Contributions to environmental conservation and community formation through cooperation with communities
DCM Forest Project
Since 2007, DCM has undertaken a tree planting project based in Hokkaido. This contributes to achieving SDGs 13 “Take urgent action to combat climate change and its impacts” and SDGs 15 “Life on land”. Going forward, we shall further increase the scale and roll out tree planting activities all around Japan with the help of employees and their families. This is the DCM Forest Project. DCM has signed afforestation agreements with owners of forests through the national or prefectural government, and undertakes tree planting activities with the support of forestry associations and other such parties.

◆ Amount absorbed so far by a 36-40-year-old cedar plantation and the amount absorbed in a year
The amount of carbon dioxide that trees absorb and accumulate differs from tree to tree. For example, a plantation of 36-40-year-old cedar trees cared for suitably is thought to accumulate around 304tons of carbon dioxide per hectare (the equivalent of about 83tons of carbon) (*1).
And each hectare of a plantation of 36-40-year-old cedar trees is thought to absorb around 8.8 tons of carbon dioxide per year (the equivalent of about 2.4 tons of carbon).
◆ Comparison of amount absorbed by cedar trees and familiar carbon dioxide emissions
The volume of carbon dioxide emitted by a household per year was 3,700kg in 2021 (*2). This is the same as the amount stored by around 12 cedar trees aged between 36 to 40 (*3). And if this volume of emissions is converted into the volume that 36 to 40-year-old cedar trees can absorb over a year, it is the same as 420 cedar trees (*3).
Note 1: Multiplying carbon dioxide by 12/44 gives the volume of carbon

Note 3: If it is assumed that there are 1,000 trees per hectare in cedar tree plantation with 40-year-old trees
