Documents the discrepancy between type-approval and real-world NOx emissions from new diesel passenger cars. On average, on-road NOx emissions from the vehicles tested for this analysis were about seven times higher than the limits set by the Euro 6 standard.
Extends an analysis of the gap between official and real-world fuel consumption and CO2 emissions for passenger cars in Europe, which reached 38% in 2013 and continues to grow at an accelerated pace.
Builds on recent research on the integration of trailers into HDV fuel consumption and GHG emissions regulations to conclude that the U.S. Phase 2 rule presents an opportunity to capture substantial and highly cost-effective efficiency gains from technology improvements.
Comparative analysis of interim progress reports from the industry teams participating in the SuperTruck program, showing all to be on schedule in reaching the program’s technology R&D and vehicle-efficiency goals.
Details differences in the fiscal policies used to support electric vehicle sales across eleven major auto markets. Tax exemptions and subsidies are playing a key role in spurring electric vehicle markets, but in widely divergent ways.
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.
