The Department of Interior has released a report entitled, “Framework for Geological Carbon Sequestration on Public Land.” The report was completed in compliance with the Energy Independence and Security Act of 2007, and details the issues for sequestering CO2 under public land, which represents 5 percent of the potential sequestration sites in the U.S. The report also delves into regulation, management of storage sites, and the issue of liability. The report lends further weight to the view that issues of liability are unclear and problematic. The report goes as far as to say "the long time horizons involved in geologic sequestration of carbon may require further analysis of appropriate risk and cost-sharing mechanisms." The report, though, does not opine on what adjustments to such mechanisms may be needed, e.g. governmental assumptions of liability, statutes of limitations, liability caps, or other potential liability limiting mechanisms.
