Quantified Uncertainties in Comparative Life Cycle Assessment: What Can Be Concluded?

Quantified Uncertainties in Comparative Life Cycle Assessment: What Can Be Concluded?

Interpretation of comparative Life Cycle Assessment (LCA) results can be challenging in the presence of uncertainty. To aid in interpreting such results under the goal of any comparative LCA, we aim to provide guidance to practitioners by gaining insights into uncertainty-statistics methods (USMs). We review five USMs-discernibility analysis, impact category relevance, overlap area of probabili...

Treatment of Uncertainties in Life Cycle Assessment

Spurred by European Union directives along with increased interest among US initiatives, life cycle assessment (LCA) is becoming a common tool used in the measurement and evaluation of environmental performance and overall sustainability. Life cycle assessment is an analytical technique for assessing potential environmental, social, and economic burdens and impacts of a given product or process...

Can scientific quality be quantified?

" … The first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is o...

Can fisheries management be quantified?

Policy efforts to reduce fisheries impact have often created micro-management. Detailed regulations are restricting the fishing industry, and are also acknowledged to limit the progress towards sustainable management. Industry representatives, political bodies and scientists have therefore argued for more simplicity and transparency. Here, fisheries management is quantified in terms of trends i...
