Barriers and limitations for the large-scale deployment of CCS are discussed. CCS and different technological solutions for emission reduction （e.g., energy conservation and renewable energy） are compared. The analysis shows that China should carefully evaluate the negative impacts of CCS deployment and needs to enhance the research and development input in CCS in order to master core technologies of CCS systems. Furthermore, CCS incentives should depend on actual CCS development. Based on the current situation, China may need to focus on retrofitting existing thermal power plants with CCS technology, so CCS can be promoted for future large-scale application.展开更多

Japan＇s GHG （greenhouse Gas） emissions are declining while Brazil＇s are increasing. Among ESTs （environmentally sound technologies） the potential of GHG mitigation of CCS has gained prominence. The research identifies the main activities and positions of the actors involved in CCS technology implementation in Japan and Brazil, and contrasts and compares reasons for the large-scale use of the CCS technologies in the two countries. This analysis is based on a literature review and a field survey done to collect primary data via visits to organizations and experts. This data was enhanced by an analysis of patent deposits in the area of CCS in the two countries in last 20 years. As regards the legal framework for climate change, and for CCS in particular, while responses to the main international decisions can be found in Japan, in Brazil this is not the case. In Japan the public sector has an effective participation together with private sector and civil society. In Brazil CCS activities are conducted by the private sector which is in turn putting pressure on civil society in particular academia. Currently, Japan is focusing on CCS capture technologies, while Brazil is focusing on CCS storage technologies. In summary, the CCS framework is being more efficiently carried out in Japan than in Brazil.展开更多
