With every purchase of Robert Marc Lehmann's calendar, one square meter of old-growth forest is protected forever! With the new edition of the calendar for 2026, Robert is working together with myMerch, the store through which Robert's products are sold, to protect endangered rainforests: 50% of the amount donated comes directly from myMerch.
The calendar contains a QR code with which you can directly view the piece of forest protected by you and many others. You can download the certificates of the donation from myMerch below.
