The burning of coal is the most polluting method for producing electricity and the environmental impacts are considerable. Besides the production of greenhouse gases by burning coal, there are also many other harmful compounds released during this process. But environmental problems are not limited to the burning process. The extraction, transportation, storage and disposal of coal all create additional environmental issues. Watch video in link below

There is however differences in the amount of pollution caused by burning coal depending on the type of technology utilised. New coal-fired power station technology is emerging with the ability to reduce the amount of greenhouse gases and other harmful compounds released during the burning process. Integrated gasification combined cycle (IGCC) combustion is the realisation of this new technology and claims to significantly reduce harmful emissions. Despite the reductions in pollution from the use of IGCC technology, coal fired power stations will still have serious impacts on the environment.
