The research team at the Norwegian University of Science and Technology also found that India's share in global CO2 emissions from domestic aviation was the third highest at 1.5 per cent. "The countries with the highest absolute domestic aviation CO2 emissions (global percentage share in total CO2 aviation emissions in parentheses) are the USA (13.4 per cent), China (8.9 per cent), India (1.5 per cent), Russia (1.2 per cent), and Japan (1.1 per cent)," the authors wrote.
