Only sometimes do environmental protests that begin as not-in-my-backyard (NIMBY) objections to proposed facilities become translated into more universal not-in-anyone's-backyard (NIABY) mobilizations. An examination of opposition to liquefied natural gas (LNG) receiving terminals in the United States shows evidence of regional mobilization in the Gulf and West Coasts, but not in the Northeast. Opposition to LNG facilities in the United States thus provides an opportunity to study often overlooked regional mobilization. A narrative of events in each region is provided, with special attention to the key mechanisms of frame bridging, relational diffusion, brokerage and certification. In the case of the Northeast, two contextual factors also appear to have impeded the development of more coordinated opposition to LNG.
