BASF’s Eco-Efficiency Analysis Methodology
The purpose of this submission is to establish BASF Corporation’s methodology for performing Eco-Efficiency Analyses for the intent of having it validated under the requirements of NSF Protocol P352, Part A: Validation of an Eco-Efficiency Analysis Methodology.
It is the intent of BASF Corporation to use the same validated eco-efficiency model to conduct several individual eco-efficiency studies and have those studies submitted to NSF for verification under NSF Protocol P352, Part B: Verification of Eco-Efficiency Analysis Studies.
Content of this Submission
This submission specifies the minimum content of an Eco-Efficiency Analysis (EEA) conducted in accordance with BASF Corporation’s EEA (BASF EEA) methodology, and includes the environmental and economic parameters considered, the weighting and normalization procedures to quantify the environmental burden (environmental footprint) and economic costs (life cycle costing), as well as the process by which the data are evaluated for appropriateness and quality, followed by the options for presenting results and conclusions.
As required under NSF P352 Part A, BASF is submitting both a written document describing the elements of the BASF EEA methodology, and a computerized model that incorporates these elements into a working system. Enclosed with this document is BASF_EEA_Mastersheet.xls that is the computerized model programmed in Microsoft Excel.
BASF’s EEA Methodology
Overview: The process for performing a BASF EEA has been previously published and it involves measuring the life cycle environmental impacts and life cycle costs for product alternatives for a defined level of output. In other words, a BASF EEA evaluates both the economic and environmental impacts that products and processes have over the course of their life cycle. The methodology was created by BASF, in partnership with an external consultant, and has since been further developed. BASF EEA is based upon the ISO 14040 standard for life cycle analyses, however in addition to this standard, it includes additional enhancements that allow for the expedient review and decision-making at all business levels. Since its inception in 1996, BASF has completed nearly 400 analyses on a wide variety of products and processes. At a minimum, BASF EEA evaluates the environmental impact of the production, use, and disposal of a product or process in the areas of energy and resource consumption, emissions, toxicity and risk potential, and land use. The EEA also evaluates the life cycle costs associated with the product or process by calculating the costs related to, at a minimum, materials, labor, manufacturing, waste disposal, and energy.
