Updates a benchmarking study of airlines' fuel efficiency in 2010. Overall, the fuel efficiency of U.S. airlines on domestic operations improved 2.3% from 2010 to 2012, not enough to meet U.S. greenhouse gas reduction goals, and the gap between best and worst did not change.
Overview of recent ICCT research on the integration of trailers into Phase 2 of the U.S. regulations covering heavy-duty vehicle fuel efficiency and greenhouse gas emissions.
Results of a 2013 collaboration with the North American Council for Freight Efficiency on a survey-based study aimed understanding how the market for efficiency technologies has evolved and identifying opportunities for capturing additional efficiencies.
Assesses a broad set of bioenergy pathways by comprehensively accounting for all major carbon sources and sinks, calculating carbon payback times, carbon intensities, and carbon savings.
Demonstrates that incentives for the production of biofuel from cellulosic wastes and residues through the EU Renewable Energy Directive could deliver carbon savings without the same level of indirect land use change or sustainability effects as biofuel from food commodities.
Combines an analysis employing a commonly used investment assessment tool, the capital assets pricing model, with an outline of minor changes to existing federal tax incentives could help unlock needed investment in cellulosic biofuels.
Summarizes the case for shifting to a footprint-based efficiency standard in China, and analyzes how compliance burdens on auto manufacturers might change.
Estimates availability of the cellulosic fraction of waste, agricultural residues, and forestry residues, while considering current uses of these materials and environmental impacts.
Fills a gap in the analysis behind U.S. and European regulations intended to restrict use of mobile air-conditioning refrigerants based on their global warming potential.
A novel analysis that connects 2011 in-use fleet characteristics, global satellite data on ship movement, and literature on ship technology to assess the long-term prospects for increasing shipping efficiency.
