Statistical portrait of passenger car, light-commercial, and heavy-duty vehicle fleets in the European Union from 2001 to 2017


Survey of how features of Class 7 and 8 tractor trucks are specified for purchase in Canada and the United States


Analysis of the extension of the current CO2 certification procedure for heavy-duty vehicles, to also include trailers


Analysis of the market for new commercial trailers in the European Union in terms of sales by country, manufacturer, and trailer type and a survey of fuel-saving technologies.


New standards to reduce emissions from new on-road heavy-duty vehicles is part of Canada’s economy-wide commitment to reduce GHG emissions 30% by 2030.


Assessment of the health benefits and technology costs of the China VI emission standard.


Puts forward a number of specific recommendations aimed at improving the environmental outcomes of the European Commission's May 2018 proposed initial standards.


Summary of the China VI heavy-duty vehicle standards and a comparison with emission regulations in the other major markets.


Evaluates the costs incurred by manufacturers of diesel engines used in non-road vehicles and equipment for emission reduction technologies needed to comply with increasingly stringent standards.


This report assesses progress in 2018 toward implementing the Climate and Clean Air Coalition's global strategy to introduce low-sulfur fuels and cleaner diesel vehicles.


The European Commission recently released a regulatory proposal for setting the first ever CO2 emission standards for new heavy-duty vehicles sold in the European Union.


Under the Bharat Stage VI and V standards, India will achieve significant reductions of NOx and PM from agricultural tractors and construction equipment.


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.


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.


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.


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 model structure, simulation flow, and limitations of the EU’s regulatory tool for the simulation of heavy-duty vehicle fuel consumption. Compares the regulatory vehicle simulation tools used in the EU and the United States.
