Mayiko ochulukirachulukira akuyesetsa kuteteza ndi kukonza chilengedwe: kuchepetsa kutulutsa mpweya wa kaboni mumlengalenga, kukonzanso zinthu, magwero a mphamvu zongowonjezwdwa, zinthu zoteteza chilengedwe, kuyendetsa magalimoto osakanizidwa. Maiko amasankhidwa chaka chilichonse (EPI), njira yomwe imayesa mphamvu za ndondomeko za chilengedwe za mayiko oposa 163 polimbana ndi kusintha kwa nyengo ndi kulimbikitsa kuteteza chilengedwe.
Chifukwa chake, mayiko asanu ndi awiri omwe ali okonda zachilengedwe padziko lapansi ndi awa:
7) France
Dzikoli likuchita ntchito yabwino kwambiri yoteteza chilengedwe pogwiritsa ntchito magetsi ongowonjezeranso. France ndi yochititsa chidwi kwambiri chifukwa chogwiritsa ntchito mafuta okhazikika, ulimi wachilengedwe komanso mphamvu yadzuwa. Boma la France likulimbikitsa kugwiritsa ntchito chomalizachi pochepetsa misonkho kwa omwe amagwiritsa ntchito magetsi opangira magetsi m'nyumba zawo. Dzikoli likukula mofulumira ntchito yomanga nyumba za udzu (njira yomanga nyumba zachilengedwe kuchokera ku midadada yomangidwa ndi udzu woponderezedwa).
6) Mauritius
Dziko lokhalo la ku Africa lomwe lili ndi chiwerengero chachikulu cha Eco-Performance Index. Boma la dzikoli limalimbikitsa kwambiri kugwiritsa ntchito zinthu zachilengedwe komanso kukonzanso zinthu. Dziko la Mauritius ndi lodzidalira kwambiri pakupanga magetsi amadzi.
5) Norway
Poyang’anizana ndi “zithumwa” za kutentha kwa dziko, Norway anakakamizika kuchitapo kanthu mwamsanga kuti ateteze chilengedwe. Asanakhazikitse mphamvu "zobiriwira", dziko la Norway linakhudzidwa kwambiri ndi kutentha kwa dziko chifukwa chakuti mbali yake ya kumpoto ili pafupi ndi Arctic yosungunuka.
4) Sweden
Dzikoli lili pamalo oyamba pankhani yosunga chilengedwe ndi zinthu zokhazikika. Kuwonjezera pa kugwiritsa ntchito zinthu zobiriwira, dzikoli linachita bwino kwambiri mu Index chifukwa cha chiwerengero cha anthu, zomwe zikupita patsogolo kuti zithetse mafuta oyaka mafuta pofika chaka cha 2020. Dziko la Sweden limadziwikanso chifukwa cha chitetezo chapadera cha nkhalango zake. Kutentha kumayambitsidwa m'dzikoli - biofuel, yomwe imapangidwa kuchokera ku zinyalala zamatabwa ndipo siziwononga chilengedwe. Mukawotcha ma pellets, kutentha kwambiri kumatulutsa katatu kuposa kugwiritsa ntchito nkhuni. Mpweya wa carbon dioxide umatulutsidwa pang’ono, ndipo phulusa lotsalalo lingagwiritsidwe ntchito monga fetereza m’minda ya m’nkhalango.
3) Costa Rica
Chitsanzo china chabwino cha dziko laling'ono lomwe likuchita zinthu zazikulu. Latin America Costa Rica yapita patsogolo kwambiri pakukhazikitsa mfundo za chilengedwe. Kwa mbali zambiri, dziko limagwiritsa ntchito mphamvu zomwe zimachokera kuzinthu zowonjezereka kuti zitsimikizire kuti zikugwira ntchito. Osati kale kwambiri, boma la Costa Rica lidakhazikitsa cholinga chofuna kusalowerera ndale pofika chaka cha 2021. Kukonzanso kwakukulu kwamitengo kukuchitika ndi mitengo yoposa 5 miliyoni yomwe yabzalidwa zaka 3-5 zapitazi. Kugwetsa nkhalango ndi chinthu chakale, ndipo boma likukhwimitsa zinthu pankhaniyi.
2) Switzerland
Dziko lachiwiri "lobiriwira" padziko lapansi, lomwe m'mbuyomu lidakhala loyamba. Boma ndi anthu achita bwino kwambiri pomanga anthu okhazikika. Kuwonjezera mphamvu zongowonjezwdwa ndi zinthu zachilengedwe wochezeka, maganizo a anthu pa kufunika kwa malo aukhondo. Magalimoto ndi oletsedwa m'mizinda ina, pomwe ena amakonda kuyenda panjinga.
1) Iceland
Masiku ano Iceland ndi dziko lokonda zachilengedwe padziko lonse lapansi. Ndi chikhalidwe chake chochititsa chidwi, anthu a ku Iceland apita patsogolo kwambiri pakugwiritsa ntchito mphamvu zobiriwira. Mwachitsanzo, amagwiritsidwa ntchito kwambiri popangira magetsi. Kutentha kofunikira kumakhudzidwa ndi kugwiritsa ntchito haidrojeni. Gwero lalikulu lamphamvu mdziko muno ndi mphamvu zongowonjezwdwa (geothermal ndi hydrogen), zomwe zimapitilira 82% ya mphamvu zonse zomwe zimagwiritsidwa ntchito. Dzikoli likuchita khama kwambiri kuti likhale lobiriwira 100%. Ndondomeko ya dziko imalimbikitsa kukonzanso, mafuta oyeretsera, zinthu zachilengedwe, komanso kuyendetsa galimoto pang'ono.
