| There are many different models of private jet but the one flown the most often into Egypt ahead of Cop27 was the Gulfstream G650, which uses about 500 gallons (1,893 litres) of fuel per hour. | There are many different models of private jet but the one flown the most often into Egypt ahead of Cop27 was the Gulfstream G650, which uses about 500 gallons (1,893 litres) of fuel per hour. |
| If a private jet had managed to take off from Amsterdam - despite the demonstrations - it should have taken about five hours to reach Sharm el-Sheikh, using about 9,465 litres of aviation fuel. | If a private jet had managed to take off from Amsterdam - despite the demonstrations - it should have taken about five hours to reach Sharm el-Sheikh, using about 9,465 litres of aviation fuel. |
| The Department for Business, Energy and Industrial Strategy (BEIS) says 2.5kg (5.5lb) of CO2 is emitted for every litre of aviation turbine fuel burned. So this flight would produce 23.9 tonnes. | The Department for Business, Energy and Industrial Strategy (BEIS) says 2.5kg (5.5lb) of CO2 is emitted for every litre of aviation turbine fuel burned.

| But to "capture the maximum climate impact" of flights, BEIS recommends, CO2 emissions figures should be multiplied by 1.9 - to reflect the non-CO2 emissions released by planes at high altitude, which, scientists say, increase the warming effect. | But to "capture the maximum climate impact" of flights, BEIS recommends, CO2 emissions figures should be multiplied by 1.9 - to reflect the non-CO2 emissions released by planes at high altitude, which, scientists say, increase the warming effect. |
| Therefore, the total emissions for this flight would be 45.3 tonnes of CO2 equivalent - and if the maximum capacity of 15 was filled, each passenger would be responsible for about three tonnes on their journey. | Therefore, the total emissions for this flight would be 45.3 tonnes of CO2 equivalent - and if the maximum capacity of 15 was filled, each passenger would be responsible for about three tonnes on their journey. |
