Life Cycle Assessment interpretation

Life cycle assessment is defined by ISO 14040 as compilation and evalu ation of inputs, outputs and the potential environmental impacts of a product system throughout its life cycle. The ISO standards regulate the procedural aspects of LCA. They do not, however, provide all the information required for carrying out an LCA study. The main phases of LCA are goal and scope definition, inventory, impact assessment, and interpretation. The various applications of LCA are not regulated by the standard (Fig. 15.1).

In single-species assessments, the interpretations of mixture assessments tend to be mostly absolute. Hence, risk assessors often focus on particular species and particular compound groups (e.g., risks of PCB mixtures for birds), allowing them to interpret and explain their experimental data to the best of their abilities. On the other hand, many risk assessors apply mixture extrapolation methods to address risks for communities. The applications of SSD-based methods for this evolved fast and now cover a wide set of approaches, ranging from ecological multiple-stress analyses to overall approaches such as life-cycle assessment. Especially in the latter set of approaches, the risk assessor can often allow the method to only yield relative...

Life-Cycle Interpretation is the phase of life-cycle assessment in which the findings of either the inventory analysis or the impact assessment, or both, are combined in consistence with the defined goal and scope in order to reach conclusions and recommendations. 

Life cycle assessment(s) (LCA) is a tool for assessing the environmental aspects and potential impacts associated with products or services. LCA involves compiling an inventory of inputs and outputs of the relevant product system, which are then evaluated, along with interpretation of the results of the inventory analysis and impact assessment in relation to the objective of the study, to determine the potential impact of the product/service on the environment [19]. 

Life cycle assessment is a methodology to assess the environmental impacts of a product, process, or service. ISO 14040 and 14044 are international standards for developing LCA, which has four steps that include definition of goal or scope, inventory of relevant material and energy inputs and relevant environmental outputs, evaluation of environmental impacts per functional unit, and interpretation of results. 

Life cycle assessment can be used to evaluate the environmental impacts of several plastic materials used for clamshells. The LCAs will follow the ERA four-step process. The LCAs will provide a goal, LCI, LCA, and interpretation. The LCAs will be compared for the LCA results and the process to develop the LCAs. 

Life cycle assessments (LCAs) consist of four independent elements (II) 1) definition of goal and scope 2) life cycle inventory analysis 3) life cycle impact assessment and 4) interpretation.

Life Cycle Interpretation. The results obtained within the Life Cycle Inventory and/or the Life Cycle Impact Assessment are interpreted in the light of the Goal and Scope Definition (e.g., by means of sensitivity or uncertainty analyses) in order to draw conclusions and make recommendations. ... 

The aim of the Life Cycle Impact Assessment (LCIA) is to facilitate the interpretation of the results of the inventory analysis. The result of the inventory analysis is an emission profile for each alternative system. In this study the emission profile is the total of all emissions to air, water and soil from the grave-to-cradle chain for the use of cushion vinyl floor covering, including the up chain processes, like electricity production and the down chain processes, like the incineration and landfill of the waste. Such an emission profile may consist of hundreds of emissions and extractions. In LCA impact assessment the total of interventions (emissions, extractions) of a process chain is evaluated in terms of environmental problems (impact categories).
