FHWA with the support of AASHTO convened a peer exchange on current climate change adaptation activities and strategic needs in Schaumburg, Illinois, on December 8, 2009. This workshop included senior officials of state departments of transportation, FHWA headquarters and division offices and AASHTO. This report summarizes the results of the exchange, and is one of series of FHWA reports documenting the results of national peer exchanges on integrating climate change considerations into the transportation planning process.

State and Local News

Northeast and Mid-Atlantic States Launch Transportation and Climate Initiative. On June 16, 11 Northeast states and the District of Columbia launched a Transportation and Climate Change Initiative “to help reduce greenhouse gas emissions, minimize our transportation system’s reliance on high-carbon fuels, promote sustainable growth, address the challenges of vehicle-miles traveled and help build the clean energy economy.” More information and a copy of the signed declaration of intent are available on the Georgetown Climate Center website.

MassDOT Announces Comprehensive Sustainable Transportation Initiative. On June 2, MassDOT launched GreenDOT, an effort to incorporate sustainability into all of the DOT’s activities. The initiative has a goal of reducing GHG emissions by over 2 million tons by 2020. The DOT aims to combat climate change by measures such as balancing highway expansion projects with projects that promote biking, walking, public transit, and smart growth. The DOT will also make investments in a green fleet and renewable power. The policy directive includes an illustrative list of the initiatives that MassDOT is implementing to achieve the GreenDOT goals. For more information, see the MassDOT Policy Directive or the press release.

New York City Panel on Climate Change Releases Adaptation Resources. The NPCC has released Climate Change Adaptation in New York City: Building a Risk Management Response, to provide a “foundation” for climate change adaptation in New York City and tools to start formulating an adaptation response. The document includes a brief analysis of NYC’s transit system vulnerabilities. NPCC’s eight step Adaptation Assessment Guidebook is included as Appendix B. And a workbook on “Incorporating Climate Change into Design and Performance Standards” is Appendix C.

California Air Resources Board Releases Draft Regional GHG Reduction Targets. CARB has released the draft GHG emission reduction targets for passenger vehicles for the state’s 18 MPOs as part of the implementation of SB 375. The 2020 and 2035 targets are expressed in per capita ghg emissions range compared to 2005 levels. The targets were informed by scenario planning analyses. As most of the infrastructure decisions affecting the 2020 network have already been made, the nearer term targets are based largely on operational improvements. Many MPOs also adjusted their 2020 forecasts to take the economic downturn into account. The four largest MPOs have a draft 2020 reduction target of 5-10 percent.

Announcements

FHWA Seeks Pilot Locations For Climate Vulnerability/Risk Assessment. FHWA is soliciting interested DOTs and MPOs to partner with us in piloting approaches to conduct climate change vulnerability and risk assessments of transportation infrastructure. The purpose of the pilots is twofold; 1) to assist State DOTs and MPOs more quickly advance existing adaptation assessment activities and 2) to assist FHWA in “test-driving” the model. Based on the feedback received through the pilots, FHWA will revise and finalize the model for national application. It is anticipated that 3-4 awards will be made at approximately $200,000 to $300,000 each. By Federal statute, a 50% non-Federal match is required for these funds to be awarded to the pilot areas. In-kind contributions such as staffing can be counted towards the match requirement. Applications are due to the relevant FHWA Division Office by July 30. For more information, see the solicitation announcement and the conceptual model which will soon be available on the FHWA Climate Change Activities Webpage.

FTA Seeks Applicants for Greenhouse Gas and Energy Reduction Projects. FTA has $75 million in FY10 funds available in its Transit Investments for Greenhouse Gas and Energy Reduction (TIGGER) Program for grants to public agencies.

Obama Administration Officials Release Progress Report on Work of Climate Change Adaptation Task Force. On March 16, the CEQ, NOAA, and the Office of Science and Technology Policy released an interim progress report of the Interagency Climate Change Adaptation Task Force.  The report recommends key components to include in a national strategy on climate change adaptation.  It calls for a national adaptation strategy that has a “flexible, forward thinking approach” shifting away from using past conditions to predict the future.  It also calls for adaptation responses to be included in current U.S. government plans, processes and approaches, so that adaptation and resilience approaches become part of existing activities.  Comments on the report are being accepted through May 15.  For full text of the report and to submit a comment, see the Interagency Adaptation Task Force website.

FHWA Posts Study of State Climate Action Plans. This study, completed last summer, reviews progress on state climate action plans in all 50 states.  The report provides a basic summary and analysis of the data gathered on transportation emission reduction strategies. It also assesses the level of certainty in estimates of strategies’ impacts on GHG emissions.  The report, accompanying data spreadsheet, and summary PowerPoint presentation are available on the research page FHWA’s Climate Change Website.

NCHRP Publishes Study on Mechanisms for Integrating Transportation-Related Greenhouse Gas Reductions into Transportation Decision Making. This study provides a factual basis for State DOTs and MPOs to weigh alternatives for managing GHG emissions from transportation.  The report covers five dimensions of GHG management policy: geographic level of implementation, target metric, sources covered, reduction target base, and regulatory nature of target (voluntary or mandatory).  The web-only study is available here.

Social Cost of Carbon for Regulatory Impact Analysis. The “social cost of carbon” (SCC) is an estimate of the monetized damages associated with an incremental increase in carbon emissions in a given year. It is intended to include (but is not limited to) changes in net agricultural productivity, human health, property damages from increased flood risk, and the value of ecosystem services.  The estimates presented in the report are meant to allow agencies to incorporate the social benefits of reducing CO₂ emissions into cost-benefit analyses of regulatory actions that have small, or “marginal,” impacts on cumulative global emissions. The report assists agencies in complying with Executive Order 12866, which requires a cost-benefit analysis of intended regulation. DOT Participated in the interagency process that produced this document.  The report is available here.

State and Local News

Oregon Legislation Calls for a Statewide Transportation Strategy to Achieve Greenhouse Gas Emission Reduction Goals. On March 18, Oregon Governor Ted Kulongoski signed Senate Bill 1059 which calls for the Oregon Transportation Commission in consultation with MPOs, other state agencies, local governments, and other stakeholders to adopt a statewide transportation strategy to reduce GHG emissions. It also calls for the DOT and the Department of Land Conservation and Development to establish guidelines for alternative land use and transportation scenarios that may reduce GHGs.  The legislation also calls for the Department of Land Conservation to establish a light-duty vehicle GHG reduction target in each MPO Region.  Local governments within MPO areas will be required to consider how regional transportation plans could be altered to reduce GHG emission. Full details of the bill are providedhere.

North Carolina Holds Climate Change Adaptation Workshop.

2009 National Household Travel Survey (NHTS) data is published.  The Federal Highway Administration (FHWA) has been collecting national data on travel behavior of the American public for 40 years.  The NHTS dataset allows analysis of daily travel by all modes, all times of day, and for all purposes, including characteristics of the people traveling, their household, and their vehicles. The 2009 NHTS has data on the travel of 150,000 households – 1 million trips.  The report includes data from new or updated questions on hybrid/alternative-fuel vehicle use, alternate mode use, flexibility in work arrival time, telecommuting, mobility and disabilities, travel to school, internet deliveries to households, interstate use and tolling.  The NHTS website is a good source of information to help you with your program, planning, and policy work.  The site includes policy briefs on topics such as “The ‘Carbon Footprint’ of Daily Travel,” “Travel to School: The Distance Factor,” and “Working at Home—The Quiet Revolution.” For more information, contact FHWA’s Office of Policy and Information.

State and Local News

Local Governments Plan for Development of Land Vulnerable to Rising Sea Level. It is almost impossible to plan for sea level rise unless one knows whether a parcel of land will be given up to the sea, elevated with the rising sea, or protected – with a dike, for example. Through a multi-year $2 million study, the U.S. Environmental Protection Agency worked with local land use planners in 131 jurisdictions along the Atlantic coast from Massachusetts to Florida to map which areas are likely to be protected from rising sea level based on available planning data and existing government policies.  The Delaware Valley Regional Planning Commission in Philadelphia, the Coastal Regional Commission of Georgia, and four Florida regional planning commissions created sea level rise planning maps that divide coastal land into four categories: developed (shore protection almost certain), intermediate (shore protection likely), undeveloped (shore protection unlikely), and conservation (no shore protection), to help start the dialogue for communities interested in deciding what they should do.  An article in the scientific journal Environmental Research Letters summarizes the study.  State-specific summaries and GIS data are also available.

Analysis of Macroeconomic Effects of Michigan’s Climate Action Plan is Released. The analysis indicates that implementation of Michigan’s Plan would expand the state’s economy and cut household energy prices. The Plan recommends 54 multi-sector climate policy strategies.  Transportation-related strategies include Anti-Idling Technologies and Practices, Vehicle Purchase Incentives such as rebates, Mode Shift from Truck to Rail, Renewable Fuel Standard (biofuels goals), Transit, and Smart Growth/Land Use.  The analysis indicates that anti-idling technologies and practices will result in greater GHG emission reductions between 2009 and 2025 than transit or smart growth/land use strategies.

California Air Resources Board (CARB) Approves Climate Change Proposed Scoping Plan: A framework for change. The plan outlines strategies to reduce the State’s GHG emissions to 1990 levels by 2020.  It includes several measures related to transportation (see Emissions Reduction Measures, Regional Transportation-Related GHG Targets, pp. 47-51) and notes that the state has allocated resources for MPOs to initiate or augment comprehensive scenario planning, or Blueprint, efforts that engage a broad set of stakeholders at the local level on the impacts of land use and transportation choices (see the following article).  The plan notes co-benefits of reducing GHGs, such as air-quality-related public health benefits and local economic benefits.

California Releases Final 2009 Climate Adaptation Strategy. Multiple state agencies were involved in developing this multi-sector strategy to guide California in adapting to climate change impacts.  The strategy summarizes the science on climate change impacts in seven sectors, including Transportation and Energy Infrastructure, and provides recommendations on how to manage against those threats.  The strategy is in response to Gov. Schwarzenegger’s Executive Order S-13-08 requiring state agencies to identify how they can respond to rising temperatures, changing precipitation patterns, sea level rise, and extreme natural events.  The state’s adaptation strategy will be updated as new data become available.

A Guide to Transportation Decisionmaking is published. The FHWA and the Federal Transit Administration (FTA) created the guide to help the public understand how transportation decisions are made at the local, State, and national levels, and to encourage them to contribute their ideas. It updates the process through SAFETEA-LU and replaces the older A Citizen’s Guide to Transportation Decisionmaking.  To receive a hard copy, contact Brenda Kragh at Brenda.Kragh@dot.gov.

FYI

What’s the hubbub about public opinion polls on climate change all about, and why should we care?

Considering the views of the public and of other transportation stakeholders is an integral part of our Federal-aid highway program.  Recent polls have shown a sharp decline in the percentage of Americans who say there is solid evidence that global temperatures are rising (57% in October 2009 vs. 71% in April 2008 according to the Pew Research Center or who see global warming as a very serious problem (35% in October 2009 vs. 44% in April 2008).  Yale University and George Mason University (GMU) polling results indicate that “public concern about global warming, and public trust in a range of information sources, has dropped sharply over the past year” (see Climate Change in the American Mind: Americans’ global warming beliefs and attitudes in January 2010).

However, the relationship between public concern about or belief in climate change doesn’t seem to be reflected in whether or not they think action should be taken to reduce GHG emissions.  In the Pew survey, 50% favored setting limits and making companies pay for their “carbon” emissions even if this may lead to higher energy prices, while only 35% said they thought climate change was a very serious problem.

To get a clearer assessment of public opinion about climate change, it’s valuable to consider trends over the long term.  The longest running public opinion poll on the environment is the Gallup Environment poll, which has been conducted nationwide for more than 20 years.  Over that time public concern about the greenhouse effect/global warming has stayed fairly consistent, with 63% in 1988 who worried a great deal or a fair amount and, in 2009, 60% who worried a great deal or a fair amount.  When asked if they favored imposing mandatory controls on CO₂ emissions and other GHGs, in the 2003, 2006, and 2007 polls 75-79% of Americans said yes.  Even in the 2009 poll 70% said yes.  Similar to the recent Pew survey, 8-16% more Americans favored controlling GHG emissions than the percentage who worried a great deal or a fair amount about global warming. For the first time in the Gallup poll’s history, however, in 2009 the public favored economic growth vs. environmental protection by 51% to 42% (Gallup attributed this to the recession).  The Yale/GMU January 2010 poll showed this sentiment had rebounded to 63% favoring protecting the environment, even if it reduces economic growth, vs. 37% who favored economic growth, even if it leads to environmental problems (see Q244 in Climate Change in the American Mind: Public Support for Climate & Energy Policies in January 2010). More information will be posted on FHWA’s climate change website after Gallup’s March 2010 poll results are released.

Next month: We hear that EPA is about to officially release the MOVES model.  What is it and can it help transportation agencies to develop their GHG emissions’ baselines and inventories?

Errata: Based on input about our November/December newsletter, we have updated two of the articles.  The lead article on COP-15 now includes detail on DOT’s participation in Copenhagen.  Based on feedback from EPA, we have updated the FYI piece on cap-and-trade.

U.S. DOE and U.S. EPA announce the 2010 Fuel Economy Guide for model year 2010 vehicles. Each vehicle listing gives an estimated annual fuel cost, based on the vehicle’s MPG rating and national estimates for annual mileage and fuel prices. The online version of the guide allows consumers to input their local gasoline prices and typical driving habits to receive a personalized fuel cost estimate. Fuel efficiency is important for reducing CO2 and other GHGs. The top ten fuel economy leaders for 2010 include nine hybrid vehicles, from compact cars to SUVs.

World Resources Institute issues provisional GHG emissions reporting standard for public sector. The standard was developed in consultation with agencies from all levels of government and is supported by the Federal Energy Management Program within U.S. DOE and U.S. EPA. The standard includes guidance on how to apply GHG accounting principles to government operations at the federal, state and local level. The standard is compatible with the Local Government Operations Protocol recently adopted by The Climate Registry, ICLEI Local Governments for Sustainability (ICLEI), the California Air Resources Board (CARB) and California Climate Action Registry (CCAR). For questions or to submit comments on the standard, please email Stephen Russell or Mary Sotos at pspcomments@wri.org.

EESI publishes State Actions on Climate Change: A Focus on How Our Communities Grow, to encourage State, regional, and local governments to focus on land use reform as a key strategy for reducing GHG emissions. The publication is the result of collaboration with the American Planning Association to develop tools to assist planners. The study examined State and regional climate action plans for their inclusion of transportation, green building, and land use or “smart growth” practices and found that the plans cover a broad range of strategies, because each area has unique geographic and socioeconomic conditions. Of the three, transportation practices were the dominant feature, along with, to a lesser degree, green building policies. Some common transportation policies include adopting California’s vehicle emissions standard (the country’s most aggressive standard), creating more mass transit options, and providing incentives to lower VMT. Specific smart growth practices appeared to be the least likely component of the plans. A table at the end of the document shows some aspects of urban planning that are incorporated. Any GHG reduction targets adopted or regional climate action plans to which a state belongs are provided.

Simple Measures Can Yield Big GHG Cuts, Scientists Say in Proceedings of the National Academy of Sciences. Dr. Thomas Dietz, Michigan State University assistant vice president for environmental research, and his colleagues find that simple, voluntary activities such as routine vehicle maintenance, carpooling and trip chaining, eco-driving, and use of low-rolling-resistance tires can result in significant reductions in GHG emissions and, therefore, “deserve increased policy attention.” They examined 17 household action types in five behavioral categories. Adoption of these actions typically is the result of several policy tools and strong social marketing, the authors state. They estimate that if the behaviors became the norm across the nation it could save 123 million metric tons of carbon per year, equal to 7.4% of U.S. national emissions, within ten years with little or no reduction in household well-being. Their estimates are based on “how many families could reasonably be expected to take such measures if they were provided information, offered financial assistance and could interact with others doing so.”

Managing Our Coastal Zone in a Changing Climate: The Time to Act is Now Issued by the Parliament of the Commonwealth of Australia Provides Insights Relevant to U.S. The fact that many Australian coastal communities have single-access roads is an issue of grave concern to the Commonwealth. The report noted that evacuation routes were a significant factor in the extent of a July 2009 bushfire tragedy (“Black Saturday”). Dr. John Church, from [the Commonwealth Scientific and Industrial Research Organisation, Australia’s national science agency] pointed out that “sea-level-rise planning benchmarks need to be part of a risk management framework,” stating “We really have to move into a risk assessment framework…where we talk more about probabilities and the risks that we are prepared to take….One problem that we have is that planners tend to come to us and say, “How much do we need to allow for sea level rise?’ The retort I always give is, ‘What kind of risks do you want to take?’ I think this is a very important change in process that we need: to put the onus of the risk back onto the planners and the policymakers, not leave it to the scientists.’

State and Local News

Draft Pennsylvania Climate Action Plan released for comment. The plan contains 52 climate policy actions, which are estimated to reduce the Commonwealth’s GHG emissions by 95.6 million metric tons (a 36 percent reduction below year 2000 business-as-usual levels, 42% if recent state and federal actions are included) and to provide a net gain of $5.13 billion and 54,000 new jobs by 2020. The Plan does not address climate change adaptation. The GHG emissions inventory and projections, which cover 1990 to 2020, use “standardized methodology prescribed by the [EPA] and in accordance with international standards.” Transportation is the third largest source of GHG emissions in Pennsylvania (24% in 2000, of which gasoline-powered on-road vehicles accounted for about 64% and on-road diesel vehicles for 15%). Of all the sectors analyzed, GHG mitigation actions from transit and ground passenger transportation are projected to produce the second largest financial gain for the Commonwealth. The Land Use and Transportation work plan recommendations are listed in the following table.

¹NA in this column means “not applicable.” Work plan numbers 1,2, and 4 are recent state actions that are being implemented by the state; and the federal government will be implementing national vehicle GHG emissions and corporate average fuel economy (CAFE) standards starting in 2012.
²Because T-9 uses federal dollars exclusively, it should be noted that the cost figures for T-9 are calculations of how many federal dollars – not state dollars – would be required to implement the work plan.
³This cost per ton value excludes the emission reductions associated with the “Federal Vehicle GHG Emissions and CAFE Standards” since costs (savings) were not quantified for this recent federal action.
GHG = greenhouse gas; MMtCO₂e = million metrice tons of carbon dioxide equivalent; $/tCO₂e = dollars per metric ton of carbon dioxide equivalent; NPV = net present value; NQ = not quantified; PA = Pennsylvania; PAYD = Pay-As-You-Drive; CAFE = Corporate Average Fuel Economy.

Climate Change and Transportation in Maine published by MaineDOT. This white paper prepares MaineDOT to respond to the Governor’s call to evaluate climate change adaptation options and positions the agency to work with transportation stakeholders to evaluate short-term and long-term approaches to preparing for and adapting to climate change. Judy Gates, Director of MaineDOT’s Environmental Office said “…uncertainty [about long-range impacts due to climate change] can create paralysis in an agency charged with making and justifying long-term, fiscally-responsible decisions around the safety and efficiency of public travel. But the long life-cycles of most transportation infrastructure demand early preparation to protect significant tax payer investments…” The white paper includes a table showing how Maine’s current and proposed adaptation strategies compare to seven other States whose Climate Action Plans address adaptation (see below). The paper references the part of TRB’s Special Report 290: Potential Impacts of Climate Change on U.S. Transportation that discusses the Caltrans process of evaluating bridges for seismic retrofitting, in which TRB suggests that a similar approach could be used to screen and identify critical infrastructure that is vulnerable to the impacts of climate change. MaineDOT has already included climate change as a factor to be considered in future planning with an eye towards conducting technical, risk-based assessments such as California’s.

FYI

What is the United Nations Framework Convention on Climate Change (UNFCCC), the Convention? The Convention is an international treaty adopted in 1992 in Rio de Janeiro and ratified by almost all of the countries of the world, in which they agreed to undertake policies and measures to return their greenhouse gas emissions to 1990 levels by 2000. In 1997, all but two of the Convention signatories (the U.S. and Turkey) adopted an addition to the Convention, the Kyoto Protocol, which has specific binding GHG emission targets to be achieved in the 2008 – 2012 time period (which would have been 7% for the U.S.) The U.S. has not ratified the Protocol primarily because China and India are exempt from a numerical cap on their emissions. Below are data from the UNFCCC on trends in GHG emissions in industrialized countries (called Annex I Parties) that committed to voluntary GHG reductions under the Convention

Related news. Indian Environment and Forest Minister Jairam Ramesh and Chinese Minister for National Development and Reforms Xie Zhenhua signed a 5-year commitment for their countries to collaborate on GHG emission reduction programs, projects, technology development, and demonstration. The Ministers agreed to work together to protect and promote the interests of developing countries like China and India.

Recent Events

DOT’s National Highway Traffic Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) Propose Landmark Joint Regulations to Establish Light-Duty Vehicle Greenhouse Gas (GHG) Emission Standards and Corporate Average Fuel Economy Standards (CAFE). The proposed regulations, published in the Federal Register on September 28, 2009, have two goals: reduce GHG emissions and improve fuel economy. The proposal follows from the National Fuel Efficiency Policy announced by President Obama on May 19, 2009, responding to the country’s critical need to address global climate change and to reduce oil consumption. EPA is proposing the first-ever GHG emissions standards under the Clean Air Act; NHTSA is proposing CAFE standards under the Energy Policy and Conservation Act. These standards apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016 and would result in an overall fleet fuel economy of 35.5 mpg. Comments must be received on or before November 27, 2009. To read the proposed rulemaking and find out how to submit comments, go to http://edocket.access.gpo.gov/2009/E9-22516.htm. (See related article on trends in fuel economy from 1923-2006)

Climate Change Bill Introduced in the Senate. On September 30, Senators Kerry and Boxer introduced the Clean Energy Jobs and American Power Act “to create clean energy jobs, promote energy independence, reduce global warming pollution, and transition to a clean energy economy.” The bill would add two new sections (Titles VII and VIII) to the Clean Air Act, which would set declining limits on GHG emissions and establish a Pollution Reduction Investment (PRI) program, also known as cap-and-trade. The Act would require EPA to establish 1) GHG emission standards for new heavy-duty vehicles and engines, and for nonroad vehicles and engines and 2) to standardized emission models and related methodologies for States and MPOs. It would create an emissions reduction program, allowing DOT to provide grants to States and MPOs to help them reduce GHG emissions from the transportation sector. It would establish goals to reduce GHG emissions from the nation’s largest stationary sources-initially around 7,500 facilities that account for nearly three-quarters of U.S. carbon pollution-to 97% of 2005 levels by 2012, 80% by 2020, 58% by 2030, and 17% by 2050 (versus a reduction to 20% of 2005 GHG emissions by 2050 called for in the House bill, the American Security and Clean Energy Act, introduced by Congressmen Waxman and Markey, which passed the House on June 26, 2009). The Boxer-Kerry bill also would establish a National Climate Change Adaptation Program and require EPA to distribute formula-based funding to States for projects and activities that address impacts on coastal watersheds.

EPA Finalizes Nation’s First GHG Emissions’ Reporting System/Monitoring to Begin in 2010. On January 1, 2010, EPA will, for the first time, require large, stationary-source emitters of GHGs to begin collecting data under a new reporting system, which will cover approximately 85 percent of the nation’s GHG emissions and apply to roughly 10,000 facilities. The reporting system will provide a better understanding of where GHGs are coming from and will guide development of policies and programs to reduce emissions. The data will also allow businesses to track their emissions, compare them with those of similar facilities, and provide assistance in identifying cost-effective ways to reduce emissions in the future. Fossil fuel and industrial GHG suppliers, motor vehicle and engine manufacturers, and facilities that emit 25,000 metric tons or more of carbon dioxide equivalent (CO2e) per year will be required to report GHG emissions data to EPA annually. More information on the new reporting system and reporting requirements is available at:http://epa.gov/climatechange/emissions/ghgrulemaking.html. State and local officials interested in additional information about developing and implementing cost-effective climate and energy strategies that help further environmental goals and achieve public health and economic benefits may visit: http://epa.gov/cleanenergy/energy-programs/state-and-local/index.html.

U.S. Climate Envoy Elaborates on President Obama’s Speech at United Nations Climate Summit Regarding Climate Change and December U.N. Conference of Parties (COP15). Speaking at a White House press briefing after the President’s climate change speech at the U.N., Todd Stern, the U.S. climate envoy, said that the U.S. would still have a solid bargaining position in Copenhagen even if the Administration fails to push its own GHG legislation through Congress before the intergovernmental conference. “We would like to see the maximum possible progress… on our domestic legislation,” Stern said. “In the event that there’s not domestic legislation done by the time of Copenhagen, we will negotiate with that in mind. But certainly the most progress we can get would be helpful.” At the U.N., the President said that the major developing countries, where virtually all of the growth in emissions over the next 30 years is going to occur, also have to take actions. Elaborating on that Stern said “[The major developing countries] have to stand behind those actions to the same degree that the US and other developed countries do. The President is making that very clear. And that has not traditionally been the way that the climate change negotiations and the whole climate change international debate have gone on.” (See related “FYI” article.)

Driving and the Built Environment: The Effects of Compact Development on Motorized Travel, Energy Use, and CO2 Emissions (TRB Special Report 298) Published. This recently-released report examines the relationship between land development patterns and vehicle miles traveled (VMT) in the United States to assess whether petroleum use, and by extension GHG emissions, could be reduced by changes in the design of development patterns. The report estimates the contributions that changes in residential and mixed-use development patterns and transit investments could make in reducing VMT by 2030 and 2050, and the impact this could have in meeting future transportation-related GHG reduction goals. Increasing population and employment density in metropolitan areas could reduce vehicle travel, energy use, and CO2 emissions from less than 1 percent up to 11 percent by 2050 compared to a base case for household vehicle usage, depending on the assumptions used. Commissioned papers used by the committee to help develop Special Report 298 are available online. A four page summary of and a press release onthe report is also downloadable at http://books.nap.edu/catalog.php?record_id=12747&utm_medium=etmail&utm_source=National%20Academies%20Press&utm_campaign=NAP+mail+new+09.8.09&utm_content=Downloader&utm_term=. On Wednesday, October 21, TRB will be hosting a webinar to explore the findings of this congressionally-mandated study.

NSF Awards NCSE $1.67M Climate Change Education Grant. The National Council for Science and the Environment (NCSE) has been awarded a three-year grant of $1,666,820 by the National Science Foundation to create a nationwide cyber-enabled learning community for solutions to climate change to be known as CAMEL (Climate, Adaptation, and Mitigation e-Learning). CAMEL will engage experts in science, policy and decision-making, education, and assessment in the production of a virtual toolbox of curricular resources designed for teaching climate change causes, consequences, and solutions.The project was developed by theCouncil of Environmental Deans and Directors (CEDD), which is managed by NCSE. More information on CAMEL, including a PowerPoint presentation by principal investigator David Hassenzahl and a video thereof, can be found at the CEDD website (http://ncseonline.org/Updates/cms.cfm?id=3274).

U.S. Energy Information Administration (EIA) Releases Its Annual Energy Review (AER).The AER is EIA’s primary report of historical annual energy statistics. For many series, data begin with the year 1949. Included are data on total energy production, consumption, and trade; overviews of petroleum, natural gas, coal, electricity, nuclear energy, renewable energy, international energy, as well as financial and environmental indicators; and data unit conversion tables. Two especially interesting graphics are for Primary Energy Consumption by Source and Sector, 2008 (the most recent year for which data is available) and the Petroleum Overview, 1949-2008, which shows how closely petroleum consumption in the U.S. tracks with petroleum imports (see below).

Publications released by University of Michigan Transportation Research Institute, Ann Arbor, Michigan:

Effect of “Cash for Clunkers” Program on Overall Fuel Economy of Purchased New Vehicles. September 2009. Conclusions: Based on data from October 2007 through June 2009 and using unemployment rate and price of gasoline as predictors of the fuel economy, the program improved the average fuel economy of all vehicles purchased by 0.6 mpg in July 2009 and 0.7 mpg in August 2009.
Economic Indicators as Predictors of Number and Fuel Economy of Purchased New Vehicles. July 2009. Conclusions: During October 2007 through June 2009, average fuel economy of purchased light-duty vehicles improved by a substantial amount-1.1 mpg-as a result of unemployment and price of gasoline; however, significantly fewer vehicles were purchased as a result of unemployment. The price of gasoline did not reduce the number of vehicles purchased.
Recent Reductions in Carbon Dioxide Emissions from New Vehicles. July 2009. Conclusions: Improved fuel economy of purchased new vehicles and decrease in distances driven, resulted in lower CO2 emissions per driver from purchased new vehicles were lower in November 2007 through April 2009, when compared to October 2007. The greatest reduction in emissions-12%-occurred in July 2008. The reduction in April 2009 (the latest month examined) was 8%.
Mechanisms involved in recent large reductions in U.S. road fatalities. Injury Prevention, June 2009. Conclusion: One factor in the large reductions in U.S. road fatalities was the decrease in leisure driving related to the price of gasoline.
Fuel efficiency of vehicles on U.S. roads: 1923-2006. Energy Policy, 2009. Conclusions: Overall fleet fuel efficiency decreased from 14 mpg in 1923 to 11.9 mpg in 1973. Starting in 1974, efficiency increased rapidly to 16.9 mpg in 1991. Thereafter, improvements have been small, with efficiency reaching 17.2 mpg in 2006.

New Report Provides Authoritative Assessment of National, Regional Impacts of Global Climate Change Details Point to Potential Value of Early, Aggressive Action.

Climate change is already having visible impacts in the United States, and the choices we make now will determine the severity of its impacts in the future, according to a new and authoritative federal study assessing the current and anticipated domestic impacts of climate change.

The report, “Global Climate Change Impacts in the United States,” compiles years of scientific research and takes into account new data not available during the preparation of previous large national and global assessments. It was produced by a consortium of experts from 13 U.S. government science agencies and from several major universities and research institutes. With its production and review spanning Republican and Democratic administrations, it offers a valuable, objective scientific consensus on how climate change is affecting—and may further affect—the United States.

“This new report integrates the most up-to-date scientific findings into a comprehensive picture of the ongoing as well as expected future impacts of heat-trapping pollution on the climate experienced by Americans, region by region and sector by sector,” said John P. Holdren, Assistant to the President for Science and Technology and director of the White House Office of Science and Technology Policy. “It tells us why remedial action is needed sooner rather than later, as well as showing why that action must include both global emissions reductions to reduce the extent of climate change and local adaptation measures to reduce the damage from the changes that are no longer avoidable.”

Some key findings includes:

• Climate changes are underway in the United States and are projected to grow. Climate-related changes are already observed in the United States and its coastal waters. These include increases in heavy downpours, rising temperature and sea level, rapidly retreating glaciers, thawing permafrost, lengthening growing seasons, lengthening ice-free seasons in the ocean and on lakes and rivers, earlier snowmelt, and alterations in river flows. These changes are projected to grow.
• Crop and livestock production will be increasingly challenged. Agriculture is considered one of the sectors most adaptable to changes in climate. However, increased heat, pests, water stress, diseases, and weather extremes will pose adaptation challenges for crop and livestock production.
• Threats to human health will increase. Health impacts of climate change are related to heat stress, waterborne diseases, poor air quality, extreme weather events, and diseases transmitted by insects and rodents. Robust public health infrastructure can reduce the potential for negative impacts.
  

Here are the key messages of the report pertinent to Transportation:

• Sea-level rise and storm surge will increase the risk o • f major coastal impacts, including both temporary and permanent flooding of airports, roads, rail lines,and tunnels.
• Flooding from increasingly intense downpours will increase the risk of disruptions and delays in air, rail, and road transportation, and damage from mudslides in some areas.
• The increase in extreme heat will limit some transportation operations and cause pavement and track damage. Decreased extreme cold will provide some benefits such as reduced snow and ice removal costs.
• Increased intensity of strong hurricanes would lead to more evacuations, infrastructure damage and failure, and transportation interruptions.
• Arctic warming will continue to reduce sea ice, lengthening the ocean transport season, but also resulting in greater coastal erosion due to waves. Permafrost thaw in Alaska will damage infrastructure. The ice road season will become shorter.
