What is better: European or Tropical Forest ?
Forests should be planted wherever it is necessary and wherever it is possible. Tropical forests absorb more CO^₂ because the trees grow all year long. That said, a forest in Europe will grow for longer. There are also differences in the price; these can be seen between projects and between geographical regions. When Trees for Travel began, the cost to absorb one tonne of CO^₂ in a Dutch forest was five times higher than in an East European forest and ten times than in a tropical forest. By spreading our forestry projects over various continents, our costs are a little higher but at the same time the risk is spread.

Can the forest be commercially exploited?
Products can be removed from the forest, as long as this occurs in a sustainable manner that does not damage the forest. Harvesting of bamboo, nuts, fruits, and brushwood does not damage the forest and in theory, neither does removal of wood for furniture or construction: This wood will stay intact for a long time (therefore locking up its CO^₂). If the surrounding forest is not damaged and renewed planting occurs, extra CO^₂ may even be absorbed.
