The Duke of Cambridge appeared in apt attire last night as he announced the first slate of winners of his newly-launched Earthshot Prize celebrating innovations in the ongoing fight against climate change.

The city of Milan was among the five inaugural winners of the prize, which is the brainchild of Prince William and famed British naturalist television presenter Sir David Attenborough. Awards were given out across five separate categories each with a £1 million ($1.37 million) prize. 

The Italian city won in the ‘Build a Waste-Free World’ category for its food waste scheme that can recover around 350 kg of food a day from supermarkets and restaurant venues and redistribute it to the city’s different areas of need. 

Costa Rica took home the inaugural ‘Protect & Restore Nature’ award for a Ministry of Environment program begat in the late 90s that pays citizens to plant trees and eventually help restore the country’s greatest natural resource to twice its atrophied size.

A three-year-old company called Enapter was awarded in the ‘Fix our Climate’ category for their AEM Electrolyser invention which can convert electricity into emission-free hydrogen gas useful in cars, planes, home heating, and a host of other highly pollutant industries. Another startup from India won the ‘Clean our Air’ category for its crop residue converter that can help farmers turn their agricultural waste into profit in lieu of burning it, which can have catastrophic consequences on human health worldwide. The final winner in the ‘Revive our Oceans’ category went to a Bahamas-based company called Coral Vita that regrows coral reefs with vegetation replanted from land-based farms.

“We know where this story is heading, and we know that we must give it a different direction,” Attenborough said of the urgency of the moment at the Sunday night ceremony. “We don’t have eternity. We need to do this now.”
