Wirkungsökonomie (WÖk) is a framework for aligning economic, government and societal decisions with their real-world consequences for people, the environment and democracy. Its central principle is that decisions should be judged not only by what they deliver, but by whether they genuinely improve living conditions, prevent harm and distribute effects fairly. The approach encourages organizations to define problems and goals, examine how actions may produce change, compare alternatives and check results over time, including unintended consequences and risks.

WÖk presents its model through accessible explanations, practical examples and more detailed methodological guidance. Its website offers learning resources, tools and an example of impact controlling, alongside books, technical papers and a library. It also provides information for different audiences and roles, invites questions and debate, and encourages participation in developing the framework. WÖk builds on existing sustainability, evaluation and public-sector review approaches rather than claiming to replace them. It aims to connect these elements in a consistent process that supports transparent decisions, evidence-based assessment and ongoing learning.
