Adding about 10% more global forest using Empress Splendor trees would offset all of the CO2 generated by human civilization each year. The US and Canada have 3.2 billion acres of forest (1.3 billion hectares).
Empress trees provide hardwood lumber in 7 to 10 years. The World Tree Carbon Offset Program is taking planting the Empress Splendor tree. The Empress tree is a wet wood which makes it naturally fire and insect resistant. It is a non-invasive, hybrid species, that can grow in many parts of the United States and Canada, where its primary use is lumber.
Planting 30% more forests in the US and Canada using Empress Splendor trees would offset all of the global CO2 problem.
