The way people consume is shaped by attitudes, routines and the organisation of everyday life. Thus, strategies for sustainable consumption must start from a consumer perspective and have to take different everyday life practices and situations into account. Drawing on their own conceptual and empirical work, the authors outline a conceptual and methodological framework for social-ecological consumption research, linking lifestyle analysis to the study of everyday behaviour and environmental impact assessment. Based on this framework, a typology of nutrition styles and their environmental impact is presented, resulting from a representative survey about nutrition habits in Germany.
