No matter where in the world the trees featured in this vibrant nature calendar stand, one would be tempted to look into their trunks to count the growth rings and learn more about their long lives. The forest through the changing seasons, gnarled roots, gigantic treetops, and branches that tirelessly reach for the light serve as a beautiful reminder that even slow growth leads to remarkable strength. Like all Ackermann calendars, this one is printed exclusively in Germany on paper sourced from exemplary managed, FSC®-certified forests and other controlled sources. Transparent CO2 compensation is carried out in cooperation with our climate partner NatureOffice, which demonstrably reduces greenhouse gases while promoting the local environment and the interests of the community.
