Let's skip the part where we pretend flying 8 people to Southeast Asia is good for the environment. It's not. A round-trip flight from New York to Bangkok produces roughly 2.6 tonnes of CO2 per person. Multiply that by 8 and your group just generated more carbon than the average person in many developing countries produces in an entire year.
That's not a reason to stay home. It is a reason to stop pretending that bringing a reusable water bottle makes you a responsible traveler.
The real question is harder and more interesting: given that your group is going to travel, how do you minimize the damage and maximize the good your trip does for the places you visit?
The Big Levers (What Actually Matters)
Most sustainable travel advice focuses on the small stuff -- skip the straw, take shorter showers, reuse your hotel towel. These gestures matter in aggregate, but they're rounding errors compared to three decisions your group makes before you even pack.
Where you fly is your single biggest environmental choice. A direct flight produces 30-50% less carbon than a connecting flight covering the same distance. If your group of 8 books direct instead of connecting through a hub, you've eliminated a significant chunk of emissions without changing anything else about the trip.
The less obvious version: fly to fewer places. A trip with 3 internal flights "to see more of the country" produces dramatically more carbon than spending 10 days in one region and going deep. Your experience is usually better too -- rushing through three cities means you never actually settle into any of them.
Where you stay determines where your money goes. A locally-owned guesthouse typically keeps 60-70% of your spending in the local economy. An international chain hotel keeps roughly 20%. For groups renting apartments, book through local property managers rather than mega-platforms when you can -- the price is often similar, and more money stays in the neighborhood.
What you eat has a bigger footprint than you'd think. Beef-heavy meals carry a carbon cost 5-10x higher than plant-based ones. You don't need to go vegan -- but if your group does "local food night" three times during a week-long trip, eating seasonal dishes from the market, you'll cut your food-related footprint significantly while probably eating better than you would at a chain restaurant.
The Group Advantage Nobody Talks About
Here's something that doesn't get said enough: group travel is inherently more sustainable than solo travel, per person.
Eight people sharing one villa uses less energy than eight hotel rooms. Eight people in one minivan produces fewer emissions than eight taxis. Eight people cooking together in a shared kitchen wastes less food than eight separate restaurant meals.
A group of 8 sharing a large rental car produces about 80% less per-person transport emissions than everyone taking separate ride-shares. Your group trip isn't the environmental problem -- it might actually be part of the solution, at least compared to everyone traveling individually.
Group Tip: Groups also have more economic leverage. Eight people booking a local guide, a local cooking class, or a locally-owned guesthouse represents meaningful revenue for small businesses that might otherwise lose out to international chains. Solo travelers support local businesses too, but groups move the needle faster.
The Honest Tradeoffs
Sustainable travel isn't free, and it isn't always convenient. Here's what the eco-travel content won't tell you:
Trains are better than planes, but not always practical. Taking the train from London to Barcelona sounds great -- it's about 70% less carbon than flying. It also takes 10+ hours and costs roughly the same as a budget flight. For groups on limited vacation time, the train vs. plane decision is genuinely hard. There's no shame in choosing the flight when it means the difference between your trip happening or not.
Carbon offsets are complicated. A round-trip flight from London to Bali costs about $30-45 to offset through a reputable provider. Is that better than nothing? Probably. Is it a real solution? The science is mixed. If your group wants to offset, use a Gold Standard or Verra-certified provider and treat it as a starting point, not absolution.
Overtourism is a real thing your group contributes to. Eight people at a small village temple or a narrow market alley have a real impact on the people who live there. The most sustainable choice is sometimes visiting the second-most-famous version of whatever you want to see. The neighboring town with the same food and half the crowds. Your experience is often better there, too.
4 Things Your Group Can Actually Do
Forget the 50-point sustainability checklist. If your group does these four things, you'll travel more responsibly than the vast majority of tourists:
-
Book direct flights. One fewer connection per person saves your group a meaningful amount of carbon. Compare routes on Vamo to find direct options across your group's departure cities.
-
Stay in locally-owned accommodation. Apartments, riads, guesthouses, pensiones. Your money goes further in the local economy, and your group usually gets more space. It's often cheaper too.
-
Eat local and seasonal. Hit the market, ask your host where they eat, try the dish that only exists in this region. Skip the international chains -- not for moral reasons, but because the local version is almost always better and cheaper.
-
Slow down. Visit fewer places, stay longer. Three days in one city beats one day each in three cities -- for your footprint and for your experience. Check our group-friendly destination picks for cities worth spending real time in.
The Bigger Picture
Group travel at its best creates genuine connection with other places and people, supports local economies, and builds the kind of shared memories that make life richer. At its worst, it's 8 people treating someone else's home like a backdrop for content.
The difference isn't about carrying a metal straw. It's about approaching each destination with the basic respect of a guest -- because that's what you are. Spend your money where it helps the people who live there. Take only what you need. Leave the place no worse than you found it.
Your group doesn't have to be perfect. Nobody is. But 8 people making slightly better choices adds up faster than you'd think.
