The representative survey studies provide a comprehensive database on the public awareness and perception of CCS in six selected European countries. Our results provide insights into the public understanding and knowledge of energy related issues and CCS topics. The embedded experimental research provides insights into how information affects CCS perceptions. The results discuss implications for CCS communication methods.
The results presented in this article illustrate how the local public was informed on specific Carbon Capture and Storage (CCS) projects by regional newspapers in Germany. The analyzed articles were published in four daily newspapers within the German regions where four CO2 onshore storage projects took place or have been planned. The articles were published between 2007 and 2011. In total, 1,115 newspaper articles about the four CO2 onshore storage projects were gathered and analyzed both qualitatively and quantitatively. Our results showed that the regional media coverage of CCS projects in Germany reached peaks in 2009 and 2010. The main topics changed within the media coverage and it is worth mentioning to what extent the media coverage of CCS disregarded topics with regard to economic, technical, ecological or scientific aspects on CCS. The overall evaluation of CCS within the articles is negative. While commercial CCS projects received more negative evaluation across newspaper articles; opinions about the research and industry project Ketzin were more neutral.
The present study investigates and compares the public perception of CO2 offshore storage, CO2 onshore storage and CO2 transport via pipeline in Germany nationwide and in two coastal regions. For this purpose, three representative surveys were carried out and analyzed with the methods of descriptive statistics and ordinal regressions. The results of our descriptive statistical analyses show clear regional differences with regard to self-reported awareness, factual knowledge, risk perceptions and general attitudes towards CO2 offshore/onshore storage and CO2 transport via pipeline. With regard to the public perception of the two storage options - offshore and onshore - no major differences could be identified: both are hardly accepted by the German public. In comparison to CO2 offshore storage/CO2 onshore storage, the attitudes towards CO2 transport via pipeline were perceptibly more positive in all regions. Our regression analyses revealed that the perceptions of the personal and societal risks of CO2 transport via pipeline/CO2 offshore storage/CO2 onshore storage as well as the perceptions of the personal and societal benefits of CCS are the most important direct determinants of general attitudes towards CO2 transport via pipeline, CO2 offshore storage and CO2 onshore storage.
Technologien zur Abscheidung und Speicherung von CO2 (CCS) sind eine mögliche Option zur Reduzierung von Treibhausgasen. Ob das Potenzial von CCS als Klimaschutzoption in Deutschland zukünftig genutzt werden wird, hängt aber insbesondere davon ab, ob die Technologien in der Bevölkerung generell und vor Ort akzeptiert werden. Die vorliegende Veröffentlichung gibt einen Einblick in relevante Forschungsansätze und Ergebnisse wissenschaftlicher Untersuchungen zur Akzeptanz von CCS in Deutschland. Sie präsentiert zugleich die Ergebnisse eines Workshops am Wuppertal Institut und vermittelt einen Eindruck von den Herausforderungen bei der praktischen Umsetzung von Forschungsergebnissen und der Durchführung zukünftiger Forschung zur Technikakzeptanz.
