In a July update, Google changed the way its carbon calculator, which is part of its flight search aggregator service, works so that it no longer counts

emissions from planes that aren't carbon dioxide. Google told its users about this in July, saying that the decision was made "after recent talks with academic and industry partners."

It is well known that air travel does a lot of damage to the planet. Just burning aviation fuel produces a lot of greenhouse gases, including carbon

dioxide and other gases that contribute to global warming and climate change. Aside from this, planes and equipment used on the ground also

release something called ultra-fine particles, which are dangerous air pollutants. Also, aviation is the main source of ozone, which can hurt the

respiratory and cardiovascular systems of people.   Even though only 1% of the world's population is responsible for half of

the pollution caused by aviation and almost 90% of people have never flown in their lives, commercial aviation was responsible for about 2.4%

of the world's CO2 emissions in 2018. Since then, the number of flights has only gone up, and CO2 isn't the only pollutant caused by flights,

so underestimating emissions has some scary effects.   The BBC was the first to notice and report on Google's change.

It will show that aeroplanes do almost half of what they actually do to the environment. Experts say that this hides the real effects of air travel on the environment.
