What fossil fuel usage will result in no change in atmospheric co2 each year gizmo?

The answer is carbon dioxide

Carbon Dioxide (CO₂)

Explanation: Carbon Dioxide (CO₂) is released when any fossil fuel is burnt. This can be controlled by making minimum use of it. If the amount of fossil fuel burning is reduced, then it can help in reducing the atmospheric CO₂ upto a certain extent. Thus, fossil fuel must be use in limited way and also its alternatives must be used.
