The CCS Policy Indicator (CCS-PI) tracks government policy to accelerate the deployment of carbon capture and storage (CCS) as a climate mitigation technology in over 100 countries. The CCS-PI considers policy across nine measures and applies a quantitative methodology to derive a single score, normalized to 100, for each country. The final score represents the extent to which policy settings support a business case for investment in CCS. Higher scores indicate more developed policy environments. The 2018 assessment shows progress has been made since 2015, with nations including Norway, Japan, China, France, and Mexico achieving a significant increase in their CCS-PI score. The United Kingdom and United States of America saw a reduction in their CCS-PI scores compared to 2015, but both have taken significant and positive steps in 2017/2018. The highest CCS-PI score achieved was 56/100 (Norway).
