Carbon capture and storage (CCS) is a technology designed to reduce greenhouse gas emissions by capturing CO₂ from industrial processes or power generation and securely storing it in geological formations. Băile Lăzărești serves as a promising natural laboratory for studying the environmental effects of potential CO₂ leakage from an anthropogenic CO₂ storage site and for testing monitoring solutions. One effective method for environmental monitoring of CO₂ geological storage involves soil flux and soil gas surveys, which can identify potential CO₂ leakage points by determining the natural variability of CO₂ flux. Since 2019, several soil flux surveys have been conducted at Băile Lăzărești across different seasons, combined with soil-gas measurements. By analyzing seasonal CO₂ variation along with geological knowledge, we have determined the natural variability of post-volcanic emissions and important for monitoring CO₂ geological storage sites, aiding in the identification and understanding of potential leakage in the near-surface environment.
