Batman: But we ban plastic bags and exponentially increase tourism. Tourism surely must incur a massive CO2 cost. How many plastic bags do we need to make disappear to offset CO2 released on one flight between Auckland and London on the most environmentally friendly aircraft? Please add up all the plastic bags used by all the crew and passengers in the entire journey.

Totally agree,

AirNZ are engaged on one of the biggest greenwash exercises NZ has ever experienced,

There own figures

https://p-airnz.com/cms/assets/PDFs/Air_NZ_GHG_Inventory_-Report_2018.pdf

Show their emission have grown every year since they started recording them and were 20% higher than their 2011 base year.

- and they have the gall to host a "sustainability" event promoting personal flying devices that are going to be as cheap as taxis ( that are apparently just around the corner- hah!,) and removing plastic swizzle sticks from their aircraft... talk about focussing on the big issues....

So what should they do? Nothing? Close up shop and go home? Despite being an airline, they fund conservation, have invested in fleet of electric cars that will eventually become cars that individuals own in NZ, and are making an effort to show that they can and will remove plastics as and where they can. I have nothing to do with AirNZ, but bagging them for the efforts they do make won't help.

I'm currently in Asia. If I buy an iced tea, it comes in a plastic cup, with a plastic lid and a plastic straw. They then give you a small plastic bag "carrier" - think plastic bag that the cup sits in with two handles - because apparently putting your hand around the cup is too hard. Buying a coffee? It comes in a small plastic bag, with handles and a straw - perfect for hanging over the handlebars of your bike or indicator stalk of your car (cause that has no other purpose I believe, but that's for another topic!). The sheer amount of plastic used here over that which we use in NZ is astounding! So any reduction made by an NZ company, no matter how small, is a great step in the right direction from my perspective.

Bashing a company for looking for ways to be more environmentally sustainable and responsible will not help.

I'm hoping you didn't infer any connection between between global warming and plastic bags. My only intention in them both being the same post was to make a point about forcing people to do something, unwashed or not.

Plastic bags do contribute to climate change as a result of the production process however that only part of the reasons to ban them. Other reasons are they do not breakdown and become a very long-term problem, they can travel large distances and make their way into the oceans. They are harmful to human life as the fragments and particles enter the food chain and are ingested in our food. They are hard to recycle, and NZ currently is not recycling plastic shopping bags. Plastic bags are polluting the land and the waterways including the oceans and are very harmful to animal life. They are impacting on the ocean life which is a foundation of our food chain. The plastics are mistaken and food souce and by sealife and birds. Animals also become entangled and die.

They are alternatives that are sustainable and reusable.

A couple of different sources both suggest aviation accounts for ~2% of global emissions, so while it's the hardest to decarbonise, it's also one of the smallest at the moment. A 787 uses about 2.4L/100km per passenger, which puts it roughly on par with driving a mid-size car the same distance with 3 or 4 passengers.

Distance between Auckland and London is 18,324 km. And don't forget it's usually at least a two way trip. And i like how they like to say they've calculated the math to a per person number, so let's now multiply that by about 300.

The government is doing that to the domestic Oil and Gas industry...

If climate change is as dangerous as it is made out to be, I think Air NZ should start by capping its aviation emissions by halting any growth not offset by efficiency....

wellygary: ... so when airlines cry how much higher fuel prices are hurting them ask them how much they pay per litre...

$US754/tonne according to the IATA website (interestingly 34% higher than this time last year). So at an average density of 0.8 that is $US0.60/l or $NZ0.91/l at today's exchange rate. For a wider cut fuel type than petrol.
Are you suggesting airlines be taxed for the use of the sky? Or should any tax be purely punitive for destroying the earth?
And the higher fuel costs are passed onto the customer, so they are ultimately the ones doing the crying.

So the B777s that replaced the B747 were reportedly 20% more efficient.
The B787s (when they actually manage to fly) are similarly more efficient than the B767s they replaced.
Likewise the A320s have the same fuel burn as the old B737-300s they replaced while carrying 30 more people.
And the A320Neos due to arrive are up to 25% more fuel efficient than the current ones.
So growth is being offset by efficiency.

No, but they should pay the same environment (ETS) taxes we pay on petrol now,

why should you pay the ETS on a flight from Auckland to Wellington? but not from Auckland to Sydney?

The 'smoke' has proven detrimental health effects due to particulates and NOx it contains, and for that reason should be reduced.

Well, the pickup truck owner will tell you that it's your fault for not wearing a face mask, so maybe you should just move somewhere else...

Too much effort involved in posting a picture of King Cnut. But you get the idea.

But he lives by you, not me. I am at least 30m above sea level at the moment, so don't need to move anywhere.

only partially not fully offset,

Yes the new planes are more efficient, but they have more of them and are flying to more places, so overall their emissions continue to grow....

If they were prepared to cap their emissions and only expand based on what they can offset by newer better aircraft that would be a real step...

You do realise that Cnut supposedly sat on the beach to show his followers that he couldn't control the tide?

I.e. he was proving he was just a man.

Expansion is driven by demand. Limiting capability is a wonderful environmental plan but a disastrous fiscal one.
I'm sure you have forgone any sort of air travel in your life given your posts, but for those continue to travel, the environmental ethics of any particular company would rank way behind cost, safety and convenience.
I'm growing tired of people shouting "Quick, everybody else do something!".

Yes. He proved he did not rule or control nature (in fact he ascribed that to a higher power). Particularly true from an insignificant country in the South Pacific.
