Green open-access refers to a model of scholarly publishing where authors can share their research outputs, such as articles and data, in publicly accessible repositories. This allows anyone to read and use the work without subscription fees, promoting wider dissemination of knowledge. Authors typically upload their work after publication, often in compliance with the policies of their funding agencies or academic institutions. This approach contrasts with traditional publishing, where access is often restricted to paying subscribers. Green open-access supports the principles of open science, encouraging collaboration and innovation by making research findings available to a broader audience, including students, researchers, and the general public.
