He taputapu penapena hiko te taputapu whakawhiti wera e whakahaere ana i te whakawhiti wera i waenga i ngā wai e rua, neke atu rānei, i ngā pāmahana rerekē. Ka whakawhiti i te wera mai i te wai pāmahana teitei ki te wai pāmahana iti iho, kia tae atu ai te pāmahana wai ki te pūnaha tukatuka, kia tutuki ai ngā tohu kua tohua hei whakatutuki i ngā hiahia o ngā āhuatanga tukatuka, ā, i te wā kotahi, ko tētahi o ngā taputapu matua hei whakapai ake i te whai huatanga o te hiko. Neke atu i te 30 ngā ahumahi e uru ana ki te umanga taputapu whakawhiti wera, pērā i te HVAC, te tiaki taiao, te hanga pepa, te kai, te umanga matū, te whakarewa, te maimoatanga hau, te maimoatanga wai me ētahi atu.

E whakaatu ana ngā raraunga ko te rahi o te mākete o te umanga whakawhiti wera o Haina i te tau 2014 tata ki te CNY66 piriona, ko te nuinga i roto i ngā mara o te hinu, te ahumahi matū, te whakarewa, te hiko, te hanga kaipuke, te whakamahana pokapū, te pouaka whakamātao me te hauhautanga, te mīhini, te kai, me ngā rongoā me ētahi atu. I roto i ēnei, ko te umanga petrochemical tonu te mākete nui rawa atu mō te umanga whakawhiti wera, me te rahi o te mākete o te CNY20 piriona, ko te rahi o te mākete whakawhiti wera i te mara whakarewa hiko tata ki te CNY10 piriona, ko te rahi o te mākete whakawhiti wera o te umanga hanga kaipuke neke atu i te CNY7 piriona, ko te rahi o te mākete o ngā whakawhiti wera i te umanga mīhini tata ki te CNY6 piriona, ko te rahi o te mākete o ngā whakawhiti wera i te umanga whakamahana pokapū neke atu i te CNY4 piriona, ā, he mākete anō hoki tō te umanga kai tata ki te CNY4 piriona. Hei tāpiri, ko ngā waka rererangi, ngā taputapu haurua-ira, te mana karihi, ngā tāwhana hau, te whakaputa hiko photovoltaic solar, te pūngao me ētahi atu mara e hiahia ana ki te maha o ngā whakawhiti wera ngaio, ā, ko ēnei mākete tata ki te CNY15 piriona.

Kua tutuki i te umanga taputapu whakawhiti wera ngā whakatutukitanga whakamiharo i roto i te rangahau mō te tiaki pūngao me te tiaki taiao, te whakapai ake i te pai o te whakawhiti wera, te whakaiti i te hekenga pēhanga, te penapena utu, me te whakapai ake i te kaha wera o ngā taputapu me ētahi atu. Ka mau tonu te tipu pumau o te umanga whakawhiti wera i roto i te wā e whai ake nei, ka mau tonu te tere tipu ā-tau toharite o te 10% mai i te tau 2015 ki te 2025.
