Providing consumers with product-specific environmental impact information for food products (ecolabels) may promote more sustainable purchasing, needed to meet global environmental targets. This UK study (N = 1051 participants) investigated the effectiveness of different ecolabels using an experimental online supermarket platform, comparing three labels against control (no label). Significant reductions were found in the environmental impact score (EIS) for all labels compared to control (labels presented: values for four environmental indicators [-3.9 percentiles, 95%CIs: -5.3, -2.6]; a composite score [taking values from A to E; -3.9, 95%CIs: -5.2,-2.5]; or both together [-3.2, 95%CIs: -4.5, -1.9]). Providing ecolabels is a promising intervention to promote the selection of more sustainable products.
为食品产品（生态标签）提供特定于产品的环境影响信息，可以促进更可持续的购买，这是实现全球环境目标所必需的。这项英国研究（N=1051 名参与者）使用实验性的在线超市平台调查了不同生态标签的有效性，将三种标签与对照组（无标签）进行了比较。与对照组相比，所有标签的环境影响评分（EIS）都显著降低（标签展示：四个环境指标的数值[-3.9 个百分点，95%置信区间：-5.3，-2.6]；综合评分[从 A 到 E 取值；-3.9，95%置信区间：-5.2，-2.5]；或两者同时[-3.2，95%置信区间：-4.5，-1.9]）。提供生态标签是一种很有前途的干预措施，可以促进选择更可持续的产品。
