Double nudges can accelerate the transition towards more climate-friendly diets-experiment involving default meals and carbon footprint information

Key Points

• Participants showed a significant increase in selecting climate-friendly diets with double nudges—default meal options and carbon footprint awareness.
• The study highlighted a 30% higher selection of climate-friendly options when nudges were applied together compared to one alone.
• Experimental intervention designed to assess the effectiveness of nudging strategies through default meals and carbon impact information provided insights.
• These findings support using behavioral nudges to influence dietary choices, with potential implications for public health initiatives.
