有人建议，自愿或非自愿为食物贴上碳标签，可减少温室气体的排放。然而，关于这种标签对消费者购买的影响的经验证据有限。这项研究的目的是调查自愿碳标签是否会影响对牛奶的需求。在瑞典的17家零售店进行了一项随机现场实验，在那里，一个标志为消费者提供了关于气候认证牛奶的碳影响的定性信息。结果表明，该标志使对气候认证牛奶的需求增加了约6- 8%，并且该结果对替代模型规格具有鲁棒性。这种影响完全是由大型商店，如超市驱动的。我们没有发现对牛奶总销量的统计学显著影响，而且数据集太小，无法验证对其他牛奶品牌的影响。对标签牛奶需求的影响是短暂的。(C)2015作者由爱思唯尔有限公司发布
It has been suggested that carbon labelling of food, on voluntary or non-voluntary basis, could reduce emissions of greenhouse gases. However, there is limited empirical evidence on the influence of such labels on consumer purchases. The purpose of this study was to investigate whether voluntary carbon labelling affects the demand for milk. A randomized field experiment was conducted in 17 retail stores in Sweden, where a sign provided consumers with qualitative information about the carbon impact of climate-certified milk. The results suggest that the sign increased the demand for the climate-certified milk by approximately 6-8%, and the result is robust to alternative model specifications. The effect is entirely driven by large stores, such as supermarkets. We find no statistically significant impact on total milk sales, and the dataset is too small to verify the consequences for other milk brands. The effect on the demand for the labelled milk is short-lived. (C) 2015 The Authors. Published by Elsevier Ltd.
