But there is another big concern about the use of LPG: its rising cost. The cost of 12kg of LPG spiked by 50% from 4,515 Nigerian Naira ($11/£8) in September 2020 to 6,165 Nigerian Naira ($16/£12) in September 2021, the National Bureau of Statistics says. In a report Eleri published this year on the growing clean cooking market, she recommended that the government bring in policies to keep the price low.
