Project period: 
November 2018 – June 2022

Funding agency:
Supported by Federal Ministry for the Environment, Nature Conservation and Nuclear Safety based on a decision of the German Bundestag

Sächsische Energieagentur (SAENA)


With the National Climate Initiative (NKI), the German Federal Ministry of the Environment promotes innovative projects related to climate protection. In collaboration with Energie-Konsens from Bremen, the climate protection and energy consulting agency Heidelberg - Rhein-Neckar-Kreis (KliBA) and the Saxon Energy Agency (SAENA), and within the framework of the project "Green Nudging" (FKZ: 03KF0072B), ConPolicy developed, implemented, evaluated and scaled nudges aimed at promoting climate-friendly behavior in companies.

Following a review of the current state of research on "green nudges", nudges were developed, implemented and tested in a pilot phase in ten companies. In addition, the project aimed at spreading in two selected model regions (Rhine-Neckar district and Saxony), as well as preparing materials for nationwide scaling. 

The NKI funding enabled the development and introduction of nudges in a corporate context, testing their effectiveness, and thereby expand the approach to a not extensively tested context (corporate climate protection).

ConPolicy was responsible for the following two work packages in this collaborative project:

  1. In one work package the current state of research was reviewed , a "nudge catalog" with suitable, already tested nudges compiled and a process aid was created to foster autonomous development of nudges in companies.
  2. In another work package, ConPolicy evaluated the implemented nudges for the purpose of providing proof of efficacy of the tested interventions. 

In addition, ConPolicy was involved in company workshops, in which tailor-made nudges were developed using a participatory approach.
