carbon sequestration potential of different tree species  


Contactez-nous

It illustrates how each type of tree, including Paulownia, compares in terms of the maximum amount of CO2 they can sequester. As shown, Paulownia stands out due to its exceptionally high sequestration capability. ​

Paulownia is often cited as one of the fastest-growing trees, which gives it an exceptional ability to sequester carbon. Due to its rapid growth, Paulownia can sequester carbon at a much higher rate than many other trees. Estimates vary, but it is generally accepted that Paulownia can sequester up to 10 tons of CO2 per hectare per year under optimal conditions.

To put this in perspective with the other trees listed previously over a period of 10 years:

  • Paulownia: Up to 100 tons of CO2 (10 tons per year over 10 years)

This high capacity positions it as a leading candidate for reforestation projects focused on combating climate change and carbon offsetting.

Here are the estimated amounts of CO2 that each type of tree can sequester over a 10-year cycle:

  • Paulownia: Up to 100 tons of CO2 (10 tons per year over 10 years)
  • Douglas Fir: Approximately 7.5 tons of CO2
  • Sitka Spruce: Approximately 7 tons of CO2
  • Norway Spruce: Approximately 6.5 tons of CO2
  • Western Red Cedar: Approximately 8 tons of CO2
  • Silver Maple: Approximately 5.5 tons of CO2
  • American Sycamore: Approximately 4.8 tons of CO2
  • Red Oak: Approximately 6 tons of CO2
  • Black Walnut: Approximately 5 tons of CO2
  • Sugar Maple: Approximately 5.2 tons of CO2
  • American Elm: Approximately 4.5 tons of CO2


A

  • Douglas Fir: Known for its longevity and robust growth, especially in urban environments where it also helps absorb pollutants like sulfur dioxide and nitrogen oxides.
  • Sitka Spruce: Thrives in cool, wet climates of northern regions and supports dense forest ecosystems that are effective at carbon sequestration.
  • Norway Spruce: Grows quickly and starts sequestering carbon effectively early in its life cycle.
  • Western Red Cedar: Known for its size and longevity, capable of capturing significant amounts of carbon over its potentially millennium-long lifespan.
  • Silver Maple: Fast-growing and capable of significant carbon sequestration over its lifetime.
  • American Sycamore: Known for its rapid growth and early life carbon capture efficiency.
  • Red Oak: Offers substantial carbon sequestration capability due to its large size and extensive root systems that mirror its above-ground branch structure.
  • Black Walnut: Recognized for its leaf structure which maximizes carbon absorption.
  • Sugar Maple: Particularly valuable in urban settings for its carbon sequestration capabilities.
  • American Elm: Known for its dense leaf growth that maximizes carbon capture, making a comeback with disease-resistant varieties.
