In an age of overtourism and overconsumption, eco-minded Casita Verde is changing the tide in Ibiza. Allison Yates visits Chris Dews, the man who’s always been ahead of the curve when it comes to sustainable tourism on the party island.

The road to Casita Verde cuts through fields of carob trees and flat stone structures. It has two lanes, but feels like half of one. Another path bordered by pines and dried brush guides us to the yellow ‘Welcome’ sign. The green letters spelling ‘Casita Verde’ (‘little green house’ in Spanish) seem to wave as you saunter through a tunnel walkway of precisely placed palms, aloes and cacti—seemingly overgrown yet purposefully placed.

We’re on the Spanish island of Ibiza—or Eivissa, as it’s known in Eivssenc, the Catalan dialect of locals—the third largest of the Balearic Islands. You might know it as the pill-popping, yacht-hopping, dance-all-night electronic music hub. Just 150 kilometers off the coast from Valencia, Ibiza transformed throughout the 20th century from a traditional agrarian culture to one witnessing millions of thrill-seeking tourists each year.

But before recycling was cool and sustainable tourism became a buzzword, Casita Verde’s founder, a British expat named Chris Dews, had already re-imagined the island.
