Carbon capture and storage (CCS) has the potential to dramatically reduce GHG emissions in energy supply and industry. However, its high costs mean that uncertainty about the stringency of future climate policy may dissuade firms from investing in this technology. This article explores the relationship between firms expectations of government policy and investment in CCS. First, it synthesizes recent cost estimates for CCS applications in electricity generation and oil sands extraction in Canada. Second, it uses these estimates to investigate the potential impact of policy stringency and uncertainty on CCS adoption in Alberta, a Canadian province with near-ideal CCS potential. The results suggest investment in CCS, and by extension other costly abatement actions, will not occur unless governments create a more stringent and durable climate policy environment than currently exists
