NABU (Naturschutzbund Deutschland e.V.) is the oldest and, with more than 875,000 members and supporters (as of January 2022), the largest environmental association in Germany.

In a joint campaign by NABU and Telefónica, we collected old cell phones, smartphones and tablets, including accessories, in spring 2023 and sent them to NABU Coesfeld. Telefónica donated a fixed sum to NABU for these collected devices and accessories, which went into the NABU Insect Protection Fund.
