Teen environmental activist Greta Thunberg is chalking up a sexually graphic decal of her to climate change skeptics who are “desperate.”

The drawing, originally found on a sticker, shows a naked woman from the back — “Greta” — with a man’s hands pulling on her braids. Also on the sticker is the logo of X-Site Energy Services, an oilfield company based in Alberta, Canada.

“They are starting to get more and more desperate…” Thunberg, 17, tweeted Saturday. “This shows that we’re winning.”

An online petition calling for the company’s executives to resign and issue a public apology had 2,628 signatures by Saturday afternoon.

X-Site’s general manager, Doug Sparrow, claimed the company had nothing to do with the decal. “It’s not from X-Site or any employee, someone has done this. That’s all I know,” Sparrow said, CityNews reported.

Alberta resident Michelle Narang flagged the sticker this week. She received an image of the sticker from a friend in the oil industry, who told HuffPost Canada that sticker was handed out at job sites.

Cops in Red Deer, the town where X-Site has its headquarters, called the sticker “distasteful” on Twitter, but later determined the drawing wasn’t child pornography and couldn’t be considered a criminal offense.

Canada’s minister of culture, Lela Sharon Aheer, slammed the sticker as “deplorable.”

“The graphic in this article is completely deplorable, unacceptable and degrading,” Aheer tweeted. “This is not what our province stands for. Whoever is responsible should be ashamed and apologize immediately.”
