Helping to mitigate climate change
Forests absorb CO2 and help to conserve the environment
Maintaining Group-owned forests and keeping them in good health also helps to protect the global environment for the future.
More than 20,000 metric tons of CO2 are absorbed each year
Forests help to mitigate climate change by absorbing CO2 and supplying the oxygen that we and other living organisms need to live. Forests owned by the Mitsui Fudosan Group absorb and store 21,315 metric tons of CO2 per year (this number is certified by the FORESTOCK Association as of January 1, 2023). The average household in Japan emits 2.88 metric tons of CO2 per year (Ministry of the Environment, 2020), so this is equivalent to 7,400 households.
Planned growth cycles further prevent global warming
Forest regeneration helps to further mitigate climate change.
As shown in the graph below, trees absorb more CO2 when they are between six and 55 years old.

As shown in the graph below, many of the trees in the Mitsui Fudosan Group’s forests are between 45 and 55 years old, which is generally a suitable age for felling. Therefore, the amount of CO2 these forests absorb can be increased through planned cycles to create “never-ending forests.”
