India among top 5 developing countries in aviation emissions in 2019, study finds
New Delhi: In 2019, India was among the top five economically developing countries in terms of carbon dioxide (CO2) emissions from aviation, a new research has found. Calculating «nearly real-time» aviation emissions using global flight data, researchers found that overall, the US, China and Great Britain were the topmost contributors, with 22 per cent, 14 per cent and roughly four per cent share.
However, among the economically developing countries, India was found to be the third biggest contributor with close to three per cent share in global CO2 emissions from aviation, following China at 14 per cent and the United Arab Emirates (UAE) at more than three per cent.
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.
The findings were published in the journal 'Environmental Research Letters'.
For their analysis, the researchers used the model, called AviTeam, which computes the fuel burnt for individual flights for the entire envelope based on a given trajectory.
