The consumption of coal results in negative environmental impacts. Despite these adverse effects, coal is a significant energy source in the improvement of countries. However, modern technology can be used for cleaner coal. The quality of the coal can be increased with advanced technologies. These advanced technologies build an integral part of sustainable energy and clean coal technology (CCT) programs developed to meet the needs of globalization. This study summarizes developing techniques and technologies in decreasing pollutions from utilizing coal more efficiently. This paper presents information for scientists and engineers to select more cost-effective and environmentally friendly technologies of coal.
