I-carbon footprint yezokuvakasha emhlabeni wonke ikhula ngokushesha

Ucwaningo olusha olwenziwa abacwaningi baseNyuvesi yaseSydney lubonisa ukuthi ezokuvakasha emhlabeni wonke, imboni ebiza amathriliyoni, inegalelo elikhulu ekukhishweni kwesisi esingcolisa umoya futhi i-carbon footprint yayo ikhula ngokushesha.

Ezokuvakasha zasekhaya nezamazwe ngamazwe zenza amaphesenti ayisishiyagalombili engqikithi yokukhishwa kwe-carbon dioxide (CO2) emhlabeni wonke, abacwaningi bathole.

Ucwaningo belusekelwe kudatha evela emazweni ayi-189 emhlabeni jikelele. Kubonise ukuthi imboni ye-carbon footprint yayiqhutshwa ikakhulukazi isidingo sokuhamba ngendiza okudinga amandla.

"Ezokuvakasha kulindeleke ukuthi zikhule ngokushesha kuneminye imikhakha eminingi yezomnotho," njengoba imali engenayo kulindeleke ukuthi ikhule ngamaphesenti amane ngonyaka ngo-2025, kusho umbhali oholayo u-Arunima Malik, umcwaningi esikoleni sebhizinisi saseNyuvesi yaseSydney.

Imboni yezokundiza ithatha amaphesenti amabili azo zonke izikhithi ezikhiqizwe ngabantu ze-C02, futhi ibizokleliswa endaweni ye-12 ukube bekuyizwe. Ngokwe-International Air Transport Association (IATA), isibalo sabagibeli bezindiza kulindeleke ukuthi sicishe siphindeke kabili ngo-2036 siye ku-7.8 billion ngonyaka.

Ingxenye yamaphesenti angu-14 okwanda kwenani lezinto ezikhishwayo ngenxa yezokuvakasha emhlabeni wonke kwenzeka emazweni anemali engenayo ephezulu kusukela ngo-2009 kuya ku-2013, ucwaningo lwathola. Kodwa-ke, amazwe anemali engenayo emaphakathi aqophe izinga lokukhula eliphakeme kakhulu ngamaphesenti ayi-17.4 ngonyaka ngalesi sikhathi.

Njengamashumini eminyaka adlule, i-United States bekuyiyona ehamba phambili yokukhipha isikhutha esihlobene nezokuvakasha. IJalimane, iCanada, neBrithani nazo zaziphakathi kwabayishumi abahamba phambili.

I-China ibisendaweni yesibili kwathi i-India, iMexico, neBrazil isendaweni yesi-4, yesi-5 neyesi-6 ngokulandelana.

"Sibona ukukhula kwesidingo sezokuvakasha esisheshayo esivela eChina naseNdiya eminyakeni embalwa edlule, futhi silindele ukuthi lo mkhuba uzoqhubeka eshumini leminyaka elizayo noma ngaphezulu," u-Ya-Sen Sun, uprofesa e-University of Queensland Business School e-Australia, kanye nombhali ngokubambisana wocwaningo, utshele abe-AFP.

Amazwe aseziqhingini ezincane njengeMaldives, iMauritius, iCyprus, neSeychelles abone phakathi kwamaphesenti angama-30 namaphesenti angama-80 emali ekhishwa ezweni evela kwezokuvakasha zamazwe ngamazwe.

UMalik ukholelwa ukuthi ezokuvakasha zizokhula ngamaphesenti amane ngonyaka, zidlule eminye imikhakha yezomnotho eminingi. Kungakho “kubalulekile” ukulenza lizinze, esho. “Sincoma ukuthi uhambe kancane ngendiza, lapho kungenzeka khona. Zama ukuhlala ugxile eMhlabeni ukuze unciphise ukukhishwa kwegesi.”
