LCAs positive side is that it allows to use very detailed processes than can give a very exact information about product, service or system that it is used for. However, on the negative side it is a long and time-consuming method as it involves gathering large amounts of data from throughout the supply chain or purchasing expensive databases. Approximately it is taking between 3 and up to 12 months for determining full results. Also, it is individual for each product, service or system, therefore it does takes a time to figure out which one is the best solution for a related product, service or a system. Therefore, it is a detailed but complicated and a long-term method. A simpler and a faster method is required, which brings to Electronics

It uses cumulative energy demand (CED) as a method to estimate the energy involved in the product manufacturing process, which energy is used as a proxy for all environmental impacts and employs simple and free datasheets. CED is also called as “primary energy consumption” [6] as it represents the value of energy usage that is required to produce a product, in case of the EEI project, electronic product. Therefore, it counts energy required to use to get metals from mines or quarries, this also includes impacts on soil, air, oil, etc., delivering them to a manufactures and energy required to manufacture the product on a production line. Since many of them are small items, the energy required for their production is still significant. For example, one common resistor with a weight of 0.17 grams has energy footprint of 119KJ that is equivalent to about 397 fist punches, 300 Joules each. This is a very rough but yet a clear approximation that can give a basic idea of how big is the environmental impact of one component could be. Therefore, it will be used as a basic concept for further calculations and usages in datasheets and in software part of the EEI project. EEI uses input parameters such as electrical components, components count and dimensions for solder equivalent. EEI skips most of LCA stages, since they cannot be applied to fast term
