https:/crsreports.congress.gov Updated February 21, 2020Carbon Sequestration Legislation in the 116th CongressUtilizing permanent underground storage of carbon dioxide (CO2), also known as geological sequestration, as a potential strategy to reduce net greenhouse gas (GHG) emissions is receiving increasing congressional attention. Proponents of geological sequestration of CO2 view the process as a promising method of reducing GHG emissions from stationary sources, such as coal-fired power plants, while continuing to use fossil fuels as a source of electricity. Several bills introduced in the 116th Congress would address geological sequestration policy issues, focusing on federal research and development (R&D) and federal tax credits for storing carbon. Carbon Sequestration Geological sequestration of CO2, a type of carbon storage, is the process of storing CO2 by injecting it into an underground geological formation.

Geological sequestration is intended to trap CO2 emitted from anthropogenic sources perman
