Trees are a powerful ally in combating climate change. By capturing carbon, cooling the planet, and supporting ecosystems, they play a vital role in preserving the Earth's future.
Trees and climate action
Carbon capture and storage
- Natural Carbon Sinks: Forests absorb around 2 billion tonnes of CO2 annually, offsetting 1/3 of emissions from fossil fuels.
- Preventing Emissions: Protecting forests prevents the release of stored CO2, which accounts for 18% of global emissions—more than the transport sector.
Cooling the planet
- Trees cool the air by providing shade and releasing water through transpiration, reducing urban heat and combating rising global temperatures.
Protecting ecosystems
- Forests house 80% of terrestrial biodiversity, supporting wildlife that is essential for healthy ecosystems.
- Preventing deforestation helps avoid the extinction of up to 100 species daily.
Social benefits of planting trees
Health and well-being
- Access to green spaces and trees reduces stress, boosts mental health, and improves overall well-being for individuals and communities.
- Many medicines are derived from trees, offering valuable resources for healthcare.
Community support
- Forests provide food, materials, and income for millions, particularly in rural and developing regions, where up to 28% of household earnings can come from forest resources.
- Trees also enhance community resilience by reducing risks of flooding and soil erosion.
Planting trees: A simple solution with a big impact
Planting trees is one of the most effective ways to combat climate change while improving social and environmental well-being. Every tree planted absorbs carbon, supports biodiversity, and strengthens communities. Together, we can grow a greener, healthier, and more sustainable world.
