Trees bring real benefits to our cities, our health and our wellbeing. Each year London’s trees remove 2.4 million tonnes of air pollution, including carbon dioxide, dust and other gaseous toxins. Trees are vital to our ecosystem and prevent premature deaths caused by airborne pollutants.
The effects of climate change are already being felt. We’re experiencing warmer, wetter winters, and hotter, drier summers, creating higher temperatures in our cities. Climate change has caused an increase in pests and disease, which had never previously affected the UK. The impact has been an unprecedented threat to some iconic tree species, including ash, horse chestnut and oak.
By planting 75,000 urban trees worldwide each year, Trees for Cities is building resilience against threats facing the natural environment. Planting a range of tree species enhances structural and functional diversity in woodlands and on city streets, as well as building resistance to pests and disease.
