Media can affect public views and opinions on science, policy and risk issues. This is especially true of a controversial emerging technology that is relatively unknown. The study presented here employs a media content analysis of carbon capture and storage (CCS), one potential strategy to reduce greenhouse gas emissions. The authors analyzed all mentions of CCS in two leading Canadian national newspapers and two major western regional newspapers from the first article that discussed CCS in 2004 to the end of 2009 (825 articles). An in-depth content analysis was conducted to examine factors relating to risk from CCS, how the technology was portrayed and if coverage was negatively or positively biased. We conclude by discussing the possible impact of media coverage on support or opposition to CCS adoption.
