The data quality matrix for product life cycle inventory data proposed inWhdkma &Wlsnaus (J. Cleaner Prod. (1996), 4: 167-174) was subjected to a multi-user test, in which 7 persons scored the same 10 datasets representing 10 different processes. Deviations among scores were listed, and the causes for deviations were determined and grouped into a limited number of well-defined classes. For the majority of the scores, the different test persons arrived at the same score. Deviations occur most… 

German network on life cycle inventory data

A permanent German ‘Network on Life Cycle Inventory Data’ will serve as the German information and cooperation platform for all scientific and non-scientific actors in the field of life cycle analysis and will integrate expertise on LCA in Germany, harmonize methodology and data, and use the comprehensive expert panel as an efficient basis for further scientific development and practical use of LCA.

A Dataset Quality Assessment—An Insight and Discussion on Selected Elements of Environmental Footprints Methodology

It is proposed to remove an impact-assessment-based step from the procedure of company-specific datasets quality assessment, resulting in a reduction in the need for expert knowledge and time savings and an example of raw milk production is presented.

Data quality and uncertainty assessment methodology for pavement LCA

Abstract In performing pavement life cycle assessment (LCA), users are facing various reports of energy intensity coefficient (EIC) of pavement materials which differ considerably among data sources

Comparing Data Management in LCI Databases

Life Cycle Assessment (LCA) is a widely accepted method for analysing the environmental aspects of goods and services. Life Cycle Inventory (LCI) datasets document the various involved material and

Data representativeness in LCA: A framework for the systematic assessment of data quality relative to technology characteristics

A shortcoming in current data quality assessment schemes is that the data quality information is not used systematically to identify the critical data in a life cycle inventory (LCI) model. In

Parameter Uncertainty Analysis of the Life Cycle Inventory Database: Application to Greenhouse Gas Emissions from Brown Rice Production in IDEA

The objective of this paper is to develop a simple method for analyzing the parameter uncertainty of the Japanese life cycle inventory database (LCI DB), termed the inventory database for

The creation, management, and use of data quality information for life cycle assessment

This discussion paper addresses revisions to assessing data quality captured in a new US Environmental Protection Agency guidance document as well as additional recommendations on data quality creation, management, and use in LCA databases and studies.
