Proposes engine-based standards coupled with a tire efficiency regulation as the best approach for the first phase of India's HDV efficiency standards. 


Emissions from on-road vehicles are a significant cause of air pollution in urban areas. Beijing, where air quality has historically been poor, is taking measures to reduce emissions from the transport sector.


Summarizes the new average fuel economy and greenhouse gas standards for light-duty vehicles that will phase in from 2016 through 2020.


Annual update to ICCT's ranking of U.S. airlines by fuel efficiency on domestic operations. The gap between most- and least-efficient airlines narrowed slightly to 25%, and overall industry fuel efficiency improved by 1.7%.


Examines the effect that tax and other incentives in the EU have had on CO2 emissions, and identifies a clear shift over time toward tax-optimized vehicles.


Characterizes six potential sources of indirect greenhouse gas emissions from crude oil and assesses the extent to which they are attributable to oil production.


Summarizes how state and local governments are supporting the development of local electric-vehicle markets in the 25 most-populous U.S. metropolitan areas. Provides a quantitative estimate of the effective cost of owning and operating battery electric vehicles in those 25 cities.


Proposes a rapid, comprehensive policy response not only to deal with defeat devices but also to identify vehicle models with high real-world emissions relative to test-cycle performance and improve current compliance and enforcement programs.


Surveys governments', automakers', and advocates' efforts to support development of the global EV market, and outlines an agenda to promote the global transition to a zero-emission vehicle fleet.


This annual update to the L2R series analyzes eleven data sources covering fourteen years, six countries, and almost 600,000 vehicles. In the EU the gap between official and real-world vehicle CO2 emissions grew to 38 percent in 2014.


Concisely sets forth the case for leapfrogging from BS IV to BS VI vehicle emissions standards in India, and states the ICCT's position in favor of expediting progress to Bharat VI.


Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly.


Analyzes the fuel efficiency / carbon intensity of new commercial aircraft, and indicates the substantial gap existing between what is technological feasible and new aircraft currently on the market.


Inspection and maintenance (I/M) programs are key to identifying high-emitting vehicles and mitigating their impact on air quality and climate. This paper assesses best practices for I/M programs targeting heavy-duty vehicles and makes recommendations on how to improve HDV I/M programs in the future.


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.


Analyzes the implications of a growing natural gas vehicle fleet on the emission benefits of the U.S. HDV “Phase 2” greenhouse gas rulemaking, synthesizing data on upstream emissions, vehicle emissions, and efficiency technology.


Surveys actions being taken by state and local governments and public utilities to facilitate electric vehicle deployment in the 25 largest U.S. metro areas. Presents city-specific analysis of consumer benefits and links between policies aimed at promoting EVs and market uptake.


Technical summary for policy makers of the status of hybrid vehicle development in the United States. First in a series of technical briefing papers on trends in energy efficiency of passenger vehicles in the U.S.


Summary based on the provisional data recently released by the European Environment Agency. All manufacturers have achieved their 2015 targets, with average emissions of 123.3 g/km in 2014, a decrease of 3% compared to 2013.


Presents results of studies on the EU crude oil market and GHG emissions, along with a model for lifecycle analysis of crude extraction and an estimate of carbon intensity of oil supplied to the European Union in 2010.
