Calculation: Stakeholder Carbon Footprint

Stakeholder Carbon Footprint

The motivation for climate protection and the assessment of the costs and benefits of various measures can differ significantly between the stakeholders.  


The stakeholder carbon footprint enables individual modeling of one's own assessments.


This allows the customized creation of a ranking list of the relevant emissions that can be influenced and the assessment of the assigned climate protection measures.


Stakeholder carbon footprint for the Schwehm family driving one car in 2020

Step 1: Defining the scope

A rough breakdown of emissions from the activity of driving a car should bring new the wind of change into the public climate debate


Step 2: Parameterization

Only the stakeholder groups are considered as stakeholders  

  • Individuals (Schwehm family)

  • Companies (car manufacturers, suppliers, energy companies, workshops,...)

  • Investors (owners, shareholders, asset managers,...)

  • Politics/NGOs (federal government, local authorities, ADAC, environmental organizations,...)  


Step 3: Relevant individual emissions

According to VW, the CO2 emissions of our VW Sharan 1.4 TSI are 156 g/km. In reality, however, using your own car leads to a large number of other emissions:


  • Higher real consumption

  • Gasoline production

  • Automobile production 

  • Scrapping

  • Sales & Maintenance

  • Road construction

  • Police, ambulance, fire department


Step 4: Life Cycle Assessment

To determine the ecological balance of the VW Sharan, estimates are made for the relevant historical individual emissions and are divided according to the selected parameterization.  


Step 5: Data Collection

In 2020, 8000 km were covered with an average consumption of 8.5 l


Step 6: Weighting

For the analysis, the individual activities in


  • Production & Disposal

  • Operational emissions

  • Fuel supply

  • Sales, Maintenance & Infrastructure


were divided.


For each of these groups, the benefits & influence of the different stakeholders were estimated. (see below)

Step 7: Analysis

The stakeholder carbon footprint of the Schwehm family’s driving activity for the year 2020 now results from

the selected parameterization


Collaboration: Best Practice Club

With Calcolution we would like to work with various associations, clubs and public bodies to create a platform together to exchange information on sustainability issues.


Companies, investors and institutions have very similar requirements when it comes to creating analyses:


  • Easy data collection

  • Validated Sources

  • Use of common standards

  • High flexibility through customization

  • Appealing design

  • Good usability

  • Comparability with peers

  • Low costs


Against this background, it is surprising that a large number of individual solutions are currently being implemented in individual projects by the various stakeholders. Broad cooperation between actors and initiatives could significantly increase efficiency and significantly reduce costs for the individual.

Become a Calcolution partner, share your experiences with others and benefit from the shared use
of data and cooperation tools as part of the open source concept.

Comparison of different corporate carbon footprints in the financial industry

Due to the different choice of system boundaries (e.g. which Scope 3 emissions are taken into account and how), comparability between individual organizations is often difficult. Global standards (GHG Protocol, GRI, SBTI or PCAF) try to improve this.  


A simple analysis tool with interfaces to the standards mentioned could significantly increase the comparability and benefit of a cooperation. Incidentally, such a tool can be used for several industries with a slightly modified parameterization.


The greatest difficulty here is a common parameterization of the calculation method, since this strongly influences the results.


It is also possible to expand the system boundaries and calculate a stakeholder carbon footprint.
However, this further increases the complexity of the coordination and should therefore only be tackled as a second step.

Peer comparisons at a high level of aggregation objectify and simplify cooperation considerably. Companies that want to develop into a sustainability leader have the opportunity to share their experiences and benefit from feedback from others.

Transparency is a crucial prerequisite for successful implementation.

In the further course of the project, the various tools are to be connected with one another so that measures can be identified on the basis of the stakeholder carbon footprint. These must then be checked by the stakeholder for their feasibility.


The assessments of the benefit and effort can differ significantly depending on the stakeholder, and an adjustment option for the standard assessment enables the results to be individualized. Furthermore, there may be dependencies between the measures that must be individually considered in the final prioritization.

Calcolution is at the beginning of a long journey. Let us embark on it together and become a cooperation partner in concept development or in a pilot project.

The analysis results of the Best Practice Club can be excellently linked to measures from the Eco-Ideas Corner.  


There are different concepts for almost all emissions that can be used to reduce them.



Massive savings can often be achieved through technical advances and changes in procedures. In the medium to long term, this is usually also financially worthwhile, such as in steel production with green hydrogen  

Reduction & Transformation:

With all emissions, we should pay more attention to whether they are really necessary and, if necessary, look for alternatives. Car sharing, for example, is an excellent way to increase car usage, save costs and reclaim inner-city space.

Impact projects:

For the part of your own emissions that cannot be avoided through innovation and reduction, it makes sense to support impact projects. In this way, CO2 can be avoided at another point or it can be bound in the long term via carbon capture.  


There are currently many individual collections of links with great ideas, measures and individual projects in climate protection. However, it is quite difficult to get a structured overview, since categorization is very individual. Most people therefore have their own more or less well-structured collection of bookmarks.


With the Eco-Ideas Corner, Calcolution would like to provide a portal with interesting links. The Tableau prototype is currently based on our personal collection of links, a brief assessment and a clear categorization.


The portal is initially intended to collect feedback and other links in the prototype variant. In the summer, a committee is to be formed that will add new links at regular intervals and adjust the assessments if necessary.  


If funding opportunities arise with a corresponding interest, the portal could also be supplemented with a comment option or an asterisk system.


Initial talks are already processing, if you are interested please give us a short feedback .
