#’Climate mayor’ bankrolled by dad with massive carbon footprint

Former Obama housing secretary Shaun Donovan says he’d be “the climate mayor,” but his multimillionaire dad, who’s funding his long-shot City Hall bid, is the opposite of an environmental steward.

Michael Donovan — who has given $6.8 million through a super PAC, making him the single largest donor in the entire mayoral race — owns three homes, a gas-guzzling private jet, and once destroyed wetlands in front of his $18 million Bridgehampton estate.

“If candidates are taking money from polluters, they are making a big mistake because people suffer,” said Maritza Silva-Farrell, head of the New York umbrella environmental group ALIGN.

Michael Donovan, 80, pioneered advertising software and had a near-monopoly of the media billing and tracking industry until his firm Donovan Data Systems merged with another company called Mediabank in 2011, forming a third entity called Mediaocean.

“Every major ad agency in the world uses their software,” a business colleague told The Post.

The tech entrepreneur remains on Mediaocean’s board. Google is now a major competitor.

The merger was approved by President Barack Obama’s Department of Justice when Shaun Donavan was a member of the cabinet.

“His father stood to gain hundreds of millions of dollars from something that the DOJ was reviewing,” the business colleague said.

“Everything was aboveboard, but it had potential to be very awkward,” he said.

Mediaocean was acquired by Vista Equity Partners in a $720 million deal in 2015. A year later, Michael Donovan landed on the Real Deal’s list of top Hamptons residential sales with his $18.2 purchase of 411 Jobs Lane in Bridgehampton. The 11,550-square-foot contemporary home has 11 bedrooms, 12-and-a-half bathrooms and a five-car garage.

Michael Donovan’s Manhattan address is just as impressive. He lives at 1040 Fifth Ave., a limestone luxury cooperative building that was once home to Jacqueline Kennedy Onassis.

He has a “very nice plane to fly his family back and forth” to a third home in Charlottesville, Va., the business colleague told The Post, adding that the private jet was recently upgraded from a Cessna Citation.

In February 2017, a year after he bought the Long Island mansion, the Southhampton Planning Department hit Michael Donovan with a citation for mowing through a 75-foot-wide “naturally vegetative wetland” in front of his home, according to Martin Shea, the town’s chief environmental analyst.

“Some significant clearing had occurred within the restricted buffer zone,” Shea told The Post. “He was required to discontinue all disturbance in that area and allow that area to come back,” Shea said.

“Wetlands are exceptionally important in terms of surface water quality, in terms of wildlife habitat,” Shea said.

Curtis Sliwa, the Guardian Angels founder and Republican mayoral candidate, called Shaun Donovan a hypocrite for benefiting from his dad’s money while claiming to care about the environment.

“It’s so typical of so many people running for office, it’s ‘Do as I say, not as I do,’ or ‘as my main benefactor, my father, has done,’” Sliwa said.

“If he wants that title, of being, you know, the next green mayor, the one that’s going to maintain our ecology, he’s going to have to denounce his dad. He’s taking money that obviously was used for reverse,” Sliwa said.

Despite the millions Michael Donovan has spent on ads supporting his son, Shaun Donovan has been polling in the single digits.

Neither Donovan responded to requests for comment.
