Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.
Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.
To better understand the relative magnitude for each indicator result of the product system, the so-called normalization can be carried out. This calculation step transforms an indicator result by dividing it by a selected reference value (e.g. total emissions for a given area). Another helpful step in LCIA to internalize the decision maker’ values is the weighting of indicator results. The different impact categories (environmental concerns) get numerical factors based on value-choices.
An Interpretation of the results of the second and third step completes the study by giving recommendations and evaluating the study in general.
The following pages enable you to find out more about the procedure and the individual steps of an environmental Life Cycle Assessment.
China began to pay attention to environmental protection two decades ago. In 1988, it made the State Environmental Protection Bureau a vice-ministry level organization administered directly by the State Council, China’s cabinet. Ten years later, the government elevated the bureau to a ministry-level organization, the State Environmental Protection Administration.
