Clear-cutting of tropical mangrove forests to create shrimp ponds and cattle pastures contributes significantly to the greenhouse gas effect, one of the leading causes of global warming, new research suggests.
A seven-year study, led by Oregon State University and the Center for International Forestry Research, spanned five countries across the topics from Indonesia to the Dominican Republic. The researchers concluded that mangrove conversion to agricultural uses resulted in a land-use carbon footprint of 1,440 pounds of carbon dioxide released into the atmosphere for the production of every pound of beef; and 1,603 pounds of released carbon dioxide for every pound of shrimp.
FutureMetrics recently published a white paper, titled “The Lowest Cost Solution for Maximum Decarbonization of the Power Sector While Maintaining Grid Reliability,” that compares two scenarios for powering carbon emissions in the power generation sector.
The first scenario assumes coal plants are retired and replaced with new combined cycle natural gas generation stations. The second assumes that existing pulverized coal plants are modified to use wood pellets rather than coal. Within the paper, author William Strauss notes his analysis shows converting coal plants to wood pellets is the solution that provides significantly higher carbon dioxide reduction at a lower net monetary cost per avoided ton.
