2026 Sierra Club Engagement Calendar

Great care and only top-quality materials go into the production of this exceptional Sierra Club engagement calendar, recently updated to be more environmentally friendly, with no individual plastic wrapping. The deluxe wire-o binding allows it to lie flat on your desk, and the photos and grids are printed on elemental chlorine free, Forest Stewardship Council®–certified paper containing a minimum of 60 percent pre and postconsumer waste. FSC® certification guarantees that the virgin component of the paper has been sourced from forests managed in an environmentally and socially responsible manner.
