In August 2010, the Federal Bureau of Investigation’s Domestic Terrorism Analysis Unit distributed an intelligence bulletin to all field offices warning that environmental extremism would likely become an increasing threat to the energy industry. The eight-page document argued that, even though the industry had encountered only low-level vandalism and trespassing, recent “criminal incidents” suggested that environmental extremism was on the rise. The FBI concluded: “Environmental extremism will become a greater threat to the energy industry owing to our historical understanding that some environmental extremists have progressed from committing low-level crimes against targets to more significant crimes over time in an effort to further the environmental extremism cause.” Since the 2010 FBI assessment was written, the specter of environmental extremism has been trotted out by both law enforcement and energy-industry security teams to describe a wide variety of grassroots gro ups opposed to the continued extraction of fossil fuels. Yet even as the resistance to “extreme energy projects” has grown in size and scope, there is little evidence to support the breathless warnings about “eco-terrorism.” Nevertheless, the FBI, the Department of Homeland Security, and many state law enforcement agencies continue to promote the idea that environmental extremism is on the rise. At the same time, numerous intelligence-sharing networks between the private sector and law enforcement have been established at every level of government, giving rise to an unprecedented energy-intelligence complex.
