Activity or process is also due to a methodology which serves to determine in a quantitative way the environmental alterations which are caused by the exercise where all the stages from the manufacturing to the end of the useful life must be taken into account. It can be affirmed that this type of tools allows to qualitatively measure the costs and benefits that a certain product or service can have in the environmental field. This serves as an instrument in the decision making for the continuous improvement of each one of the processes , in addition to warning and which is a prevention in the form or final disposition that must be carried out, it can also be said that the improvement of the conditions not only of the product or activity but also that the quality of life of the people who they are involved during the process.
Nowadays, processes that have an analysis of the life cycle of their products or services offer the consumer the guarantee of applying the ideal technology in the elaboration of that product. We can not ignore the fact that all anthropic activities generate an impact on the planet where they modify the natural conditions of the planet. If we analyze the situation we are facing, we can realize that it is chaotic and the processes are complex and which we have started being more visible since the industrial revolution, one of the clear examples is global warming, considerable decimation of species directly affecting biodiversity and cycles of biological control among many others, this is why we can say that methodologies of life cycle assessment are all the efforts that are made to minimize these impacts, which allow to visualize sustainable models not only environmentally but economically and socially.

The importance of environmental protection, and the impacts generated by manufactured or consumed products, lead us to adopt methods to minimize them, such as the LCA life cycle analysis. This analysis helps us to identify the environmental performance of a product in its different stages of life, provides information that leads us to plan the needs and redesign the products or processes according to their performance ISO 14044 gives us in detail what we need for a LCA this method treats all environmental aspects as impacts or possible impacts and all the consequences from the extraction of the raw material to its final disposal.
There are 4 phases of the life cycle analysis.
1.) Definition of the objective and scope: In this phase the objective of the study is defined depending on the subject and the use.
2.) Inventory analysis: it is based on an inventory of inputs and outputs data gathering of the necessary data according to the objectives of the defined study.
3.) Environmental impact assessment: provides information that helps us evaluate the results of the inventory to understand its environmental importance.
4.) Interpretation: in this stage the results are socialized, concluded and decisions are made according to the defined objective and scope.

Life cycle analysis becomes a mainstream of evaluation methods, investigates the emission difference between the energy system distributed and the traditional energy system; Gas-based projects are investigated in a wide range of aspects including economic value, environmental value and other values.

Gas based distributed energy has a desirable performance in environmental value. When compared to the traditional project the gas-based project seems to use a little more energy as input, but in a view of the life cycle, It reduces energy consumption significantly having a positive but limited effect on energy saving and reducing emissions

Life-cycle analysis treats environmental issues and potential environmental impacts, for example, the use of resources and the environmental consequences of emissions throughout the life cycle of a product from the acquisition of the raw material, going through production, use, final treatment, recycled, until its final disposition ie from cradle to grave.

There are four phases in a life cycle analysis study:

A) The definition phase of the target and the scope,

b) The inventory analysis phase,

c) The environmental impact assessment phase, and

D) the interpretation phase.

The importance that the care of the environment has taken in recent years in both public and private institutions in the development of study methods in which environmental impacts can be evaluated is as well as in the NTC ISO 14040 life cycle analysis (ACV) the norm gives the guidelines for carrying out the analysis process and proposes a follow-up of a 'product or service from the time it is born until the end of its useful life.
Stages for a life cycle analysis (ACV):
1. Definition of objectives and objectives
* Objectives
*Scope
2. Analysis of life cycle inventory
* Data collection:
* Data calculation
* Allocation of emissions and discharges flows
3. Life cycle impact assessment (EICV)
* Elements of the EICV
* Limitations of the EICV
4. Interpretation of the life cycle

Life cycle Analysis is a methodology for the definition of business and government strategies In the context of pollution prevention. Your system allows to interpret the environmental performance of an integrally analyzed unit, taking all the environmental impacts throughout the product's life cycle.

To determine the environmental impact through the life cycle basically consists of two parts, the life cycle inventory where all the parameters that can cause environmental effects are determined. The allocation of impacts where these parameters are related to previously established environmental categories.

In the article, it can be reported that the Life Cycle Analysis (LCA) method was used where it was possible to evaluate the energy consumption and GHG emissions of the Distributed Energy System projects. It shows that a study of the project of the Natural Gas Distributed Energy System of China was made, also you can see that you can make designs of other cases with different energy paths to do so and be able to compare your energy consumption and emission performance. You can find in the article that the result that the project shows us is that the Gas that saves is 8% of energy and reduces by 38% the GHG emissions where a comparison is made with the traditional project that uses coal and electricity of the network. It can be concluded that the effect of reducing emissions from renewable energy projects is not as significant as that of the project to Natural Gas, it can be said and what we could find is that renewable energy projects have the potential to develop in the future.
