Qhov no yog ib…”ntau heev nyob rau hauv-tob”… tsheb kauj vab tsab xov xwm |EWIG

Txhua zaus koj ntsib teeb meem tsheb khiav thaum sawv ntxov thiab yav tsaus ntuj, koj puas xav tias nws yuav zoo dua yog tias muaj coob tus neeg caij tsheb kauj vab mus ua haujlwm?"Okay, ntau npaum li cas zoo dua?"Ntau thiab ntau lub teb chaws tau cog lus raws cai kom ua tiav xoom net carbon emissions los ntawm 2050, thiab UK yog ib qho ntawm lawv.

Txawm hais tias peb tau ua tiav hauv qee qhov chaw, emissions los ntawm kev thauj mus los tseem nce ntxiv.Yog tias peb tsis hloov txoj hauv kev hauv peb lub neej, peb tsis tuaj yeem ncav cuag xoom.Yog li, cycling yog ib feem ntawm kev daws teeb meem?

Txhawm rau nkag siab txog qhov muaj feem cuam tshuam ntawm kev caij tsheb kauj vab rau yav tom ntej, peb yuav tsum teb ob lo lus nug tseem ceeb:

1. Tus nqi carbon ntawm kev caij tsheb kauj vab yog dab tsi?Nws piv rau lwm txoj kev thauj mus los li cas?

2. Kev caij tsheb kauj vab loj puas yuav cuam tshuam rau peb cov pa roj carbon monoxide?

Txoj kev tshawb nrhiav pom tias cov pa roj carbon hneev taw ntawm kev caij tsheb kauj vab yog li 21 grams carbon dioxide ib mais.Qhov no tsawg dua li taug kev lossis caij tsheb npav, thiab cov pa tawm tsawg dua li ib feem kaum ntawm kev tsav tsheb.

Kwv yees li peb feem peb ntawm cov tsheb kauj vab tsev cog khoom roj emissions tshwm sim thaum cov khoom noj ntxiv uas xav tau los tsim "roj" tsheb kauj vab, tus so yog los ntawm kev ua tsheb kauj vab.

Cov pa roj carbon footprint ntawmhluav taws xob tsheb kauj vabtxawm tias qis dua cov tsheb kauj vab ib txwm muaj vim tias txawm hais tias siv roj teeb thiab hluav taws xob siv hluav taws xob tsim tawm, lawv hlawv calories tsawg dua ib mais.

Carbon fiber roob tsheb tuam

Yuav ua li cas ib puag ncig tus phooj ywg yog lub tsheb kauj vab raws li hom kev thauj mus los?

Yuav kom sib piv cov emissions ntawmcarbon fiber tsheb kauj vabthiab lwm lub tsheb, peb yuav tsum xam tag nrho cov pa hluav taws xob hauv tsev cog khoom ib mais.

Qhov no yuav tsum tau tshawb xyuas lub neej voj voog.Kev ntsuas lub neej yog siv los sib piv cov emissions ntawm ntau yam khoom, los ntawm cov fais fab nroj tsuag mus rau gaming consoles.

Lawv lub hauv paus ntsiab lus ua haujlwm yog ntxiv tag nrho cov emissions thaum lub sij hawm cov khoom lag luam tag nrho lub neej (tsim, kev ua haujlwm, kev saib xyuas, thiab pov tseg) thiab faib los ntawm cov txiaj ntsig zoo uas cov khoom tuaj yeem muab tau thaum lub sijhawm nws lub neej.

Rau qhov chaw nres tsheb fais fab, qhov tso zis no yuav yog tag nrho cov hluav taws xob hluav taws xob uas nws tsim thaum lub neej;rau lub tsheb lossis lub tsheb kauj vab, nws yog tus lej ntawm kev mus ncig.Txhawm rau xam cov emissions ib kilometer ntawm lub tsheb kauj vab rau kev sib piv nrog rau lwm hom kev thauj mus los, peb yuav tsum paub:

Greenhouse gas emissions ntsig txogkev tsim tsheb kauj vabthiab ua.Tom qab ntawd faib los ntawm qhov nruab nrab tus lej ntawm mais ntawm kev tsim khoom thiab kev ua haujlwm.

Cov emissions tsim los ntawm cov khoom noj ntxiv uas tsim tawm ib mais muab roj rau cov neeg caij tsheb kauj vab.Qhov no yog ua tiav los ntawm kev suav cov calories ntxiv uas yuav tsum tau ua hauv ib mais kev voj voog thiab muab faib los ntawm qhov nruab nrab cov zaub mov tsim tawm emissions ib calorie ntau ntau.

Nws tsim nyog lees paub tias txoj kev dhau los no yooj yim dhau vim yog cov laj thawj hauv qab no.

Ua ntej, nws xav tias txhua calorie ntau ntxiv yog lwm calorie noj los ntawm kev noj zaub mov.Tab sis raws li tsab xov xwm tshuaj xyuas no hu ua "Qhov cuam tshuam ntawm kev tawm dag zog ntawm kev noj zaub mov thiab lub cev rog: Cov ntsiab lus ntawm Kev Tshawb Fawb Tshaj Tawm", thaum tib neeg hlawv calorie ntau ntau los ntawm kev tawm dag zog, lawv feem ntau tsis haus ntau calories hauv lawv cov zaub mov ...

Hauv lwm lo lus, lawv poob phaus los ntawm tsis muaj calories.Yog li ntawd, qhov kev tshuaj ntsuam no yuav overestimate cov zaub mov emissions ntawm lub tsheb kauj vab.

Qhov thib ob, nws xav tias tib neeg tsis hloov cov khoom noj thaum lub sijhawm ua haujlwm, tsuas yog qhov ntau.Cov khoom noj sib txawv muaj qhov sib txawv heev rau ib puag ncig.

Nyob rau tib lub sijhawm, nws tsis suav tias yog tias tib neeg caij tsheb kauj vab ntau zaus, lawv yuav tau da dej ntau dua, ntxhua khaub ncaws ntau dua, lossis siv nyiaj ntau dua rau lwm yam kev ua qias tuaj (dab tsi uas cov neeg nyob ib puag ncig hu ua Rebound effect).

Suav carbon roob tsheb tuam

Tus nqi ib puag ncig ntawm kev ua tsheb kauj vab yog dab tsi?

Ua tsheb kauj vab yuav tsum muaj qee lub zog, thiab kev ua qias tuaj yuav tshwm sim.

Hmoov zoo, ntau txoj haujlwm tau ua tiav hauv txoj kev tshawb fawb no hu ua "Quantifying Bicycle CO2 Emissions" ua los ntawm European Bicycle Federation (ECF).

Tus kws sau ntawv siv cov ntaub ntawv los ntawm tus txheej txheem database hu ua ecoinvent, uas faib cov saw hlau ib puag ncig cuam tshuam ntawm ntau yam khoom thiab cov khoom.

Los ntawm qhov no, lawv suav tias kev tsim lub tsheb kauj vab Dutch nrog qhov hnyav nruab nrab ntawm 19.9 kg thiab feem ntau ua los ntawm cov hlau yuav ua rau 96 kg ntawm carbon dioxide emissions.

Daim duab no suav nrog kev tsim khoom seem uas xav tau thoob plaws hauv nws lub neej.Lawv ntseeg tias cov emissions los ntawm kev pov tseg lossis rov ua dua tshiab ntawm cov tsheb kauj vab yog qhov tsis tsim nyog.

CO2e (CO2 sib npaug) yog hais txog tag nrho lub ntiaj teb ua kom sov lub peev xwm ntawm tag nrho cov tsev cog khoom gases (xws li CO2, methane, N2O, thiab lwm yam) emitted, qhia raws li cov ntshiab CO2 huab hwm coj yuav tsum tau ua kom sov li qub nyob rau hauv 100-xyoo lub sij hawm.

Cov teeb meem khoom siv

Raws li cov ntaub ntawv los ntawm World Steel Association, rau txhua kilogram ntawm cov hlau tsim, qhov nruab nrab ntawm 1.9 kilograms ntawm carbon dioxide tawm.

Raws li tsab ntawv ceeb toom "Environmental Overview of Aluminium nyob teb chaws Europe", rau txhua kilogram ntawm txhuas tsim, qhov nruab nrab ntawm 18 kilograms ntawm carbon dioxide raug tso tawm, tab sis cov pa roj carbon nqi ntawm recycling txhuas tsuas yog 5% ntawm raw khoom.

Obviously, cov emissions los ntawm kev tsim kev lag luam sib txawv ntawm cov khoom mus rau cov khoom, yog li cov emissions los ntawm kev tsim kev lag luam kuj txawv ntawm lub tsheb kauj vab mus rau lub tsheb kauj vab.

Lub Duke University tsab ntawv ceeb toom kwv yees tias kev tsim cov txhuas alloy-tshwj xeeb Allez txoj kev thav ntawv ib leeg ua rau 250 kg ntawm carbon dioxide emissions, thaum cov roj carbon fiber tshwj xeeb Rubaix ncej tsim 67 kg ntawm carbon dioxide emissions.

Tus kws sau ntawv ntseeg tias kev kho cua sov ntawm high-end aluminium thav duab ua rau kom lub zog xav tau thiab cov pa roj carbon hneev taw ntawm kev tsim khoom lag luam.Txawm li cas los xij, tus kws sau ntawv taw qhia tias qhov kev tshawb fawb no yuav muaj qhov tsis raug ntau.Peb tau hais kom cov kws sau ntawv thiab cov kws tshaj lij cov neeg sawv cev ntawm txoj kev tshawb fawb no piav qhia txog qhov no, tab sis tseem tsis tau txais lus teb.

Vim tias cov lej no yuav tsis raug thiab tsis sawv cev rau tag nrho kev lag luam tsheb kauj vab, peb yuav siv European Economic Kev Koom Tes Koom Tes (ECF) kwv yees cov pa roj carbon dioxide emissions rau ib lub tsheb kauj vab yog 96 kg, tab sis nco ntsoov tias cov pa roj carbon hneev taw ntawm txhua lub tsheb kauj vab tuaj yeem yog sib txawv loj heev.

Yog lawm, tsev cog khoom gases tsis yog ib qho teeb meem ntawm kev ua tsheb kauj vab.Kuj tseem muaj dej paug, huab cua muaj kuab paug, pov tseg, thiab lwm yam, uas yuav ua rau muaj teeb meem ntxiv rau kev hloov pauv huab cua.Kab lus no tsuas yog tsom mus rau qhov cuam tshuam ntawm kev caij tsheb kauj vab ntawm lub ntiaj teb ua kom sov.

Kev tsim tawm emissions ib kilometer

ECF kwv yees ntxiv tias qhov nruab nrab lub neej ntawm lub tsheb kauj vab yog 19,200 mais.

Yog li ntawd, yog hais tias lub 96 kilograms ntawm carbon dioxide emissions yuav tsum tau los tsim ib lub tsheb kauj vab yog faib nyob rau hauv ib tug deb ntawm 19,200 kilometers, ces kev lag luam tsim yuav emission 5 grams ntawm carbon dioxide ib kilometer.

Cov pa roj carbon nqi ntawm cov zaub mov yog dab tsi los tsim ib mais?

ECF suav hais tias tus neeg caij tsheb kauj vab nruab nrab yog 16 mais ib teev, hnyav 70 kilograms, thiab noj 280 calories ib teev, thaum lawv tsis caij tsheb kauj vab, lawv hlawv 105 calories ib teev.Yog li ntawd, tus neeg caij tsheb kauj vab siv qhov nruab nrab ntawm 175 calories ib 16 km;qhov no yog sib npaug rau 11 calories ib kilometer.

Muaj pes tsawg calories uas cycling hlawv?

Txhawm rau hloov qhov no mus rau hauv emissions ib kilometer, peb kuj yuav tsum paub qhov nruab nrab lub tsev cog khoom roj emissions ib calorie ntawm cov zaub mov tsim.Kev xa tawm los ntawm kev tsim khoom noj muaj ntau yam, suav nrog kev hloov pauv hauv av (xws li dej nyab thiab deforestation), kev tsim cov chiv, tsiaj txhu emissions, tsheb thauj mus los, thiab kev cia txias.Nws tsim nyog taw qhia tias kev thauj mus los (cov khoom noj mais) tsuas yog suav rau ib feem me me ntawm tag nrho cov emissions los ntawm cov zaub mov.

Feem ntau, nws yog qhov tsim nyog los txo cov pa roj carbon monoxide los ntawm kev caij tsheb kauj vab.
