In June 2019, Japan issued new fuel economy standards for passenger vehicles starting in model year 2030. The standards require an average fleet gasoline-equivalent fuel economy of 25.4 kilometers per liter by 2030, which is a 32.4% improvement over the fleet average for fiscal year 2016.

This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%.

This briefing paper reviews the benefit-cost estimate developed by the National Highway Traffic Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) to justify the Trump administration's August 2018 proposal to roll back the U.S. light-duty vehicle efficiency standards for 2020–2025.

In October of 2018, the Department of Transport of South Africa received cabinet-level approval to move the Green Transport Strategy (GTS) forward. The GTS is South Africa’s governmental guidance document that sheds light on pathways to decarbonize the country’s transport sector.

While the average fuel economy of vehicles continues to improve, the rate of progress has slowed in recent years.

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.

This report provides an overview of GFEI’s work globally, highlighting how improved vehicle fuel economy is vital for tackling climate change. It was published to coincide with the Global Climate Action Summit in San Francisco in September 2018.

Motorcycles are a dominant form of transport in many cities, especially throughout Asia. This Sourcebook describes the challenges of this trend and provides an overview on measures to counter the rising emissions from two-stroke two-and three-wheelers in developing cities.

The Trump administration's proposal to rollback national fuel economy standards was headed for its second public hearing a day after California officials and scores of speakers here blasted it as a
