ISO 14044 ISO 14044:2006 is designed for the preparation of, conduct of, and critical review of life cycle inventory analysis (LCIA). It also provides guidance on the impact assessment phase of LCA and on the interpretation of LCA results, as well as the nature and quality of the data collected.

# data[].attributes.body
Life Cycle Interpretation is a systematic technique to identify, quantify, check, and evaluate information from the results of the life cycle inventory and/or the life cycle impact assessment.
The results from the inventory analysis and impact assessment are summarized during the interpretation phase. It includes
• Identification of the strong and the weak points based on the results of the LCI and LCIA phases
• Meeting the goals set during the first stage
• evaluation of the study considering completeness, sensitivity and consistency checks
• conclusions, limitations and recommendations.

The article "Life Cycle Analysis of Distributed Energy System Projects’ Energy Consumption and GHG Emission - A Case of Beer Brewery Auxiliary Power Supply in China ". Addresses a very important topic about an alternative to obtain renewable and environmentally friendly electrical energy, this is distributed energy, among which is wind, biomass, solar energy, among others.

In this study, a comparison was made between 6 cases, obtaining better results in the reduction of life cycle energy consumption and the production of CO2 emissions for both gas, biomass use and wind electricity, with lower scores for the two last.

It would be interesting to start applying more projects that include this type of energy, where it benefits different populations, taking into account what type of distributed energy can be applied and of course contributing to the environment.

• life cycle
consecutive and interlinked stages of a product system, from raw material acquisition or generation from natural resources to final disposal
• system boundary
set of criteria specifying which unit processes are part of a product system
• consistency check

The life cycle analysis (ACV) is an environmental evaluation methodology through which all the enviromental aspects of a product, process or service can be analyzed and quantified throughout its life cycle. The study includes all stages of its existence, that is, the stages that range from the extraction and processing of raw materials, their manufacture, transport, distribution, use, reuse or recycling and the final disposal of waste.  karen jimenez

The main function of a life cycle analysis is to provide information that helps to identify opportunities for improvement, in order to confront them with the associated risks and finally make the necessary decisions to improve environmental performance.

The International Standard ISO 14044 was prepared by the Technical Committee ISO / TC 207, Environmental Management, Subcommittee SC 5, Life cycle analysis.

The growing awareness of the importance of environmental protection, and the possible impacts associated with products1, both manufactured and consumed, have increased interest in developing methods to better understand and treat those impacts. One of the techniques developed in this regard is the life cycle analysis (LCA).

LCA can help (Hansi, Xiongwen, & Xunmin, 2017) .
