Iyi i…”yakadzama”… chinyorwa chebhasikoro |EWIG

Pose paunotarisana nekuzara kwemotokari mangwanani nemanheru munguva dzekumhanya-mhanya, uri kufunga kuti zvingava nani here kana vanhu vakawanda vakachovha mabhasikoro kuenda kubasa?"Zvakanaka, zviri nani?"Nyika zhinji dzakavimbisa zviri pamutemo kuwana zero net kabhoni emissions panosvika 2050, uye UK imwe yacho.

Kunyange zvazvo takafambira mberi mune dzimwe nzvimbo, utsi hunobva muzvifambiso huri kuramba huchikwira.Kana tikasachinja nzira muhupenyu hwedu, hatigone kusvika net zero.Saka, kuchovha bhasikoro chikamu chemhinduro here?

Kuti tinzwisise zvinogona kuitika pakuchovha bhasikoro pane remangwana rakagadzikana, tinofanira kupindura mibvunzo miviri yakakosha:

1. Ndeipi mutengo wekabhoni wekuchovha bhasikoro?Inofananidzwa sei nedzimwe nzira dzekufambisa?

2. Ko kuwedzera kunoshamisa kwekuchovha bhasikoro kuchava nerubatsiro pane yedu kabhoni tsoka?

Chidzidzo ichi chakawana kuti kabhoni tsoka yebhasikoro ingangoita magiramu makumi maviri nerimwe ecarbon dioxide pakiromita.Izvi zvishoma pane kufamba kana kutora bhazi, uye mhepo inobuda isingasviki chikamu chimwe mugumi chekutyaira.

Zvinenge zvikamu zvitatu kubva muzvina zvemabhasikoro greenhouse gasi zvinobuda kana chimwe chikafu chinodiwa kugadzira mabhasikoro e "fuel", mamwe acho anobva mukugadzira mabhasikoro.

Iyo kabhoni tsoka yemabhasikoro emagetsiyakatodzika kupfuura iyo yemabhasikoro echinyakare nekuti kunyangwe kugadzira mabhatiri uye kushandisa magetsi kuburitsa kubuda, vanopisa mashoma macalorie pakiromita.

Carbon fiber gomo bhasikoro

Ko bhasikoro rine hushamwari zvakadii senzira yekufambisa?

Kuti uenzanise kuburitsa kwecarbon fiber bhasikorouye dzimwe mota, isu tinofanirwa kuverenga huwandu hwese hwekubuda gasi regreenhouse pakiromita.

Izvi zvinoda kuongororwa kutenderera kwehupenyu.Hupenyu kutenderera ongororo inoshandiswa kuenzanisa kuburitswa kwezvakasiyana zvigadzirwa, kubva kumagetsi zvidyarwa kuenda kumitambo yemitambo.

Chirevo chavo chekushanda ndechekuwedzera zvese zvinoburitsa mukati mehupenyu hwese hwechigadzirwa (kugadzira, kushanda, kugadzirisa, uye kuraswa) uye kupatsanura neiyo inobatsira inobuda iyo chigadzirwa chinogona kupa mukati mehupenyu hwacho.

Kune chiteshi chemagetsi, kubuda uku kunogona kunge kuri huwandu hwesimba remagetsi rainoburitsa mukati mehupenyu hwayo;kumota kana bhasikoro, inhamba yemakiromita afambwa.Kuti uverenge kuburitsa pakiromita yemabhasikoro kuenzanisa nedzimwe nzira dzekufambisa, isu tinofanirwa kuziva:

Greenhouse gasi emissions ine chekuita nekugadzira mabhasikorouye kugadzirisa.Zvadaro patsanura nehuwandu hwehuwandu hwemakiromita pakati pekugadzirwa nekugadzirisa.

Hutsi hunogadzirwa nechikafu chekuwedzera chinogadzirwa pakiromita chinopa mafuta kune vanochovha mabhasikoro.Izvi zvinoitwa nekuverenga mamwe macalorie anodiwa pakiromita kutenderera uye kuawanza neavhareji yekugadzirwa kwechikafu kuburitsa pacalorie inogadzirwa.

Zvakakosha kubvuma kuti nzira yapfuura yakareruka nekuda kwezvikonzero zvinotevera.

Kutanga, inotora kuti yega yega calorie inodyiwa imwe calorie inopedzwa kuburikidza nekudya.Asi maererano nechinyorwa chekuongorora ichi chine musoro unoti "Migumisiro Yekurovedza muviri paKudya Kwekudya uye Kufutisa Kwemuviri: Pfupiso Yekutsvagisa Kwakadhindwa", kana vanhu vachipisa macalorie akawanda kuburikidza nekurovedza muviri, kazhinji havadyi macalorie akawanda mukudya kwavo ...

Mune mamwe mazwi, ivo vanorasikirwa uremu nekushaiwa macalorie.Naizvozvo, ongororo iyi inogona kuwedzeredza kuburitswa kwechikafu kwemabhasikoro.

Chechipiri, inofunga kuti vanhu havashanduki rudzi rwezvokudya panguva yekurovedza muviri, chete huwandu.Zvokudya zvakasiyana zvine maitiro akasiyana zvakanyanya pane zvakatipoteredza.

Panguva imwe cheteyo, hazvirangariri kuti kana vanhu vakachovha mabhasikoro kakawanda, vanogona kugeza kakawanda, kuwacha hembe dzakawanda, kana kushandisa mari yakawanda pane mamwe mabasa anosvibisa (izvo vezvemhoteredzo vanodana kuti Rebound effect).

Ndeipi mutengo wezvakatipoteredza kugadzira bhasikoro?

Kugadzira mabhasikoro kunoda huwandu hwesimba, uye kusvibiswa kuchaitika nenzira isingadzivisiki.

Sezvineiwo, basa rakawanda rakaitwa muchidzidzo ichi chine musoro unoti "Quantifying Bicycle CO2 Emissions" yakaitwa neEuropean Bicycle Federation (ECF).

Munyori anoshandisa dhata kubva kune yakajairwa dhatabhesi inonzi ecoinvent, iyo inotsanangura iyo yekugovera cheni nharaunda kukanganisa kwezvinhu zvakasiyana uye zvigadzirwa.

Kubva pane izvi, vakaverenga kuti kugadzira bhasikoro reDutch rine huremu huremu hwe19.9 kg uye kunyanya yakagadzirwa nesimbi yaizoguma ne96 kg yecarbon dioxide emissions.

Ichi chiverengero chinosanganisira kugadzira masipari anodiwa muhupenyu hwayo hwose.Vanotenda kuti zvinobuda mukurasa kana kudzokororwazve kwemabhasikoro hazvina basa.

CO2e (CO2 yakaenzana) inoreva huwandu hwekudziya kwepasi rose kwemagasi egreenhouse (kusanganisira CO2, methane, N2O, zvichingodaro) anoburitswa, anoratidzwa seyakachena CO2 mass inodiwa kukonzera huwandu hwakafanana hwekudziya mukati memakore zana.

Maererano nedata kubva kuWorld Steel Association, pakirogiramu yega yega yesimbi inogadzirwa, avhareji ye1.9 kilogiramu yecarbon dioxide inoburitswa.

Maererano neshumo "Environmental Overview yeAluminium muEurope", pakirogiramu yega yega yealuminium inogadzirwa, avhareji ye18 kilograms ye carbon dioxide inosunungurwa, asi iyo carbon cost yekudzokororazve aluminium inongova 5% yezvakagadzirwa.

Zviripachena, kuburitsa kubva kuindasitiri yekugadzira kunosiyana kubva kune chinhu kuenda kune chinhu, saka zvinoburitswa kubva muindasitiri yekugadzira zvinosiyanawo kubva pabhasikoro kuenda kune bhasikoro.

Chirevo cheDuke University chinofungidzira kuti kugadzirwa kwealuminium alloy-specific Allez road frames chete kunoburitsa 250 kg yecarbon dioxide emissions, ukuwo kabhoni fiber-chaiyo Rubaix furemu inogadzira 67 kg yecarbon dioxide emissions.

Munyori anotenda kuti kupisa kwekupisa kwepamusoro-yekupedzisira aluminium mafuremu kunowedzera zvakanyanya kudiwa kwesimba uye kabhoni tsoka yeindasitiri yekugadzira.Zvisinei, munyori anoratidza kuti chidzidzo ichi chinogona kunge chine zvikanganiso zvakawanda.Takakumbira vanyori nevamiriri venyanzvi dzechidzidzo chino kuti vatsanangure pamusoro peizvi, asi hatisati tawana mhinduro.

Nekuda kwekuti nhamba idzi dzinogona kunge dzisiri dzechokwadi uye dzisingamiriri indasitiri yese yemabhasikoro, tichashandisa European Economic Cooperation Organisation (ECF) inofungidzirwa kuti carbon dioxide emission pabhasikoro inosvika 96 kg, asi ziva kuti kabhoni yebhasikoro rega rega inogona kunge iri musiyano mukuru kwazvo.

Chokwadika, magasi egreenhouse handiro bedzi chinetso mukugadzira mabhasikoro.Kune zvakare kusvibiswa kwemvura, kusvibiswa kwemhepo, marashi, nezvimwewo, izvo zvinozokonzera mamwe matambudziko kunze kwekushanduka kwemamiriro ekunze.Chinyorwa ichi chinongotarisa nezve kukanganisa kwebhasikoro pakudziya kwepasi.

Kugadzira emissions pakiromita

ECF inofungidzira zvakare kuti avhareji yehupenyu hwebhasikoro i19,200 makiromita.

Naizvozvo, kana makirogiramu makumi mapfumbamwe nematanhatu ecarbon dioxide emissions anodiwa kugadzira bhasikoro akagovaniswa mukati mechikamu chemakiromita gumi nepfumbamwe nemazana maviri, ipapo indasitiri yekugadzira inoburitsa magiramu mashanu ecarbon dioxide pakiromita.

Ndeipi mutengo wecarbon pachikafu chinodiwa kugadzira kiromita imwe chete?

ECF yakaverenga kuti mutyairi webhasikoro avhareji yemakiromita gumi nematanhatu paawa, anorema makirogiramu makumi manomwe, uye anodya macalorie 280 paawa, nepo kana akasachovha bhasikoro, anopisa 105 macalorie paawa.Naizvozvo, mutasvi webhasikoro anodya avhareji ye175 macalorie pamakiromita gumi nematanhatu;izvi zvakaenzana nemacalorie gumi nerimwe pakiromita.

Macalorie mangani anopisa bhasikoro?

Kushandura izvi kuita zvinobuda pakiromita, tinodawo kuziva avhareji yekubuda kwegasi regreenhouse pacalorie yechikafu chinogadzirwa.Hutsi hunobva mukugadzirwa kwechikafu hunotora nzira dzakawanda, kusanganisira kuchinja kwekushandiswa kwevhu (zvakadai semafashamo uye kutemwa kwemasango), kugadzirwa kwefetereza, kubuda kwezvipfuyo, kufambisa, uye kuchengetwa kwechando.Zvakakodzera kutaura kuti chekufambisa (mamaira echikafu) chinongoverengera chikamu chidiki chehuwandu hwekubuda kubva muhurongwa hwekudya.

Kazhinji, zvinoshuviwa zvikuru kuderedza kubudiswa kwekabhoni nekuchovha bhasikoro.
