Official data are not sufficient for monitoring the United Nations Sustainable Development Goals (SDGs): they do not reach remote locations or marginalized populations and can be manipulated by governments. Citizen science data (CSD), defined as data that citizens voluntarily gather by employing a wide range of technologies and methodologies, could help to tackle these problems and ultimately improve SDG monitoring. However, the link between CSD and the SDGs is still understudied. This article aims to develop an empirical understanding of the CSD-SDG link by focusing on the perspective of projects which employ CSD. Specifically, the article presents primary and secondary qualitative data collected on 30 of these projects and an explorative comparative case study analysis. It finds that projects which use CSD recognize that the SDGs can provide a valuable framework and legitimacy, as well as attract funding, visibility, and partnerships. But, at the same time, the article reveals that these projects also encounter several barriers with respect to the SDGs: a widespread lack of knowledge of the goals, combined with frustration and political resistance towards the UN, may deter these projects from contributing their data to the SDG monitoring apparatus.

官方数据不足以监测联合国可持续发展目标 (SDG)：它们不会到达偏远地区或边缘化人群，并且可以被政府操纵。公民科学数据 (CSD) 被定义为公民通过采用广泛的技术和方法自愿收集的数据，可以帮助解决这些问题并最终改善可持续发展目标的监测。然而，CSD 与可持续发展目标之间的联系仍未得到充分研究。本文旨在通过关注采用 CSD 的项目的视角，对 CSD-SDG 链接进行实证理解。具体来说，本文介绍了在其中 30 个项目中收集的主要和次要定性数据以及探索性比较案例研究分析。它发现使用 CSD 的项目认识到可持续发展目标可以提供有价值的框架和合法性，并吸引资金、知名度和伙伴关系。但是，与此同时，文章揭示了这些项目在可持续发展目标方面也遇到了一些障碍：普遍缺乏对目标的了解，加上对联合国的挫败感和政治阻力，可能会阻止这些项目提供数据到 SDG 监测设备。
