Most of the gas and coal produced today is used for power generation and as a source of heat for industry and buildings. Our detailed estimates, taking into account both CO 2 and methane, show a wide variation across different sources of coal and gas. Nonetheless, an estimated 98% of gas consumed today has a lower lifecycle emissions intensity ...
