Cop26 in Glasgow could become the most carbon-intensive summit of its kind with a carbon footprint expected to be twice as large as the previous summit on climate change.
Around 102,500 tonnes of CO2 equivalent (tCO2e) is due to be released by the summit - a preliminary report for the UK Government by consultants Arup states.
However, Cop26 has been a significantly bigger event than any other cops so far.
More than 30,000 people were expected to attend the conference and said around 60% of the CO2 emitted comes from international flights.
When Madrid hosted Cop25 in 2019, 51,101 tCO2e was produced.

The UK Government said this year’s summit is the largest climate change conference so far, and the Arup report includes emissions from both the blue and green zones.
The Arup report said its figure of 102,500 tCO2e represented “the best working assessment of the emissions from the event”.
Dr Doug Parr of Greenpeace UK said: “The meeting in Glasgow is not supposed to be a demonstration of sustainable lifestyles, and it shouldn’t be judged in those terms.
“But the failure to reach any meaningful agreement about limiting aviation’s vast carbon emissions – at a conference where 60% of their emissions came from aviation, with a backing chorus of media outrage at the private jet hypocrisy of the elites – really highlights the lack of equity in these talks.
“Creating loopholes for the use of the rich not only maintains their disproportionately high emissions, but makes it so much harder to persuade anyone else to cut.”
Delegates have been asked to consider low-carbon methods of travel to Cop26.
A spokeswoman for the UK Government said: “As official UNFCCC figures show, Cop26 is a substantially bigger event than other recent Cops, with over 39,000 participants as against nearly 27,000 at Cop25.
“Cop26 will be a carbon neutral event and will be the first Cop to demonstrate carbon neutrality validation through PAS2060, the internationally recognised standard on carbon neutrality.
“As part of its analysis, the Government has for the first time included both the full blue and green zone impacts, giving a fuller and more accurate picture of emissions from the site.”
The Government said the Arup report is a baseline assessment which would not fully reflect many of the emission-reduction measures, while final emissions will be confirmed following the event.
