The environmental concern is a part of the today's global agenda, namely due the negative impacts of human activities into the environment. This scenario has led to a creation of an awareness of the environmental issues and the sustainable concept in society. In this context, the environmental and sustainability education aims to promote a changing in attitudes and behaviours facing the environmental and social challenges, fostering an ethical and social responsibility sense. Moreover, it aims also to develop critical thinking in the society regarding the sustainability and other issues namely: climate changes and the protection of the biodiversity. Therefore, in order to raise awareness about the environmental and social challenges and to prepare the individuals for an active participation in devising adequate solutions, it is urgent to develop innovative transversal educative programs that encompass involve multiple understandings and dimensions and, combine distinct learning and teaching approaches, including non-formal learning. In this sense, the use of game-based learning (GBL) emerges as an innovative method that intends to break mane of the traditional teaching barriers and allow for reaching stronger student engagement. Escape rooms, as a GBL tool, have been gaining great space inside GBL strategies. This approach has been used in formal education by educators from different fields of knowledge. From these experiences are reported results that allow to conclude that these innovative strategies are an effective method to motivate and engage students in the teaching and learning process, and to foster the development of several key skills in students. The design of the puzzles and challenges, the hands-on experience, the immersive factor and the interaction provided through the activity, influence changes in knowledge, values and attitudes towards environmental behaviour and sustainability. This research has implications for the discussion on the most appropriate strategies for the implementation of educational escape rooms (EERs) to boost environmental education, namely in the context of formal education.
