The delegates arriving at the United Nations Climate Change Conference have been criticized on social media.
The day before the conference began, hundreds of environmental activists stopped private jets leaving Amsterdam's Schiphol Airport by sitting in front of their wheels and riding on bikes.
The start of the summit was preceded by 36 private jets landing at Sharm el-Sheikh.
There were 24 of them that came from Sharm el-Sheikh.
Both airports should be used by delegates, according to the website.
The majority of the flights were from the United Kingdom.
There were two from the US to Cairo.
There may have been more scheduled private flights because it was not possible to track them.
The use of private jets to fly to COP26 in Glasgow was investigated by the reality check show.
There have been less world leaders at the Sharm el-Sheikh summit.
Carbon dioxide is produced from burning fuel by flights. Global warming is caused by these.
Emissions are worse than any other form of transportation.
This varies a lot depending on the situation.
Private jets emit more emissions than commercial flights.
The most frequently flown model of private jet is the Gulfstream G 650, which uses about 1,500 gallons of fuel per hour.
If a private jet had taken off from Amsterdam, it would have taken about five hours to reach Sharm el-Sheikh.
According to the Department for Business, Energy and Industrial Strategy, CO2 is emitted for every liter of aviation turbine fuel. This flight would produce 22 tons.
To "capture the maximum climate impact" of flights, the BEIS recommends that the CO2 emissions figures be increased by 1.9 to account for the non-CO2 emissions released by planes at high altitude.
The total emissions for this flight would be 45.3% of CO2 equivalent, and with a capacity of 15, each passenger would be responsible for about 3 tonnes on their journey.
The emissions figures don't include the emissions associated with making the private jets.
If the delegates had opted for a commercial flight from Amsterdam to Egypt, their emissions would have been about half a tonne per person.
Even though a commercial flight uses more fuel, it can fly more people than a private jet and produce less emissions.
The prime minister and foreign secretary arrived in a plane that is a variation of the A330- MRTT.
A standard flight would use between five and six truckloads of aviation fuel an hour, depending on factors such as the amount of cargo and the altitude.
The flight to Sharm el-Sheikh will emit between 81 and 87 tonnes of CO2. The CO2 equivalent is 150 to 165 tons.
No 10 wouldn't say how many other people were on the flight.
The delegation traveled on one of the most carbon efficient planes in the world and carbon emissions from these flights are offset.
The international leader of the Energy and Climate Intelligence Unit said that focusing on world leaders taking private jets to COP 27 was missing the point.
He said that the emissions are insignificant compared to the decisions made at the summits.
If you want emissions to come down, you need scientists and stakeholders to ask the important questions.
