Now this is not a marketing gimmick. In 2016 Slovenia was officially declared by the Netherlands-based organisation Green Destinations as the world's first green destination. That same year, the capital city Ljubljana held the title of European Green Capital. Two years prior, Slovenia made it into the list of top 100 sustainable tourist destinations. So there can be no doubt that Slovenia is truly green, and remains one of the most pristine, environmentally-friendly and sustainable tourist destinations in the world. Mind you anyone who lives here or has visited Slovenia before, already knows this.
