Many empirical studies have found an association between sustainable consumption and well-being. However, the direction of causality between these constructs remains unclear. Well-being could be an antecedent of sustainable consumption or, sustainable consumption a driver of well-being; also, there could be a reciprocal relationship between these two constructs. Alternatively, both well-being and sustainable consumption could be outcomes of another construct that could be masking a relationship between well-being and sustainable consumption. This study aims to advance the well-being and sustainable consumption research by testing these three relationships in a longitudinal study with young consumers (n = 369). The findings show that when controlling for the constructs at Time 1, the relationship between the focal constructs is no longer significant. Results lead to support the hypothesis that sustainable consumption and well-being are explained by a particular trait of the individual, nature relatedness, so that individuals with greater nature relatedness are more likely to adopt a sustainable lifestyle and have greater well-being. Nature relatedness thus acts as a predictor of both focal constructs. This result implies that by nurturing nature relatedness, societies will achieve the double dividend of well-being and sustainability.

许多实证研究都发现可持续消费与福祉之间存在关联。但是，这些构造之间因果关系的方向仍然不清楚。福祉可能是可持续消费的先决条件，或者，可持续消费是福祉的驱动力；同样，这两个结构之间可能存在对等关系。另外，福祉和可持续消费都可能是另一种可能掩盖福祉与可持续消费之间关系的结构的结果。本研究旨在通过与年轻消费者（n = 369）。研究结果表明，在控制时间1的构建体时，焦点构建体之间的关系不再重要。结果导致支持这样的假说，即可持续消费和福祉是由个人的特定特征即自然相关性来解释的，因此，具有更大自然相关性的个人更有可能采取可持续的生活方式并拥有更大的福祉。因此，自然相关性可以作为两个焦点结构的预测因子。这一结果表明，通过培养与自然的联系，社会将实现福祉和可持续性的双重红利。
