We present survey data from 453 Swiss consumers. Data were collected in the German-speaking parts of Switzerland in February 2023 using an online panel provider. The survey included seven distinctive parts. In a first part, personal data including political orientation and consumption behaviour were collected. In a second part, participants assessed the current consumption in Switzerland regarding sustainability. Participants’ food sustainability knowledge was assessed in part three of the survey. In part four, participants rated a total of 19 policy measures for sustainable consumption for their acceptance. Part five dealt with actor responsibility. It included four questions to assess participants’ health consciousness. In part six, we measured participants’ environmental attitudes. In part seven, participants answered questions on who they think was responsible to take action to increase sustainability in consumption and how much trust they had in these actors to do this successfully. The research design was approved by the Ethics Committee of ETH Zurich (approval number: EK 2023-N-04).
