    Every mining company has a unique GHG emissions footprint, depending on factors including geography, technologies used and commodities mined Scope 1 emissions are often driven by fugitive emissions (for example, when trapped methane and CO2 are released during coal mining) and by use of fossil fuels at the mine site (such as diesel use in trucks)Gypsum is a mineral that commonly precipitates in hydrothermal environments This study reports the electron microscopic analyses of gypsum morphologies and crystal sizes found in hot springs on the Kamchatka Peninsula, Russia, and compares these analyses with gypsum morphologies of hydrothermal genesis found in Lower Cambrian black shaleGypsum in modern Kamchatka volcanic hot springsThe objective of this study was to conduct a systematic review of published literature on ammonia (NH3) and enteric methane (CH4) emissions from beef and dairy cattle operations to obtain statistically representative emission factors based on dietary intakes of nutrients or energy, and to identify major causes of emissionAmmonia and Methane Emission Factors from Cattle
