At i-dest.com, we evaluate sustainable tourism using a transparent methodology aligned with international principles. Our assessment framework is based on the criteria of the Global Sustainable Tourism Council (GSTC), which examine environmental, social, economic, and governance aspects, fully aligned with the UN Sustainable Development Goals (SDGs). Alongside quantitative and visual metrics, we provide clear text explanations for every destination, attraction, and service provider, detailing specific local sustainability actions—from nature conservation to responsible operations—while offering practical guidance to help visitors make conscious, eco-friendly travel choices.

To ensure credibility, we strictly verify sustainability claims: our platforms highlight partners whose operations we know firsthand, supporting data reliability through editorial mystery shopping and periodic audits. The presence of editorial verification is clearly indicated in every case, whereas the respective service provider or destination remains responsible for unverified data. For inspiration, we also feature independent best practices from non-partner locations; these are transparently marked as "Editorial Content," and we do not publish unverified quantitative data for them.
