Mmefu ego carbon
Mmefu ego carbon bụ "ọnụ ọgụgụ kachasị elu nke ikuku carbon dioxide (CO2) nke sitere n'aka mmadụ zuru ụwa ọnụ nke ga-eme ka okpomọkụ ụwa dị na ọkwa a nyere ya na ohere, na-eburu n'uche mmetụta nke ndị ọzọ na-eme ka ihu igwe pụta". Mgbe egosipụtara n'ihe gbasara oge tupu ụlọ ọrụ emebere ya, a na-akpọ ya mkpokọta mmefu ego carbon, ma mgbe egosipụtara ya site na ụbọchị akọwapụtara nso nso a, a na-akpọ ya mmefu ego carbon fọdụrụ.
