Mordor Intelligence says the global sustainable tourism market will grow from $3.161 trillion in 2026 to $4.590 trillion by 2031 as travelers and operators shift toward lower-impact, community-connected travel. Europe leads the market today, while Asia-Pacific is expected to grow fastest as certifications, decarbonization efforts and destination management reshape the industry.

Why it matters: - Sustainable tourism is moving from a niche travel preference to a major industry theme as travelers demand lower-impact trips and businesses face more scrutiny over environmental claims. - The shift is changing how destinations, airlines, hotels and tour operators compete, with verified sustainability practices becoming a commercial differentiator. - The market’s projected growth suggests responsible travel is becoming a bigger revenue pool across accommodation, transportation, activities and booking channels.
