Accuracy
Data should be sufficiently precise to enable
intended users to make decisions with reason-
able assurance that the reported information is
credible. GHG measurements, estimates, or cal-
culations should be systematically neither over
nor under the actual emissions value, as far as
can be judged, and that uncertainties are
reduced as far as practicable. The quantifica-
tion process should be conducted in a manner
that minimizes uncertainty. Use of the calcula-
tion guidance provided in the Climate Leaders
Core Modules, coupled with development of the
Climate Leaders Inventory Management Plan, can
significantly enhance data accuracy and trans-
parency as well as promote credibility.
