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.
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.
2.5% of emissions but 4% of global warming impact due to where the emissions happen. That’s 1/25th of the global warming.
I stand by my point; even if you eliminated all air traffic tomorrow it would barely make an impact. Efforts are best focused elsewhere that would have more of an impact on climate and less of a negative impact on people’s lives.
With this logic there’s no sector that would have an impact significant enough that we should worry about it.
I disagree. Electricity generation and industrial processes are emitting many times more greenhouse gases than air travel. If you eliminated all emissions from electricity generation tomorrow it would make a massive difference, far exceeding the 2% of air traffic. Looking at an EPA source electricity generation is 25%, industry is 23%, and transportation less air transport is 26%.

Then the trucking industry will say “But just our sector isn’t that bad, why not concentrate on ships?” and then the shipping industry will say “But just our sector isn’t as bad as electricity production!” and so on.
What you’re doing is exactly the same thing most people are doing to justify not making any effort “I won’t make a difference by myself, why should I do anything?”
I just don’t see people taking vacations or seeing relatives across the country as being the problem at this point in time. I think the limited resources we have to pursue environmental changes could be spent significantly better elsewhere.
If you came up with a revolutionary technology that saved an astounding 50% of the air transport emissions, you’ve eliminated 1% of total global emissions.
If you come up with a much more mundane technology that saves only 10% of electricity generation emissions, you’ve eliminated >2% of total global emission, more than twice the impact.
Limited resources would be much more effectively applied starting with the largest polluters.
I don’t think kneecapping air travel, pissing off many normal people, for little environmental benefit, is the way to get people to start seriously caring about emissions. It’s just going to fuel more reactionary bullshit and people completely missing the point, IMO.
As a side note, ships are way more efficient than trucking. Despite the scary numbers they put out, they also haul an insane amount of cargo.
It doesn’t require any resources for people to stop traveling thousands of km for leisure. It doesn’t require any resources for people to stop buying crap and expecting it at their door the next morning. In fact, it frees resources to stop doing both these things.
I know that ships are more efficient, read what I said again with your reading comprehension turned on so you understand my point.
Trains, for the win!
Edit: ok, NZ is a tough situation
But personal transportation and power are two places we Are making some progress, while emissions from flight keep growing. Current trends will make it a much bigger slice of the pie in a few years, but reducing emissions will take years of effort. It’s critical to start now
Electric trains ftw
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.
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.
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.
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.
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.
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.)
If we don’t start taking away things that people enjoy then in a hundred years it won’t be an issue anymore 👍
That attitude is how you make no progress on climate
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?
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.
Almost every emissions issue is a small part of the whole
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
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.
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.
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
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.

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.
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.
It’s not always a choice. Only for the privileged.
Standard denier response. We don’t need to do anything cos magic future tech will save us
“New tech”
Old tech, actually. From the 60s. It’s called high speed rail.
