A turizmus 1995 és 2021 közötti karbonhatékonyságának vizsgálata hazánkban az egyes üvegházhatású gázok szerinti bontásban.

This research analysed the tendencies of carbon efficiency of the section I (Accommodation and food service activities) in Hungary, broken down to the individual greenhouse gases listed in the Kyoto Protocol. Eurostat Database data have been used to calculate the carbon efficiency. The emitted quantity of greenhouse gas per unit of gross value added (carbon efficiency) has decreased significantly over the period (1995-2021) for carbon dioxide, with a significant improvement for methane emissions. Nitrous gases, perfluorocarbons and sulphur hexafluoride, nitrogen trifluoride showed no significant change, while emissions of hydrofluorocarbons showed an increasing trend. These gases replaced the former ozone depleting substances as refrigerants after the Montreal Convention. [ABSTRACT FROM AUTHOR]
