Environmental activists threw orange paint over an outdoor sculpture by American artist Charles Ray in central Paris on Friday, the latest in a series of artworks aimed at spurring greater government efforts to tackle climate change.

The life-size “Horse and Rider” stands in front of the Bourse de Commerce contemporary art museum, which houses part of the collection of French fashion billionaire Francois Pinault.

The action was claimed by Derniere Renovation (“Last Renewal”), which on its website showed two activists kneeling and holding hands in front of the doused sculpture.

They also had a white T-Shift draped over the driver that read “We’ve got 858 days left,” apparently a reference to studies saying carbon emissions must peak by 2025 if the planet has a livable future target.

“Eco-vandalism is taking a stage,” Culture Minister Rima Abdel Malak, who visited the site while workers were removing the paint, wrote on Twitter.

“Art and ecology are not incompatible. On the contrary, they are common causes,” she said.

The incident came as climate activists targeted an Andy Warhol work in Milan on Friday and covered a car repainted by the American pop artist in flour – two weeks after the same group threw pea soup at a Van Gogh painting in Rome.

Vermeer’s Girl with a Pearl Earring in The Hague and Van Gogh’s Sunflowers in London were also targeted, with officials widely condemning them.
