Promotion of the use of wood in public buildings

In Yokohama City, based on the "Law Concerning the Promotion of Use of Wood in Public Buildings" promulgated in May 2010, the "Policy on Promotion of Use of Wood in Public Buildings in Yokohama City" was formulated in 2014 to promote the use of wood.
In June 2021, the law was revised to the "Law Concerning the Promotion of Use of Wood in Buildings for Contributing to the Realization of a Decarbonized Society," and the scope was expanded to all buildings, including private buildings.
