Users with neon green plant trees on the go and actively support the climate. How? By planting trees: In its average lifespan of 25 years, a tree neutralises around 300 kg of CO₂ in the atmosphere. For example, if you plant 48 trees in one year by paying with your neon card (equivalent to spending 2’000 CHF per month), these trees will neutralise around 14 tonnes of CO₂ over their lifetime, which is more than the average annual emissions per Swiss resident.
