The Challenge is a call to action for landscape architects, municipalities, property owners, developers, and associated professionals around the world to reduce carbon footprints and increase carbon sequestration.

The goal is for all landscape architecture projects going forward to collectively sequester more CO2 than they emit by 2030, with a target of removing one gigaton of CO2 from the atmosphere by 2050.

The initiative is led by Pamela Conrad, Principal at CMG Landscape Architecture and developed through the Landscape Architecture Foundation (LAF) Fellowship for Innovation and Leadership in collaboration with Atelier Ten.
