Engineered Carbon Sequestration Could Increase Other Pollutants in Ways that Trees Don’t

Washington, DC (August 13, 2008)- A new study by the International Journal of Greenhouse Gas Control suggested that burying carbon dioxide from coal-powered plants could increase other pollutants. This increase of other emissions is due primarily to the fact that carbon sequestration requires additional energy, new equipment, and new chemical reactions at the plants, which when using current technology releases extra pollutants.

“The decision to substantially reduce greenhouse gas emissions is going to be intertwined with decisions about how to deal with these other emissions,” said Jim Dooley of the Joint Global Change Research Institute in College Park, Maryland, and one of the lead authors for a major 2005 report on carbon sequestration by the Intergovernmental Panel on Climate Change.
The extra emissions include pollutants that cause acid rain, water pollution and destruction of the ozone layer. “Other studies mostly just look at one aspect, the carbon capture,” said study coauthor Joris Koornneef, an environmental scientist at Utrecht University in the Netherlands. “This is a first step in trying to quantify the [environmental] trade-offs.”
