Resume:   This article describes an impacting registered idea of using metal foam in conductors and other parts to increase rated currents, reduce weight, and improve performance for internal arc and temperature rise. It is a real proof that small and medium-sized companies can develop innovations without costly lab testing, just using low-cost computer test simulations. It includes a suggestion to the main technical standards-makers (IEC, ANSI and national ones), on how to signalize that product should be more efficient having  smaller weight/MVA, to save Earth resources. It would open doors for a  future “Environmental Efficiency Certificate for Electrical Products”. Our technical standards are concerned only with creating products that pass the tests, without considering whether they consume more resources than they could. The speech of standards entities on environmental issues is positive. To transform the speech in an objective action it could become mandatory to include, in all products standards, a statement about the KG / MVA transmitted by the product. I mean something like was successfully done in the late 80’s , for electromagnetic compatibility (EMC)
