In the near future, the use of coal may be legally restricted due to concerns over the effects of its combustion on atmospheric carbon dioxide concentrations. Carbon capture and geologic sequestration offer one method to reduce carbon emissions from coal and other hydrocarbon fuel. While the federal government is providing increased funding for carbon capture and storage, congressional legislative efforts to limit carbon emissions have failed. However, regional and state bodies have taken significant actions both to regulate carbon and to facilitate its capture and storage.
