flow and inventories of materials are measured in physical amounts (i.e. mass, volume, liters, etc.) and the costs related with these flows are also taken into account and assessed. ISO 14051 is a tool of environmental management accounting and it provides information for internal use.
Cost estimation under ISO 14051:2011
In MFCA are estimated three kind of costs: (1) Material cost (2) System cost (3) Waste management cost.
Energy costs can be added to material costs or be quantified separately. Material, energy and system costs are assigned to cost centers outputs differentiating clearly which percentage belongs to final product and which percentage belongs to waste. The normative highlights the importance of a proper assignation criteria. Some criteria mentioned are number of hours of machine work, production, number of employees, number of hours of employees work, number of tasks completed, etc. in the estimation is needed to consider produce that is an output for a cost center but an input for another as well as internally recycled material.
- Step 1: Management level staff is needed to fully achieve environmental and financial objectives that are part of this framework. Managerial tasks are among others, leading implementation, providing resources, establishing follow up, reviewing results, decision making based on MFCA results.
- Step 2: As per its nature, MFCA needs a multi-disciplinar approach. A non exhaustive list of these knowledge and skills is: skills on design, purchases and production; engineering knowledge about processes, quality control, environmental expertise, cost accounting knowledge and skills.
- Step 3: Before starting it is needed to clearly define boundaries of study and time scope.
- Step 4: Cost center determination.
- Step 5: Identification of each input and output of every cost center.
- Step 6: Flow of material quantification in physical and monetary terms (both).
- Step 7: Summary of MFCA results and identification of areas of improvement to minimize waste.
Difference between MFCA and traditional cost accounting
Before the implementation of this particular ISO it is helpful to understand the difference with the traditional cost accounting. MFCA makes a record of material flow in physical and monetary terms and puts emphasis in the loss of materials (or in other words, the waste produced). Although traditional cost accounting recognizes loss of materials, waste management costs are not separated but integrated in the total cost of production. This practice makes difficult to identify easily and clearly which part of production is due to losses or waste generation. MFCA highlights waste management costs and inefficiency of processes therefore making easier to identify room for improvements. Many losses produce environmental impact (air pollution, water pollution, health problems, etc.) therefore identifying losses, the framework aims to make easier to also reduce some environmental impacts. It is worth saying that this framework does not identify environmental impact that is not linked with any material cost.
