CO2 Storage and Emission Strategies

In 2019, global CO2 emissions reached 33 billion metric tons, contributing to climate change. To meet climate targets, we must achieve zero emissions in 30 years, which is impossible without carbon capture and storage (CCS) technologies. CCS involves injecting CO2 deep underground, where it is securely stored in geologic formations. The US has significant potential for CO2 storage, which could support economic growth and job creation. Implementing federal policies and investing in zero-carbon solutions are crucial for reaching climate goals and building a robust carbon management economy.
