India has a substantial opportunity to improve HDV fuel efficiency levels. Per-vehicle fuel consumption reductions between roughly 20% and 35% are possible with technologies that are expected to be available in India over the next 10 years.


This position brief makes specific recommendations regarding the adoption of RDE testing in India. The recommendations are geared towards ensuring that implementation of an Indian RDE program would narrow the gap between laboratory and on-road emissions performance of vehicles that should meet Bharat Stage (BS) VI emissions standards. 


Summarizes the key elements of both new regulations (the new type-approval framework and amendment to regulation EU 2017/1151) and provides references for further reading for those interested in more details.


Assesses where electric vehicles and their batteries are manufactured and sold, and the underlying policies in place to sustain growth in the new technology around the world.


Experimentally investigates the fuel consumption of a best-in-class tractor-trailer in the United States through chassis dynamometer and track testing.


Summarizes the results of a pioneering vehicle testing program aimed at comparing the fuel efficiency of selected tractor-trailers in Europe and the United States.


Summarizes the state of the electric vehicle market development in California through 2017, quantifying growth across California cities, comparing that growth with other US markets, and putting it in context with broader California policy goals.


A regulatory proposal in the European Union would set mandatory CO2 limits for the heavy-duty vehicle (HDV) categories with the highest share of emissions. This breifing summarizes key findings and policy recommendations from recent ICCT research, including technology baseline and cost-effective CO2 reduction potential for long-haul tractor-trailers, the highest-emitting vehicle category.


This study observes the passenger car fleet’s characteristics and technology changes, including the development speed of major efficiency technologies, by 2014 in response to the China Phase III fuel standards.


Provides an overview of this strategy, which represents the first global climate framework for shipping, and includes quantitative GHG reduction targets through 2050 as well as a list of candidate short-, mid-, and long-term policy measures to help achieve these targets.


Reviews the impact of mid-level biodiesel blends on materials and emissions in conventional diesel vehicles in the Indonesian context.


Focuses on the new energy passenger vehicle market in China's cities, evaluates the implementation and effectiveness of local incentive policies, and analyzes the potential of future sustainability.


Analyzes the Canadian vehicle manufacturing market and sales patterns to illuminate the possible impacts if Canada weakens its greenhouse gas emission standards in order to align with the U.S. federal government or maintains its existing standards and aligns with California and, most likely, 13 other U.S. states and the District of Columbia.


Following a similar move by Beijing, 27 cities in China implemented stringent new vehicle fuel standards in October 2017 as a step toward reducing air pollution in heavily populated areas. These cities put the China VI fuel requirements into effect about 15 months before the national deadline and applied the new fuel standard to non-road equipment ahead of the national schedule.


Experimentally investigates the fuel consumption, pollutant emissions and aerodynamic performance of three European heavy-duty vehicles through chassis dynamometer and track testing.


Fact sheet for study that investigates the fuel consumption, pollutant emissions and aerodynamic performance of three European heavy-duty vehicles through chassis dynamometer and track testing.


An analysis of the state of autonomous trucking technology, including the benefits and drawbacks of adoption, and the impact on fuel use and emissions in the on-road freight sector.


Analyzes the U.S. off-cycle credit program within the 2025 greenhouse gas and fuel economy regulations, including how the off-cycle credits were used in model years 2015 and 2016, trends among automakers with the most credits, and the impact of greater credit use through 2025.


Ramping up HEFA+ deployment in aviation would likely create competition for feedstocks between aviation and renewable diesel in the road sector. It could also result in indirect land-use change from the increased use of food crops to create renewable diesel and HEFA+, thereby undermining the climate benefits of AJF deployment. 


In the aftermath of Dieselgate, diesel car sales shares are falling in Europe. But diesel's decline does not put EU CO2 targets out of reach. Other technologies offer more compelling and cost-effective pathways to reducing CO2 emissions from passenger cars.
