A selection of records is made based on three criteria forming the population of this use case. These criteria include: open access compliance, each of the publishing bodies will have already been assigned a ROR ID, and an individual’s email address is provided as the point of contact in the record. Ten of the 25 records in the PUBGREY registry adhere to the established criteria and form the population of our study. These are then asked to complete a brief online survey dealing with grey literature. The survey questions used in this study on climate change are the exact same as in a study three years earlier on circular economy. The reuse of the questionnaire was based on a recent working paper demonstrating how circular economy provides a strategy in achieving goals for climate change.

Both online surveys were carried out via SurveyMonkey
