Abstract Access to high-quality, timely and comparable data is a prerequisite for any effective decision-making process and having such data available for the environment is absolutely fundamental to efficient and evidence-based policymaking. This article reviews the establishment of a Shared Environmental Information System (SEIS) in Europe and Central Asia to improve our understanding of how environmental data value chains are being employed to produce, share and use reliable data on the environment and whether this data is used in policymaking. Three sources of data are utilised to analyse whether relevant environmental data and information are being drawn upon by policymakers, namely, the 2019 SEIS mid-term review, SEIS Factsheets and SEIS Gap Analysis Reports. The results reveal that the pan-European region still faces significant data harmonisation problems, owing in part to differences in types and methods of data collection, data definitions and legislation. Whilst problems in some individual country’s participation have persisted since the launch of the SEIS initiative in the pan-European region, the development and successful piloting of the SEIS self-assessment framework is considered as evidence of positive progress. However, it remains difficult to adequately assess to what extent the data flows covered by this study impact on policymaking, nevertheless, the analysis serves to highlight the inter-linkages between environmental data flows, policymakers and environmental governance. In practical terms, the paper demonstrate a disconnect between data production and data use in policymaking and emphasises the need to both improve our understanding of the political determinants of data use and to further investigate how the uptake of environmental data and information can be facilitated in policymaking.

分享真的是关怀吗？欧洲和中亚的环境数据价值链和政策制定

摘要 获取高质量、及时和可比较的数据是任何有效决策过程的先决条件，拥有此类环境数据对于高效和循证决策绝对是基础。本文回顾了欧洲和中亚共享环境信息系统 (SEIS) 的建立，以提高我们对如何利用环境数据价值链来生产、共享和使用可靠的环境数据以及这些数据是否用于政策制定。三个数据来源用于分析政策制定者是否正在利用相关的环境数据和信息，即 2019 年 SEIS 中期审查、SEIS 情况说明书和 SEIS 差距分析报告。结果表明，泛欧地区仍然面临着严重的数据统一问题，部分原因是数据收集的类型和方法、数据定义和立法存在差异。虽然自 SEIS 倡议在泛欧地区启动以来，一些个别国家的参与问题一直存在，但 SEIS 自我评估框架的开发和成功试点被认为是积极进展的证据。然而，仍然难以充分评估本研究涵盖的数据流对政策制定的影响程度，不过，该分析有助于强调环境数据流、政策制定者和环境治理之间的相互联系。在实践中，
