A single round-trip flight from London to Bangkok releases roughly two tonnes of carbon dioxide — about as much as the average person in Kenya emits over four years. Book that trip, and the airline’s checkout page will cheerfully offer to “offset” it for the price of a sandwich. Whether that sandwich-sized payment accomplishes anything is where the climate travel conversation gets genuinely interesting.
The Offset Skeptics Have a Point
A growing camp of researchers and climate journalists argues that offsets function mostly as a permission slip. Many cheap credits fund tree-planting projects that burn, get logged, or never sequester the carbon promised. At a few dollars per tonne, they bear no resemblance to the real cost of carbon removal, which now runs into the hundreds per tonne. This school’s conclusion is blunt: the only honest carbon offset is a flight you didn’t take. Fly less, stay longer, and treat offsets as a last resort rather than a licence.
The Regenerative School: Neutrality Is the Floor
Regenerative tourism takes a different starting point. Rather than asking how to cancel out harm, it asks how travel can leave a place measurably better — funding reef restoration, paying local guides above market rates, backing community land trusts. Under this lens, a trip that pays into a verified reforestation cooperative and employs local naturalists does more than one that merely neutralises its emissions. Offsetting becomes the minimum, not the goal.
Where the Two Camps Actually Agree
Strip away the rhetoric and the practical advice converges. Both say fly less often and stay longer when you do. Both favour direct routes, since takeoff burns the most fuel. Both note that business class can triple your personal footprint through sheer floor space. And both insist on verified removal credits rather than vague “avoidance” schemes — look for Gold Standard certification or Verra’s VCS with CCB verification, and check that the provider publishes retired serial numbers you can trace. Crucially, ask whether your airline is buying credits or investing in sustainable aviation fuel, which reduces emissions at the source instead of compensating elsewhere.
The synthesis is straightforward: reduce what you can, pay properly for what you can’t, then add a regenerative contribution on top. That sequence — cut, remove, regenerate — respects the sceptics without abandoning the ambition of the regenerative camp.
Actionable Takeaways
- Cut before you compensate. Choose fewer, longer trips, book direct flights, and fly economy where you can. A tonne not emitted beats a tonne offset.
- Buy removal, not avoidance. Pay for credits verified under Gold Standard or Verra’s CCB standard, and verify the serial numbers are retired. If a credit costs less than a coffee, it isn’t doing the work.
- Add a regenerative layer at your destination. Contribute directly to a local conservation or community-run project, so your money builds something lasting rather than merely cancelling a ledger entry.
