Moderation is the last thing on people’s minds at Christmas. Shopping, travelling and eating reach peak levels – putting pressure on our planet. Even Santa poses a problem. If you don’t believe in flying reindeers, that sleigh must be rocket-fuelled to reach the supersonic speeds needed to travel around the world to visit hundreds of millions of children in just one night using conventional engineering.
The example goes to show just how many presents we buy and send each Christmas – creating problems with packaging and transport. And as the population increases, so does the pile of presents. To get round this, presents have got smaller and virtual gifts such as an experience day have risen in popularity.
This has an added benefit of reducing packaging and transport problems. But virtual presents have a carbon footprint too. Electronic downloads still have an impact, as data has to be stored and transferred, using energy. So everything we buy has some impact, even through the electronic process of buying.
So how can we have a greener, more sustainable but generous Christmas? Here are five gold circular things!
The amount of food wasted at Christmas has a massive carbon (and water) footprint. Using less and storing excess in a winter wonderland – your freezer – is a great way to avoid waste. If leftover food doesn’t go in the freezer, cooked turkey and vegetables will keep for up to three days in the fridge.
However, not producing excess in the first place is the best way to avoid waste. Portion size is a big part of this and so is cooking things you actually like. Just because something is traditional does not make it compulsory. For instance, sprouts can be very controversial – so, if you don’t like them, skip them. You could also try an alternative to the traditional meat option, such as a nut roast. Vegetarian and vegan choices at the Christmas dinner table can massively cut the impact of your Christmas.
Lower the impact of gifts through choices of paper and packaging. A lot of seasonal wrapping is non-recyclable as it is coated in plastic. This is concerning as plastic tends to spread everywhere – it has even been detected at the North Pole. A better approach would be to use wrapping paper made entirely out of paper. Gift bags are another great option – they can be reused and therefore help cut a massive amount of waste.
You can give twice if you buy your presents second hand from charity shops – supporting worthwhile projects while also reducing consumption. You can also buy locally produced goods and support your local economy. Buying second hand potentially halves the carbon footprint.
A typical T-shirt alone has a footprint of around 8.77kg of carbon dioxide and 2700 litres of water. If 1% of the 55.6m people in England alone bought just one second-hand T-shirt instead of a new one, they would be saving around 4.9m tonnes of carbon dioxide, the equivalent of driving 1,049 passenger cars for a year, and a whopping 1.5 billion litres of water.
Christmas decorations and fashion are basically the same every year. So celebrate your Christmas collection and reuse it, over and over again. It is a tragedy that only one in four Christmas jumpers are ever reused. According to the Carbon Trust, an artificial tree needs to be used around 10 times to have an equivalent footprint as its real counterpart.
There are few holidays that are so focused on being caring, helpful and generous as Christmas. So celebrate this and try to avoid buying unnecessary stuff that people don’t want anyway. Donations and acts of kindness really lighten the load on that sleigh. A colleague once bought me a toilet for a family in Sierra Leone. No wrapping, no plastic: the best present ever – and Santa didn’t have to lift a finger!
➡️Another gift idea to make your Christmas more sustainable might be to donate to Cool Earth, a high-impact organization that we thoroughly vetted.
Cool Earth is not only an offset scheme. It provides grant funding to rainforest communities, supporting community work in rainforest protection and ensures their voice is heard in agreements about the future of the rainforests.
You too can help to save our planet. A more liveable Earth is just a click away 👇

Join us for the second of our Kinder Conversations - the Sky has a Limit.
Following our investigation into the Future of Meat in February, we've turned our attention to the sky. We'll be talking about whether air travel can be more sustainable, and how.
We're delighted to be hosting this event in collaboration with our friends at TQ, the Amsterdam tech hub where we're based.
📅 When Monday 17 June 18:30 - 20:30
📭 Where TQ, Singel 542, Amsterdam
🎯 Why should I fly Kinder? To hear about the latest research and technology making air travel more sustainable. To find out what you can do to reduce the impact your flights are having. To share a drink with like-minded travelers, and sample some of our vegan snacks (including beloved Professor Grunschnabel ice cream, as seen at the Future of Meat event)
Here at Kinder, we believe that greener travel is one of the key ways in which we can tackle the climate crisis. Travelling green can mean a lot of things, but right now we’re concerned about the aviation industry.
If aviation were a country, it’d be a top 10 polluter - and C02 emissions from air travel are growing many times faster than any other form. We’re already in a very dangerous position, and although there are many potential solutions, we sometimes feel overwhelmed and uncertain about what to do about it.
That’s where Kinder Conversations comes in.
Kinder Conversations is a series of events which delve into the biggest issues facing the world.
At the Sky has a Limit, we’ll be bringing together representatives from research and technology, the aviation industry and the not-for-profit sector to talk about sustainable air travel. We’ll hear more about the problem, and a lot more about the solutions.
Plus, there’ll be time to get a drink from TQ’s bar (buying a drink helps our friends from TQ support more events like this), try some vegan ice cream, and chat to fellow travellers about the steps you can take to travel greener.

I don't have a driving license and when pressed about getting one by friends tired of chauffeuring me around I usually say I will only get one if I can drive something cool, like the Batmobile or a flying car. Unfortunately, I might have to honour that promise as it seems that flying cars are finally taking off (alas, no commercial Batmobiles in sight).
Indeed, several promising startups around the world are working to deliver the "car of the future" over the next few years. Like the Dutch company PAL-V that showed off a limited edition of its flying car at the Geneva Auto Show in Switzerland.
The PAL-V is a hybrid between a car and a helicopter (or more precisely, a gyrocopter), able to reach a top speed of 160 km/h on the tarmac but also get airborne in just 5 minutes, hitting airspeeds of 180 km/h over a range of up to 500 km. But since buying a PAL-V will set you back around € 350,000 I might have to pass on this one. Moreover, flying this beauty requires not just a driving license but also (understandably) a license to fly, and that's just too much for me.
Thankfully, other companies are developing vehicles that need no driver at all. Aerospace manufacturer Bell Helicopter, for example, is working on Nexus, an air taxi capable of taking off and landing in the middle of a city (whereas the PAL-V still needs a runway, albeit short, to get airborne).
Called VTOLs (short for Vertical Take Off and Landing), these aircraft aim to become sort of an Uber of urban air travel, bringing customers to the opposite part of the city or even to a nearby city in a matter of few minutes.
If you're at JFK airport in New York, for example, and have a meeting in Manhattan, instead of embarking on a 1-hour, Cosmopolis-style taxi ride, you could just hail a flying car and be downtown in 5 minutes.
Futuristic as it may sound, concrete plans to make it come true are underway. Earlier this month, German startup Lilium successfully completed the first test of its new five-seater Lilium Jet, an electric vehicle that, according to the company, will have a range of 300 km and a top speed of 300 km/h.
The reason electric flight is such an exciting area of research is not just because flying taxis will allow a handful of high rollers to drastically cut on their commuting time. Electric flying cars might be really good for the environment too.
A recent study published by Nature highlighted that, in some cases, flying cars could eventually be greener than even electric road cars, cutting emissions while reducing traffic on increasingly busy roads.
Moreover, developments in the field of flying cars could also boost the research on electric flight at large, including long haul electric flights, sort of the Holy Grail of aviation. And, as known, the civil aviation industry needs to find effective ways to lower its carbon emissions as soon as possible.
However, as explained by Hugh Hunt in an article on The Conversation that we republished here on Kinder World, "gaps in necessary technology and practical uncertainties beyond the cars’ promising physics mean that they may not arrive in time to be a large-scale solution to the energy crisis and congestion."
Let's get this one thing straight: most people prefer flying to other modes of transport, and we seem to do it more and more often. The airline industry is booming and 4.1 billion passengers have been transported last year. Almost every figure one looks at shows the impressive increase in flights over the last two decades.
Alexandre de Juniac, head of the International Association for Flight Transport proclaims: “In 2000, the average citizen flew just once every 43 months. In 2017, the figure was once every 22 months. Flying has never been more accessible. And this is liberating people to explore more of our planet for work, leisure, and education. Aviation is the business of freedom."
However, this ‘business of freedom’ runs on fossil energy carriers as planes still almost exclusively fly on kerosene. Kerosene is a fuel produced by oil refining and carbon dioxide (CO2) is the major product of burning kerosene. The 2-5% of all global CO2 emissions the aviation industry emits is caused by its fuel consumption (and choice). And unlike other fuels like diesel or gasoline, airlines don't pay taxes on kerosene in most countries — making cheap air travel possible.
In 2018 Europe’s biggest airline Ryanair became number 9 in the list of Europe’s biggest CO2 emitters and still claims to be the ‘greenest and cleanest airline’. Andrew Murphy – the aviation manager at the European Federation for Transport and Environment — argues that Ryanair the new coal when it comes to climate pollution. Ryanair CEO Michael O’Leary, on the other hand, dismisses such claims by saying the claims are ‘’complete and utter rubbish’’.
Other airlines, like KLM who partly uses renewable jet-fuel, are acknowledging the problem but they aren't too far behind Ryanair on the list of emitters.
The growth of the industry is not expected to slow down. India and China are the biggest growth markets, the latter alone is building 200 new commercial airports in the next ten years. Moreover, industry forecasts suggest that emissions will rise by 700% until 2050 which amounts to more than 4% of the world’s remaining carbon budget.
If we want to reach the goals of the Paris Agreement, every the average earthling has a quota of two tons of CO2 per annum but just a return trip between New York and Amsterdam generates three tons already.
Compared to other modes of transport planes are the biggest CO2 emitters per travelled kilometre followed by cars, buses and finally trains which are the least polluting. The CO2 emissions, however, are only one half of the medal. The impact of flying on global warming is different than most other transport as it happens in the air high above the ground where the processes that cause or reduce global warming happen. These include CO2 and nitrogen oxide emission but also cloud formation, ozone and soot as well as methane reduction.
The climate impact of the emitted greenhouse gases in the stratosphere are three times higher than on the ground. Flying also causes condensation trails and fog clouds in certain weather conditions. Such clouds can have a warming or a cooling effect on the climate. One way to improve the climate effect of flying would be planning better routes where warming clouds are avoided and the formation of cooling clouds is favoured — our current routes have an overall warming effect.
So, hypothetically, some flights with clever flight-route planning might even reduce global warming. However, as we don't have time to hypothesise, we need to find and urgently implement other ways to bring down the impact of flying, like using better fuels or even better planes.
