Our commitment to removing carbon from the atmosphere.
1% of every Roamly purchase funds frontier carbon-removal technologies through Stripe Climate. Stay connected on your travels and help fight climate change at the same time.

Our climate commitment
Travel and connectivity have a footprint. Even a digital product like an eSIM exists on top of data centres, networks, and devices powered by energy that's not yet fully clean.
That's why Roamly contributes 1% of every purchase to Stripe Climate. The funds are pooled with thousands of other businesses and routed entirely to next-generation carbon removal — technologies that pull CO₂ out of the atmosphere and store it durably.
What is Stripe Climate?
Stripe Climate is a programme that lets businesses direct a fraction of their revenue to carbon removal. Funds are aggregated and committed to Frontier — an advance market commitment co-founded by Stripe, Alphabet, Shopify, Meta, and McKinsey Sustainability — which buys nearly $1 billion of permanent carbon removal between 2022 and 2030.
Unlike traditional carbon offsets (which usually pay for tree-planting or short-term projects), Frontier funds science-backed companies pulling CO₂ from the air and locking it away for 1,000+ years. The science is hard, the cost curve needs to come down, and early demand from businesses like Roamly is what makes that possible.
The technologies we're backing
Frontier funds a diverse mix of approaches. The science is hard, the cost curve needs to come down, and supporting many paths in parallel is the point.
Direct air capture
Industrial-scale machines pull CO₂ directly from the air. The captured carbon is then injected into basalt rock or sealed in concrete, where it mineralises permanently.
Bio-oil sequestration
Converts agricultural waste into a stable carbon-rich liquid and pumps it deep underground — locking away carbon that plants pulled from the air.
Enhanced rock weathering
Spreads crushed silicate rock on farmland to speed up a natural process that pulls CO₂ from the air over geological timescales.
Ocean alkalinity & mineralisation
Boosts the ocean's natural ability to absorb and lock away atmospheric carbon — using chemistry, kelp, or river-mouth limestone.

Why eSIMs are already lower impact
Choosing an eSIM over a physical SIM card already cuts a meaningful slice of waste from international travel:
No plastic SIM cards
Traditional SIMs are tiny pieces of plastic and silicon. Each one ships individually wrapped in cardboard and plastic packaging.
No physical shipping
An eSIM is a digital file. No couriers, no warehouses, no airfreight to your doorstep before you even leave for your trip.
No retail footprint
No shop visits, no airport SIM kiosks, no back-and-forth to find the right plan. The whole experience happens on your phone.
Reusable on every trip
The eSIM hardware lives on your device for as long as you own it. Each new destination is just a new digital plan, never a new piece of plastic.
Why we care
We started Roamly because international travel should be easy and affordable — but easy and affordable shouldn't mean ignoring the cost we're passing on to the planet.
The 1% commitment is small per transaction, meaningful in aggregate, and pointed at the bottleneck that matters: scaling permanent carbon removal so it's available, affordable, and impactful by the time the world needs it most.
