A new law in South Dakota prohibiting the use of eminent domain to acquire land for carbon capture pipelines raises questions about the viability of a proposed 2,500 mile (4,023-kilometer) project snaking through five Midwest states.

South Dakota's governor has signed a bill into law that bans the taking of private property for building carbon dioxide pipelines.

Gov. Larry Rhoden signed South Dakota House Bill 1052 into law Wedneday, prohibiting carbon pipeline companies from using eminent domain.
