China is considering options for increasing fuel efficiency and reduce CO2 emissions from freight transportation. This study assesses the future costs of existing and emerging technologies to reduce fuel consumption and CO2 emissions of long‑haul tractor‑trailers in China. Economic impact metrics are investigated, including investment payback period, first-owner and full …
Brazil’s new PROCONVE P-8 standards will apply to all new on-road passenger and freight vehicles equipped with compression-ignition or spark-ignition engines and weighing at least 3,856 kg. These vehicle categories currently account for an outsized contribution to on-road vehicle emissions in Brazil. The P-8 standards will go into effect for …
The emissions reductions from the adoption of a new transportation technology depend on the emissions from the new technology relative to those from the displaced technology. Evaluate the emissions reductions from electric vehicles (EVs) by identifying which vehicles would have been purchased had EVs not been available. Do so by …
This briefing evaluates the compliance of manufacturer groups in India with fiscal year (FY) 2017–2018 fuel consumption standards and their readiness to meet more stringent requirements taking effect in FY 2022–2023. This analysis finds that the sale-weighted fleet average CO2 emissions in FY 2017-2018 from new passenger cars in India …
This working paper assesses technology progress and new developments in hybrid and electric vehicles in China. Joint ventures, especially with Japanese automakers, dominate China’s hybrid electric vehicle market. However, some independent domestic manufacturers have already made significant progress on full hybrid system development. Another promising direction is 48V mild hybrid …
California air regulators on Tuesday said they plan to keep tightening state vehicle emissions rules despite a Trump administration proposal last week that would strip the state of the ability to set its own limits. The California Air Resources Board (CARB) proposed maintaining strict Obama-era rules mandating rising fuel efficiency …
Acting U.S. EPA chief Andrew Wheeler told lawmakers on Wednesday he would welcome any deal between the auto industry and states like California that might result from a long-awaited Trump administration effort to roll back vehicle emission rules. The Trump administration’s proposal on vehicle fuel efficiency, which would roll back …
As a first-time effort in India, the Green Vehicle Rating (GVR) serves as a consumer information tool that identifies high to low performing vehicle models in 2 & 3-wheeler categories, in terms of the negative impacts of greenhouse gases and criteria pollutants released from the tail pipe. The rating is …
The Global Fuel Economy Initiative (GFEI) launched a report on its contribution to help individual countries work towards Sustainable Development Goal 7 (SDG7) at the United Nations High Level Political Forum (HLPF), in New York. The 2018 HLPF has the theme of “Transformation towards sustainable and resilient societies” and explores …
There is growing evidence globally and in China of the gap between laboratory test findings and real-world carbon dioxide (CO2) emissions and fuel consumption. Building on previous work, this project uses different sources of real-world CO2 emissions and fuel consumption data for light-duty vehicles (LDVs) to analyze real-world patterns in …
This briefing compares the fleet characteristics and fuel-efficiency technology deployment in China, Europe and the U.S. from 2010 to 2014. In addition, the briefing evaluates the response of the passenger vehicle market in China to the country’s fuel efficiency standards.
NEW DELHI: The government is set to tighten fuel efficiency norms for vehicles to push automobile manufacturers to expedite the conversion of conventional internal combustion engines (IECs) to electric vehicles (EVs). Sources said producing a certain share - about 4-6% - of their vehicles on electric mode will help them …
This analysis examines the potential of fuel-saving technologies for new heavy-duty vehicles (HDVs) in India less than 12 tonnes over the next 10 years. This is a follow-up study to research that completed for the greater than 12-tonne segment. Developed simulation models for two representative HDV types—a 12-tonne rigid truck, …
Heavy-duty vehicles in the European Union so far have not been subject to carbon dioxide emissions or fuel-consumption standards, making Europe the largest market without mandatory limits for such vehicles. However, the European Commission is preparing a regulatory proposal that would set mandatory CO2 limits for the heavy-duty vehicle (HDV) …
Plug-in electric vehicles (EVs) are well equipped to significantly increase the pace towards greater fuel efficiency, according to the latest Global Fuel Economy Initiative (GFEI) working paper. PEVs also present significant benefits in terms diversification of the transport energy mix, the reduction of local pollution and greenhouse gas emissions, as …
The ICCT commissioned the Institute for Internal Combustion Engines and Thermodynamics of the Graz University of Technology (TU Graz) to conduct track and chassis dynamometer testing to determine the aerodynamic drag, pollutant emissions, and fuel consumption of three European heavy-duty vehicles. Publicly available literature on the fuel consumption or European …
The US EPA is pursuing a rollback of earlier plans (implemented under Obama’s presidency) to raise the new-vehicle fuel-efficiency standard to nearly 50 miles per gallon by 2025 (that would be a fleet-level requirement, not model level). In response to that, 11 US states have now revealed an intention to …
The CO2 certification procedures for HDVs in the EU and the United Stated use a combination of component testing and vehicle simulation to assign official CO2 emission and fuel consumption values. This paper analyzes the model structure, simulation flow, and limitations of the regulatory simulation tool used in the EU …
The 2018 Toyota Camry incorporates eight technology upgrades that are specifically modelled in the U.S. Environmental Protection Agency’s Optimization Model for Reducing Emissions of Greenhouse Gases from Automobiles (OMEGA) and Lumped Parameter Model (LPM). This large number of simultaneous technology upgrades makes the Camry an excellent case study of how …
International climate talks in Paris set an ambitious goal: limiting global warming to 2°C by 2100. Reaching that goal will require investing an additional $1 trillion per year until 2050 in clean energy and other sustainability projects. But current investment levels are still far below that target level, which was …
