    Trillion Tree Declaration
A Trillion Trees to Fight the Climate Crisis

    We, the signatories, pledge to plant and protect one trillion trees.

    In 2007, the late Wangari Maathai launched the Billion Tree Campaign. So far, 15 billion trees have been planted in 193 countries under the guidance of the UNEP and Plant-for-the-Planet. We honor her achievements by taking the campaign to the next level: The Trillion Tree Campaign.

    Three trillion trees currently exist globally (1). The world has space for up to 600 billion mature trees (2) without competing with agricultural lands. To restore these trees, we need to plant at least a trillion trees, since some will not survive. Additionally, we must protect the 170 billion trees in imminent risk of destruction (3). They are crucial carbon storages and essential ecosystems to protect biodiversity.

    A Trillion Trees could capture 25% of all human-made CO2 emissions (4) and hereby help to keep global temperature rise below the crucial 2°C limit (5). The Trillion Trees do not replace the need to avoid carbon emissions, as agreed in Paris, but are a necessary addition.

    Sustainably managed forests and their wood are valuable resources. The use of local timber in construction substitutes CO2-intensive materials (steel and concrete) and the timber continues to store the carbon captured by the tree. Massive afforestation and the resulting timber industry can create hundreds of millions of additional jobs and wealth in the global south, thus reducing population growth and migration.

    We, the signatories, will start a positive global chain reaction to fight the climate crisis.

    We will convince wealthy families to join us in planting trees.
    We will motivate companies to take a leading role in reforestation.
    We will mobilize individuals to buy products from carbon neutral companies.
    We will use our public visibility to promote the Trillion Tree Campaign.
