Item Economic and Environmental Costs and Benefits of Living Snow Fences: Safety, Mobility, and Transportation Authority Benefits, Farmer Costs, and Carbon Impacts(Minnesota Department of Transportation, 2012-02) Wyatt, Gary; Zamora, Diomy; Smith, David; Schroeder, Sierra; Paudel, Dinesh; Knight, Joe; Kilberg, Don; Current, Dean; Gullickson, Dan; Taff, SteveBlowing and drifting snow on Minnesota's roadways is a transportation efficiency and safety concern. Establishing standing corn rows and living snow fences improves driver visibility, road surface conditions, and has the potential to lower costs of road maintenance as well as accidents attributed to blowing and drifting snow. It also has the potential to sequester carbon and avoid the carbon emissions of snow removal operations. In recent years the Minnesota Department of Transportation (MnDOT) has paid farmers to leave standing corn rows to protect identified snow problem roadways. They have paid farmers $1.50 per bushel above market price. With increasing demand for corn to fuel the ethanol industry, paying $1.50 per bushel above market price may not be sufficient incentive for leaving standing corn rows. Also, with MnDOT’s memorandum of understanding with USDA to plant living snow fences through the Conservation Reserve Program (CRP), now is an opportune time to review MnDOT’s annual payment structure to farmers and prepare a new one. This project has: 1) developed a calculator to estimate payments for farmers that includes consideration of safety and snow removal cost savings; 2) estimated potential income from carbon payments; 3) worked closely with MnDOT engineers and plow operators, estimated the safety and snow removal costs and carbon emissions avoided by MnDOT through establishing living snow fences; and 4) evaluated farmers’ willingness to establish living snow fences and identified farmers/landowners’ constraints to adoption. Data is provided to MnDOT to assist staff in its decision making related to their Living Snow Fence Program.Item Reducing Greenhouse Gas Emissions From Transportation Sources in Minnesota(University of Minnesota Center for Transportation Studies, 2008-06) Boies, Adam; Kittelson, David B.; Watts, Winthrop J.; Lucke, Jan; McGinnis, Laurie; Marshall, Julian; Patterson, Tyler; Nussbaum, Peter; Wilson, ElizabethThe 2007 Minnesota Next Generation Energy Act established goals for reducing statewide greenhouse gas (GHG) emissions by 15% by 2015, 30% by 2025, and 80% by 2050, relative to 2005 levels. This report investigates strategies for meeting those reductions in Minnesota?s transportation sector, which produces approximately 24% of total state GHG emissions. The study focuses on three types of emission-reduction strategies: those that improve vehicle fuel economy, those that reduce the number of vehicle-miles traveled, and others that decrease the carbon content of fuel. The researchers used a quantitative model to test the effectiveness of specific strategies for GHG emission reduction from transportation in Minnesota. Modeled scenario outcomes depend strongly on input assumptions, and lead us to the following three main conclusions. 1. Meeting state goals will require all three types of policies. For example, Minnesota could adopt a GHG emissions standard, a low-carbon fuel standard, and comprehensive transit and Smart Growth policies. 2. Technologies are available today to substantially improve fuel economy and vehicle GHG emissions. Requiring these technologies could save Minnesota consumers money and better insulate them from oil price volatility. 3. Changes in vehicle-miles traveled (VMT) have a strong impact on whether the goals can be met, and increases in VMT can offset GHG reductions. Overall, the research indicates that the goals can be met, but achieving them requires consistent and concerted action beginning immediately.Item A Smaller Carbon Footprint: Research Suggests Combining Strategies to Meet Legislative Goals in the Transportation Sector(University of Minnesota Center for Transportation Studies, 2008-06) Boies, Adam; Kittelson, David B.; Watts, Winthrop J.; Lucke, Jan; McGinnis, Laurie; Marshall, Julian; Nussbaum, Peter; Wilson, ElizabethThe 2007 Minnesota Next Generation Energy Act established goals for reducing statewide greenhouse gas (GHG) emissions by 15% by 2015, 30% by 2025, and 80% by 2050, relative to 2005 levels. This document summarizes a longer report which investigates strategies for meeting those reductions in Minnesota's transportation sector, which produces approximately 24% of total state GHG emissions.
