The concept of open government has promoted several initiatives in order to progress in their implementation in different governmental agencies. Generally, implantation is carried out, in the first place, based on transparency and the opening of data, giving citizens relevant information about their community. Within that information, data about the rational use of natural resources and care of the environment can be found. In this context, and taking into account the ongoing analysis, it was discovered that, apart from the positive measures taken for the progress of the implantation, the main existing flaw is the possibility to link and relate the existing data in different data sources. The linking of data will allow for a closer analysis that can generate a wider context for information. This paper is based on a PhD thesis in process whose aim is to generate a framework that allows the linking and relationship of information related to the environment published in different open government portals.
