Evaluates the costs and benefits of using contracts for difference (CfDs) to support the production of bio-CNG from dairy farms in California.

This case study shows that the actual CO2 reductions of 18.6% achieved in the 2018 Camry exceed the 17.7% reductions predicted by EPA models. This confirms that the OMEGA and LPM models accurately predict both new technology benefits and synergies between technologies. It also suggests that other studies contradicting EPA model outcomes are inaccurate and underpredict future technology benefits.

Explores some of the compliance pathways available to heavy duty vehicle manufacturers. Specifically, this paper develops hypothetical technology packages for certain types of tractor trucks, vocational vehicles, and trailers using distinct technology strategies compares cost-effectiveness.


Comparative analysis of HDV sales in India in terms of manufacturer market share and vehicle characteristics. Additional discussion of engine attributes aimed at developing a categorization scheme.

Publication: Working paper

Analysis of testing and certification methods employed in HDV efficiency regulations worldwide, to identify test methods most appropriate for India's initial regulation in this policy area.

Investigates the contribution of black carbon from shipping to the global diesel black carbon inventory — 8% to 13% in 2010, a proportion that is not expected to decline under current and planned IMO policies.

Publication: Working paper

Presents an emissions inventory based on scenarios for growth in marine vessel traffic in the U.S. Arctic in 2025. At current fuel sulfur levels, pollutant emissions from ships in the region could increase 150%–600%.

Assesses the effect on technology innovation and deployment if mandatory CO2 standards in the EU were replaced by including road transport in the EU Emissions Trading System, as some have recently proposed.

Publication: Working paper

Guidelines for assessing non-fatal health impacts from vehicle pollution, including endpoint selection, incidence rate transfer, and considerations for economic valuation.

Publication: Working paper

Identifies and quantifies impacts on type-approval values of the EU's anticipated transition from the NEDC to the WLTP. Notably, the effects of the new driving cycle and the new definition of vehicle test masses result in a target of 100 g CO2/km for 2020.

Publication: Working paper

An assessment of long-term prospects for increasing the energy efficiency of tanker ships used to transport liquified natural gas, based on characteristics of the 2011 in-use LNG carrier fleet and global satellite data on ship movements.

Publication: Working paper

Results, methods, and underlying assumptions of an ICCT analysis conducted to support the decision-making process for updating NOM 044, demonstrating the cost-effectiveness of matching EPA 2010 or Euro VI requirements to reduce the environmental impacts of diesel heavy-duty vehicles.
