  It has been noticed that through COVID-19 greenhouse gas emissions had a
sudden reduction. Based on this significant observation, we decided to conduct
a research to quantify the impact of scientific conferences' air-travelling,
explore and suggest alternative ways for greener conferences to re-duce the
global carbon footprint. Specifically, we focused on the most popular
conferences for the Artificial Intelligence community based on their scientific
impact factor, their scale, and the well-organized proceedings towards
measuring the impact of air travelling participation. This is the first time
that systematic quantification of a state-of-the-art subject like Artificial
Intelligence takes place to define its conferencing footprint in the broader
frames of environmental awareness. Our findings highlight that the virtual way
is the first on the list of green conferences' conduction although there are
serious concerns about it. Alternatives to optimal conferences' location
selection have demonstrated savings on air-travelling CO2 emissions of up to
63.9%.
