Book Description
Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.
Reducing Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two

Book Description
Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. This study is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report provided a series of findings and recommendations on the development of regulations for reducing fuel consumption of MHDVs. On September 15, 2011, NHTSA and EPA finalized joint Phase I rules to establish a comprehensive Heavy-Duty National Program to reduce greenhouse gas emissions and fuel consumption for on-road medium- and heavy-duty vehicles. As NHTSA and EPA began working on a second round of standards, the National Academies issued another report, Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two: First Report, providing recommendations for the Phase II standards. This third and final report focuses on a possible third phase of regulations to be promulgated by these agencies in the next decade.
Legal Pathways to Deep Decarbonization in the United States

Book Description
Legal Pathways to Deep Decarbonization in the United States provides a "legal playbook" for deep decarbonization in the United States, identifying well over 1,000 legal options for enabling the United States to address one of the greatest problems facing this country and the rest of humanity. The book is based on two reports by the Deep Decarbonization Pathways Project (DDPP) that explain technical and policy pathways for reducing U.S. greenhouse gas emissions by at least 80% from 1990 levels by 2050. This 80x50 target and similarly aggressive carbon abatement goals are often referred to as deep decarbonization, distinguished because it requires systemic changes to the energy economy. Legal Pathways explains the DDPP reports and then addresses in detail 35 different topics in as many chapters. These 35 chapters cover energy efficiency, conservation, and fuel switching; electricity decarbonization; fuel decarbonization; carbon capture and negative emissions; non-carbon dioxide climate pollutants; and a variety of cross-cutting issues. The legal options involve federal, state, and local law, as well as private governance. Authors were asked to include all options, even if they do not now seem politically realistic or likely, giving Legal Pathways not just immediate value, but also value over time. While both the scale and complexity of deep decarbonization are enormous, this book has a simple message: deep decarbonization is achievable in the United States using laws that exist or could be enacted. These legal tools can be used with significant economic, social, environmental, and national security benefits. Book Reviews "A growing chorus of Americans understand that climate change is the biggest public health, economic, and national security challenge our families have ever faced and they rightly ask, ''What can anyone do?'' Well, this book makes that answer very clear: we can do a lot as individuals, businesses, communities, cities, states, and the federal government to fight climate change. The legal pathways are many and the barriers are not insurmountable. In short, the time is now to dig deep and decarbonize." --Gina McCarthy, Former U.S. Environmental Protection Agency Administrator "Legal Pathways to Deep Decarbonization in the United States sets forth over 1,000 solutions for federal, state, local, and private actors to tackle climate change. This book also makes the math for Congress clear: with hundreds of policy options and 12 years to stop the worst impacts of climate change, now is the time to find a path forward." --Sheldon Whitehouse, U.S. Senator, Rhode Island "This superb work comes at a critical time in the history of our planet. As we increasingly face the threat and reality of climate change and its inevitable impact on our most vulnerable populations, this book provides the best and most current thinking on viable options for the future to address and ameliorate a vexing, worldwide challenge of extraordinary magnitude. Michael Gerrard and John Dernbach are two of the most distinguished academicians in the country on these issues, and they have assembled leading scholars and practitioners to provide a possible path forward. With 35 chapters and over 1,000 legal options, the book is like a menu of offerings for public consumption, showing that real actions can be taken, now and in the future, to achieve deep decarbonization. I recommend the book highly." --John C. Cruden, Past Assistant Attorney General, Environment and Natural Resources Division, U.S. Department of Justice "This book proves that we already know what to do about climate change, if only we had the will to do it. The path to decarbonization depends as much on removing legal impediments and changing outdated incentive systems as it does on imposing new regulations. There are ideas here for every sector of the economy, for every level of government, and for business and nongovernmental organizations, too, all of which should be on the table for any serious country facing the most serious of challenges. By giving us a sense of the possible, Gerrard and Dernbach and their fine authors seem to be saying two things: (1) do something; and (2) it''s possible. What a timely message, and what a great collection." --Jody Freeman, Archibald Cox Professor of Law and Founding Director of the Harvard Law School Environmental and Energy Law Program

Book Description
"The projections in the U.S. Energy Information Administration's (EIA's) Annual Energy Outlook 2012 (AEO2012) focus on the factors that shape the U.S. energy system over the long term. Under the assumption that current laws and regulations remain unchanged throughout the projections, the AEO2012 Reference case provides the basis for examination and discussion of energy production, consumption, technology, and market trends and the direction they may take in the future. It also serves as a starting point for analysis of potential changes in energy policies. But AEO2012 is not limited to the Reference case. It also includes 29 alternative cases (see Appendix E, Table E1), which explore important areas of uncertainty for markets, technologies, and policies in the U.S. energy economy. Many of the implications of the alternative cases are discussed in the 'Issues in focus' section of this report. / Key results highlighted in AEO2012 include continued modest growth in demand for energy over the next 25 years and increased domestic crude oil and natural gas production, largely driven by rising production from tight oil and shale resources. As a result, U.S. reliance on imported oil is reduced; domestic production of natural gas exceeds consumption, allowing for net exports; a growing share of U.S. electric power generation is met with natural gas and renewables; and energy-related carbon dioxide emissions remain below their 2005 level from 2010 to 2035, even in the absence of new Federal policies designed to mitigate greenhouse gas (GHG) emissions."--Executive Summary (p. 2).
