Tiffany and Donald Trump have a longstanding relationship. Reportedly the inspiration behind the name of his second daughter, Trump also bought the air rights (property interest in space above ground level) for the store on Fifth Avenue for $5 billion in order for him to be able to build Trump Tower. However, the relationship has hit turbulence this week after the jewellery brand questioned the president’s stance on climate change.

After recent reports of Trump removing the US from the Paris Climate Agreement, Tiffany Instagrammed a post that urged him to “Please keep the US in the Paris Climate Agreement. The disaster of climate change is too real.” Its advertising spot in Tuesday’s issue of the New York Times was used to further promote the same message and was emphasised by others including Apple and Facebook who signed an agreement that ran as a full-page advert in Monday’s issue

Talking to fashion director and chief fashion critic of the New York Times Vanessa Friedman at the Copenhagen Fashion Summit, the world’s largest event for sustainability in fashion currently being held in Denmark, CEO Michael J. Kowalski wanted to address those who were quick to tell the brand not to get involved in political matters. “This isn’t politics, this is science. If any government or your government begins to deny the unequivocal science of climate change... you have no option but to speak up and to act.”

Kowalski said there’d been no response on Twitter as of yet but with the President a frequent client of the brand, and an even more frequent tweeter, it may only be a matter of time.
