Kaufnix is a campaign launched by the Deutsche Umweltstiftung (German Environmental Foundation) to promote a more sustainable future beyond the pursuit of economic growth. Its central message is that sufficiency—using resources thoughtfully and reconsidering how much we consume—should guide personal choices, public policy and economic activity. The campaign aims to highlight practical examples of change and offer concrete ideas for reducing unnecessary consumption.

Through articles, guest contributions and interviews, Kaufnix explores sustainability across everyday life and society. Its coverage includes consumption, food, housing, mobility, education, digital technology, governance and economic growth. Recent topics consider ways to reduce food surpluses, shop more directly from producers, make communities and homes more resource-conscious, and understand how artificial intelligence affects resource use. The site also provides a searchable collection of content, with filters by format and subject, alongside resources such as a literature database and glossary. Kaufnix is therefore both an educational platform and a source of practical inspiration for people seeking to limit environmental impacts and support a society less dependent on continual growth.
