The paper, which is part of a parallel study between Mexico and Spain, analyzes the environmental information requests that are made by users in the Spanish public sector bodies. Furthermore, a webcrawler, which was designed for this purpose, analyzes many parameters of the information displayed on the website of 30 environmental public bodies such as the number of documents, providers, types of environmental information, document formats ... Results highlight the use of metatags instead of metadata and descriptor analysis shows a lack of relationship between the requests and the descriptors which are used to identify such information on the Web.
