Our Positive Impact
Every book that finds a second home on BookSwap is one fewer printed, shipped, and discarded.
Our Purpose & Mission
Our purpose is to amplify the transformative power of reading — because books change lives, and access to them should not depend on your budget.
Our mission is to make reading more accessible and affordable through book reuse. Every swap extends the life of a book, puts it in the hands of someone new, and keeps it out of the bin.
Two Pillars of Impact
Planet
At the heart of the circular economy
A locally swapped book generates zero packaging waste — no bubble wrap, no cardboard, no plastic film. BookSwap keeps books moving through dozens of readers across Switzerland rather than gathering dust or ending up in a landfill.
Lower the carbon footprint of reading by extending the life of books and reducing the need for new production and distribution.
Reduce book waste by keeping used books in active circulation and out of landfill, incineration, or recycling.
People
Foundation for societal sustainability
Money stays local. Swaps between Swiss residents keep value in the community — while putting more books into more hands at a price that works for everyone.
Democratize access to reading by making books available to more people, regardless of socio-economic background.
Strengthen community by fostering inclusion, trust, and solidarity among readers.
Support the development of a more informed, open-minded, and critical-thinking society.
Every Swapped Book Saves
1.5 kg
CO₂ not emitted
Paperback production emits ~1.5 kg of CO₂ through manufacturing, printing, and distribution. Buying second-hand means all of that already happened — your purchase adds nothing new.

~30 L
of water saved
Paper manufacturing is water-intensive. A typical paperback uses ~300 g of paper, which requires roughly 30 litres of process water to produce — all avoided when you buy second-hand.

1/60th
of a tree per book
One tree yields enough paper for about 60 paperbacks. Each second-hand book chosen over new spares roughly 1/60th of a tree from being cut down — small per book, significant at scale.

No ship
emissions when local
Local pickup eliminates packaging waste and last-mile delivery emissions entirely. Any short personal trip to exchange a book is a fraction of postal shipping — and is often combined with other journeys.

Our Sustainable Approach
We hold no physical inventory, run no warehouses, and ship nothing ourselves. Every transaction on BookSwap happens between two people — we are simply the connection.
We will always promote local pickup over shipping, second-hand over new, and community exchange over consumption.
The technology behind BookSwap
~0.15 g
CO₂ per page view
Serverless architecture scales to zero when idle — no always-on compute, no wasted energy.
500×
positive return
Each transaction costs ~2–3 g CO₂ to facilitate, yet saves ~1,500 g by avoiding a new book.
100%
renewable-backed
Our infrastructure runs on Vercel and Supabase (AWS Frankfurt), both backed by renewable energy certificates.
