Coal: Social, environmental and economic concerns

Coal: social, environmental and economic concerns •Coking coal: derived from bituminous coal, by destructive distillation. It is hard and dark/greyish, it has few impurities and high carbon content and it is used particularly as a fuel in the industry (e.g. iron). •Steam coal: (also called thermal coal) all other hard coal that is not Coking coal.

Weak and strong sustainability Wikipedia

Although related subjects, sustainable development and sustainability are different concepts. Weak sustainability is an idea within environmental economics which states that 'human capital' can substitute 'natural capital'. It is based upon the work of Nobel Laureate Robert Solow, and John Hartwick. Contrary to weak sustainability, strong sustainability assumes that "human capital" and
