"We find that, between 2009 and 2013, #tourism’s global #carbon #footprint has increased from 3.9 to 4.5 GtCO2e, four times more than previously estimated, accounting for about 8% of global greenhouse gas #emissions."

"The United States tops the carbon #footprint ranking (Fig. 1,top left) under both DBA (1,060 MtCO2e) and RBA (909 MtCO2e) accounting perspectives, followed by China (528/561 MtCO2e), Germany (305/329 MtCO2e) and India (268/240 MtCO2e)."

"The majority of these carbon #footprints are caused by domestic travel."

"‘net travellers’ such as Canadians, Swiss, Dutch, Danish and Norwegians exert a much higher carbon footprint elsewhere than others in their own country. In contrast, ‘net hosts’ such as islanders and residents of popular tourist destinations..."

... such as Croatia, Greece and Thailand shoulder much higher footprints from their visitors than they exert elsewhere"

"The map of global carbon movements shows that travelling is largely a high-income affair, and as a result carbon embodied in tourism flows mainly between high income countries acting both as traveller residence and destinations (Fig. 3 and Table 1)."

"In the case of #tourism, an annual 7% or 5-year 30% increase in tourism-related expenditure during 2009 2013 has cancelled out all carbon intensity reductions (- 2.7%/-12.9%), and caused the carbon footprint of global tourism to increase by 3.3% annually or 14% over the period"
