Post Carbon Fellow Bill McKibben is one of the climate activists being targeted the conservative group America Rising Squared.

From the article:

A Republican opposition research group is launching an effort to track environmental organizations — and it’s being led by Brian Rogers, a former McCain spokesman who once worked for one.

Rogers is now the executive director of America Rising Squared, the 501(c)(4) branch of the America Rising political action committee. The group announced on Friday that it would be deploying “trackers” to follow billionaire Democratic donor Tom Steyer, environmental writer and activist Bill McKibben and “other key players in the Environmentalist Left.” Trackers are most often deployed in political contests, with campaigns sending a dedicated staffer to follow opponents with a video camera in hopes they say something compromising.
