Our 2026 Campaign Calendar is your guide to a year of tree-planting opportunities, each linked to a cause that matters to the planet and to people. Whether you’re a business looking to inspire your team or an individual wanting to contribute, this calendar shows you what’s ahead and how to get involved.
Each celebration is also a chance to build a planting habit in your organization (or personal routine). It is a simple and recurring way to mark environmental and social events with trees and turn impact into a yearly tradition.
