A travel lover who has visited more than 40 countries uses ‘clever hacks’ to reduce her carbon footprint from packing less than 10 kilos to bringing her own plastic food containers so she can have ‘leftovers for brekkie’ and asking hotels ahead of time to remove any free toiletries.

Caitlin Weich, 31, from Dublin, Ireland, tries to avoid flights at all costs and has travelled more than 1,800 miles from Greece to the UK using only buses, trains and ferries – while her partner, Adam Boyle, 28, has trekked all the way to Japan without boarding a single plane.

To reduce their impact even further, the couple have devised a wide range of carbon-cutting techniques, including packing a ‘capsule wardrobe’, a small collection of clothes that can be combined into an outfit for any occasion.

Caitlin also travels with a pair of chopsticks and a spoon to avoid using disposable cutlery, as well as natural shampoo bars and toothpaste tablets, which are plastic-free.

They avoid hotels when possible and otherwise always leave the ‘do not disturb’ sign on their door as Caitlin points out ‘you wouldn’t change your sheets and towels every day at home’.

In 2019, she visited nine countries including Greece, Italy, Slovenia, Croatia, Germany, Luxembourg, Belgium, England and Ireland, with just one flight and a carry-on bag of under 10 kilos, as every extra item translates into more greenhouse gases being pumped into the atmosphere.

Caitlin says she is happy to snack on any scraps, whether it’s a ‘piece of naan bread with a side of smoothie’ or ‘half a biscuit and a handful of nuts with some leftover stir fry’.

‘The next time you go on a trip with your massive luggage, take note of what you actually wore,’ Caitlin, who works in marketing, told PA Real Life.

‘Because the chances are you’re going to come home and half of the clothes in your bag will not have been worn, and you will have carried them halfway across the world and back for nothing.

‘If you go through the list of things that you can change, one of the biggest is look at your international flights.’

Caitlin, who was born in Namibia, has been travelling ever since she was a little girl because of her parents’ jobs.

‘From pretty much day one, I would be bundled up into the car and we would drive to see my grandparents in South Africa – that’s a long drive from Namibia,’ she said.

But aged 15, she became aware of her carbon footprint after filling out an online carbon calculator and being shocked by the results.

‘The biggest thing that was within my control and completely changed my carbon footprint was air travel,’ she said.

‘You look at how much carbon you produce in your day-to-day life and then add one international flight and it can double.’

Ever since then, Caitlin has been working out tactical ways of reducing her carbon footprint whilst travelling around the world.

To date, she has visited Namibia, South Africa, Botswana, Mozambique, Swaziland, England, Northern Ireland, Scotland, Wales, Hong Kong, New Zealand, France, Spain, Switzerland, Italy, Vatican city, Greece, Monaco, Albania, Croatia, Montenegro, Hungary, Austria, Czech republic, Germany, Netherlands, Ireland, the United States, South Korea, Malaysia, Singapore, Norway, Finland, Estonia, Iceland, Azerbaijan, Turkey, Canada, Australia, Slovenia, Luxembourg and Belgium.

The first and most important change Caitlin made was swapping flying for ‘sail and rail’ when possible.

‘That can literally be more than 50 per cent of your trip,’ she said.

Caitlin once travelled from Athens in Greece back to Dublin relying solely on trains, buses and ferries.

While her partner, Adam, has also proved planes are not the only way to cover great distances after he travelled from Dublin to Tokyo, Japan, over a three-month period.

‘He literally sailed, trained, bused the entire way to Japan,’ she said.

‘So it is possible, but it will take you a couple of months.’

Next up on Caitlin’s top tips for cutting carbon is accommodation. And while she usually tries to stay with friends and family she otherwise opts for green-energy hotels when she can and tries to ensure staff at the establishments have as little to do as possible.

‘Hotels, unless they are doing incredibly well, are buildings which remain partially empty most of the time,’ she said.

‘They offer a full laundry service for your entire set of bedsheets and towels however often you ask for that to happen.’

‘I don’t know about you, but when I’m at home, I don’t change my bedsheets every second day,’ she added.

‘So one of the little hacks you can do, is hang the “do not disturb sign” on the outside of your door for the entire duration of your stay.’

While some people are tempted to eat and drink to their heart’s content on holiday, Caitlin resists the urge and makes the most out of buying as few meals as possible.

‘At home, I always make sure to keep my leftovers,’ she said.

‘So if possible, I’ll take a container with me so that I can take my leftovers home.

‘That can really help reduce the amount of waste because you’ll be able to eat it for brekkie the next day.’

Caitlin has also managed to cut back on packing as much as possible using a concept dubbed ‘capsule wardrobe’, which involves taking fewer but more versatile clothes.

‘I do almost all of my travelling with carry-on only luggage,’ she said.

‘It means that I’m not taking any extra weight, because each kilo that we add to our baggage increases the overall carbon footprint of our trip.

‘So that pair of jeans goes from being your day-time walking around jeans with a T-shirt to your nighttime jeans with a cute, little fancy top.’

In 2017, she managed to travel from New Zealand to the UK, Scandinavia, Iceland, Canada and the United States with just a carry-on bag weighing less than 10 kilos.

Caitlin also calls ahead to ask for hotels to remove any complimentary bathroom ‘small bottle’ products including shower gel, shampoo and conditioner.

‘Send a message beforehand saying “please don’t do that, I’m going to bring my own solid bar of shampoo, conditioner and toothpaste”.

‘I don’t need the small plastic bottles that are going to end up going through recycling or more likely to landfill.’

She also travels with a spoon and chopsticks to avoid having to use disposable cutlery when ordering takeaways.

‘That’s one more fork that won’t go to landfill,’ she said.

‘A pair of chopsticks and a spoon will get through all airport security and are light to carry.

‘Bringing a knife – that will get confiscated, guaranteed.

‘Even if you find yourself parked by the side of the road in the middle of the Canadian Rockies trying to cook on the tiniest gas cooker you’ve ever seen, you will be able to do anything with chopsticks and a spoon.’

Demand for international travel in 2022 bounced back to 80 per cent of the pre-pandemic level, reaching 800 megatonnes of CO2, according to the International Energy Agency.

A single person flying from London to Athens and back generates an estimated 0.873t of CO2, according to myclimate’s flight calculator.

Part of the problem, says Caitlin, is that aviation companies receive large subsidies from the government, which means the price of a plane ticket is often lower than that of trains, boats or even buses.

The couple still have to occasionally use planes for work, but try to avoid them at all costs.

‘It’s all about balance and what’s sustainable for you,’ she said.

‘Transport is usually the biggest carbon emitter of our holidays, and some methods of transport are well known to be bigger fuel burners than others.

‘Aeroplanes and cruise ships are the big two to try and reduce or avoid entirely.’
