In the last few years there has been a surge in interest in the geologic sequestration of carbon dioxide (CO2), a process often referred to as carbon capture and storage, or sequestration (CCS), as a way to mitigate man-made CO2 emissions and thereby help address climate change concerns. The Energy Independence and Security Act contains measures to promote research and development of CCS technology, to assess sequestration capacity, and to clarify the framework for issuance of CO2 pipeline rights-of-way on public land. Other legislative proposals have also sought to encourage the development of CO2 sequestration, capture, and transportation technology. This book discusses the concept and legal issues related to geologic carbon sequestration and mitigation technologies.
