Iciputulwa ca kubalilapo ica 2019 capitilishe ukubomfya[11)} Ukulolesha ku numa pa cifulo ca kabon icafiita mu myeshi mutanda iyapitapo, ukukula kwa fipe fya kupangapanga ilingi line kulacepa, kabili ifintu ifingi ifibi, kabili ifintu ifingi ifibipile ifya mu cifulo ca kushitishishamo. Pa nshi ya maka yabili aya ku mulu, umutembo wafiita uwafiita uwaonaika mu ciputulwa ca kubalilapo ica mwaka wa mwaka uwa mwaka
Pa numa ya kuwa kwa carbon icafiita mu 2018, imitengo tayalinga ukukula na kabili {1 {1 {1 {1 {1 {1 {1 {1 {119, umutengo walicepeleko mu ciputulwa ca kubalilapo ica 2019, ukushala pa6000-6500 yun pa nshita yonse, kabili takwali ukukula kwakulisha nelyo ukuwa mu cifulo ca kushitishamo 8 CT}.
In January and February 2019, due to a sharp decline in the early stage of raw coal tar, the price of raw coal tar rose after that.

From march to June, due to umutengo wa fipe uwakulisha no kucincimusha kwakulisha ukwa carbon, umutengo wa carbon uwafiita walikulile mu cifulo ca kushitishishamo. Nangu cibe fyo, pa mulandu wa kucefyako ukufwaya kwa mu kati, umutengo wa carbon uwafiita walicefiwe nga nshi mu cifulo ca kushitishishamo, kabili ukucimfyanya kwa mutengo ukwacepa mu mutengo wa mu cifulo ca kushitishishamo umutengo wa ca kabon icakulilako ica kabon icafiita[4}}.
