Carbon capture and storage (CCS) is a critical tool in the global effort to reduce industrial greenhouse gas emissions, and ExxonMobil is at the forefront of advancing this technology at scale. By building a robust CCS infrastructure and prioritizing safety at every stage—from capture to transport to storage—the company is supporting U.S. industries in their journey toward lower carbon operations while protecting the communities where it operates.
ExxonMobil is developing what is considered one of the most advanced CCS networks in the world. This system includes an extensive network of CO₂ pipelines and secure geological storage sites, many of which are located in the U.S. Gulf Coast region. The network is designed to serve major industrial areas, allowing multiple facilities to connect and transport captured CO₂ for safe, permanent storage.
This large-scale approach allows for operational efficiency and the reduction of emissions across entire industrial hubs. It also supports the production of low-carbon products, helping industries remain competitive in a global economy that increasingly favors sustainability.
The question of safety is central to any discussion on CCS. ExxonMobil applies rigorous safety protocols and technical standards throughout the lifecycle of CO₂ capture and storage.

Captured CO₂ is first compressed and then transported through pipelines constructed and operated in compliance with strict engineering standards and regulatory frameworks. These pipelines are equipped with continuous monitoring systems, automated shut-off valves, and regular inspection schedules to detect and address any potential issues before they escalate. Every component of the system is backed by redundancy and real-time monitoring to ensure maximum operational integrity.
Once the CO₂ reaches a designated storage site, it is injected deep underground into carefully selected geological formations. These formations are typically thousands of feet below the Earth’s surface and are capped by impermeable rock layers that prevent the CO₂ from migrating upward.
Before any storage site is approved for use, it undergoes extensive geological surveys, modeling, and risk assessments to confirm its suitability. Continuous monitoring is maintained throughout the storage process, with pressure data and other indicators tracked in real time to verify that the CO₂ remains safely contained.
The company also adheres to federal and state regulatory requirements and works with third-party experts to review and validate its safety systems and environmental protections.
ExxonMobil recognizes that building and maintaining trust with local communities is just as important as technical excellence. The company actively engages with stakeholders in areas where its CCS infrastructure is located, ensuring that residents, civic leaders, and first responders are informed and prepared.
Through public meetings, educational outreach, and collaboration with emergency services, the company provides clear information about how CCS works and what safety measures are in place. Local responders are trained in emergency procedures, although incidents are rare thanks to the robust systems in place.
Carbon capture and storage is widely regarded by climate scientists and energy experts as an essential component of the pathway to net-zero emissions. The International Energy Agency (IEA) projects that CCS could contribute up to 15% of the global emissions reductions required by 2050.
ExxonMobil’s investment in CCS reflects a broader strategy to support a lower-emissions energy future. In addition to providing a practical solution for decarbonizing hard-to-abate sectors such as manufacturing and power generation, the company’s CCS efforts help preserve jobs and support economic resilience in industrial regions.
By combining innovation with a steadfast focus on safety and public engagement, ExxonMobil is setting a high standard for responsible CCS deployment. The work being done today lays the groundwork for a cleaner, safer, and more sustainable tomorrow.
