Open calculation models are calculation models whose logic, assumptions, source references, formulas and ranges are made public where possible. New Economy develops calculation models to make social costs, benefits, emissions, material impact and scenarios visible. Where possible, these models are published so that others can check, improve and apply the calculations.
What is made public where possible?
Where possible, New Economy publishes source references, assumptions used, calculation formulas, model structure, input fields, scenario settings, ranges, sensitivity analyses, model versions and the date of the latest update.
What is not made public?
Confidential client data, personal data, business-sensitive data, licensed source files, paid datasets that may not be republished and raw data without publication rights are not made public.
Open calculation logic, careful source data
The calculation logic is made as open as possible. Source data is only shared when this is legally and substantively allowed. This keeps a calculation traceable and checkable, without republishing confidential or protected data.

Frequently asked questions about open calculation models
Open calculation models mean that calculation logic, assumptions, source references, ranges and model versions are published where possible. This makes calculations checkable, repeatable and reusable.
Confidential client data, personal data and licensed source data are not republished. In those cases, the source or method used is stated without republishing the underlying data.
Transparent calculation models make calculations checkable and increase trust in the outcome. Open assumptions and sources also make improvement and reuse by others possible.
