Eiffel Tower lights up with messages of hope on the eve of COP21 Climate Conference

- 29 Novembre 2015

PARIS (NOVEMBER 29, 2015) The night before the long-awaited COP21 negotiations in Paris, and the day over 2000 climate marches took place around the world, artistic messages advocating climate change solutions lit up the famous Eiffel Tower in Paris. 

Created by artist Naziha Mestaoui, the series of inspiring images called for a shift to 100% renewable energy and the protection of the world’s forests, and were projected onto the full facade of the Eiffel Tower, Paris’s most iconic landmark that has recently transitioned to be powered by 100% renewable energy. The installation, “1 Heart 1 Tree”, aims to engage citizens and to help drive an ambitious global deal at COP21. Following the November 13 attacks in Paris, the artist also incorporated messages of unity and hope, and the hashtag #NousSommesUnis. 

The projection was launched at an event next to the Eiffel Tower on Sunday night featuring speeches from UN Secretary General Ban Ki-moon, celebrity ambassador Marion Cotillard and the artist Naziha Mestaoui. 

“I created this installation so that people everywhere can realise what is possible if we come together,” said Mestaoui. “We can protect and regrow our forests, we can tap the natural powers of the sun, the wind, the earth and the sea, and we can build a safer future if we go 100% clean energy for everyone.”

United Nations Secretary General, Ban Ki-moon, commented, “as Secretary General of the United Nations, I am telling you that you should raise your voices and make your leaders accountable to their promises. We have to make the world better for all.”

Nicolas Hulot, Special correspondent for the French President for the Environment, touched on the recent terrorist attacks in Paris, saying “this work reminds us that in a forest we hear the trees that fall, but we don’t hear the 1000 saplings grow. In cities, we hear the ten idiots who kill, but we don’t hear the millions that love.”

Academy Award-winning actress Marion Cotillard, ambassador for and long-standing supporter of “1 Heart 1 Tree”, acted as MC for the evening. She said of the project, “I found this artistic, citizen project very inspiring because our climate is in a state of emergency, and this is why we’re all here tonight.”

Global campaigning organization Avaaz joined the event to represent over 3.6 million people who have signed a petition calling for a 100% clean energy world. Executive Director Ricken Patel said: "From millions of people in the streets, to leaders in summit rooms, to experts from all disciplines, everyone is calling for one clear answer, the only answer, to climate change: a transition to 100% clean energy. Paris must commit to it."
