Question

Production and delivery of natural gas may emit more CO2 and CH4 per unit of energy produced than the burning of coal for commercial energy.​

Quizplus · Accepted Answer

Although natural gas is a cleaner burning fuel compared to coal, the production and delivery of natural gas may release significant amounts of methane (CH4), a potent greenhouse gas, into the atmosphere. Studies have shown that the total emissions from natural gas production and transportation may outweigh the emissions from burning coal, especially in the case of shale gas extraction through hydraulic fracturing ("fracking").
