Mining oil shale impacts the environment it can damage the biological land and ecosystems. The thermal heating and combustion generate a lot of material and waste that includes carbon dioxide and greenhouse gas. Many environmentalists are against the production and usage of oil shale because it creates large amounts of greenhouse gasses.

In addition, there have been many coal mining disasters, although work related coal deaths has declined substantially as safety measures have been enacted and underground mining has given up market share to surface mining. [citation needed] Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions.
The presence of this gas is well known from its occurrence in underground coal mining, where it presents a serious safety risk. Coalbed methane is distinct from a typical sandstone or other conventional gas reservoir, as the methane is stored within the coal by a process called adsorption. The methane is in a near-liquid state, lining the ...
Geological sequestration refers to the storage of CO 2 underground in depleted oil and gas reservoirs, saline formations, or deep, coal beds unsuitable for mining. [107] Once CO 2 is captured from a point source, such as a cement factory, [108] it can be compressed to ≈100 bar into a supercritical fluid.
Increases in levels of carbon dioxide – the main greenhouse gas – from 2020 to 2021 was larger than the average annual growth rate over the last decade, with concentrations reaching 415.7 ...
Surface mining of oil shale deposits causes the usual environmental impacts of open-pit mining. In addition, the combustion and thermal processing generate waste material, which must be disposed of, and harmful atmospheric emissions, including carbon dioxide, a major greenhouse gas.
Underground product gas is an alternative to natural gas and potentially offers cost savings by eliminating mining, transport, and solid waste. The expected cost savings could increase given higher coal prices driven by emissions trading , taxes, and other emissions reduction policies, e.g. the Australian Government's proposed Carbon Pollution ...
