Washington, DC: Grinding to a Halt

Thursday, July 23rd, 2015
Figure 1. Nonattainment with current (75 ppb) and proposed (65 ppb) ozone standards.

UNITED STATES CHAMBER OF COMMERCE
As Congress gears up to debate reauthorization of surface transportation programs, this report is intended to call attention to a significant emerging threat to addressing the aforementioned transportation challenges: the Environmental Protection Agency’s (EPA) forthcoming ozone national ambient air quality standards (NAAQS). This report analyzes the impact of these regulations on transportation projects, with a focus on the Washington, D.C. metropolitan area.

Benchmarking Air Emissions

Monday, July 20th, 2015
TABLE 1 100 Largest Electric Power Producers in the U.S. (in order of 2013 electric generation)

CERES
This report examines and compares the stack air pollutant emissions of the 100 largest power producers in the United States based on their 2013 generation, plant ownership, and emissions data. Table 1 lists the 100 largest power producers featured in this report ranked by their total electricity generation from fossil fuel, nuclear, and renewable energy facilities. These producers include public and private entities1 (collectively referred to as “companies” or “producers” in this report) that own roughly 2,800 power plants and account for 85 percent of reported electric generation and 87 percent of the industry’s reported emissions.

It’s Smart To Be Dense

It’s Smart To Be Dense

Urban density is fundamental principle of sustainable development. Density supports economic and creative vibrancy, social integration, and a healthy, environmental sustainable development model. As the world’s population continues to urbanize, our cities have two options for growth: densify or sprawl. The private-car dependent sprawl model of the 20th century must change, and move away from a reliance on private cars, to accommodate a more populous, and more prosperous world.

2015 U.S. Clean Tech Leadership Index

Thursday, July 9th, 2015
2015 TOP 10 STATES (INCLUDING HISTORICAL RANKINGS)

CLEAN EDGE
The United States has seen a significant shift in its energy landscape since Clean Edge began publishing its clean-tech leadership index five years ago. The transition to a clean tech and energy efficiency-based economy, based on the many indicators we track, is well underway. Solar and wind power, along with natural gas and energy efficiency, are now the mainstream choices for meeting the nation’s electricity needs; coal-fired and nuclear power, the dominant choices of the 20th century, have become the marginalized “alternatives.”

Transitioning to Low-Carbon Trucks

Figure ES-1. Required ZEV sales share to hit 80-in-50 target with no biofuels v. scenario with 60% biofuels blends by2050

NATIONAL CENTER FOR SUSTAINABLE TRANSPORTATION
UC DAVIS INSTITUTE OF TRANSPORTATION STUDIES
The United States and California have both made commitments to an 80% reduction in energy-related greenhouse gases (GHGs) from 1990 levels by 2050 in order to help stabilize atmospheric concentrations of greenhouse gases. These commitments do not specifically target transportation or an individual transport mode.

This white paper reviews previous studies and provides a new investigation into the feasibility of achieving an 80% reduction in CO2-equivalent (CO2e) GHG emissions in the United States and California from trucks in the 2050 time frame (“80-in-50”). We assess the technological and economic potential of achieving deep market penetrations of low-carbon vehicles and fuels, including vehicles operating on electricity, hydrogen, and biofuels.

Drinking Water & Fracking: Risk Assessment

Wednesday, June 10th, 2015

UNITED STATES ENVIRONMENTAL PROTECTION AGENCY
From our assessment, we conclude there are above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water resources. These mechanisms include water withdrawals in times of, or in areas with, low water availability; spills of hydraulic fracturing fluids and produced water; fracturing directly into underground drinking water resources; below ground migration of liquids and gases; and inadequate treatment and discharge of wastewater.

De-Carbonizing Power: Figure 1, 2 and 3

BLOOMBERG NEW ENERGY FINANCE
In 2015, the US could set new national records: for annual renewable build; for coal retirements; and for gas burn from the power sector. Meanwhile, electricity-related emissions could fall to their lowest levels since 1994. This Research Note examines our short-term forecasts for US power.
