The Post Office launched the « For the planet » eco-friendly stamp book at the beginning of 2007. This book of 12 stamps replaced the book of 10 stamps and is almost the same size. This operation saves 12 tons of paper a year; this is the equivalent of 192 trees. The unbleached kraft paper comes from sustainable forests. The glue is solvent-free and water-based.
