Nako le nako ha u tobane le tšubuhlellano ea sephethephethe hoseng le mantsiboea lihora tsa leqhubu, na u nahana hore ho ka ba molemo ha batho ba bangata ba palama libaesekele ho ea mosebetsing?"Ho lokile, ho betere hakae?"Linaha tse ntseng li eketseha li itlamme ka molao hore li tla fumana khabone ea zero net ka 2050, 'me UK ke e' ngoe ea tsona.

Le hoja re tsoetse pele libakeng tse ling, khase ea lipalangoang e ntse e eketseha.Haeba re sa fetole tsela ea bophelo ba rona, re ke ke ra fihlela net zero.Joale, na ho palama baesekele ke karolo ea tharollo?

Ho utloisisa phello e ka bang teng ea ho palama libaesekele bokamosong bo tsitsitseng, re tlameha ho araba lipotso tse peli tsa bohlokoa:

1. Chelete ea khabone ea ho palama baesekele ke bokae?E bapisoa joang le lipalangoang tse ling?

2. Na keketseho e makatsang ea libaesekele e tla ba le tšusumetso molemong oa rona oa khabone?

Phuputso e fumane hore sebaka sa carbon footprint ea baesekele ke hoo e ka bang ligrama tse 21 tsa carbon dioxide k'hilomithara.Sena se ka tlase ho ho tsamaea kapa ho palama bese, 'me likhase li tlase ho karolo ea leshome ea ho khanna.

Hoo e ka bang likarolo tse tharo ho tse tharo tsa likhase tse futhumatsang lefatše li etsahala ha lijo tse eketsehileng tse hlokahalang ho hlahisa libaesekele tsa "fuel", tse ling li tsoa ho etsa libaesekele.

The carbon footprint ealibaesekele tsa motlakasee bile e tlase ho feta ea libaesekele tsa setso hobane leha tlhahiso ea betri le ts'ebeliso ea motlakase li hlahisa mesi, li chesa likhalori tse fokolang ka kilometara.

Baesekele ea thaba ea carbon fiber

Baesekele e na le botsoalle bo bokae e le mokhoa oa ho tsamaea?

E le ho bapisa mesi ealibaesekele tsa carbon fiberle likoloi tse ling, re hloka ho bala palo eohle ea likhase tse futhumatsang lefatše ka kilometara.

Sena se hloka tlhahlobo ea potoloho ea bophelo.Tekolo ea potoloho ea bophelo e sebelisoa ho bapisa mesi ea lihlahisoa tse fapaneng, ho tloha ho litsi tsa motlakase ho ea ho li-consoles tsa lipapali.

Molao-motheo oa bona oa ts'ebetso ke ho kopanya mehloli eohle ea tlhahiso nakong ea bophelo bohle ba sehlahisoa (tlhahiso, ts'ebetso, tlhokomelo le ho lahla) le ho arola ka lihlahisoa tse molemo tseo sehlahisoa se ka fanang ka sona bophelong ba sona.

Bakeng sa seteishene sa motlakase, tlhahiso ena e ka 'na ea e-ba kakaretso ea matla a motlakase ao e a hlahisang nakong ea bophelo ba eona;bakeng sa koloi kapa baesekele, ke palo ea lik'hilomithara tse tsamaileng.Bakeng sa ho bala likhase tsa libaesekele ka k'hilomithara ho li bapisa le mekhoa e meng ea lipalangoang, re hloka ho tseba:

Khase e futhumatsang lefatše e amanang letlhahiso ea libaesekelele ho sebetsa.Ebe u arola ka karolelano ea palo ea lik'hilomithara pakeng tsa tlhahiso le ts'ebetso.

Mesi e hlahisoang ke lijo tse eketsehileng tse hlahisoang ka k'hilomithara li fana ka mafura ho bapalami ba libaesekele.Sena se etsoa ka ho bala lik'hilojule tse eketsehileng tse hlokahalang bakeng sa potoloho ea k'hilomithara le ho li atisa ka karolelano ea tlhahiso ea lijo ka khalori e hlahisoang.

Ke habohlokoa ho hlokomela hore mokhoa o fetileng o bonolo haholo ka lebaka la mabaka a latelang.

Ntlha ea pele, e nka hore khalori e 'ngoe le e' ngoe e eketsehileng e jeoang ke khalori e 'ngoe e jeoang ke lijo.Empa ho ea ka sehlooho sena sa tlhahlobo se nang le sehlooho se reng "Liphello tsa Boikoetliso ba Lijo le Botenya ba 'Mele: Kakaretso ea Lipatlisiso Tse Phatlalalitsoeng", ha batho ba chesa lik'hilojule tse ngata ka ho ikoetlisa, hangata ha ba je lik'hilojule tse ngata lijong tsa bona ...

Ka mantsoe a mang, ba theola boima ba 'mele ka ho hloka lik'hilojule.Ka hona, tlhahlobo ena e ka 'na ea lekanya ho feta tekano ho tsoa lijong tsa libaesekele.

Ea bobeli, e nka hore batho ha ba fetole mofuta oa lijo nakong ea boikoetliso, ke bongata feela.Lijo tse fapaneng li na le litlamorao tse fapaneng haholo tikolohong.

Ka nako e tšoanang, ha e nahane hore haeba batho ba palama libaesekele khafetsa, ba ka ’na ba hlapa haholoanyane, ba hlatsoa liaparo tse ngata, kapa ba sebelisa chelete e ngata mesebetsing e meng e silafatsang (seo litsebi tsa tikoloho li se bitsang Rebound effect).

baesekele ea thaba ea chaena ea carbon

Chelete ea tikoloho ea ho etsa baesekele ke bokae?

Ho etsa libaesekele ho hloka tekanyo e itseng ea matla, 'me ntle ho pelaelo tšilafalo e tla etsahala.

Ka lehlohonolo, ho entsoe mosebetsi o mongata thutong ena e nang le sehlooho se reng "Quantifying Bicycle CO2 Emissions" e entsoeng ke European Bicycle Federation (ECF).

Sengoli se sebelisa data ho tsoa ho database e tloaelehileng e bitsoang ecoinvent, e khethollang phello ea tikoloho ea phepelo ea lisebelisoa le lihlahisoa tse fapaneng.

Ho tsoa ho sena, ba ile ba lekanya hore ho etsa baesekele ea baeti ea Madache e boima ba lik'hilograma tse 19.9 'me haholo-holo e entsoe ka tšepe e tla fella ka lik'hilograma tse 96 tsa carbon dioxide.

Palo ena e kenyelletsa ho etsa likarolo tse ling tse hlokahalang bophelong bohle ba eona.Ba lumela hore mesi e tsoang ho lahloa kapa ho e sebelisa hape ea libaesekele ha e na thuso.

CO2e (e lekanang le CO2) e bolela bokhoni ba ho futhumala ha lefatše kaofela ha likhase tsohle tse futhumatsang lefatše (ho kenyeletsoa CO2, methane, N2O, joalo-joalo) tse hlahisitsoeng, tse hlahisoang e le boima bo hloekileng ba CO2 bo hlokahalang ho baka palo e lekanang ea mocheso nakong ea lilemo tse 100.

Litaba tse bonahalang

Ho ea ka boitsebiso bo tsoang ho World Steel Association, bakeng sa kilogram e 'ngoe le e' ngoe ea tšepe e hlahisoang, karolelano ea lik'hilograma tse 1,9 tsa carbon dioxide e ntšoa.

Ho ea ka tlaleho ea "Environmental Overview of Aluminium in Europe", bakeng sa kilogram e 'ngoe le e' ngoe ea aluminium e hlahisoang, ka karolelano ho lokolloa lik'hilograma tse 18 tsa carbon dioxide, empa litšenyehelo tsa carbon tsa ho tsosolosa aluminium ke 5% feela ea thepa e tala.

Ho hlakile hore mesi e tsoang indastering ea tlhahiso e fapana ho ea ka thepa, ka hona, mesi e tsoang indastering ea tlhahiso le eona e fapana ho ea ka libaesekele.

Tlaleho ea Univesithi ea Duke e hakanya hore tlhahiso ea liforeimi tse khethehileng tsa aluminium alloy-specific Allez feela e hlahisa 250 kg ea carbon dioxide e hlahisoang, ha foreimi ea carbon fiber-specific Rubaix e hlahisa 67 kg ea carbon dioxide e hlahisoang.

Mongoli o lumela hore phekolo ea mocheso ea liforeimi tse phahameng tsa aluminium e eketsa haholo tlhokahalo ea matla le carbon footprint ea indasteri ea tlhahiso.Leha ho le joalo, mongoli o bontša hore thuto ena e ka ’na ea e-ba le mefokolo e mengata.Re kopile bangoli le baemeli ba litsebi ba phuputso ena ho hlakisa taba ena, empa ha re so fumane karabo.

Hobane lipalo tsena li ka 'na tsa se ke tsa nepahala ebile ha li emele indasteri eohle ea libaesekele, re tla sebelisa European Economic Cooperation Organization (ECF) e hakantsoeng hore carbon dioxide e hlahisoa ka baesekele e le 96 kg, empa hlokomela hore sebaka sa carbon footprint ea baesekele ka 'ngoe e ka ba phapang e kgolo haholo.

Ke ’nete hore likhase tse futhumatsang lefatše hase tsona feela bothata ba ho etsa libaesekele.Hape ho na le tšilafalo ea metsi, tšilafalo ea likaroloana tsa moea, lithōle, joalo-joalo, tse tla baka mathata a mang ntle le phetoho ea boemo ba leholimo.Sengoliloeng sena se shebane feela le phello ea ho palama libaesekele ho futhumala ha lefatše.

Mesi e hlahisoang ka k'hilomithara

ECF e boetse e hakanya hore nako ea bophelo ba baesekele ke lik'hilomithara tse 19,200.

Ka hona, haeba lik'hilograma tse 96 tsa likhase tsa carbon dioxide tse hlokahalang ho etsa baesekele li ka aroloa ka har'a sebaka sa lik'hilomithara tse 19,200, joale indasteri ea tlhahiso e tla ntša ligrama tse 5 tsa carbon dioxide k'hilomithara ka 'ngoe.

Chelete ea khabone ea lijo tse hlokahalang ho hlahisa k'hilomithara e le 'ngoe ke bokae?

ECF e ile ea lekanya hore mopalami oa libaesekele ke karolelano ea lik’hilomithara tse 16 ka hora, boima ba lik’hilograma tse 70, ’me o ja lik’hilojule tse 280 ka hora, athe ha a sa palame baesekele, a chesa lik’hilojule tse 105 ka hora.Ka hona, mopalami oa baesekele o ja karolelano ea lik'hilojule tse 175 k'hilomithara tse 16;sena se lekana le lik'hilojule tse 11 k'hilomithara.

Ho palama libaesekele ho chesa lik'hilojule tse kae?

Ho fetolela sena hore e be mesi ka khilomithara, re boetse re hloka ho tseba karolelano ea likhase tse futhumatsang lefatše ka khalori ea lijo tse hlahisoang.Mesi e hlahisoang ke tlhahiso ea lijo e nka mefuta e mengata, ho kopanyelletsa le liphetoho tsa tšebeliso ea mobu (tse kang likhohola le ho rengoa ha meru), tlhahiso ea manyolo, mesi ea liphoofolo tse ruuoang, lipalangoang le polokelo e batang.Ke habohlokoa ho bontša hore lipalangoang (lik'hilomithara tsa lijo) li ikarabella feela bakeng sa karolo e nyenyane ea mesi eohle e tsoang tsamaisong ea lijo.

Ka kakaretso, ke ntho e lakatsehang haholo ho fokotsa tlhahiso ea khabone ka ho palama baesekele.
