Ua ʻike mākou a pau hiki iā ʻoe ke mālama i hoʻokahi ton o ke kālā a me ka manawa ma ka paʻa ʻana he hālāwai pūnaewele. Maikaʻi wale ia - e hui i nā mea a pau ma ke kelepona a mālama i nā koina kinoea, nā kumukūʻai mokulele, ka manawa huakaʻi a me nā mea hou aku. He aha inā hiki iā ʻoe ke mālama i hoʻokahi tona o CO2 pū kekahi? ʻO nā hoʻokuʻu CO2, ʻoiai…
I kēia kakahiaka ua hana wau i kahi hoʻokolokolo. ʻIke ʻia ʻo nā hālāwai pūnaewele me nā lawelawe e like me Callbridge kahi ʻano ʻoluʻolu kūlohelohe. Over ma ahahealanibonotot.com ua paʻi lākou i ka Palapala GHG huahelu no ka lewa huakaʻi:
ʻO nā mokulele huki pōkole (ʻoi aku ma mua o 300 mile) hana i 0.64 lbs / mile o CO2 no kēlā me kēia mea holo.
Hoʻolālā nā lele huki waena (ma lalo o 1000 mile) i 0.44 lbs / mile o CO2 no kēlā me kēia mea holo.
ʻO nā mokulele huki lōʻihi (ʻoi aku ma mua o 1000 mile) hana i 0.39 lbs / mile o CO2 no kēlā me kēia mea holo.
No laila e ʻōlelo wau makemake wau i kahi hālāwai pūnaewele me kekahi ma Toronto (270 mile mai Ottawa), San Francisco (2900 mile mai Ottawa), a me Chicago (750 mile mai Ottawa). Inā mākou a pau i hui ma Ottawa ma kahi o ka pūnaewele, ʻo ka CO2 i hoʻokumu ʻia e kā mākou huakaʻi ea ʻo 270 × 0.64 + 750 × 0.44 + 2900 × 0.39 = 1634 lbs, a i ʻole 0.8 tone, o ka CO2.
No laila, he aha ka manaʻo? E hoʻokau iā ia i ke kuanaʻike, hana ka awelika ʻAmelika Hui Pū ʻIa i 20 mau tona o ka hoʻokuʻu ʻana o CO2 i hoʻokahi makahiki. Hoʻololi i nā huakaʻi he 4 a 5 paha i kēlā me kēia makahiki me nā hālāwai pūnaewele me Callbridge (a i ʻole kekahi lawelawe ʻē aʻe, no ia mea) hiki ke hōʻike i kahi hōʻemi 25% o nā hoʻokuʻu no kahi kanaka maʻamau.
Maʻemaʻe, ʻeā? A noʻonoʻo i ke kālā āu e mālama ai ...
