IEA Greenhouse Gas R&D Programme

Meeting the long-term goal of the United Nations Framework Convention on Climate Change (UNFCCC) to limit global temperature rises to 2°C will require radical changes to energy systems over the coming decades. In this context, carbon capture and storage (CCS) represents a key mitigation option to achieve the envisaged emission reduction pathways in a cost efficient manner. Furthermore, CCS is currently the only technology that can enable deep cuts in CO2 emissions, or even “negative” emissions, across fossil-based power generation and many carbon intensive industries.
This study aims to characterise key countries and regions worldwide where CCS could play an important part of mitigation efforts, based on national circumstances and priorities. Given the need to reach an international climate agreement at the 21st Conference of the Parties (COP21) in December this year in Paris, the study provides a basis for understanding the relevance of CCS within this process. The study also looks at how CCS deployment barriers can be addressed and needs met, and identifies how CCS can be supported through international frameworks.
