Research On Alternative Fuel Life Cycle Sustainability Assessment

Since the 1987 World Commission on Environment and Development,Norway's first female prime minister put forward the concept of sustainable development,sustainable development has been more and more attention,which is now in government and corporate agenda,it exists in worldwide research and education.Kl?pffer(2008)first proposed a sustainable product life cycle assessment framework and assessment method for sustainable product life cycle has gradually become a valuable measurement tool product selection.In this paper,the concept and evolution of sustainable life cycle assessment,principles and components,procedural steps and integrated framework,technical models and application analysis.In concept and evolution portion LCSA framework Kl?pffer(2008)defined as a watershed,with the form,carding the history and development LCSA framework.Principles and explained some of the major components in the framework composition LCSA--LCA,LCC and S-LCA,which,LCA's early development,has formed an international standard,while LCC and S-LCA is still in the early stages of development.This article Sustainable Life Cycle Assessment(LCA)with the traditional life cycle assessment(LCA)were compared in the dimension and index system,analysis object technology framework,as well as aspects of the evaluation model for a detailed analysis and comparison,and using application case conducted a comparative analysis more intuitive.In terms of dimensions and metrics system,life cycle dimensions of sustainable evaluation will extend from the environment to the economy and society;in terms of analysis of the object,evaluate the product life cycle extended to sustainable meso and macro;the technical framework,the four-step model modify the three-step model;evaluation model to evaluate the model,the use of a triangular model,instrument panel and other self-contained model.To solve the problem of sustainable product decisions,life cycle sustainability assessment has begun to be applied to the evaluation of sustainable product design,manufacturing,marketing,and recycling and other various fields.Based on the introduction of life cycle sustainability assessment framework,focusing on life cycle sustainability assessment cases analyzing.Analysis showed that:(1)evaluation of life cycle sustainability assessment,environmental,economic and social dimensions of the selection and decision-making needs of the main objectives of the relevant decision-makers,environmental and economic dimensions of sustainable product life cycle Assessment Applications majority;(2)most life cycle sustainability assessment application process still used in environmental life cycle assessment of the four-phase technology framework(ie,objectives and scope definition,inventory analysis,impact assessment and interpretation phases).To be clear,the time and space dynamics,risk assessment and other aspects of the content of t life cycle sustainability assessment applications should be considered next.
