‘The Gross National Product counts air pollution and cigarette advertising, and … the destruction of the redwood and the loss of our natural wonder in chaotic sprawl… Yet [it] does not allow for the health of our children, the quality of their education, or the joy of their play… the beauty of our poetry or the strength of our marriages… it measures everything, in short, except that which makes life worthwhile.’
1968

Starting point: Private consumption weighted with incomedistribution
+ welfare-creating components not included in the GDP, i.e. household and family work, voluntary work
+/- adjustments due to the temporal divergence of expensesand benefits of durable goods
- welfare reducing components: e.g. environmental impacts, traffic accidents, consumption of non renewables
Methodological Overview of the NWI

Conclusion
Why do we need an alternative welfare measure “beyond GDP”?Because GDP just measures economic output, and as the NWI and other studies (e.g. Daly/Cobb (1989), Kubiszewski/Costanza et al (2013),Bleys/Whitby (2015)) showed: Economic Output (GDP) is not a good estimator for welfare
Why do we need (also) a single indicator and not an indicator system?Because we need an indicator that can take on GDP. This by no means means that indicator systems are not necessary too. They are indispensable for responsible governing, but we also need a single indicator which is easy to communicate in the public and to politicians and which gives an indication of the overall development.
Next Steps: Methodological improvements; International harmonisation; Reducing time lag; Regular update and publication of NWI and RWI; Getting more federal states on board with RWI; Trying to make NWI/RWI and alternative welfare measurement more known/visible/relevant in Germany/Europe/Worldwide
