Every year, the global consumption of raw materials increases. In the 19th century, only a few elements were extracted and used. Today the whole periodic table is practically used by society, and many of the considered “critical” or “rare” elements are used in green technologies.
Such technologies shall be the best answer to reduce carbon emissions and achieve the 2ºC limit of temperature increase, as agreed by the United Nations in the conference of the parties in Paris (COP 21). This situation is going to imply a drastic change in the energy sector, increasing the installed power of wind and solar technologies, as well as shifting from conventional to electric vehicles in the mobility sector. Yet this transition must be carefully accomplished as huge amounts of raw materials are going to be required, increasing the pressure on raw material availability.
