Carbon Footprint chiratidzo chinoyera kukanganisa kwezviitwa zvevanhu pane zvakatipoteredza. Pfungwa ye "carbon footprint" inotangira kubva ku "ecological footprint", inonyanya kuratidzwa se CO2 yakaenzana (CO2eq), iyo inomiririra yakazara greenhouse gasi rinobudiswa panguva yekugadzirwa kwevanhu uye kushandiswa kwemabasa.
Carbon footprint iko kushandiswa kweHupenyu Cycle Assessment (LCA) kuongorora kuburitswa kwegasi regreenhouse zvakananga kana zvisina kunanga nechinhu chekutsvagisa mukati mehupenyu hwayo. Pachinhu chimwe chete, kuoma uye kuwanda kwekabhoni footprint accounting yakakura kudarika kabhoni emissions, uye mhedzisiro yeaccounting ine ruzivo nezve kabhoni emissions.
Nekuwedzera kuoma kwekushanduka kwemamiriro ekunze epasirese uye nenyaya dzezvakatipoteredza, kabhoni footprint accounting yave yakakosha. Izvo hazvigone kutibatsira chete kunyatsonzwisisa kukanganisa kwezviitwa zvevanhu pane zvakatipoteredza, asi zvakare kupa hwaro hwesainzi hwekugadzira nzira dzekudzikisa emission uye kukurudzira shanduko yegirinhi uye yakaderera-kabhoni.
Hupenyu hwese kutenderera kwe bamboo, kubva pakukura nekusimudzira, kukohwa, kugadzirisa uye kugadzira, kushandiswa kwechigadzirwa kusvika pakurasa, ndiyo yakazara maitiro ekabhoni kutenderera, kusanganisira bamboo sango kabhoni sink, bamboo chigadzirwa uye kushandiswa, uye kabhoni tsoka mushure mekuraswa.
Chirevo chekutsvagisa ichi chinoedza kuratidza kukosha kwekudyara masango ecological bamboo uye kusimudzira maindasitiri ekugadzirisa mamiriro ekunze kuburikidza nekuongorora kwekabhoni tsoka uye ruzivo rwekunyora kabhoni, pamwe nehurongwa hwechigadzirwa chiripo che bamboo kabhoni tsoka yetsvakiridzo.
1. Carbon footprint accounting
① Pfungwa: Zvinoenderana netsanangudzo yeUnited Nations Framework Convention on Climate Change, kabhoni footprint inoreva huwandu hwekabhoni dhaikisaidhi nemamwe magasi egreenhouse anoburitswa panguva yezviitwa zvevanhu kana kuunganidzwa mukati mehupenyu hwese hwechigadzirwa/sevhisi.
Carbon label "chiratidzo che" chigadzirwa kabhoni footprint ", inova yedhijitari inoratidzira kutenderera kwehupenyu kuzere greenhouse gasi kuburitswa kwechigadzirwa kubva kune yakabikwa kusvika mukurasa kudzoreredzwa, ichipa vashandisi ruzivo nezve chigadzirwa chinoburitsa kabhoni nenzira ye label.
Hupenyu cycle assessment (LCA) inzira itsva yekuongorora nharaunda yakagadziridzwa munyika dzekuMadokero mumakore achangopfuura uye ichiri muchikamu chekuenderera mberi kwekutsvaga nekusimudzira. Iyo yakakosha chiyero chekuongorora chigadzirwa kabhoni tsoka ndiyo nzira yeLCA, iyo inoonekwa seyakanakisa sarudzo yekuvandudza kuvimbika uye nyore kwekabhoni tsoka yekuverenga kuverenga.
LCA inotanga yaona uye kuverengera mashandisirwo esimba nezvinhu, pamwe nekuburitswa kwezvakatipoteredza mukati menguva yese yehupenyu, yobva yaongorora mabatiro ekushandiswa uku nekuburitswa pane zvakatipoteredza, uye pakupedzisira inozivisa nekuongorora mikana yekudzikisa izvi zvinokanganisa. Iyo ISO 14040 yakajairwa, yakapihwa muna 2006, inokamura "matanho ekuongorora kutenderera kwehupenyu" mumatanho mana: kutsunga kwechinangwa uye chiyero, ongororo yezvinyorwa, kuongororwa kwemhedzisiro, uye kududzira.
② Zviyero uye Nzira:
Pane nzira dzakasiyana dzekuverenga kabhoni tsoka parizvino.
MuChina, nzira dze accounting dzinogona kupatsanurwa muzvikamu zvitatu zvichienderana nesystem boundary settings uye modhi misimboti: process based Life Cycle Assessment (PLCA), Input Output Life Cycle Assessment (I-OLCA), uye Hybrid Life Cycle Assessment (HLCA). Parizvino, pane kushomeka kweiyo yakabatana yenyika zviyero zvekabhoni footprint accounting muChina.
Pasi rose, kune matatu makuru epasi rose zviyero padanho rechigadzirwa: "PAS 2050: 2011 Tsanangudzo yeKuongororwa kweGreenhouse Gas Emissions panguva yeChigadzirwa uye Sevhisi Hupenyu Cycle" (BSI., 2011), "GHGP Protocol" (WRI, WBCSD, 2011), uye “ISO 14067:2018 Greenhouse Gases – Product Carbon Footprint – Quantitative Requirements and Guidelines” (ISO, 2018).
Zvinoenderana neiyo lifecycle dzidziso, PAS2050 uye ISO14067 pari zvino yakadzikwa zviyero zvekuongorora chigadzirwa kabhoni tsoka nenzira dzinowanikwa pachena dzekuverenga, ese anosanganisira nzira mbiri dzekuongorora: Bhizinesi kune Mutengi (B2C) uye Bhizinesi kune Bhizinesi (B2B).
Izvo zvekuongorora zvemukati zveB2C zvinosanganisira zvigadzirwa, kugadzira uye kugadzirisa, kugovera uye kutengesa, kushandiswa kwevatengi, kuraswa kwekupedzisira kana kudzokorodza, kureva, "kubva paucheche kusvika kuguva". Iyo B2B yekuongorora yemukati inosanganisira mbishi zvinhu, kugadzira uye kugadzirisa, uye kutakura kuenda kuzasi kwevatengesi, ndiko kuti, "kubva pamubhedha kuenda kugedhi".
Iyo PAS2050 chigadzirwa kabhoni footprint certification process ine matanho matatu: yekutanga nhanho, chigadzirwa kabhoni tsoka tsoka yekuverenga nhanho, uye anotevera matanho. Iyo ISO14067 chigadzirwa kabhoni footprint accounting process inosanganisira nhanho shanu: kutsanangudza chigadzirwa chakanangana, kutarisa accounting system muganho, kutsanangura muganho wenguva yekuverengera, kugadzirisa emissions mukati memuganho wesystem, uye kuverenga chigadzirwa kabhoni tsoka.
③ Zvinoreva
Nekuzvidavirira kune kabhoni tsoka, tinogona kuona nzvimbo dzakakura dzekuburitsa uye nzvimbo, uye totora matanho anoenderana kuderedza kuburitswa. Kuverenga carbon footprint kunogonawo kutitungamirira kuti tigadzire mararamiro e-low-carbon mararamiro uye maitiro ekushandisa.
Carbon labeling inzira yakakosha yekuburitsa greenhouse gasi munzvimbo yekugadzira kana lifecycle yezvigadzirwa, pamwe nehwindo revanoisa mari, masangano anodzora ehurumende, uye veruzhinji kuti vanzwisise kuburitswa kwegasi regreenhouse remakambani ekugadzira. Carbon labeling, senzira yakakosha yekuburitsa ruzivo rwekabhoni, yave kugamuchirwa zvakanyanya nenyika zhinji.
Agricultural product carbon labeling ndiko kushandiswa chaiko kwekabhoni kunyora pazvigadzirwa zvekurima. Kuenzaniswa nemamwe marudzi ezvigadzirwa, kuiswa kwekabhoni zvinyorwa muzvigadzirwa zvekurima kunonyanya kukurumidza. Chekutanga, zvekurima ndiko kwakakosha kuburitsa gasi regreenhouse uye hombe sosi yekuburitsa isiri carbon dioxide greenhouse gasi. Kechipiri, kana zvichienzaniswa neindasitiri yeindasitiri, kuburitswa kweruzivo rwekabhoni mukugadzirwa kwekurima hakusati kwapera, izvo zvinotadzisa kupfuma kwemamiriro ekushandisa. Chechitatu, vatengi vanoona zvichinetsa kuwana ruzivo runoshanda pane kabhoni tsoka yezvigadzirwa pamagumo evatengi. Mumakore achangopfuura, nhevedzano yezvidzidzo zvakaratidza kuti chaivo mapoka evatengi anoda kubhadhara kune yakaderera-kabhoni zvigadzirwa, uye kabhoni labeling inogona kunyatso kutsiva iyo asymmetry yeruzivo pakati pevagadziri nevatengi, zvichibatsira kuvandudza kushanda kwemusika.
