EXPLORATION OF PUBLIC ACCEPTANCE REGARDING CO_2 UNDERGROUND SEQUESTRATION TECHNOLOGIES

摘要

We have investigated the mechanisms of gaining public acceptance through questionnaires and focus group interviews as part of a project to develop the CO_2 aquifer sequestration technology being promoted by RITE. We acquired valuable knowledge although we could not verify certain attributes with a reasonable degree of certainty and our sample size was small. The results of our investigation have indicated that the public's concerns regarding the global warming issue are fairly modest and few respondents oppose the development of CO_2 aquifer sequestration technology. However, about half of the respondents felt it is too early to decide whether such technology should be put into practical use. Respondents had many questions concerning the effects of CO_2 leakage on the local environment, the reasons for choosing this technology, and the capacity of aquifers, and also expressed anxiety and doubt regarding the promoter or the technologies. About half of the respondents regarded the process through which mutual agreement is reached as important. We found that focus group interviews are a valuable complement to quantitative research done through questionnaires and may also be useful for deepening understanding or visualizing the process by which mutual agreement can be reached. Mutual confidence and sincere communication are essential to persuade local residents of the need to implement such a technology in their area.
