Carbon capture and storage is promoted as a mitigation method counteracting the increase of atmospheric CO 2  levels. However, at this stage, environmental consequences of potential CO 2  leakage from sub-seabed storage sites are still largely unknown. In a 3-month-long mesocosm experiment, this study assessed the impact of elevated  p CO 2  levels (1,500 to 24,400 μatm) on  Cerastoderma edule  dominated benthic communities from the Baltic Sea. Mortality of  C. edule  was significantly increased in the highest treatment (24,400 μatm) and exceeded 50%. Furthermore, mortality of small size classes (0–1 cm) was significantly increased in treatment levels ≥6,600 μatm. First signs of external shell dissolution became visible at ≥1,500 μatm, holes were observed at >6,600 μatm.  C. edule  body condition decreased significantly at all treatment levels (1,500–24,400 μatm). Dominant meiofauna taxa remained unaffected in abundance. Densities of calcifying meiofauna taxa (i.e. Gastropoda and Ostracoda) decreased in high CO 2  treatments (>6,600 μatm), while the non - calcifying Gastrotricha significantly increased in abundance at 24,400 μatm. In addition, microbial community composition was altered at the highest  p CO 2  level. We conclude that strong CO 2  leakage can alter benthic infauna community composition at multiple trophic levels, likely due to high mortality of the dominant macrofauna species  C. edule .
