Adjusted C02 Emissions by Model Year

ENVIRONMENTAL PROTECTION AGENCYOverview of Long-Term TrendsWhile the most recent annual changes often receive the most public attention, the greatest value of the Trends database is to document long-term trends. This is because: 1) year-to-year variability can reflect short-term trends (two examples are the Cash for Clunkers rebates in 2009 and the impact of the tsunami […]

Interactive Map: Climate and Energy by State

Thursday, October 9th, 2014
Electricity Generation from Renewable Energy

Curious how your state stacks up when it comes to sustainability, renewable energy or climate-friendly policies? The Georgetown Climate Center’s new interactive map includes all these parameters (and much more) in its colorful, easy-to-read interface. With the center’s proprietary State Energy Analysis Tool as the engine, this map offers insight into a wide range of data that’s otherwise hard to come by, from Electricity Market Regulation to Energy Exporters and Importers. State profiles offer an in-depth analysis of each state’s energy/climate breakdown.

Health Benefits of Carbon Standards for Power Plants

Friday, October 3rd, 2014
Figure 1: The Co-Benefits of Carbon Standards Study

HARVARD SCHOOL OF PUBLIC HEALTH: CENTER FOR HEALTH AND THE GLOBAL ENVIRONMENT
SYRACUSE UNIVERSITY DEPARTMENT OF CIVIL & ENVIRONMENTAL ENGINEERING
BOSTON UNIVERSITY SCHOOL OF PUBLIC HEALTH
The U.S. Environmental Protection Agency (EPA) released the nation’s first-ever carbon pollution standards for existing power plants on June 2, 2014. The EPA-proposed Clean Power Plan would achieve a 30% reduction in carbon emissions from U.S. power plants below 2005 levels by 2030 (USEPA 2014a). Carbon dioxide (CO2) is an important greenhouse gas and a major driver of human-induced global climate change. Fossil-fuel-fired power plants are the single largest source of anthropogenic CO2 emissions in the U.S. They emitted 2.2 billion tons of CO2 in 2012 (AOE 2014) and currently account for 39 percent of total U.S. CO2 emissions (USEPA 2014b).

A Global High Shift Scenario: Impacts And Potential For More Public Transport, Walking, And Cycling With Lower Car Use

Figure 7: Total Urban Passenger Travel for Select Countries/Regions

INSTITUTE FOR TRANSPORTATION & DEVELOPMENT POLICY
UNIVERSITY OF CALIFORNIA, DAVIS
This report is the first study to examine how major changes in urban transport investments worldwide would affect urban passenger transport emissions as well as mobility by different income groups. It starts with the most recent United Nations urban population forecasts and the most recent model framework and forecasts used by the International Energy Agency (IEA) for global mobility modeling. The study extends these with new research on the extent of various urban passenger transport systems in cities across the world, as well as new estimates of the extent of mobility by non-motorized transport and low power e-bikes.

Renewable Energy in the Western States

ELECTRICITY GENERATION BY SOURCE, 2013

AMERICAN COUNCIL ON RENEWABLE ENERGY
With the growing prominence of renewable energy in the western power, heat, and transportation sectors, states are implementing and exploring technology and policy options to effectively manage its production and use. Renewable energy is now responsible for over 20% of electricity generation in six western states, and the region saw the addition of nearly 4 GW of new renewable energy capacity in 2013 alone – which is more than two thirds of total 2013 U.S. capacity additions.

#WomenInSTEM: Making a Cleaner Future

Mallory uses geographic information systems or GIS – a mapping software that she compares to “a real-life videogame” – to assess how various constraints, such as wetlands or an airport, may interact with potential renewable energy projects. Her aim is to site and design projects that can effectively co-exist with the surrounding environment.

Lansing, MI: Sustainable Construction on Moores River Drive

The Moores River Drive Project began in April of 2014. As a part of the project, the existing seawall will be removed and replaced with a sloping embankment along the shoreline. A pathway will also be installed along the embankment. Moores River Drive east of Waverly Road will be reconstructed from a four-lane boulevard to a two-lane road. Mt. Hope will be converted from a four-lane road to a three-lane road with bike lanes. The project will be complete in October 2014.

Performance of Alternatively Fueled Buses

Friday, September 5th, 2014
Figure 3-2. Comparison of performance and costs of 40-foot buses, diesel vs. hybrid.

NATIONAL CENTER FOR TRANSIT RESEARCH
Florida transit agencies have been dealing with volatile fuel prices and changes in regulations regarding diesel engines and fuel. In addition, emphasis on reducing the overall consumption of fossil fuels has increased, as well as reducing carbon emissions by transit agencies. Florida transit agencies and funding entities continue to be under pressure to reduce operating costs and to run a more sustainable and environmentally friendly fleet in the urban environment. A popular strategy to pursue these goals has been the acquisition of alternatively fueled buses. However, higher reliance on alternative fuels has increased both capital and operating costs for some fixed route operators, and has created challenges for the widespread adoption of advanced transit technologies.

Los Angeles: Eastside Transit Corridor Environmental Impact Study

Thursday, September 4th, 2014
Figure ES-1: Existing and Proposed Regional Metro Rail Lines (2035)

LOS ANGELES COUNTY METROPOLITAN TRANSPORTATION AUTHORITY
In addition to mobility benefits, the Eastside Transit Corridor Phase 2 Project would provide the project area with transportation, economic, land use, and environmental benefits. The analysis presented in this document shows that improved mobility to and from the project area has the potential to boost economic development in the project area and improve social justice by providing better access to employment, educational opportunities, and activity centers. Improved transit connectivity would increase transit ridership, which would also generate environmental benefits through reduced vehicle trips, less roadway congestion, and improved air quality.
