Financial Tribune - Thermal power plants have a small share in air pollution as almost all use gas, and emissions from gas combustion are way below those from other fossil fuels like diesel and mazut, says head of Economic, Social and Environmental Studies Office at the Renewable Energy and Energy Efficiency Organization (Satba).

�According to a 2017 report by Tehran Air Quality Control Company, power plants in the capital had a 5.3% share in greenhouse gas emissions,� IRNA quoted Reza Samadi as saying.

This share may be higher in other provinces because unlike Tehran power stations that have stopped using mazut, those in other cities such as the Bandar Abbas use this dirty fuel, he added.

Mazut accounted for 45% of total power plant feedstock in 2013, but declined to 8% in 2015.
