What is the main reason for coal liquefaction?

Coal liquefaction, any process of turning coal into liquid products resembling crude oil.

Why is coal bad for the environment?

The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion.
