Resumen (inglés):
IEC TR 62921:2015(E) outlines detailed guidance to streamline the quantification of greenhouse gas emissions for computers and monitors. It provides specific guidance for the use of streamlining techniques that minimize cost and resources needed to complete greenhouse gas emissions quantifications. In addition, the product category rules (PCR) section of this Technical Report recommends "state-of-the-art" process and data assumptions in order to reduce uncertainty. Lastly, this Technical Report provides an example of how a calculation could be performed.
