Scope 3 has fifteen categories and you must screen all of them
What it says, in full
Fifteen. That is how many categories of scope three emissions the GHG Protocol defines, and a company in scope has to screen every one before deciding which matter. Not pick the easy ones. Screen all fifteen, report the significant ones against the standard's own criteria, calculate those from current activity data each year, and refresh the whole inventory at least every three years. Bindler publishes verified GHG inventory workbooks at bindler dot co.
The whole rule, with every article and the dates: read the guide.
Every figure here is computed or quoted from the regulation named in the guide, not recalled. Captions are on the video and the full narration is above, so nothing in it is only spoken.
