Transitioning to Low-Carbon Trucks

Tuesday, June 16th, 2015
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.

Renewable Energy and Jobs: Annual Review 2015

Wednesday, May 27th, 2015
Figure 1. Renewable energy employment by technology

INTERNATIONAL RENEWABLE ENERGY AGENCY (IRENA)
IRENA estimates that renewable energy employed 7.7 million people, directly or indirectly, around the world in 2014(excluding large hydropower). This is an 18% increase from the number reported last year. In addition, IRENA conducted the first-ever global estimate of large hydropower employment, showing approximately 1.5 million direct jobs in the sector.

Tapping Iowa’s Wind Resources to Reduce CO2 Emissions

Thursday, May 7th, 2015
Of particular interest is the corollation especially observable in the 2010 – 2012 years, between the CO2

IOWA WIND ENERGY ASSOCIATION
In a conservative scenario it is estimated that Iowa wind could easily contribute a reduction of 15 million metric tons of carbon dioxide annually to the region outside of Iowa, and in a more optimistic but still moderate scenario Iowa’s contribution could easily be over 36 million metric tons annually.

Our Energy Tomorrow: The State of American Energy

Friday, January 9th, 2015
hydropower

America now occupies a position of energy leadership that was unthinkable a short time ago. Gone are the days of uncertainty and concern over having the supply of energy we need, when we need it. Today, the United States is the world’s top producer of natural gas, the world’s leading refiner of petroleum products, and very soon could be the leading producer of oil…But this is only part of America’s larger energy story. The United States is in the midst of a new era in domestic energy abundance characterized by rising use of renewable energy and increased oil and natural gas production that is strengthening our economic outlook and enabling America to emerge as a global energy superpower.

Strengthening the EPA’s Clean Power Plan

Thursday, October 23rd, 2014
FIGURE 1. The EPA’s Renewable Energy Targets under Its Proposed Clean Power Plan Are Modest

UNION OF CONCERNED SCIENTISTS
This brief outlines a better way to make the most of renewable energy in the Clean Power Plan, and to strengthen its state renewable energy targets as the cost of sources such as wind and solar power decline. The UCS proposal builds on the EPA’s approach while utilizing the latest available market data, demonstrated rates of growth in renewable energy, and existing state commitments to deploy renewables. Using our recommended modifications, the EPA could nearly double the amount of cost-effective renewable energy in their state targets—from 12 per-cent of total 2030 U.S. electric sales to 23 percent (Figure 1, p. 3).

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 […]

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.
