carbon is an element, so "carbon" can't exist of anything.
But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
Carbon Most common in all fossil fuels is carbon. In natural gas, both hydrogen and carbon are common.
When fossil fuels are burned, carbon dioxide is released into the environment. This can influence the greenhouse effect and increase global warming. Coal is the fossil fuel that produces the most carbon dioxide emission.
Carbon
The gas released from the burning of fossil fuels that contributes to global warming is carbon dioxide (CO2).

Burning fossil fuels.
Carbon dioxide being given off when we burn fossil fuels.
The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.
Fossil fuels.
Most, if not all, roller coasters are powered by electricity. Most electricity is still being generated by burning of fossil fuels (coal, oil and natural gas). As this burning emits carbon dioxide you can clearly say that roller coasters are contributing to global warming by using fossil fuels.
Burning coal to generate electricity releases the most carbon dioxide of the fossil fuels.
