Calculation of the component

The Federal Environmental Agency (UBA) annually publishes data on GHG emissions in the series „Nationale Trendtabellen für die deutsche Berichterstattung atmosphärischer Emissionen seit 1990, Treibhausgasemissionen“ . The item „Gesamt-Emissionen ohne CO₂ aus LULUCF“ was chosen for the NWI.


An amount of 80 euro per ton of CO₂ is used for the average external damage costs per ton of CO₂ – again negative impacts on climate and health as well as material damages and crop failure should be considered – as published in the UBA’s methodological convention 2.0 (“Methodenkonvention 2.0) for the estimation of external environmental costs.

The value of the external damage costs is annually deducted from the welfare index.
