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

Since a greenhouse needs huge construction expenses and high production costs, only though the improvement of facility utilization can we obtain better economic benefits. Vegetable germination and seedling stage need a long time for ground, so they need smaller standing area. So we concentrated in a small area of cultivation can not only create a suitable environment easily, nurture strong age seedling, but also can avoid greenhouse waste. Make transplanting to greenhouse after Seedlings breeding can effectively reduce the fertility cycle and substantially increase greenhouse utilization.展开更多
