Focus on Climate and Conservation- Kalua Green
The statement also noted that the meeting covered the Green Africa Foundation’s contribution to continental sustainability efforts, including the Green Africa Villages model and the Plant Your Age campaign.
Green also shared his new book, which examines how governments, companies and environmental campaigns measure the results of tree-planting initiatives.

The book argues that we should pay more attention to trees that survive and grow rather than focusing mainly on the number planted.
In the book, Green applies the proposed approach to his own Plant Your Age campaign, which reports an estimated 981 million tree-growing contributions since 2011.
Kalua said the campaign underwent the same assessment he proposes for governments and corporations.
“For years, we have measured our progress by what we plant on the day of planting, not by what is still standing when no one is watching,” Kalua Green said.
He said the book began with an assessment of his own campaign before extending the call for verification to governments and other organizations.
Kenya-Monaco Climate Partnership
Prince Albert II’s relationship with Green spans about two decades. The Prince visited Green Africa Foundation project sites in Kitui in 2010 and wrote the foreword to Green’s earlier book, Green for Life.
The Prince Albert II of Monaco Foundation has programs focused on climate, biodiversity, water and ocean protection.
