UNWTO has issued a press release release today assuming on the one hand - on behalf of Tourism - a 5% responsibility of global carbon emissions and on the other "cautioning" against 'mitigation' measures for air passenger transport 'taken in isolation' so as 'not to harm' developing countries and 'small island developing states' dependent on tourism.
Hostage to its powerful membership, as the only UN body with multinationals as voting members, UNWTO fails to evaluate what sort of 'development' path the current capitalist tourism model offers to these states,  any "development" will do...(similar to "tourism creates jobs" or the "we employ locals").

But it seems small island states are also being used as hostages by the powerful airline lobby, so that the oligopoly of airlines and aircraft manufacturers can avoid green taxes in perpetuity. The rest of us can happily pay VAT and subsidise new airports, fuel etc.
