This study explores the relationship between Carbon Capture, Utilization, and Storage (CCUS) capability and carbon emissions in the United States, using thirteen predictors. The research employs various econometric techniques, including OLS, Lasso, Ridge, Elastic Net, Generalized Method of Moments, and Seemingly Unrelated Regression. The Elastic Net model outperforms others in explaining CCUS capacity, while OLS is effective for carbon emissions. Key findings include positive impacts of project numbers and foreign direct investment on CCUS capacity, but limited influence from technology level. The relationship between CCUS capacity and carbon emissions remains weak. The study highlights the importance of incentivizing projects to enhance CCUS capabilities and the critical role of legal and regulatory frameworks in facilitating effective CCUS implementation. It also emphasizes that achieving decarbonization goals requires developing affordable green alternatives and viewing CCUS as a complementary solution to emission reduction efforts.This study explores the relationship between Carbon Capture, Utilization, and Storage (CCUS) capability and carbon emissions in the United States, using thirteen predictors.
