The Center for Urban Forestry Research's Tree Carbon Calculator (CTCC) yava yenyika. Iyo CTCC yakarongwa muExcel spreadsheet, sezvakangoita yekare, asi ikozvino inovhara 16 US mamiriro ekunze. Iyi vhezheni inosanganisira zvinhu zvitsva: mhando yemichindwe, emissions zvinhu uye ruzivo rwesimba. Iye zvino vashandisi kubva kumahombekombe kuenda kumahombekombe vanogona kupinda mumhando, saizi yemuti (diameter-at-breast urefu) kana zera remuti uye vanogamuchira ruzivo pamusoro pehuwandu hwebiomass uye kabhoni yakachengetwa mumuti, pamwe nemabhenefiti ane chekuita nemapurojekiti ekuchengetedza simba.
Mhedzisiro yese yakavakirwa pakukura kwemuti data kubva kune imwe neimwe ye16 mamiriro ekunze. Kuti udzidze zvakawanda kana kudhawunirodha iyi application, shanyira iyo US Forest Service's Climate Change Resource Center webhusaiti. Menyu yekubatsira uye rondedzero yemibvunzo inowanzo bvunzwa inosanganisirwa online neCTCC. Rumwe rubatsiro rwehunyanzvi runowanikwa kuburikidza neemail pa psw_cufr@fs.fed.us.
