Is it possible to have carbon neutral flying? The answer is no. Air traffic is a major source of greenhouse gas emissions and is on the rise. Flying is the least efficient mode of transport, with higher emissions per passenger km than any other. (1/3) #ClimateCrisis #Green

Air travel is difficult to electrify due to the weight and energy constraints of batteries. Instead, the industry promotes carbon offsetting, which is just greenwashing and does not address the pollution caused by flying. (2/3)#CarbonOffsetting #EnvironmentalImpact Photo:Trac Vu

So what can we do? Reduce, or eliminate, your own flying. Banning private jets is also essential. It's time for the industry to be held responsible for the damage they cause and for strict emission standards and bans on luxury flights to be implemented. (3/3) #SustainableTravel

#banprivatejets #FlyLESS Much much less. Think of flying as “emergency only”. We’re destroying ourselves and taking everything we love with it. Flying is not worth that.

@SaintPalermo @ScientistRebellion Is travelling by boat or ship any less polluting? Genuine Question.

@SaintPalermo just found the answer to my own question: https://innovate-eco.com/are-cruise-ships-more-polluting-than-planes/

Are Cruise Ships More Polluting Than Planes? | Innovate Eco

The travel industry is one of the worst offenders to environmental pollution and projections show that it is likely to continue growing. Planes and cruise…

@BogLoper @SaintPalermo the advantage of boats is that you can put a #sail on it, and it’s a lot more fun that way. Otherwise, for land based travel, #trains are pretty easy to electrify (no need for batteries since you can just put wires along the #rails ) and you can even have restaurants in there 🤤.

@tlaferriere @SaintPalermo I didn't mention trains as I used to work on the railways and prefer them as a mode of transport, except in the UK where they are overpriced and overcrowded. The question referred to ocean liners crossing seas, which are apparently more polluting per person than aircraft.

@BogLoper @SaintPalermo @ScientistRebellion The point is ships can be made green, because they float passively. Aeroplanes are doomed to be energy wasters, as they need to go very fast in order to merely stay in the air.

@Noordkaapfujin @SaintPalermo @ScientistRebellion Do you have any evidence as to how ships can be converted to run on green energy? There are many thousands of these floating around the world, mostly running on diesel. Passenger ships are in the minority compared to tankers, huge fishing trawlers and cargo ships.

@BogLoper @SaintPalermo @ScientistRebellion Ships have been propelled by wind power for thousands of years. I've been on a large ferry between Norway and Sweden that's battery powered (with a diesel as back-up).

Point is, from basic physics follows that aeroplanes will always use a shitload of energy compared to water or land based vehicles. Because air is a gas with a density of just over 1 kg/m³.

Geof Hughes 🖤Jan 9, 2023

@Noordkaapfujin @SaintPalermo @ScientistRebellion So why is it that the article I read informs that, per person, ships are more polluting than aeroplanes? Can a huge container vessel be powered by batteries, or those sails you are so fond of? In this high speed world we live in, how many are willing, or able, to take days/weeks to cross the Atlantic when an aeroplane takes a few hours. Not sure why anyone would make that trip anyway when there's the internet, but I digress.

Milonguero cyclista Jan 9, 2023

@BogLoper @SaintPalermo @ScientistRebellion Well, because those in power simply don't care. Shipping fuel is dirt cheap and environmental regulations are lacking big time.

My argument is about what is possible given the will to build it. Green ships are possible, green aeroplanes not. Because water can give a static support to te vehicle, and air cannot.

Geof Hughes 🖤Jan 10, 2023

@Noordkaapfujin Given the will, a lot of things are possible. From Europe to China and right across Russia, trains could carry more people and a lot more freight, cutting down on millions of car and truck emissions, if the will were there.

@ScientistRebellion Better rail infrastructure?
