How does calcium carbonate reduce harmful emissions from coal-fired power stations?
Coal contains sulphur and when this is burnt(heated) sulphur dioxide is produced, this is a greenhouse gas.

Then this acid sulphur is neutralized with calcium carbonate to form calcium sulphate, water and carbon dioxided
