Abstract

Anthropogenic climate change necessitates urgent implementation of carbon dioxide (CO₂) removal and utilisation strategies. While the CO₂ removal efficiency of such strategies is commonly evaluated, their environmental impacts beyond CO₂ emissions needs consideration to avoid burden shifting. This study performs a life cycle assessment of CO₂ removal and utilisation strategies in ten specific European locations. The study considers strategies such as direct air carbon capture, permanent storage, the production of fuels and polymers. The energy source, CO₂ transport distances, transport mode (pipeline and ship) and the CO₂ storage medium vary between the locations. Results indicate that seven of the ten considered locations have a CO₂ removal efficiency greater than 95%. In addition, the hotspot analysis indicates CO₂ capture and its transport contribute to between 0.3% and 13.1% of global warming impacts of polymer production and between 0.4% and 16.5% for fuel production (varies based on the polymer and fuel type).

二氧化碳清除和利用战略的生命周期评估：欧洲各国的比较分析

人为的气候变化迫切需要实施二氧化碳（CO2）去除和利用战略。虽然此类战略的二氧化碳去除效率通常会得到评估，但需要考虑其二氧化碳排放之外的环境影响，以避免负担转移。本研究对欧洲十个特定地区的二氧化碳去除和利用策略进行了生命周期评估。研究考虑了直接空气碳捕集、永久储存、燃料和聚合物生产等策略。各地的能源、二氧化碳运输距离、运输方式（管道和船舶）以及二氧化碳储存介质各不相同。结果表明，在考虑的 10 个地点中，有 7 个地点的二氧化碳去除效率超过 95%。此外，热点分析表明，二氧化碳捕集及其运输对聚合物生产的全球变暖影响介于 0.3% 和 13.1% 之间，对燃料生产的影响介于 0.4% 和 16.5% 之间（根据聚合物和燃料类型而异）。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
