Air New Zealand has abandoned a 2030 goal to cut its carbon emissions, blaming difficulties securing more efficient planes and sustainable jet fuel.

The move makes it the first major carrier to back away from such a climate target.

The airline added it is working on a new short-term target and it remains committed to an industry-wide goal of achieving net zero emissions by 2050.

The aviation industry is estimated to produce around 2% of global carbon dioxide emissions, which airlines have been trying to reduce with measures including replacing older aircraft and using fuel from renewable sources.

The only way we make air traffic sustainable is by only travelling by plane when absolutely necessary and by not ordering stuff to be delivered ASAP so it can be shipped by boat instead.

Four people in a Chevy Suburban with a V8 pollute less to travel the same distance than if they do it via the air. Air traffic pollution is very, very bad, especially since it's released at altitude, and yet air traffic keeps increasing, especially for leisure.

And before someone comments about the ultra rich and their private planes, their emissions is basically nothing compared to the rest of air traffic.

[–] deranger@sh.itjust.works 22 points 3 months ago (4 children)

Air traffic altogether is only 2% of global emissions. We could focus efforts to reduce emissions elsewhere without the negative effects on logistics and people traveling. Even if you completely eliminated all air traffic tomorrow it would be insignificant compared to other sources. Not that I think it’s a bad idea to reduce emissions from air traffic, but it’s going to highly impact people’s lives for barely a dent in emissions.

[–] Kecessa@sh.itjust.works 23 points 3 months ago (1 children)

2.5% of emissions but 4% of global warming impact due to where the emissions happen. That's 1/25th of the global warming.

[–] oce@jlai.lu 19 points 3 months ago (1 children)

You can always detail something and say it's only x percent. Every percent counts, and we have to start with the ones that are not vital. Planes for vacations or luxury mangoes are very far from being vital.

[–] deranger@sh.itjust.works 6 points 3 months ago (7 children)

The way I see it, you’re taking away things people enjoy for a minuscule impact on climate. This will just piss people off for little benefit, and it’s not how you get people on board with the big changes we need to address the worsening climate. It’s like having to use shitty straws when industry is pumping gigatons of shit into the atmosphere. I believe the money pressure on airlines to use more efficient engines is actually doing a decent job at incentivizing efficiency in the air sector; it’s elsewhere that needs to be addressed harshly.

[–] roguetrick@lemmy.world 8 points 3 months ago* (last edited 3 months ago)

If externalities were actually enforced on the air sector, it would be completely replaced with high speed rail except for travel across the ocean, and even then shipping would become more prominent. The problem of giving free passes is you are artificially strangling the alternatives. It becomes much more cost effective to build high speed electric rail when your only option for jet fuel is biodiesel or paying the real costs of climate impact.

[–] oce@jlai.lu 5 points 3 months ago

It is not taking away vacations or delicious fruits, there are many lower impact alternatives for vacations and food, you just have to get out of the habits and trends, there are great things to discovers everywhere.
Also, I don't advocate for prohibition but rather for reduction proportional to footprint. Your dream is to take the plane to go to another continent? Do it, but maybe once every 5 years instead of every year, and switch to train and discovery of your region with hiking for the other years.

[–] chaospatterns@lemmy.world 5 points 3 months ago

Right, it's a lot better to give somebody a better alternative first if you want the public on board. Build up public transit, build up regional and high speed rail and leave planes for long distances that are unfortunately suited for trains and cars (e.g. international, cross-continental, etc.)

[–] ohwhatfollyisman@lemmy.world 5 points 3 months ago

for a minuscule impact on climate.

who defines what is miniscule here? what if an oil baron deems 20% to be miniscule? do we all go swimming in their blackened beaches?

how is 2% miniscule? and who says that emission reduction exercises have to stop at 2%?

it's sometime very easy to minimise the seriousness of something with the clever use of generic statements. there are enough spin doctors already trying to pull the wool over our eyes--we don't need to help them by also shooting ourselves in the foot.

[–] Kecessa@sh.itjust.works 4 points 3 months ago

If we don't start taking away things that people enjoy then in a hundred years it won't be an issue anymore 👍

[–] kaffiene@lemmy.world 2 points 3 months ago

That attitude is how you make no progress on climate

[–] AA5B@lemmy.world 2 points 3 months ago* (last edited 3 months ago) (1 children)

I start in a similar place but go the other direction. Airline travel is an important personal luxury, and crucial to global business or politics. While in the ideal it may be unnecessary, you’re not going to get people to give it up willingly, and they’d argue there’s no other option for such travel. So, what can we do?

The industry is great at adopting efficient technology but it can’t even keep up with growth in demand, much less reduce carbon emissions. So what else can we do?

  1. We need to drive/incent/require widespread usage of Synfuel/biofuel. At least then you’re just moving carbon currently active in the carbon cycle, rather than adding yet more carbon that’s been sequestered for hundreds of millions of years.
  2. Trains. We need to spend a lot more on trains. In this case we need to give people a more climate friendly option for travelling between cities up to 500 miles or so apart. We need trains to replace every short flight, so the carbon emissions from flying are at least only spent when there’s no other option. I read that France has started with bans on flights between a few cities with good rail service. Here in the US, we’re way behind with high speed rail but Acela is good enough to replace flying between a few cities, like Boston to NYC
[–] deranger@sh.itjust.works 1 points 3 months ago

I agree, having alternatives to air transportation is key. Trains are second. Just banning air transportation or imposing some fees will just make people angry and, I believe, hamper progress towards reducing the amount of CO2 we’re putting into the atmosphere.

[–] kaffiene@lemmy.world 5 points 3 months ago

Almost every emissions issue is a small part of the whole

[–] AA5B@lemmy.world 2 points 3 months ago* (last edited 3 months ago)

I believe the expectation is for that to change pretty rapidly.

Emissions from airlines is expected to continue growing and alternatives like biofuel/synfuel and expanded rail are too long term or not happening.

However the biggest emitters are being addressed. Scaling out renewable energy, ending coal, and scaling out EVs can significantly reduce the worst sources of carbon emissions (they’ll still be the worst but significantly less)

Then airlines become a contender and are no closer to a resolution

[–] eee@lemm.ee 17 points 3 months ago* (last edited 3 months ago) (1 children)

And before someone comments about the ultra rich and their private planes, their emissions is basically nothing compared to the rest of air traffic.

Yes but it's a hugely disproportionate amount for one person, how do people not get this?!

Using the same logic, i shouldn't do anything about climate change myself, because everything I can personally do is basically nothing.

[–] Kecessa@sh.itjust.works 5 points 3 months ago* (last edited 3 months ago)

I'm not saying it's not ridiculous for a single person, but even if they all started to take regular flights the issue would be pretty much the same, air travel in general is problematic, it's everyone's responsibility in this case. You see people complaining about emissions but they have travelled to 30 countries so far or they order shit from Amazon twice a week instead of buying locally or they decided to study 3000km from their home "to experience something new" but they come back any chance they get.

[–] AA5B@lemmy.world 2 points 3 months ago* (last edited 3 months ago) (1 children)

I really hate excusing billionaires in their private jets, but you could argue they do not have the money to make a difference in this case.

Technology improves efficiency as time goes on but the biggest change under airline control is switching over to biofuel so at least the carbon emissions are currently active carbon rather than adding carbon that had been sequestered for hundreds of millions of years. So biofuel exists and I believe has been approved, perhaps even internationally, however not much is made and it’s expensive. Private jets can’t spend enough to change that. We need commitments from major airlines to spend enough to invent biofuel scaling way up, and we almost certainly need government and international pressure or encouragement.

Of course that avoids the argument whether private jets are an excess the greater we can afford. And that avoids the argument that the rest of us need investments in rail so we have an alternative

[–] Kecessa@sh.itjust.works 2 points 3 months ago* (last edited 3 months ago)

No matter the type of fuel, you're taking carbon and releasing it at altitude, it's much better for the environment to burn that fuel at ground level if that's what you're going to do with it.

I know it's hard to accept but air traffic is just unsustainable as long as it's done using fossil fuel.

[–] GiddyGap@lemm.ee 0 points 3 months ago (3 children)

For these goals to be reachable, I think it comes down new tech. I don't think people are going to stop flying. For many it's simply not an option, especially if you have family far away.

[–] Kecessa@sh.itjust.works 3 points 3 months ago (1 children)

It's a choice people are making, moving from one side of the US to the other to go to school or for work is a choice, it's not normal in our current situation that we accept that and just think it's ok that these people travel across a continent multiple times a year. Same for people traveling halfway across the world for vacations, in the current state of things that's unacceptable. Humans have never had that much mobility in their history as they've had in the last 100 years, it doesn't mean it's a good thing for the world and it doesn't mean it's sustainable and should stay this way.

We need to stop relying on tech to come and save us, we have the power to do something right now.

[–] GiddyGap@lemm.ee -1 points 3 months ago

It's not always a choice. Only for the privileged.

[–] kaffiene@lemmy.world 2 points 3 months ago

Standard denier response. We don't need to do anything cos magic future tech will save us

[–] zeekaran@sopuli.xyz 1 points 3 months ago

"New tech"

Old tech, actually. From the 60s. It's called high speed rail.
