Mercury emissions from the US power stations have decreased between 2007 and 2008, while the worst emitting plants have shown an increase in emissions in the same period, according to a report.
According to a new report from the non-profit organisation Environmental Integrity Project (EIP), the six leading US power suppliers with three or more plants on the mercury emission list by total pounds include Luminant (formerly TXU), American Electric Power (AEP), Southern Company, Entergy, Ameren, and NRG.
EIP project senior attorney Ilan Levin said that the electric power industry has barely made a dent in its mercury emissions this decade.
“This slow progress is nowhere near the levels that would be achieved if all plants installed modern pollution controls,” Levin said.
Texas is home to the largest mercury emitter Luminant’s Martin Lake power plant, which reported almost a 5% increase from 2007 to 2008, according to the report.
Power plants in the US are responsible for over 40% of total mercury emissions.
