In recent years, the Portuguese word ‘sustentabilidade’ (“sustainability”) has been widely used to refer to environmental issues, generally expressing the need for environmental preservation and regeneration to go hand-in-hand with the economic system in capitalist societies. At the same time, the term has acquired new senses in different domains, often derived figuratively from the source domain of the environment. As a result, especially with the wide spread of social networks, the word “sustainability” has entered a wide range of different discourses. In order to understand how the term is currently used in Brazilian Portuguese, as well as the discourses that it underlies, the current thesis addressed the following research questions: 1. How do Brazilians express the term sustainability in social media (Twitter) today?; and 2. Which dimensions represent the discursive use of the concept of sustainability in Portuguese?. Based on a theoretical and methodological framework comprising both Corpus Linguistics (BERBER SARDINHA, 2004) and French Discourse Analysis (MAINGUENEAU, 2008a; 2008b; 2013; 2015), we analyzed a corpus of 93,689 tweets posted by 42,503 different users, for the time period between 2018 and 2022. In order to detect the discourses in the corpus, we used Lexical Multidimensional Analysis (BERBER SARDINHA, 2016; 2017; 2019; BERBER SARDINHA, FITZSIMMONSDOOLAN, in prep.), which consists of identifying the correlated sets of lexical units in the corpus. As a result, eight lexical discursive dimensions were identified, each comprising different interdiscourses: Corporate culture vs. Scarce/unsustainable resource; Political concerns vs. Business concerns; Corporate concerns vs. Educational concerns; Clean energy vs. Marketing; Knowledge topic vs. Tangible credit; Local development vs. Global development; Environmental protection vs. Innovative business opportunity; and Agribusiness vs. Life's philosophy. This research project is part of the Multimodal/Multilingual Portal for the Advancement of Open Science in the Humanities (cienciaaberta.org). It contributed to the Portal in several different ways, for example by chronicling the research activities involved in the project, by making available the corpus, the computer scripts and the statistical programs developed for the project. In conclusion, it is hoped that the current project contributed both to widening our understanding of the discursive practices associated with sustainability, and to strengthening the open science movement in the Humanities in general and in in Applied Linguistics in particular
