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.
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
I’m all for nuclear powered high speed electric trains.
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 👍
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.
That attitude is how you make no progress on climate
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
