Preset calculation parameters are based on typical operating conditions and can be adjusted by the user to provide even more accurate results for their specific application.
A CO₂ equivalent (CO₂e) is a unit to standardize the climate effects of various greenhouse gases. Thus, different mixtures of greenhouse gases emissions can be compared.
This is the sum of all CO₂ equivalents emitted for the production of the rolling bearing, including necessary resources and energy.
