Using a sample of 430 participants from different generations, distinct patterns of environmental engagement were identified. Younger generations, such as Millennials and Generation Z, stood out for their increased emotional involvement with environmental issues, reflected in higher levels of concern about human impact on the environment. Conversely, older generations, such as Baby Boomers and Generation X, demonstrated greater consistency in sustainable practices, such as recycling and purchasing organic products, often linked to financial stability and social norms. Among the mediating variables, sustainable values, beliefs, and contact with nature had the most significant positive impacts on sustainable concerns. In contrast sustainable knowledge and intentions versus attitudes showed less pronounced effects. These findings highlight a gap between theoretical knowledge and practical behaviour, often shaped by social and institutional barriers. The study underscores the importance of educational interventions and public policies that foster emotional and ethical connections to the environment, encouraging the transformation of intentions into actions. Moreover, the results emphasise the need for intergenerational collaboration to tackle global climate challenges, promoting an inclusive and conscious approach that ensures a sustainable future for all generations.engGenerational AnalysisIntergenerational SustainabilityPro-environmental BehaviourEnvironmental ResponsibilitySustainable PracticesBehavioural MediationSociodemographic InfluencesEnvironmental BeliefsSustainable ConcernsSDG 11 - Sustainable cities and communitiesSDG 12 - Responsible production and consumptionSDG 13 - Climate actionSDG 15 - Life on landSDG 17 - Partnerships for the goalsmaster thesis203921399
