How many flights have you not taken in the last years out of concern for #ClimateChange?

My intuition is that for the vast majority of us the answer is: zero 😞

That’s true for me, at least. (The last time I used a plane was almost five years ago, but in my case it’s just because I had no business trips or holidays overseas while my kids were very little.)

Air #travel is one of the things I find most difficult to say no to for environmental reasons 😢

@tripu how many flights I have not taken? Well about 853 million in 2022.

How many because of climate change? I think all of them, since it is a reason I fly less.

Money and time are other motivations though.

@tripu I can't point to an individual flight I didn't take to reduce my impact on climate change.
But, I can point to a total lifestyle change where rather than flying 100+ times a year, I fly maybe a handful of times in a year....

@colo_lee

Is that change due to environmental concerns, or to personal circumstances? Just curious.

@tripu A mix of both. It was clear that business travel lifestyle was unsustainable for me personally and for the planet.

@tripu I am not flying since 2018 and I don't think I'll ever fly again. #climat #environnement

@martinhamel

How do you feel about the restrictions that’ll impose on you, making travel much more tiring and time-consuming or even sometimes impossible?

@tripu isn't air travel around 5% of emissions? It's never even been on my mind to reduce it. Budget and time are my only restrictions for air travel. I've changed more in other areas, like going everywhere in my city by bike. I don't even take public transport.

@ImperfectIdea

Where did you find that 5%?

It seems it’s even less! 1.9%–3.5%. And that includes freight by plane.

That’s “good news”: I thought it was much higher. It’s probably best to focus on other actions, as you said.

One real problem is that air travel is the only type of travel for which there is no viable alternative to fossil fuels, because batteries can’t pack energy densely enough for takeoff.

@tripu yes, I was rounding up, and even then it's really minor. That's why I think more about other areas like commuting.
