A new record of 43.6 million metric tons of carbon dioxide was stored underground in 2024.

The surge in underground storage reflects growing efforts to combat climate change, with nations and corporations increasingly turning to geological sequestration as a means to reduce atmospheric CO₂ levels. This method involves injecting captured CO₂ into deep rock formations where it is trapped permanently, mitigating its greenhouse effect.

In the past three decades, over 421 million metric tons of carbon dioxide have been stored underground, marking significant progress in carbon capture and storage technologies.

Despite these advancements, long-term vulnerability remains as reliance on this technology could divert focus from reducing emissions at source. Additionally, potential leakage risks pose ongoing ecological degradation concerns.

Can local infrastructure withstand future compounding shocks?

The robustness of underground storage facilities is critical for long-term climate mitigation strategies. However, the risk of leaks and the need for continuous monitoring and maintenance present significant challenges. Infrastructure must be resilient to natural disasters and human errors to ensure safety.

Infrastructure resilience remains a key concern.
