Trying to quantify emissions related to a given activity requires
consideration of complete life-cycles. That means counting emissions
from all related activities, raw materials, transformed products and
necessary infrastructure (indirect emissions).
Naturally, one has to stop imputing indirect emissions to the
evaluated activity at some point. This will depend on the working
branch and on the assessment methodology used.
Direct measurements of greenhouse gases emissions
are not possible. Assessments are therefore using
precise theoretical calculations for each sectors. They
are called “emission factors” and are regularly
updated.
