Purpose: Learning about sustainable development in dedicated curricula can be beneficial for students' personal and professional development and societies alike. However, for various reasons the implementation of sustainable development modules in existing curricula can be difficult in many fields of study. This paper aims to propose an alternative route to give students the chance to learn about sustainable development without the need to change the structure of their study program. Design/methodology/approach: The current paper elaborates on the idea that many fields of study have mandatory courses on empirical research methods and these courses can function as a platform to teach applied empirical research methods in combination with education on sustainable development. A three-phase model is proposed to implement sustainable development topics in existing curricula, taking students' current methodological competency level into account. Findings: The proposed model provides a chance to combine education on sustainability with thorough training in scientific research methods. Example projects and evaluation results from an existing social science curriculum and its integration into a real-world laboratory on sustainable energy use illustrate the different phases and their goals. Originality/value: The model offers the opportunity to implement education on sustainability into existing curricula without the need for difficult structural changes. It extends students' learning on sustainability without impairing their learning of research methods. A discussion of the model's limitations and boundary conditions helps to understand its potential use cases and challenges.
