The recent proliferation of standards and labels for organic, fair-trade, locally produced, and healthy food products risks creating confusion among consumers. This study presents a standardized approach to developing a comprehensive sustainability label that incorporates ecological, economic, and social values. The methodology is based on an extension of modular life-cycle assessment to non-environmental sustainability criteria. Interviews with a wide range of experts (n=65) and a consumer survey (n=233) were conducted to analyze the feasibility and potential effectiveness of the approach. Responses indicated that a comprehensive sustainability label could considerably influence consumption patterns and facilitate cross-product comparisons.
近期，有机、公平贸易、本地生产以及健康食品的标准和标签激增，这有可能在消费者中造成困惑。本研究提出了一种标准化方法，用于制定一个综合的可持续性标签，该标签纳入了生态、经济和社会价值。该方法基于将模块化生命周期评估扩展到非环境可持续性标准。我们进行了与广泛的专家访谈（n = 65）和消费者调查（n = 233），以分析该方法的可行性和潜在有效性。结果表明，一个综合的可持续性标签可能会极大地影响消费模式并促进跨产品比较。
