The Centre for Urban Forestry Research's I-Tree Carbon Calculator (CTCC) manje isikazwelonke. I-CTCC ihlelwe kuspredishithi se-Excel, njengalesi esidala, kodwa manje isihlanganisa izindawo zesimo sezulu zase-US eziyi-16. Le nguqulo ihlanganisa izici ezintsha: izinhlobo zesundu, izici ezikhishwayo kanye nolwazi lwamandla. Manje abasebenzisi ukusuka ogwini baye ogwini bangafaka izinhlobo zezinto eziphilayo, usayizi wesihlahla (ubude obuphakathi kwebele) noma ubudala besihlahla futhi bathole ulwazi ngenani le-biomass nekhabhoni egcinwe esihlahleni, kanye nezinzuzo ezihlobene namaphrojekthi okonga amandla.
Yonke imiphumela isuselwe kudatha yokukhula kwezihlahla evela endaweni ngayinye kwezingu-16 zesimo sezulu. Ukuze ufunde kabanzi noma ulande lolu hlelo lokusebenza, vakashela i-US Forest Service's Iwebhusayithi Yesikhungo Sezinsiza Zokushintsha Kwesimo Sezulu. Imenyu yosizo kanye nohlu lwemibuzo evame ukubuzwa kufakwe ku-inthanethi ne-CTCC. Usizo lobuchwepheshe olwengeziwe luyatholakala nge-imeyili kokuthi psw_cufr@fs.fed.us.
