International Methane Emissions Observatory yakavambwa kusimudzira zviito pagasi rine simba rekudziya kwemamiriro ekunze

Kutsigira kumwe kufambira mberi kwekuzadzisa Chibvumirano cheParis, UN Environment Programme (UNEP) nerutsigiro kubva kuEuropean Union yaparura nhasi Observatory nyowani kufambisa chiito chepasi rose mukuderedza kuburitswa kwemethane.

The International Methane Emissions Observatory (IMEO) yakatangwa pa iyo G20 Summit, manheru e Musangano weCOP26 UN nezvemamiriro ekunze muGlasgow. IMEO ichaunza kutaurwa kwepasirese pamusoro pekuburitswa kwemethane kune imwe nhanho yakasiyana, kuve nechokwadi chekubuda pachena kweveruzhinji pane anthropogenic methane emissions. IMEO ichatanga yatarisa kuburitswa kwemethane kubva kufossil fuel sector, yobva yawedzera kune mamwe makuru ekuburitsa sekurima nemarara.  

Methane igasi regreenhouse rine simba rinokonzeresa chikamu chimwe muzvina chekudziya kwepasi. Iyo ichangoburwa UNEP-Climate & Clean Air Coalition (CCAC) Global Methane Assessment inotaura kuti zero kana kuderera kwemutengo-kuderedzwa kunogona kuita nepakati nepakati anthropogenic methane emissions, nepo matanho akapupurirwa anogona kucheka 0.28 madhigirii celsius kubva pakufanotaura kukwira kweavhareji tembiricha yepasi panosvika 2050.

IMEO ichapa nzira dzekuisa pamberi zviito uye kutarisa zvisungo zvakaitwa nevatambi vehurumende mu Global Methane Pledge - kuyedza kutungamirwa neUS neEU nenyika dzinopfuura makumi matatu kuderedza kuburitswa kwemethane ne30% panosvika 2030.

Mutungamiri weEuropean Commission President Ursula von der Leyen vakati: “Methane nderimwe remagasi ane ngozi zvikuru kumamiriro ekunze edu. Tinofanirwa kukurumidza kuderedza kuburitswa kwemethane kuitira kuti tarisiro yedu yemamiriro ekunze isvike. Zvirinani kutarisa setiraiti kwakakosha uye EU inodada kutsigira kusikwa kweInternational Methane Emissions Observatory. "

Methane: pamusoro pe80 nguva yakawanda kupfuura CO₂

Kuti urambe uri munzira yechinangwa cheChibvumirano cheParis chekudzikamisa shanduko yemamiriro ekunze kusvika 1.5 ° C, nyika inoda kupotsa. hafu yekubuda kwegreenhouse gasi panosvika 2030. The Intergovernmental Panel pamusoro peKushanduka Kwemamiriro Okunze (IPCC) inocherekedza kuti kana nyika ichida kuwana tembiricha ye 1.5°C, kudzikisira kuburitswa kwemethane kwakadzika kunofanira kuitwa mumakore gumi ari kutevera.

“Sezvakataurwa neIPCC, kana nyika ichida kunzvenga migumisiro yakaipisisa yokuchinja kwemamiriro okunze, tinofanira kuderedza kubudiswa kwemethane kubva muindasitiri yemafuta ezvicherwa. Asi iyi haisi kadhi remahara rekubuda mujeri: kuderedzwa kwemethane kunofanirwa kufambidzana nezviito zvekubvisa simba remagetsi kudzikamisa kudziya kusvika 1.5 ° C, sekudaidzwa kwakaitwa muchibvumirano cheParis, "akadaro UNEP Executive Director. Inger Andersen.

Methane inoburitswa yakananga mumhepo iri kupfuura 80 nguva ine simba kupfuura CO₂ pamusoro pemakore makumi maviri enguva. Nekudaro, sezvo methane hupenyu hwemuchadenga huri hupfupi - 10 kune makore 12 - zviito zvekucheka kuburitswa kwemethane zvinogona kuburitsa kuderedzwa nekukurumidza kwehuwandu hwekudziya, ukuwo uchiunza mabhenefiti emhando yemhepo.

Komishina wezvemagetsi Kadri Simson akati: “Methane yakatora chikamu chinosvika makumi matatu kubva muzana chekudziya kwepasi kubvira nguva isati yatanga maindasitiri, uye nhasi uno utsi hwayo huri kuwedzera nekukurumidza kupfuura chero imwe nguva kubvira pakatanga kuchengetwa kwema30s. Masisitimu aripo haatibvumidze kuti tinyatsoona kuti kuburitswa uku kunoitika kupi pasi rose uye mumavhoriyamu api. Kana data riri nani ravepo, nyika dzinogona kutora danho rinokurumidza uye rakanangwa zvakanaka. MuEU, isu tichatopa zano rekutanga mutemo wekudzikisa kuburitswa kwemethane gore rino. Izvi zvinosanganisira zvinosungirwa kuona kuvuza uye kugadzirisa uye kudzikisira kubuda uye kupisa. "

Iyo fossil fuel industry ndiyo ine basa chikamu chimwe muzvitatu cheanthropogenic emissions uye ndiro chikamu chine mukana wepamusoro wekuderedza. Iyo methane yakaraswa, chikamu chikuru mugasi rechisikigo, inzvimbo yakakosha yesimba iro rinogona kushandiswa kugadzira magetsi emagetsi kana dzimba.

IMEO: Iyo yakazvimirira uye yakavimbika yepasi rose sangano

Iyo Observatory ichaburitsa yepasirese yeruzhinji dataset ye empirically verified methane emissions - kutanga nefossil fuel sector - pamwero unowedzera we granularity uye kurongeka nekubatanidza data kunyanya kubva kunzizi ina: kushuma kubva ku Oiri neGasi Methane Partnership 2.0 (OGMP 2.0), makambani emafuta uye gasi, data yekuyera yakananga kubva kuzvidzidzo zvesainzi, data inonzwa kure, uye zvinyorwa zvenyika. Izvi zvinobvumira IMEO kuti ibatane nemakambani nehurumende pasi rese kuti vashandise data iri kunanga zviito zvekudzikisira uye kutsigira sarudzo dzesainzi.

Chakakosha pakuedza uku idata rakaunganidzwa kuburikidza neOGMP 2.0 yakatangwa munaNovember 2020 muhurongwa hweCCAC. OGMP 2.0, yakatangwa muna Mbudzi 2020 muhurongwa hweCCAC, ndiyo chete yakazara, kuyerwa-kwakavakirwa kushuma hurongwa hwechikamu chemafuta negesi, uye makambani ayo makumi manomwe nemana enhengo anomiririra mazhinji evashandisi vepasirese muchikamu chese cheukoshi, uye inodarika 74% yemafuta ese uye gasi kugadzirwa.

IMEO: Chirevo Chegore Chekutanga

Mumushumo wakaburitswa kuti uenderane nekutanga, IMEO yakaisa Theory yayo yekuchinja. Pamwoyo wedzidziso iyi kudiwa kwesangano rakazvimirira uye rinovimbika kuti ribatanidze aya akawanda masosi e data remarudzi akasiyana-siyana kuita dataset rakabatana uye rakakodzera. Chirevo ichi chinosanganisirawo kuongororwa kwemishumo yekutanga yakaunzwa nenhengo dzekambani yeOGMP 2.0. Mukati megore rino rekutanga, makambani mazhinji anoisa nhamburiko dzakakura mukuzivisa uye akatsanangura zvibodzwa zvekudzikisa 2025. Kubva pamakambani makumi mashanu neshanu anoisa zvinangwa, makumi matatu anosangana kana kudarika zvinokurudzirwa zvekudzikisa 55% kana pedyo-zero methane intensity, uye makumi mashanu neshanu vakaendesa zvirongwa zvekuvandudza kurongeka kwedata ravo mumakore matatu-30 anotevera.

Yakagarwa neUNEP, bhajeti reIMEO rinosvika ku100 miriyoni pamakore mashanu. Kuti ichengetedze rusununguko uye kuvimbika kwayo, haigamuchire mari yeindasitiri. Panzvimbo iyoyo, IMEO ichapihwa mari zvachose nehurumende uye philanthropies, nezviwanikwa zvepakati zvakapihwa neEuropean Commission senhengo yekutanga.

UNEP ndiyo inotungamira izwi repasi rose pane zvakatipoteredza. Inopa hutungamiri uye inokurudzira kudyidzana mukutarisira zvakatipoteredza nekukurudzira, kuzivisa uye kuita kuti nyika nevanhu vavandudze mararamiro avo pasina kukanganisa iyo yezvizvarwa zvinotevera.
