ABSTRACT
The case of coal reminds us of the “rose-and-thorn” syndrome. For instance, countries like China, India, USA and Poland cannot avoid using coal for generating energy. The mining, preparation, transport and combustion of coal severely pollute the environment (not only in the countries concerned, but also in the neighboring countries), and causes climate change on a global-scale. This section draws attention to technologies for maximizing the efficient use of coal and minimizing the environmental impact and carbon emissions.
