This keyword is always used in combination with “Corporate Carbon Footprint”, “Product Carbon Footprint” or “Life Cycle Assessment”.

Many organizations do their own calculation of their carbon footprint or life cycle assessment.

TÜV Rheinland has defined criteria to evaluate that the method applied by the license holder for:
(1) Calculating a Corporate Carbon Footprint according to ISO 14064, in conjunction with Greenhouse Gas Protocol, or
(2) Calculating a Product Carbon Footprint according to ISO 14067, or
(3) Calculating a Life Cycle Assessment according to ISO 14040/14044

is in conformity with the above-mentioned standards. This means the method is scientifically and technically valid, sufficient and in line with the requirements and criteria as set out in the applicable international standards, in their valid version.

The respective documented procedure for the calculation of the carbon footprints or the life cycle assessments is verified regarding plausibility and completeness. In addition, the calculation model applied is assessed regarding transparency, completeness and consistency.

The use of the keyword “Certified Calculation Method” confirms that the applied method fulfills the criteria set by TÜV Rheinland.
