US MARAD study finds marine use of natural gas substantially reduces some air pollutants and slightly reduces GHG emissions

Green Car Congress

A recently released total fuel cycle analysis for maritime case studies shows that natural gas fuels reduce some air quality pollutants substantially, and reduce major greenhouse gas (GHG) emissions slightly, when compared to conventional petroleum-based marine fuels (low-sulfur and high-sulfur). This is an important consideration.

Researchers predict average Gulf of Mexico hypoxic “dead zone” slightly above-average in Chesapeake Bay

Green Car Congress

The Chesapeake Bay prediction is based on models developed by NOAA­-sponsored researchers at the University of Maryland Center for Environmental Science, University of Michigan, and again relies on nutrient loading estimates from USGS.

Study Concludes That Use of Cellulosic Feedstocks to Meet US Biofuel Requirements Will Still Likely Result in Expansion of the Gulf Dead Zone

Green Car Congress

The findings suggest that an aggressive nutrient management strategy will be needed to reach the goal of a 5,000 km 2 areal extent of hypoxia set forth by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force even in the absence of biofuels, given current production to meet food, feed, and other industrial needs.

Along the way, it accumulates excess nutrients and pollutants before emptying into waterways, where it affects the health of fish, algae, and shellfish and contaminate drinking water and beaches. Either way, water resource managers need more accurate runoff estimates to plan better for the changes.
