A second runway plans in Gatwick Approved by the GovernmentA series of planned UK is the last to receive support in the expansion of the airport.
The Gatwick decision can lead to extra 100,000 flights per year. If Heathrow gets permission to build a third runway – The government said it supports it – This can mean 276,000 flights a year, Expansion of Luton Airport In addition, potentially add tens of thousands of.
If so much expansions will be realized by meeting the goal of being a net zero until 2050, large discounts will be needed in aircraft emissions.
Some segments can be made in relatively simple ways – for example, by replacing old planes with new ones.
The existing generation Airbus A320neo saves 15-20% more fuel than its predecessor. If you use less fuel, you will produce less emissions.
However, this will not go forward enough on its own.
Latest Progress to ParliamentThe UK’s climate observer, the UK Climate Change Committee (UKCCc) warned that emissions caused by flight “a risk for the British emission targets”.
Last year, flying emissions, UKCCc’s main flight type of Gatwick’s international entertainment flights – increased by 9%that an increasing demand for holidays abroad.
Although the UKCCC has not completely excluded airport expansion, it was warned that the government should look at measures to reduce flight demand.
The UK has legally binding targets to reduce the planet -heated emission levels, and by 2050, it contributes to its global target to prevent average temperatures increased by more than 1.5C.
Above this temperature level, scientists foresee significant effects on the rise of global sea levels, more extreme air and agriculture.
To prevent increased temperatures, there is a limit to determine the amount of greenhouse gas, such as CO2, to determine the share of the world, known as the Carbon budgets of the UK.
In 2021, the government adopted for the first time that carbon budgets of 2033 should include the country’s international flight and shipping share. This means that decisions to expand the airports may have a significant impact on the country’s climatic goals.
This means something big is expected In the next decades, “sustainable aviation fuels” or pure.
These are fuels that can be produced or captured from waste oils from raw materials such as wood, crops and agricultural waste.
Such fuels may result in much lower emissions than fossil fuels when they are burned, because they do not release long stored CO2 to the atmosphere.
However, in practice, environmental benefits may vary significantly depending on what they are done and how they are produced.
In addition, it is not too pure at the moment – and existing, it can be too expensive.
The government is trying to build a larger market for sustainable fuels, hoping that it will encourage production and reduce prices.
This year, 2% of the entire jet fuel provided in the UK this year should be accepted as sustainable and that it should rise to 10% by 2030 and to 22% by 2040.
In addition, a bill before the Parliament will establish a “income mechanism” for pure manufacturers – in fact, a minimum price for the fuel they provide to them.
Theoretically, it should promote more investment in this pure production.
However, it will be financed by a tax given to its customers to transfer extra costs to its customers. This can ultimately mean higher ticket prices for passengers.
In the long term, more radical solutions can be obtained, such as aircraft reinforced by hydrogen.
However, this will require one step change in aircraft design and major changes in airports. In addition, the affordable “green” hydrogen supply produced from renewable energy will require and infrastructure is not yet available.
Electric or hybrid aircraft may have environmental benefits, but still in the early stages of technology-and battery-powered aircraft is not considered to be a suitable option for long-distance flights.
