…A couple of long-term scenario runs reveal that GTTM-dyn compares reasonably with projections found in the literature. The same scenario runs also show that tourism is not likely to be able to reduce its carbon dioxide emissions without very strong policy interventions. Even in the unlikely lowest growth scenario, total transport increases by a factor of 3.6, requiring technological solutions to reduce emission factors for transport of more than 70% to just keep emissions at current levels…
