When we’ve traveled, we’ve seen how different parts of the world deal with sustainability, eco-friendly products and waste, and it makes us want to work harder toward the goal of traveling “greenly.” The next time you’re preparing for your trip, consider how you can make a positive impact while traveling.

Through the years traveling as a couple, and due to much trial, error and learning, we now have a list of things we do to make a trip sustainable. We’ve found that traveling sustainably together has also helped us stay healthy together and save money in the long term.

These tips might be habits we’ve formed of using some durable products in order to limit use of disposable products, or habits we’re able to have due to the availability of new inventions, like travel apps recently. We’ve also taken note of how people in different cultures use energy, save energy, shop and store food.

Here are the things we do, whenever possible, during our trips to do our part in saving the environment. Have you used any of our “green travel” trips below?

We ditch plastic produce bags and use reusable produce bags.

When I met Dan, I saw that in grocery stores, he would skip plastic produce bags (the kind that you tear off from a roll) and put fruits or vegetables directly into his shopping cart. I realized how many plastic bags he was saving by doing this, and I started doing it, too.

If you want to avoid plastic and save plastic during your shopping trips, you can either skip the plastic bags on rolls at your supermarket, or use these reusable produce bags so that your onions, apples or cloves of garlic don’t float around your shopping cart.

These reusable bags are a great product to have with you, whether home or abroad, and they fold up small!

We use our travel Tupperware or containers to avoid use of disposable snack bags.

Gone are the days when we take snacks in disposable plastic baggies. In Peru and Colombia, we developed a collection of plastic containers from grocery store items (like dried fruit or nuts) and used these as our lunch bowls, snack containers and more.

If you’d like to have durable, leak-proof and smart travel containers for food, try these Rubbermaid containers, which are a great way to store bite-size food during a long day of transport or a hike.

We like to cut up local produce and snack on it when we get to the viewpoint of a trail. We’ll bring cucumbers, tomatoes, carrot sticks, berries, orange slices or olives in our travel containers, and when we eat everything out of them, we stack them and wrap them in a bag.

Save plastic bottles and use a trusty reusable water bottle for travel.

Life changes for the better when you travel with a water bottle that you can trust. Both Dan and I are big fans of our current bottles, and we look for different features in both.

Dan uses the YETI Rambler 26 oz Bottle and he likes the puncture-resistant kitchen-grade stainless steel look with an extra-wide mouth opening. It’s dishwasher-safe, and the leak-proof cap has a three-finger grip on top.

I use the 15 oz S’ip Stainless Steel Water Bottle. It is vacuum-insulated, double-walled and has a narrow mouth, which is my preference for style. I like the slim style and the way it fits into a mesh pocket of my daypack.

I can’t believe I used to travel without a stainless steel water bottle, but I am glad I found one I now love and can’t function without. I can’t imagine how many plastic bottles Dan and I have saved over the years by filling our bottles at water coolers and fountains, and by using them for tea, coffee and seltzer.

Use a ride-share app and literally share a ride.

You’ve probably used an app for travel by now. To get around in another country, we like using rideshares for safety, and also in order to pay with credit. When it comes to being environmentally-friendly, the best way to maximize eco-friendliness with these apps is to choose an option like pooling.

In Peru, Colombia and Mexico, we used Uber often to take rides from neighborhood to neighborhood. Choosing options like UberPool allows a driver to pick you up and drop you off with a passenger who’ll take the ride also, because he or she has a similar trajectory. Not only is this a way to save a buck here and there, but in massive cities, this is a way to do our environment a favor and lessen our carbon footprint, if the only way to get somewhere is by car.

Drink your coffee in a ‘real cup.’

Why should you drink your coffee in a mug, and not a throw-away cup made of paper or Styrofoam?

First, every time you use a single-use cup, you’re putting it in the trash after you’re done (you’re probably not reusing Styrofoam or a soggy paper cup the next day, right?). It then becomes waste and gets sent to a dump, and the world already has too much garbage. Use a mug or cup from the cafe, and they’ll be glad you asked.

Second, if you use a mug or glass from the cafe, you can take pretty photos of coffee, and everyone loves pretty photos of coffee! No one ever asked for a Styrofoam cup as a prop in a photo, so next time you’re in a cafe and have time to sit down, ask the barista before he or she pours your drink for a “to-stay” cup.

Then, pose your latte or cold brew with flowers, glasses or a magazine, and voila!

Buy local produce (and stay healthy!).

Lessen your carbon footprint and buy local! It helps out the local economy and local people, and encourages their businesses.

When traveling long-term, we were able to make choices and form habits that aren’t possible when we travel faster and for shorter periods of time. For example, one of our favorite health habits is that we always try to stay in accommodation that has a kitchen so that we can cook.

When we have the luxury of cooking, it’s then up to us what we choose to buy to cook. When shopping in supermarkets and local markets, we consider what’s local (it’ll be freshest and have the smallest carbon footprint) versus what’s imported (more expensive, likely less fresh and a higher carbon footprint).

This was very apparent in Estonia, where the cheapest and most local goods were potatoes, carrots, root vegetables and herbs like dill, and in northern Vietnam, where buying pineapple, onions, sugarcane and bananas was far more affordable (and environmentally-friendly) than purchasing apples imported from New Zealand at $5 or $6 per kilo. The apples example made it most apparent to us about the cost of goods when they’re not local, because, being from the northeast, apples are super cheap when they’re in season during our autumn.

Lastly, buying local produce will introduce you to awesome fruits, vegetables and flavors, like the mamey of Mexico (so creamy), the pitahaya of Colombia (so sweet) and the North Sea fish of Latvia (we don’t have these at home!).

Ask about recycling, if it’s not clear.

In Taipei, we had to get in touch with our Airbnb host’s landlady to have our trash and recycling taken out. Taipei doesn’t have dumpsters or trash disposal areas, and doesn’t have too many public garbage cans at all – this is to make people aware of their waste, and to keep the city clean.

Because our Airbnb did not have a jug water cooler, we bought purified drinking water in the largest amount we could, which was a 6-liter bottle from the convenience store nearby. After a few days, we wanted to recycle our empty jugs, but had no idea where to do it. The landlady was glad to come help us, and we were relieved that our recyclable items were not going to go into the trash. It helps to ask, if you’re unsure!

Ditch the single-use plastic bags in supermarkets, drugstores and convenience stores.

Trade single-use bags for a durable tote bag.

Much of the world is now acknowledging that plastic bags are terrible for our Earth. Many people are trying to minimize their use of them; however, we found that across Asia and Latin America, we would be offered plastic bags at every store, even if we didn’t need one.

For this reason, I usually walk around with a canvas tote bag that I like the look of, like this one. I use it as a purse, as it’s a bag that’s big enough to hold my water bottle, wallet, phone, groceries and any items I pick up to buy during the day. It also helps me say ‘no’ to being given a plastic bag in a store.

Reuse plastic bags if they get wet or dirty by leaving them to dry overnight and use them again.

If you do happen to receive plastic bags, save them and reuse them again and again. We use plastic bags that we always flatten out and bring from home, and use them repetitively for shoes, laundry items, wrapping food and more.

If we’re carrying something and the bags get wet, we leave them out to dry on a door handle overnight and continue to use them in the future. This way, we’re reusing the bags without wasting.

Hang clothes instead of using a dryer.

As Americans, we find out by leaving our home country that the rest of the world doesn’t love dryers like we do. In fact, in a lot of the world, dryers don’t exist! I first found this out when I studied abroad in Hong Kong and the dryers in the washing machine space (which was actually on the roof) didn’t quite work like the ones I knew at home.

When I moved to Shanghai, I didn’t see a dryer for two years! I hardly knew anyone who had one in their home, and I dried my clothes on a rack for the two years I spent in Mainland China.

Having lived in different parts of the world now, Dan and I have seen our share of dryers that work, dryers that half-work and dryers that don’t exist. In the damp winter months of Peru, we luckily had a dryer (drying our jeans otherwise took five days!), but we didn’t have one in Medellin, Colombia. In the Canary Islands, I did various loads of laundry at Nine Coliving and hung every single item on clotheslines in the laundry room and on the laundry lines on the roof. It dried fast, due to the dry climate!

Hanging clothes to dry prevents them from getting fried in a dryer, and also saves heaps of energy. Therefore, we’ve learned to dry only the clothes that would take forever to dry otherwise, and for the rest, we hang them on hangers and drying racks to air dry.

Turn off the water during different parts of your shower.

Going to places like Israel or Cape Town, South Africa, will teach you a whole bit about conserving water. We’re taught to conserve water when we can, but in some places on Earth, conserving water is a very serious topic.

My first time in Israel, we were advised to take short showers and always turn off the sink when brushing our teeth. We were told to never, ever waste water, as it’s a very precious resource in the Middle East – even more precious than at home in the US. In Cape Town, South Africa, any recent visitor to the city will tell you that due to a recent water crisis, showers were cut down to 90 seconds. This’ll teach you FAST how to conserve water while bathing!

It’s lessons like these that teach you how little water you really need to do everyday chores and tasks, and how much you can save. I’m glad I’ve left home to see how the rest of the world saves water, so that I can remember how to save water, too.

Turn your disposable silverware into use-again silverware.

I feel like Mary Poppins when I take various odds and ends out of my bag like plastic spoons when someone else least expects it, but I enjoy being prepared. I also enjoy making multiple uses out of things that are otherwise single-use and considered to be disposable. If we use a plastic spoon every day of the year and throw it out every time, that’s 365 thrown-away spoons!

To avoid this, if you have durable plastic silverware, wash it like it’s real silverware, and use it again! You can keep plastic spoons, forks and knives in your backpack or purse (for that time when you get street food and need an eating utensil) and always be prepared, while also reusing plastic products.

Always turn off the AC, heat, fan and light when you leave your accommodation.

I grew up being taught to be conscious of turning off appliances and lights when I left a room. After I began traveling, I learned that some places, for example, my college dormitory in Hong Kong and a recent hotel in Vietnam, give you a way to conserve energy when you leave a room.

In Asia, it can be common to be given a card to pop into a slot in your hotel, hostel or Airbnb. The slot in which you’ll put it is linked to all the electricity in the room and makes it able to be turned on.

When you leave the room, you take the card with you (sometimes it’s the room key) and that way, you’re unable to use power while you’re out of the room. It’s a great way to save energy and power.

Even if you are not working with a card and slot scenario, be mindful of turning off A/C, heat, lights and fans when you leave your accommodation or any other type of room you’ve been in. This helps avoid overuse and your host will always be thankful for your habits.

Travel more slowly.

Sure, we all want to see as much as possible when we travel. It can be tiring, and we feel like we have to “pack it in.” For one thing, staying somewhere longer can snag you discounts, like staying in an Airbnb for more than two weeks and getting a percentage discounted from the total cost.

In terms of being eco-friendly, the fewer private rides, bus trips and flights you take over a very short period of time… the better! We’ve learned to enjoy and get to really know a place, rather than zipping from city to city every 36 hours, which is taxing on our wallets, our sleep schedules and also, the environment.
