Editor & Publisher has details on InsideClimate News and the “ambitious, in-depth investigative series that began as a fluke,” winning the tiny nonprofit organization the 2013 Pulitzer Prize for National Reporting.

The online-only service, which publishes its work under a Creative Commons license, beat out some of the biggest U.S. newspapers to win the honor for its three-part investigative series “The Dilbit Disaster: Inside the Biggest Oil Spill You’ve Never Heard Of.” The series focused on a 2010 crisis caused by a ruptured oil pipeline that spilled at least 1 million gallons into Michigan’s Talmadge Creek and Kalamazoo River, forcing 150 families permanently from their home.

The watchdog organization has a staff of only seven full-timers who work virtually in offices and homes around the country. It’s funded entirely by donations, a similar model to ProPublica, the nonprofit investigative reporting service launched in 2007 that has won two Pulitzers.

The E&P also documents the resourcefulness and determination that enabled the service to bring this story home despite a tiny budget and far-flung staff. The visibility of its work was helped by the fact that media coverage of climate change has declined steadily since 2009, according to E&P.
