永續（可持續）旅遊（Sustainable Tourism） 是從永續發展（Sustainable Development）的概念引伸出來的旅遊業發展原則和理念，是永續思想與旅遊業的有機結合，適用於所有能夠在長期發展過程中與自然、社會、文化環境和諧共存與協調發展的旅遊形式。（鍾林生等，2003，生態旅遊規劃原理與方法，北京化學工業出版社，P8-9）
2015年9月聯合國第70屆大會宣布，將2017年訂為「國際永續旅遊發展年」（International Year of Sustainable Tourism for Development），並在2016年5月發表宣傳影片如下：
不知政府對明年這件世界觀光主題活動有無想法或配合措施？
永續旅遊怎麼做？我覺得就參考聯合國於2016年1月1日啟動的永續發展目標議程（2030 Agenda for Sustainable Development）中有17項永續發展目標（Sustainable Development Goals, 簡稱SDGs），依著要達到這些目標而採取的策略與行動應該就是永續旅遊要遵守及實踐的。
請看以下17項永續發展目標：

世界旅遊組織新聞稿如下：
The United Nations (UN) General Assembly has approved the adoption of 2017 as the International Year of Sustainable Tourism for Development. The resolution, adopted on 4 December, recognizes “the importance of international tourism, and particularly of the designation of an international year of sustainable tourism for development, in fostering better understanding among peoples everywhere, in leading to a greater awareness of the rich heritage of various civilizations and in bringing about a better appreciation of the inherent values of different cultures, thereby contributing to the strengthening of peace in the world”.
“The declaration by the UN of 2017 as the International Year of Sustainable Tourism for Development is a unique opportunity to advance the contribution of the tourism sector to the three pillars of sustainability – economic, social and environmental, while raising awareness of the true dimensions of a sector which is often undervalued” said UNWTO Secretary-General, Taleb Rifai. “As the lead UN agency for this initiative, UNWTO is very much looking forward to proceeding with the organization and implementation of the International Year, in collaboration with Governments, relevant organizations of the UN system, other international and regional organizations and all other relevant stakeholders”, he added.
This decision follows the recognition by global leaders at the UN Conference on Sustainable Development (Rio+20) that “well-designed and well-managed tourism” can contribute to the three dimensions of sustainable development, to job creation and to trade.
The decision to adopt 2017 as the International Year of Sustainable Tourism for Development comes at a particularly important moment as the international community embraces the new Agenda 2030 and the Sustainable Development Goals (SDGs), approved by the UN General Assembly last September. Tourism is included as targets under three of the SDGs – SDG 8: Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all; SDG 12: Sustainable Consumption and Production and SDG 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development.
