Carbon travel tax - who benefits?

KINGSTON, Jamaica - Two United Nations specialist agencies, the International Civil Aviation Authority (ICAO) and the International Maritime Organisation (IMO), may this year separately agree a basis on which all carriers by sea and air will limit their carbon emissions. Aviation is reported to be contributing around two per cent of global carbon emissions, and maritime transport more than three per cent. At issue, is whether such reductions should result from a form of taxation involving licensing with revenue flowing to governments, or whether the industries themselves should take measures to mitigate their emissions.
