Fossil Fuel Subsidy Reform: From Rhetoric to Reality

Tuesday, December 1st, 2015
Value chain of production and consumption of fossil fuels (oil, gas and coal)

Despite this mounting evidence of the costs of fossil fuel subsidies, and the potential virtuous cycles that could result from their removal, governments are often reticent to undertake reform. Researchers have identified several specific reasons for the persistence of subsidies. Some of these are explicit, such as a lack of information, while others are implicit, driven by special interests.

A Global High Shift Cycling Scenario

Monday, November 16th, 2015
Bike Share Users on São Paulo’s New Bicycle Infrastructure. With these policies, governments will be able to quickly increase the amount of cycling, walking, and public transport use and achieve the benefits of an HSC scenario.

Cycling plays a major role in personal mobility around the world, but it could play a much bigger role. Given the convenience, health benefits, and affordability of bicycles, they could provide a far greater proportion of urban passenger transportation, helping reduce energy use and CO2 emissions worldwide. This report presents a new look at the future of cycling for urban transportation (rather than recreation), and the potential contribution it could make to mobility as well as sustainability.

Clean Power Plan Emissions Rate Goals: Projection of needed progress from 2020‐2030 (Source: EPA and SNL data)

BLACK & VEATCH Introduction On August 3, 2015, President Obama announced the Environmental Protection Agency’s (EPA) final Clean Power Plan (CPP) rule for reducing carbon dioxide (CO2) emissions from existing fossil fuel electric generating units (EGUs). The final rule establishes CO2 emission performance rates based upon the EPA’s determination of the best system of emission […]

Figure 2. Share of Ride-Sharable Trips Relative to Total Trips by Scenario

MINETA TRANSPORTATION INSTITUTE Executive Summary It is widely recognized that new vehicle and fuel technology is necessary, but not sufficient, to meet deep greenhouse gas (GHG) reductions goals for both the U.S. and the state of California. Demand management strategies (such as land use, transit, and auto pricing) are also needed to reduce passenger vehicle […]

Natural Gas & Pipeline Infrastructure: Impacts of the Clean Power Plan

Friday, September 4th, 2015
Figure 1. Projected U.S. Natural Gas Demand in AEE Institute Scenarios

The Environmental Protection Agency’s proposed Clean Power Plan (CPP) establishes state-by-state carbon emissions rate targets that it projects will reduce U.S. electricity sector carbon emissions 30% below 2005 levels by 2030. Some stakeholders, including the North American Electric Reliability Corp. (NERC), have raised concerns that states might rely heavily on natural gas generation for CPP compliance, creating stress on gas pipeline capacity and ultimately affecting electric system reliability. While it is likely that states will pursue a diverse portfolio of emission reductions, examining the infrastructure implications of gas use scenarios helps with risk management.

John Boesel

CALSTART, a non-profit member organization, has been expanding and supporting the clean transportation sector since 1992. Its president and CEO John Boesel checked in with TPR when zero-emission buses recently achieved a milestone. He gives readers a status report on advanced-bus technology and the market for these vehicles, as well as commenting on California regulators’ impact on the clean-vehicle industry in the state.

Low-Carbon Electricity Pathways for the U.S. and the South

Monday, August 3rd, 2015
Figure 1. The Proposed Emissions Rate Reduction Targets

Power plants are one of the largest sources of carbon pollution in the U.S., accounting for nearly 39% of annual CO2 emissions from the combustion of fossil fuels (EIA, 2014, Table A.18). On June 2, 2014, the U.S. Environmental Protection Agency (EPA) proposed state-specific limits on CO2 emissions from existing fossil fuel-fired electric generating units (EGUs) as part of its Clean Power Plan (CPP).

Washington, DC: Grinding to a Halt

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

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.
