This paper describes the design of an innovative approach to teaching and learning academic communication and intercultural linguistics in the English Studies field to foster competencies for participation in the Digital Society. More specifically, we describe the learning outcomes, sequence of tasks and assessment of competencies for an itinerary of collaborative multimodal online tasks focused on the creation of a Citizen Science (CS) project linked with SDGs. These tasks drew on a genre-based pedagogy and task-based learning in connection with language and digital competencies. We conclude that the integration of CS and SDGs in the educational objectives of the course enables us to embrace the digital transition by promoting open and innovative education and training in transversal skills, digital and intercultural communication, language mediation and English.
