A collection of useful numbers for quantifying the impacts of the human presence on Earth.

This quantity comes from a time series measurement and the most recent value (2015) is reported.


Value:		≈ 8.37 kg of waste / kg of coal see this value in other units This is equivalent to... ≈ 8.37 t of waste / t of coal
HuID:		39407
Relevant Year(s):		2015
Summary:		The global average mass (tonnes) of overburden/waste sediment moved per tonne of coal harvested in 2015. This ratio is termed the "stripping ratio" of coal and varies depending on how the coal mined.
Method:		This is a calculated quantity given commodity-level stripping ratios and the globally reported mass of coal mined by type.
