Hi aviators! As a fact, I am writing my Master's thesis at the moment on sustainability in air transportation, and this thread is a gold mine of opinion and professional view for me to analyze. Just wanted to say thanks for speaking it out loud!

It would be very interesting to me to have a genuine comparison of my pollution levels in a real world situation. I know what my car emits and can calculate how much that is over 250 miles between Newquay and Gatwick but what does an ATR72 emit over a one hour sector? Not sure how this is all measured but would like to sort fact from fiction!

We're away ATM having driven to The Netherlands, and it reckons we've emitted .49 tonnes of CO2.

Just attempted to calculate from published data and flying on the ATR72 is roughly 3 or 4 times as polluting over that sector per passenger than driving, but, of course that will be way out if the aeroplane is not full or I put five people in the car opposed to my calculation for one person. Of course I may be wrong.

not really surprising is it? You're not trying to propel your car to 20,000 ft and 280 kt - well you might be but...............

‘Magical thinking’: hopes for sustainable jet fuel not realistic, report finds

IPS report says replacement fuels well off track to replace kerosene within timeframe needed to avert climate disaster

“While there are kernels of possibility, we should bring a high level of skepticism to the claims that alternative fuels will be a timely substitute for kerosene-based jet fuels,” the report said. Chuck Collins, co-author of the report, said: “To bring these fuels to the scale needed would require massive subsidies, the trade-offs would be unacceptable and would take resources aware from more urgent decarbonization priorities.

“It’s a huge greenwashing exercise by the aviation industry. It’s magical thinking that they will be able to do this.”

Tells you everything you need to know about the quality and impartiality of the "report".

Not surprising but very relevant to whether we should be encouraging flying domestically if there is another practical way.

Yes, I should have added several emojis for the 'progressive' view. They are certainly progressing in one direction! However, that is the kind of thing that has been circulating for 30 years.

It's a good question - In the last couple of months I've flown, driven and trained up and down the Uk a fair bit - driving was worst by far - the roads were packed, there were interminable road works and it was highly stressful. Train & plane - good and bad on both - delays and cancelations on both but also very easy trips as well. Both more cash-out that driving of course.

Portugal announces: New international airport announced as European country celebrates record tourism. The government has also said it would build the long-delayed high-speed train connection between Lisbon and Madrid.
The airport will be built in the municipality of Alcochete, across the River Tagus from Lisbon, Prime Minister Luis Montenegro announced on Tuesday after decades of back-and-forth over the location.

The new airport will be built at the site of a military airfield in Alcochete, about 40 km (25 miles) east of Lisbon, and should the ready by 2034. This location has been favoured by an independent technical commission, which had studied several possible sites.

Infrastructure Minister Miguel Pinto Luz said the project would cost up to 9 billion euros ($9.74 billion), adding it would be built using EU funds, public-private partnerships and airport tariffs and not through the state budget.

The new airport will replace Lisbon’s Humberto Delgado airport, just near the city centre, but the current airport will be expanded while the new airport is being built.

The government has also said it would build the long-delayed high-speed train connection between Lisbon and the Spanish capital of Madrid by 2034.

“But it’s true that the industry has been slow to pick things up. We are now trying to find solutions, but we are working at this problem and realizing it’s a lot harder than we thought. We are late to the game. We are in the dark ages in terms of sustainability, compared to other sectors.”

Last week I detailed from Portugal: "The new airport will replace Lisbon’s Humberto Delgado airport, just near the city centre, but the current airport will be expanded while the new airport is being built."

Today I read from South Africa:
New multibillion rand airport aims to rival Cape Town International

Plans for the Cape Town Winelands Airport near Durbanville are advancing after South African entrepreneur and managing director of rsa.AERO, Nick Ferguson, announced that the private airport group has signed a 15-year agreement with the German airline Lufthansa Group.
Cape Town News Website
So, who is going to tell these people NO - we need to cut back on air travel?
