Medical tourism and sustainable development concerns how travel for treatment relates to the United Nations Sustainable Development Goals and to the environmental cost of travel. The framework contains no target or indicator addressing medical travel, health tourism or cross-border care, so the subject is approached through targets that bear on it indirectly and through evidence about tourism in general.
The relevant targets
Goal 3 is to ensure healthy lives and promote well-being for all at all ages.[1] Two of its targets are engaged by arguments about medical travel. Target 3.8 is to achieve universal health coverage, including financial risk protection, access to quality essential health-care services and access to safe, effective, quality and affordable essential medicines and vaccines for all.[1] Target 3.c is to substantially increase health financing and the recruitment, development, training and retention of the health workforce in developing countries, especially in least developed countries and small island developing States.[1]
Target 3.c is measured by indicator 3.c.1, health worker density and distribution, for which the World Health Organization is the custodian agency.[2] That indicator is the closest point of contact between the goal framework and the workforce arguments made about medical travel, but it measures density and distribution rather than movement between sectors, and the framework attributes no such movement to medical travel.
The environmental dimension
Travel for treatment is travel, and its environmental cost has not been measured separately from tourism as a whole. For tourism generally, a study by Lenzen and colleagues put tourism’s global carbon footprint at 4.5 gigatonnes of carbon dioxide equivalent in 2013, about 8 per cent of global greenhouse gas emissions, and four times an earlier estimate.[3]
One figure from that paper is frequently quoted in a form the authors withdrew. The published correction records that air travel’s contribution to tourism’s carbon footprint was originally given as 20 per cent, or 0.9 gigatonnes, and that the corrected figures are 12 per cent and 0.55 gigatonnes.[4] The higher figure continues to circulate and should not be used.
A separate exercise by the World Tourism Organization and the International Transport Forum modelled transport-related emissions of the tourism sector and projected that they would amount to 5.3 per cent of forecast man-made emissions by 2030.[5] That study and the Lenzen paper measure different things, tourism transport in one case and the whole tourism footprint in the other, and their percentages are not alternative estimates of the same quantity. The copies of the modelling report available on 30 September 2026 were third-party mirrors rather than the publisher’s own, and sources differ on its figure for tourism transport as a share of all transport emissions, so only the figure on which they agree is given here.
Related terms
Sustainable tourism is the wider field in which the environmental arguments sit. Universal health coverage is the target most often cited in the health direction, and health workforce retention the one most often cited against medical travel in developing countries.
No figure attributing any share of tourism emissions to travel undertaken for treatment was identified, and this entry states none. Applying a tourism-wide percentage to medical travel would assume a pattern of journeys and distances that no source establishes.

Sourcing note: the Sustainable Development Goal targets, the indicator metadata and the published correction to the Lenzen paper were opened and read on 30 September 2026. The modelling report by the World Tourism Organization and the International Transport Forum could not be retrieved from the publisher’s own site on that date, which returned access errors, so its figure is reported from a third-party copy and is labelled accordingly; the figure on which available copies disagree has been left out. No source attributes any quantity of emissions specifically to travel for treatment, and none is asserted here.
