This week’s On the Radio segment looks at the Iowa DNR’s 2013 Greenhouse Gas inventory, which shows that Iowa’s agriculture industry is now the leading contributor to greenhouse gas emissions for the state. Listen to the audio below, or continue reading for the transcript.

Agriculture is now the number one contributor to greenhouse gas emissions in Iowa.

This is the Iowa Environmental Focus.

The Iowa Department of Natural Resourcesʼ 2013 Greenhouse Gas inventory report
found that Iowaʼs agriculture industry contributes to 27 percent of the stateʼs
greenhouse gas emissions.

The figure is due in part to Iowaʼs increasing dependence on wind energy, which has
drastically decreased the need for coal use over the last decade and brought emissions
from electric power generation down to 25 percent.

Greenhouse gas emissions from agriculture include those from animal digestive
systems, plant fertilizers and agricultural runoff. The most common of these gases are
methane and nitrous oxide.

Although agricultural emissions increased last year, Iowaʼs total emissions have now
decreased for three straight years.
