This initiative was the first in the country to be managed by a local government. The number of C02 certification certificates issued has risen year on year from 3 in 2007, to 20 in 2008, to 28 in 2009. The first initiative under this system was the establishment of a wood-based biomass mixed incinerator facility at the Sumitomo Osaka Cement Company, Kochi Plant (in Suzaki).
