This is a method for evaluation to help organisations to assess the impact of their sustainability projects. It covers a variety of subjects such as food and clothes. The measurement instrument can be used for diverse projects that are being performed within the GAIA context or in similar projects. The measurement instrument takes into account the general indicators that are relevant for measuring behaviour and behaviour change. It also looks at the specific elements that are attached to each individual project.
After an extensive literature review, two students from Utrecht University developed this method for evaluating behavioural change.
The measurement instrument is available for download, but is only available in Dutch.
