最近大气中人为温室气体含量的迅速增加已被确定为一个严重的环境问题，不利于全球经济的可持续发展。为了将大气中温室气体的浓度稳定在可接受的水平，短期内必须采取大幅度的减排措施，同时正在制定长期的非碳基能源选择。二氧化碳地质封存技术是一项有前景的技术，可以快速、大规模地减少排放到大气中的温室气体，技术相对成熟。然而，在考虑二氧化碳封存项目之前，必须完成具体地点的深入技术经济、地质和物理分析，以评估可行性，并确保采取适当措施，监测系统性能，保证公共安全和环境保护。下一节概述地质封存的概念和实施地质封存的重要步骤。
The recent rapid rise of anthropogenic greenhouse gas content in the atmosphere has been identified to be a serious environmental concern and does not support sustainable development for the global economy. Drastic emission reduction measures are necessary in the near term to stabilize the concentration of greenhouse gas in the atmosphere to an acceptable level while longer-term non-carbon based energy options are being developed. Geological sequestration of CO2 is a promising technology which can effect a rapid and large-scale reduction of GHG being emitted into the atmosphere and the technology is relatively mature. However, before considering CO2 sequestration projects, a site specific in-depth techno-economic, geological and physical analysis has to be completed to assess feasibility and ensure appropriate measures are put into place to monitor system performance and guarantee public safety and environmental protection. The following section summarises the concepts of geological sequestration and the important steps to be followed for its implementation.
