Paper
A decree from the University president dated 28 November 2011 stipulates a uniform standard for the use of recycled paper. Aside from a few exceptions (e.g., special occasions, certificates, and contracts), you must order recycled paper with a quality of 90% whiteness due to its visual appeal via the framework agreement of Hamburg’s Ministry of Finance. This helps significantly decrease electricity and water consumption in paper production and further reduce costs by 3% compared to ordering virgin fiber paper.
Nonetheless, you are free to use recycled paper with a lower degree of whiteness, which is less damaging to the environment.
