The phenomenon of anthropogenic climate change has been identified as a threat multiplier for many human-related concerns. Carbon capture and storage (CCS) can, in combination with several other mitigation technologies, alleviate global warming by reducing carbon dioxide (CO2) emissions. Reducing climate change-related risks via CCS creates another risk, smaller in extent: the risk that some of the stored CO2 leaks out of the storage complex. This article reviews European legislation and evaluates how one of its objectives, that private liabilities of CCS-related leakage risks are not socialized, is ensured. Slight modifications of European legislation are suggested in order to prevent an indefinite liability of CCS operators in case a storage complex turns out to be unexpectedly and unavoidably prone to CO2 leakages. Official German and Hungarian financial precaution specifications are contrasted and related to this article’s finding that the state budget is sufficiently hedged against the expected value of climate-related leakage compensation costs of poorly managed storage complexes if 3 to 6% of a CCS operator’s emission-related revenues are diverted into a financial precaution fund.

财务预防措施、二氧化碳泄漏和关于碳捕获和储存 (CCS) 的欧洲指令 2009/31/EC

人为气候变化现象已被确定为许多与人类有关的问题的威胁倍增器。碳捕获和储存 (CCS) 可以与其他几种缓解技术相结合，通过减少二氧化碳 (CO2) 排放来缓解全球变暖。通过 CCS 减少与气候变化相关的风险会产生另一个风险，但程度较小：一些储存的二氧化碳从储存设施中泄漏的风险。本文回顾了欧洲立法并评估了其目标之一，即 CCS 相关泄漏风险的私人责任不会社会化，是如何确保的。建议对欧洲立法稍作修改，以防止 CCS 运营商在存储综合体意外且不可避免地容易发生 CO2 泄漏时承担无限期责任。
