10%.
Off the top.
One per cent of our revenue to each of ten programmes. That's ten per cent in total, built in rather than bolted on, every year whatever the numbers say.
This is not a round-up box at your attendees' checkout. It is not their money.
It is ours. Ten per cent of Presso's own revenue - the 1% we charge you - comes off the top and goes to climate work before it ever touches profit.
You don't opt in. You don't pay extra. Choosing Presso is the whole contribution. It's a tie-breaker, not the pitch.
Events shouldn't cost the planet.
A typical 100-person business event generates around 2.4 tonnes of CO2 before anyone has flown in - the same as 24 return flights from London to New York. The biggest culprits aren't travel; they're the details no one questions: printed brochures, signage that ends up in the bin, the post-event landfill of lanyards and leftover swag.
Presso's browser-based app cuts the downloads, the printed guides and the paper - and we fund real climate work on top. Organisers focus on the event; we make sure it gives back.
Stripe Climate, Ecologi and 1% for the Planet.
Trees for Life, the Million Tree Pledge and the Rainforest Alliance.
WWF, ARCHELON, Save The Bees and Code.org.
Ten programmes, and each one gets its own 1% of our revenue. That's what adds up to 10%. It isn't a single pot they take turns drawing from - so yes, 1% really does go to Stripe Climate, and another 1% to WWF, and so on down the list.
Sustainability isn't a green logo in the footer. It's ten separate 1% commitments, off the top - in good years and lean ones.
When two tools do the same job, the one with the stronger climate posture wins - B Corp or renewable-powered where the premium is reasonable for a team our size.
Better events. Better planet. No compromise.
