Nthawi zonse mukakumana ndi vuto la magalimoto m'mamawa ndi madzulo, kodi mukuganiza kuti zingakhale bwino ngati anthu ambiri akukwera njinga kupita kuntchito?"Chabwino, kuli bwino bwanji?"Mayiko ochulukirachulukira adalonjeza mwalamulo kuti apeza ziro zotulutsa mpweya wa kaboni pofika 2050, ndipo UK ndi amodzi mwa iwo.
Ngakhale kuti tapita patsogolo m’madera ena, mpweya wotuluka m’zamsewu ukupitiriza kukwera.Ngati sitisintha njira m'moyo wathu, sitingathe kufikira ziro.Ndiye, kodi kukwera njinga ndi gawo lothandizira?
Kuti timvetsetse momwe kukwera njinga kungakhudzire tsogolo lokhazikika, tiyenera kuyankha mafunso awiri ofunika:
1. Kodi mtengo wa kaboni pakupalasa njinga ndi wotani?Kodi zimasiyana bwanji ndi mayendedwe ena?
2. Kodi kuwonjezeka kochititsa chidwi kwa kupalasa njinga kudzakhala ndi chiyambukiro cha mpweya wathu?
Kafukufukuyu adapeza kuti kaboni wapanjinga panjinga ndi pafupifupi magalamu 21 a carbon dioxide pa kilomita imodzi.Izi ndizocheperapo kuyenda kapena kukwera basi, ndipo mpweya wake umakhala wochepera pa gawo limodzi mwa magawo khumi la kuyendetsa.
Pafupifupi magawo atatu mwa magawo atatu a mpweya wowonjezera kutentha kwa njinga kumachitika pamene chakudya chowonjezera chimafunika kupanga njinga za "mafuta", zina zonse zimachokera kupanga njinga.
Chizindikiro cha carbonnjinga zamagetsindizotsika kwambiri kuposa zanjinga zachikhalidwe chifukwa ngakhale kupanga mabatire ndi kugwiritsa ntchito magetsi kumatulutsa mpweya, zimawotcha zopatsa mphamvu zochepa pa kilomita imodzi.
Kodi njinga imateteza bwanji chilengedwe ngati njira yoyendera?
Pofuna kufananiza mpweya wanjinga za carbon fiberndi magalimoto ena, tiyenera kuwerengera kuchuluka kwa mpweya wowonjezera kutentha pa kilomita imodzi.
Izi zimafuna kusanthula moyo wanu.Kuwunika kozungulira kwa moyo kumagwiritsidwa ntchito kufananiza mpweya wazinthu zosiyanasiyana, kuchokera kumagetsi kupita kuzinthu zamasewera.
Mfundo yawo yogwirira ntchito ndikuphatikiza magwero onse otulutsa mpweya pa moyo wa chinthucho (kupanga, kugwira ntchito, kukonza, ndi kutaya) ndikugawa ndi zofunikira zomwe chinthucho chingapereke pamoyo wake.
Kwa malo opangira magetsi, kutulutsa uku kungakhale kuchuluka kwa mphamvu yamagetsi yomwe imapanga m'moyo wake;kwa galimoto kapena njinga, ndi chiwerengero cha makilomita oyenda.Kuti tiwerengere mpweya wotuluka pa kilomita imodzi ya njinga kuyerekeza ndi mayendedwe ena, tiyenera kudziwa:
Kutulutsa mpweya wowonjezera kutentha kumakhudzana ndikupanga njingandi processing.Kenaka gawani ndi chiwerengero cha makilomita pakati pa kupanga ndi kukonza.
Utsi wopangidwa ndi chakudya chowonjezera chomwe chimapangidwa pa kilomita imodzi umapereka mafuta kwa okwera njinga.Izi zimachitika powerengera ma calories owonjezera omwe amafunikira pa kilometre imodzi ndikuchulukitsa ndi kuchuluka kwa mpweya womwe umatulutsa pa calorie yopangidwa.
Ndikoyenera kuvomereza kuti njira yapitayi ndi yosavuta chifukwa cha zifukwa zotsatirazi.
Choyamba, zimaganiza kuti calorie yowonjezera iliyonse yomwe imadyedwa ndi calorie ina yomwe imadyedwa kudzera muzakudya.Koma molingana ndi nkhani yowunikirayi yomwe ili ndi mutu wakuti "Zotsatira za Kuchita Zolimbitsa Thupi pa Kudya Zakudya ndi Kunenepa Kwambiri M'thupi: Chidule Cha Kafukufuku Wofalitsidwa", pamene anthu amawotcha ma calories ochulukirapo pogwiritsa ntchito masewera olimbitsa thupi, nthawi zambiri sadya ma calories ambiri muzakudya zawo ...
Mwa kuyankhula kwina, amawonda chifukwa chosowa zopatsa mphamvu.Chifukwa chake, kusanthula uku kungathe kupitilira kutulutsa kwachakudya kwanjinga.
Chachiwiri, akuganiza kuti anthu sasintha mtundu wa chakudya panthawi yolimbitsa thupi, koma kuchuluka kwake.Zakudya zosiyanasiyana zimakhala ndi zotsatira zosiyana kwambiri pa chilengedwe.
Panthawi imodzimodziyo, sizimaganizira kuti ngati anthu amakwera njinga nthawi zambiri, amatha kusamba kwambiri, kuchapa zovala zambiri, kapena kuwononga ndalama zambiri pazinthu zina zoipitsa (zomwe akatswiri a zachilengedwe amatcha Rebound effect).
Kodi chilengedwe chimawononga ndalama zingati popanga njinga?
Kupanga njinga kumafuna mphamvu inayake, ndipo kuipitsa kudzachitika mosapeŵeka.
Mwamwayi, ntchito zambiri zachitika mu kafukufukuyu wakuti "Quantifying Bicycle CO2 Emissions" yochitidwa ndi European Bicycle Federation (ECF).
Wolemba amagwiritsa ntchito deta yochokera ku database yodziwika bwino yotchedwa ecoinvent, yomwe imayika m'magulu azinthu zachilengedwe zomwe zimakhudzidwa ndi zinthu zosiyanasiyana.
Kuchokera pa izi, adawerengera kuti kupanga njinga yamtundu wa Dutch yokhala ndi kulemera kwapakati pa 19.9 kg ndipo makamaka yopangidwa ndi chitsulo kungapangitse 96 kg ya carbon dioxide.
Chiwerengerochi chikuphatikiza kupanga zida zosinthira zomwe zimafunikira moyo wake wonse.Amakhulupirira kuti mpweya wochokera kutayidwa kapena kubwezeredwanso kwa njinga ndi wosafunika.
CO2e (CO2 yofanana) imatanthawuza kuchuluka kwa kutentha kwa dziko lonse kwa mpweya wowonjezera kutentha (kuphatikizapo CO2, methane, N2O, ndi zina zotero) zomwe zimatulutsidwa, zomwe zimafotokozedwa ngati CO2 yoyera yofunikira kuti ipangitse kutentha komweko muzaka 100.
Nkhani zakuthupi
Malinga ndi kafukufuku wa World Steel Association, pa kilogalamu iliyonse yazitsulo zopangidwa, pafupifupi 1.9 kilogalamu ya carbon dioxide imatulutsidwa.
Malinga ndi lipoti la "Environmental Overview of Aluminium in Europe", pa kilogalamu iliyonse ya aluminiyamu yopangidwa, pafupifupi makilogalamu 18 a carbon dioxide amatulutsidwa, koma mtengo wa carbon wobwezeretsanso aluminiyumu ndi 5% yokha ya zopangira.
Mwachiwonekere, mpweya wochokera kumakampani opanga zinthu umasiyana kuchokera kuzinthu zina, kotero kuti mpweya wochokera kumakampani opanga zinthu umasiyananso kuchokera panjinga kupita panjinga.
Lipoti la Duke University likuyerekeza kuti kupanga mafelemu a aluminium alloy-enieni a Allez mumsewu yekha kumapanga 250 kg ya mpweya woipa wa carbon dioxide, pamene mpweya wa carbon fiber-enieni wa Rubaix umapanga 67 kg ya carbon dioxide.
Wolembayo amakhulupirira kuti kutentha kwa mafelemu apamwamba a aluminiyamu kumawonjezera kwambiri kufunikira kwa mphamvu ndi carbon footprint ya mafakitale opanga.Komabe, wolembayo akunena kuti phunziroli likhoza kukhala ndi zolakwika zambiri.Tapempha olemba komanso oimira akatswiri a kafukufukuyu kuti afotokoze zambiri za izi, koma sitinayankhebe.
Chifukwa ziwerengerozi zitha kukhala zolakwika ndipo sizikuyimira makampani onse anjinga, tidzagwiritsa ntchito bungwe la European Economic Cooperation Organisation (ECF) lomwe likuyerekeza kuti mpweya woipa wa carbon dioxide pa njinga umakhala wokwana 96 kg, koma dziwani kuti mpweya wa njinga iliyonse ukhoza kukhala kusiyana kwakukulu.
N’zoona kuti si mipweya yotenthetsa dziko yokha imene imavuta kupanga njinga.Palinso kuipitsa madzi, kuwonongeka kwa tinthu ta mpweya, zotayiramo, ndi zina zotero, zomwe zingayambitse mavuto ena kupatula kusintha kwa nyengo.Nkhaniyi imangoyang'ana kwambiri zomwe zimachitika panjinga pakusintha kwanyengo.
Kutulutsa mpweya pa kilomita
ECF ikuyerekezanso kuti moyo wanjinga ndi makilomita 19,200.
Chifukwa chake, ngati ma kilogalamu 96 a mpweya woipa wofunikira kuti apange njinga agawidwe mkati mwa makilomita 19,200, ndiye kuti makampani opanga adzatulutsa magalamu a 5 a carbon dioxide pa kilomita imodzi.
Kodi mpweya wa carbon umakhala wotani pa chakudya chofunika kupanga kilomita imodzi?
ECF inawerengera kuti woyendetsa njinga amafika pafupifupi makilomita 16 pa ola, amalemera makilogalamu 70, ndipo amadya ma calories 280 pa ola, pamene ngati sakukwera njinga, amawotcha ma calories 105 pa ola limodzi.Choncho, woyendetsa njinga amadya pafupifupi ma calories 175 pa kilomita 16;Izi ndizofanana ndi ma calories 11 pa kilomita imodzi.
Kodi kupalasa njinga kumawotcha zopatsa mphamvu zingati?
Kuti tisinthe izi kukhala mpweya wotuluka pa kilomita imodzi, tiyeneranso kudziwa kuchuluka kwa mpweya wowonjezera kutentha pa calorie ya chakudya chopangidwa.Mpweya wotuluka m’zakudya umachitika m’njira zosiyanasiyana, kuphatikizapo kusintha kwa kagwiritsidwe ntchito ka nthaka (monga kusefukira kwa madzi ndi kudula mitengo mwachisawawa), kupanga feteleza, kutulutsa mpweya wa ziweto, mayendedwe, ndi kusungirako chisanu.Ndikoyenera kunena kuti zoyendera (zakudya za mailosi) zimangotengera gawo laling'ono la mpweya wokwanira kuchokera ku chakudya.
Nthawi zambiri, ndikofunikira kwambiri kuchepetsa mpweya wa kaboni pokwera njinga.
