The traveller’s guide to carbon offsetting your flights

The travellers’ guide to carbon offsetting your flights

I have a bit of a love-hate relationship with air travel. I love the places flying takes me, but I’m not a fan of the actual plane bit. But as well worrying about whether we’re going to crash, I’ve started worrying more about the environmental impact of flying, and especially the way it contributes to climate change. Flights account for around 2.5% of global carbon dioxide production at the moment, but the industry’s growing rapidly. And because planes fly high the atmosphere, the greenhouse gases they emit do more damage than on the ground.

New technologies like biofuels or electric planes are in the pipeline which could reduce flying’s environmental impact. But they’re a huge investment and need years of safety testing, so it’s a slow process. Until then airlines are trying to increase efficiency by reducing weight, carrying more passengers, using tailwinds and reducing distances through air traffic control (though cynics might say that’s more about saving money than the environment).

Regulations are starting to put pressure on airlines to reduce their impact, but the rising demand for flights is outstripping any reduction in emissions. There’s a crazy statistic that only 6% of the world’s population has ever flown, so there’s huge potential growth out there. I’m trying to cut down on flights and take the train where I can, but there are so many places I’d love to visit where I’ve got no choice but to fly. So is there anything we can do?

Carbon offsetting your flights

One of the ways it’s been suggested air travellers can reduce the impact they have on the environment is through carbon offsetting their flights. Carbon offsets are voluntary schemes where people can pay to ‘offset’ or make up for the emissions that their flights produce. It sounds good in practice, but not a lot of people use them. Many passengers don’t know they exist, but even more are confused (or dubious) about which schemes to use.

Offsets aren’t at all straightforward and they’ve often been controversial – some of the schemes are run by profit-making companies and there’s no standard certification to show which are worthwhile. There are also moral questions about whether paying to pollute makes people less likely to change their behaviour. So what’s the truth about carbon offsetting?

How does carbon offsetting work?

Aircraft engines produces greenhouses gases, particles and water vapour which are released into the atmosphere. It’s this mixture that makes them so polluting, but the focus of offsetting is on carbon dioxide (CO2) as it’s the most common greenhouse gas. Carbon offsetting doesn’t get rid of the carbon dioxide produced when you fly – that still goes into the atmosphere.

What it does do is try and make up for your share of the CO2 which gets released by reducing it somewhere else instead, which will slow help to down the global rise in carbon dioxide levels. This is usually based on measuring how many tonnes of CO2 are produced by each flight and investing in a project which reduces CO2 levels by the same amount.

Protecting the environment

There are two main types of offset project. First are forestry projects, which either stop existing trees being cut down or plant new ones. The trees act as a ‘biological sink’ by taking carbon dioxide out of the atmosphere. Then there are energy projects, which reduce the amount of fossil fuels used by investing in energy efficient products or renewable technology. Often these projects have social and sustainability benefits for developing countries too.

Sounds simple but any carbon offset project has to meet three criteria to be effective. There has to be additionality – which means the project wouldn’t have happened if it hadn’t been funded by the money from the carbon offsets. There has to be no leakage – so you can’t reduce emissions in one place if it means they’re increased somewhere else instead. And it has to be permanent – so it won’t be reversed in the future (which can be a bit of a challenge for forestry projects as how can you guarantee trees are never going to be cut down?).

How are carbon offsets calculated?

Various calculators have been developed to work out how much carbon dioxide you produce on a flight. The most basic just look at how many miles you’ve flown. The better ones also take into consideration your class of travel, the type of aircraft and how fuel efficient it is, the number of passengers it holds and the occupancy rate. But if you wanted to be super-accurate you’d need to take into account the time of day and weather too. Every carbon offset scheme calculates things differently – and some are a lot more comprehensive than others.

How much does carbon offsetting cost?

Because the calculators all work differently, the amount you pay varies too. I tested out a couple of the big calculators by looking at the amount of carbon I produced in 2018. Two long-haul return flights from the UK to the Caribbean and four short-haul return flights around Europe came out at around 7.5 tonnes. A short European flight (London to Geneva) is around €10, a longer one (London to Malta) around €20 and the UK to the Caribbean around €60.

It was interesting to see is that making a stopover can increase the amount of carbon you produce. As does flying in business or first class instead of economy – their lower passenger numbers mean they’re a less efficient use of space. A London to Dubai flight would cost €50 to offset in economy versus €95 in business and €145 in first. With a lot of people up the front end of the plane travelling for work, I wonder how many companies use offsets?

Which scheme should I use?

The big issue with carbon offsetting is choosing which scheme to use. There are a baffling number, most of which make lots of impressive claims and have websites covered in pictures of lovely green forests. But they’re not all regulated and how some are funded is a bit fuzzy. Sussing out the good from the bad is a full-time job, so it’s usually a case of taking recommendations from environmental organisations who’ve looked into them and certified the best.

Carbon offsetting with your airline

The easiest option is to offset directly with the airline when you book your flight. You just pay an extra fee on top of the flight cost which is donated to a carbon offset scheme. Around a third of airlines have some sort of carbon offset programme, but how they work varies. Some have their own schemes and others are enrolled in other people’s. Some are upfront about their offset programmes and others hide them away. Some give you the option to offset before you book and some only after (which means you can’t see the cost until after you’ve booked).

Among the airlines which are doing good things with carbon offsets are Qantas whose Future Planet scheme claims to be the largest airline offsetter. Their projects uses a mix of reforestation, forest protection and renewable energy projects – plus they offset their own staff travel. Other verified schemes include Air Canada’s work with Less Emissions, Brussels Airlines with CO2 Logic, KLM’s CO2ZERO and Austrian Airlines with Carbon Austria.

Final call

Down the other end of the spectrum is Ryanair (why am I not surprised?), who recently started a carbon offset scheme which costs £1 for a flight from London to Oslo. There’s no accreditation and they say the funds will be “distributed annually to environmental charities and NGOs as selected by our people”. Can’t say that hugely fills me with confidence!

If your airline has a carbon offset scheme, take a look at their website before you buy to see if it’s worthwhile, or whether you’re better off spending your money elsewhere. Some of the things to look at are how offsets are calculated (is it just mileage-based or more comprehensive?), what type of projects they fund, what percentage of the money is used in admin and whether they’re certified by a verifed scheme like Gold Standard or Carbon Standard.

Carbon offsetting directly

Some airlines like Emirates choose not to offer offsets. Or you might want to offset flights you’ve already taken. And if you want to choose which type of project – or even which specific project – you fund, it’s usually best to offset directly. Gold Standard is one of the most widely recommended bodies and the name I kept coming across. It’s a Swiss non-profit founded by a group of environmental groups and NGOs including the WWF. Their projects are based in developing countries and combine reducing CO2 with sustainable development.

They don’t have their own calculator but they do have links to a couple where you can work out the amount of carbon you’ve used then choose a project to donate to. Otherwise they have various partners who run Gold Standard certified projects around the world:

  • Atmosfair in Germany (who have a particularly good calculator which rates airline efficiency and includes other greenhouses gases as well as CO2)
  • MyClimate in Switzerland
  • Climate Care in the UK
  • Terrapass in the US.

So is it worth carbon offsetting?

Does carbon offsetting really make a difference? The same amount of carbon dioxide is going to be released on that flight whether you offset or not. And it’s been argued that offsetting is just a way for people to feel less guilty without having to change their behavior. But if you do have to (or want to) fly, then offsetting has got to be better than doing nothing. My 2018 flights came in at €175 to offset – enough to make me think about my flying habits.

Environmental group Ethical Consumer advise choosing an individual project to fund rather than letting the company pick, so you know where your money’s going. And that energy efficiency projects are a better option than forestry as they directly reduce the amount of fossil fuels being used. They also recommend wind and solar over biomass as it’s less likely to be misused. Choosing a specific project does usually mean you pay more but it means you know you’re getting the maximum benefit. Otherwise you can just create your own offset by working out what you would have spent and donating it to a charity that’s helping the environment.

What else can I do to reduce my impact?

Well obviously the best way to reduce your impact is not to fly at all! That’s not going to be practical for most people, but it’s often possible to cut down or change how you fly.

Reduce short-haul: Short-haul flights under 500km are comparatively the worst polluters because it takes a lot of energy to get up and down. So could you take a train or bus instead sometimes? This can massively reduce the amount of carbon you produce – a return trip from London to Paris return would produce 110kg of CO2 by plane versus 6.6kg by train.

There’s often the idea that flying is a lot quicker but when you add in time getting to and waiting at the airport it often doesn’t make much difference. 80% of flights from the UK to Europe are to destinations which you could reach by train within a day. Looking at my travels last year, the Alps and Munich could have been pretty easily done by train, so cutting right down on short-haul flights is definitely something I’m going to prioritise this year.

Choose a more efficient airline: The airline you fly with makes a big difference to your emissions. Lower impact airlines usually have more modern, fuel-efficient planes and carry more passengers. Atmosfair have some very helpful rankings to help you decide – surprisingly charter airlines like TUI and Thomas Cook are among the best, as well as Jet2, Air Transat, KLM and Air New Zealand. And worst are US carriers United and Delta’s regional networks.

Choose a more efficient flight: The type of flight you choose can also have an impact. Because take off and landing are when the largest amount of emissions are produced, it’s better to fly direct rather than stopover as you only have to do it once. Flying economy instead of business or first-class also reduces your impact (sadly not a choice I ever need to make!).

Apply some pressure: I said almost the same thing when I was talking about cruise travel, but pressure from consumers is so important in getting businesses to act in a more environmentally responsible way. The more people who ask about airlines’ emissions – whether that’s about their carbon offset policies or what tech they’re investing in – the more airlines will take things seriously if they think it’s having an impact on who we spend our money with.

    I thought the government added a green tax into all flights leaving / arriving the UK a few years ago to offset the damage?

    I’m very dubious of these schemes at present…there is very little transparency in the numbers.

    There was some really interesting scientific data that came out of America after 9/11 when they grounded all flights for a few days…the temperature in America reduced. It showed the environmental impact and how it’s contributing to climate change.

    Flights have become so cheap in the short haul market which is where most of the damage is done. These flights need to be either reduced or more heavily taxed.

    I’m all for change and sustainable travel but I don’t like money earning schemes if it doesn’t reduce the footprint in the long run.

    Companies need to look at the bigger picture rather than the profit…I just read an article about Air NZ looking at ways to reduce their plastic consumption on board their flights which should be tackled by the whole industry as well.

    Train travel is so easy in Europe between countries but not so easy in the South Pacific.

      The tax is Air Passenger Duty – it was designed to make flying a bit less attractive by costing more but it only applies to flights departing from the UK (excluding Northern Ireland or the Scottish Highlands), isn’t that much, and the money hasn’t necessarily been used to help the environment (interesting post about it here: https://www.responsibletravel.com/copy/blog-post-thirty-eight)

      The transparency is definitely an issue with offset schemes, and there being so many iffy ones does muddy the waters for the good ones. I think it’s going to need a major behaviour change to make much difference to climate change now though – or some serious regulation, but that’s complicated by air transport involving multiple countries and there being a lot of commercial pressure to keep growing. Definitely agree that in some part of the world you don’t have to fly but within Europe there’s almost a billion passengers carried on flights each year which is just crazy! x

        It would be fabulous if the governments could all work together to tackle climate change however that’s never going to happen unfortunately as we’ve seen by their actions over the past few years.
        Look at China, it’s now faster to take a train between major cities rather than flying and this has only happened in the past 10-15 years.
        Remember the days when you went on one flight a year if you were lucky; those days are long gone since the introduction of the cheap airline flight model which has made travel more accessible to the masses including myself.
        Cheap flights are like fast fashion; cheap, nasty and bad for the environment.
        I would be happy to offset my carbon footprint if the money went towards investing in better land transport links so that I didn’t have to fly at a future date…unfortunately planting a tree isn’t going to sort the issue out, better rail links would.

    I’m sceptical about some of the airline offset programmes so I’d be inclined to go with an independent non-profit making organisation. I learnt a lot from your post and I’m now more aware of how the airlines differ in their attitudes towards environmental damage and and will definitely be more mindful when booking or better still look into taking the train (which I prefer anyway)

    I never look at the extra bits after I buy the main flight, but the offset is a very good idea, at a time when school children are on strike because of what we are all doing to the environment… I dread to think with all my work (short haul) flying what I’ve done… In our Volvo we add something in next to the filler cap which helps reduces emissions… Sounds like something like that is needed to keep the 747’s in the sky and flying cleanly

      There are various tech solutions to reduce emissions but the problem is they’re so slow to market with all the safety testing that’s needed – and the rise in demand is outstripping any carbon saving. In reality the only thing that’s really going to help is a major change in people’s behaviour but that’s a tough sell!

    Wow I’ve really learned a lot from this post – I didn’t know the criteria for offsetting and I certainly didn’t know about Ryanair’s scheme! This kind of thing makes me frustrated because when there are too many options, some of which a bit iffy it becomes all too easy for people to write the whole thing off as a scam. What would be much better is a single government backed scheme, but the government haven’t even enforced recycling properly here (in Denmark for example it’s taken so much more seriously and people take heed) so I am guessing pushing carbon offsetting for the privileged few who fly regularly is some way off. 🙁

    It is worth remembering that the cost of First Class and Business Class flights to the customer subsidises Economy Class flights. Like everyone with a disposable income, I want to travel and see other parts of the world only accessible by the wonder of Jet Flight. It is therefore possible for more people to enjoy experiencing travel because of First Class and Business Class. I therefore celebrate Business and First Class travel for enabling millions of people globally to experience what some of us, Lucy, have come to take for granted.

    @Ryanair that is *so* not what is meant by carbon offset!

    My input as a relatively frequent business traveller:
    The stingier and less employee-friendly companies will accidentally be more carbon efficient, in their disregard for what condition their employees arrive in to work at the destination location, because they almost never fly business. Most companies these days try to avoid travel, for controlling travel budget reasons, favouring instead teleconferences or other web-based collaboration.
    One way that more employee-caring companies could end up being more efficient, is by allowing the employee to choose the flight route (within reason). Generally business travellers prefer as few transits as possible, to shorten the travel time. A pro-employee company will tend to allow that even when the route costs more, to reduce strain on the employee.

      Hi Elliot, I think it is to do whether they calculate it as straight emission levels or add an extra allowance for the emissions being released high in the atmosphere where they can be more damaging – so both are technically correct but the higher figure covers the effects more comprehensively.

    Elliot, Atomosfair includes “Contrails, ozone formation and other effects” in their calculations (click “Show detailed emission data” after calculating the CO2), which perhaps explains why it is so much more expensive.

    Nice post, thanks for doing that research.

    Rather than buying an offset, which can be a bit like funding a black box, I’d be more interested in joining a project and effecting a carbon drawdown equivalent to my emissions through my own offer of labour.

    Broadly speaking, say i have two one-week holidays a year, one might be a traditional sun and sand in the Mediterranean incurring a carbon emissions hit, the other one would be a working holiday on an accredited carbon offsetting project that would repay the carbon debt for my holiday in Greece or wherever.

    This sounds more appealing to me than paying for my sins in cash.

    I’m not sure if such schemes exist though; I looked at Climate Care but they seem tailored to organisations, not individuals, and their projects are overseas, so I end up incurring more emissions in the travel to get there. Maybe one such would be Trees for Life in the Scottish Highlands, but are there others you might be aware of ? I’d want one that was based on some accredited method of carbon offsetting calculation.

    Thx again,

    Pete

      That’s a really interesting idea – and much more personal responsibility that just paying for a project to be funded. I’m not aware of any direct carbon offset volunteer projects, but there are conservation charities and places like Workaway where you can work in return for accommodation and choose to help out with forestry or energy projects. Will definitely keep an eye out for more though.

    Hi Lucy,
    Just wanted to say thank you very much for writing this post. I found it a really useful summary and I’ve just donated to Gold Standard to offset a recent flight I have taken from the UK to Cambodia for work. What I liked about Gold Standard (on top of the fact that it is WWF recommended and seems to get the best reviews) is that I was able to offset my carbon emissions by donating to a project locally in Cambodia.

    I feel very much the same as you – I love the places planes take me but I also worry for the environmental damage I am contributing towards. I feel that every little bit helps in terms of our individual behaviour and as I go forward I will try to use public transport more, fly less and commit to offsetting future flights. Carbon offsetting certainly has it’s limitations but until we have electric planes, or whatever new technology is to come, its better than doing nothing.

    Best,

    Louisa

    Great post Lucy. You’re absolutely right, there are so many schemes out there to choose from and it’s best to choose wisely. RIPPLE Africa have been issued carbon offsets for our fuel efficient cookstove project in Malawi which is registered under the Clean Development Mechanism and is operated under the United Nations Framework Convention on Climate Change. The project is currently supporting over 40,000 households to change their way of cooking, saving over 80,000 bundles of wood per week. We are audited annually to verify the savings in carbon emissions so people can be confident that our project really is benefitting the environment in Malawi. This fuel efficient cookstove is a way of life and has significantly reduced Malawi’s greenhouse gas emissions. This is a great video about it https://youtu.be/9yJb9FTY5AM. Flying and offsetting is better than flying and not offsetting. https://carbonoffsetafrica.com/

    There really is no justification for flying a third of the way around the world for a beach holiday, but this seems increasingly the thing to do, so as to impress Instagram pals.

    Such a flight deposits pushing a year’s car use of CO2 into the upper atmosphere for every passenger.

    The only real justification for leisure flying is to visit relatives, but an annual holiday flight may just be acceptable, like it was back in the 1990s.

    The only offset which really works is to cut car use by equivalent mileage flown, which means that for a flight to Australia you should give up driving for a year.

      The social media pressure definitely plays a part, along with cheap flights – and a lot of business travel which I’m sure could be seriously cut back. Interesting idea about not driving as a form of offset, I don’t drive and mostly don’t need to travel by car but of course it depends where you live and how good the public transport is.

    Back in 2007, George Monbiot claims in ‘Heat: How We Can Stop the Planet Burning’ that the only possible excuse for flying is “love miles”, ie visiting immediate relatives. I think the big problem is ‘additionality’. If we have to do everything possible to reduce our emissions to keep heating below 1.5 degrees, what offsetting project can be seen ass additional?

      Interesting point, but I think for most people are so far away from doing everything they can at the moment, so I guess projects have additionality at present – but hopefully if people did more, then offsetting wouldn’t be necessary.

    Thanks Lucy,

    What a great, well researched and easily understandable article! I have just had a multi-flight holiday to the UK, Paris, Spain and Portugal from Melbourne Australia with two stopovers in Hong Kong on the way and Singapore on the return journey. I refuse to fly without a stopover to Europe as it is way too far and tiring especially in economy and without a stopover it takes a week to get over the jet lag. I’m now looking at ways to carbon offset my flights. I was chatting to a fellow demonstrator at a very large rally against inactivity on climate change in Melbourne recently (100,000 people plus) and he said he simply gives money to charities protecting wildlife but of course this begs the question of how a fair donation should be calculated. I already give regular small donations to many environmental and conservation groups. (I did catch the Eurostar London to Paris which is great and very comfortable and the high speed train from Paris to Madrid via Barcelona but this takes about 10 hours with an hour wait in Barcelona so it becomes as tedious as a long haul flight). Regards, John Young

      Thanks John, glad you found it useful. Making your own offsets to environmental charities is a good idea to as you can choose exactly where you want to the money to go, and you can use the offset calculators to get an idea of how much to pay.

    Hi Lucy,

    Thank you for posting an interesting, easy to read and informative article.

    I would like permission to use it as a link and referral on my website and onboard my tour boat for my guests if this is possible?

    I am also upgrading my EcoTourism Australia certification to a higher level and would like to use this as a guideline in my certification process.

    I look forward to hearing back from you.

    Kind regards

    I have visited your page as we are in the middle of a heated family debate about whether to fly abroad on holiday next year.
    As a mother, keen to preserve a living planet for my children, I feel very strongly that, knowing just how damaging air travel is for the environment, there really is no justification for leisure flying. An immigrant to the UK from Europe, I have resisted the ‘love miles’ argument, and refrained from flying ‘home’ for many years, despite the obvious convenience and emotional pull.
    My partner would love for us to travel ‘somewhere hot’ in the Mediterranean next spring, and we can not seem to be able to see the other’s point of view. I found your site while slim-chance hunting for some out-there, radical off-setting scheme that would allow us to travel with a clean conscience, knowing deep in my heart that no such option exists. The closest I have seen here would be for us to surrender use of the car for a year. Each. I’ll put that to him and see what he says 🙂 .
    You might want to include a link or reference to TreeSisters, who, while not offering direct off-setting solutions, are passionate about re-forestation on a huge scale, and a deep re-education of how we connect to Nature.

      Thanks for commenting. Unfortunately there’s no guilt-free offset system, the car idea would be interesting though. Somewhere hot in the Med might well be do-able by train though, although it can get expensive for families. Thanks for the tip on the TreeSisters too, I will check them out.

    Based on your “want to go places” here: https://www.ontheluce.com/travel-future/, I calculated your CO2 contribution.

    I took the locations and flight distances. I made each hop from one to the other to give you a break, except for one hop where I made a return to the UK before heading back out. This is probably not accurate since you would probably be heading home before other trips, etc.

    So, this is a *conservative* estimate.

    You would fly approximately 52, 568 miles.

    Based on the BlueSky CO2 model, you would be responsible for adding 2,786,104.00 pounds of CO2 into the atmosphere. I know you mentioned that CO2 that high up is more harmful, but don’t forget about the other pollutants that are acidifying all the oceans you’re flying over.

    So, in tons, you will be adding approximately 1,293 TONS of CO2 into the atmosphere. Just so you can travel. Thanks for that.

    Now, those are just air miles, which represent about 53 lbs per air mile. It is also very conservative, so I think it should be multiplied by about 1.5, but let’s call it an even 1,500 tons of CO2.

    Now, if you factor in the rest of your pollution, you would need to add all the cars, food, clothing — everything, to really come up with a number.

    Let’s see where you factor into the total miles flown each year: 52,481,606,750. If you did all of this travel in a year, you would be responsible for something like .001 % of that.

    What is 52,481,606,750 miles in CO2? 2,781,525,157,750‬ lbs.

    1,390,762,578 TONS of CO2.

    Let’s take a tree and assume it survive it’s planting.
    One tree when it reaches adolescence might pull in about 48 lbs of CO2 a year and maybe store about 1 ton after 40 years.

    Remember that number: 2,781,525,157,750 lbs of CO2 every year?

    You and everyone else would need to plant 69,538,128,943 trees every year. That is 69 and half billion trees. Actually, it would be more because immature trees don’t consume that much CO2 to begin with, so let’s double it to cover your 53 lbs of CO2 per mile.

    That’s 139,076,257,886 (139 billion) trees every year.

    Now, don’t forget that it will take quite a lot of energy to plant those trees. There will also be a lot of maintenance and replanting because trees will die.

    So, after ten years we’re looking at 1,390,762,578,860 (One TRILLION, 390 BILLION) trees planted? Really? That is the solution you have so rationalized?

    Here’s how you solve the man made climate change problem: stop flying.

    In the meantime, stop being a hypocrite. You fly for pleasure and money, not for necessity.

    You do NOT care about the environment or you wouldn’t do it. You are, literally, killing the planet.

    I assume you won’t have the courage to publish this, just like I am using an anonymous name. People don’t like the truth these days and only attack when being judged for their own folly. I hope you take this personally, however, and take a really good look at just how much damage you are doing.

      Hi ‘Moose’, I’m more than happy to publish this – I think it’s important to have these debates and you raise some interesting points. A few things to note though:

      My travel wishlist is of places I’d like to visit in my lifetime – I definitely wouldn’t be doing them all in one year, let alone every year.

      I travel by train as much as possible, so there are several places on the list (Italy, Scotland, Arctic Circle) I would travel to by train.

      In 2019 I’ve taken two return flights – one short haul and one Transatlantic – below average for most people, let alone travel writers. And in 2020 I’m taking part in Flight Free 2020 and won’t be flying at all.

      I completely agree that carbon offsetting is not a solution to climate change. People need to make changes to their lifestyles, but there also needs to be political and economic change on a larger scale.

      There are a lot of reasons people fly – not just holidays and of course that’s an area we should look to reduce – but if they are flying then is it not better to do something towards offsetting the damage done, rather than doing nothing? In the same way that surely it’s better to cut down on flying rather than frame it as an ‘all or nothing’ issue where it’s not worthwhile doing anything unless you give it up altogether?

      Educating people about their impact on the environment is important, as is providing information about alternatives – but shaming people for their choices is only likely to alienate them.

        You must admit though, that the main thrust of your blog is to educate people about the joys of travel, not the moral issues of polluting the earth. If you wrote a blog saying shoplifting is fun (which it is) people would question your morality, not expect you to say that you can later buy indulgences by sending money to the appropriate trade body.

          Of course is it – this is a travel blog and I would always encourage people to see the world. But travel covers a huge range of different experiences, it’s not just air travel/long haul/mass tourism, there are plenty of low-impact options too, and the tourist industry supports millions of people around the world (unlike shoplifting which I think you’d struggle to find any positives for…).

    Thanks for this very thorough treatment, Lucy. Until flying is against the law or subject to rationing, this kind of pragmatism is probably the best we can hope for.

      Thank you, yes cutting down is definitely the best thing we can do but until then it’s better to do something.
