Survey-based summary of regulatory agencies’ programs to monitor and enforce compliance with vehicle emission and fuel consumption standards.

Describes trends in global ship activity and emissions for the years 2013 to 2015 and finds that emissions generally increased over this period, with efficiency improvements more than offset by increases in activity.

Addresses the opportunities for facilitating, and the barriers to financing, the transition to soot-free urban bus fleets in 20 megacities.

Examines how the greenhouse gas and fuel economy standards have changed over time, how the auto industry in different regions has reacted, and discusses how the standards may evolve in the future.

Estimates heavy fuel oil (HFO) use, HFO carriage, the use and carriage of other fuels, BC emissions, and emissions of other air and climate pollutants in the Arctic for the year 2015, with projections to 2020 and 2025.

Provides a roadmap to support the implementation of comprehensive clean fuel and vehicle policies in Southern and Western Africa.

Examines the benefits and costs of fuel-saving technologies for new heavy-duty vehicles (HDVs) in India over the next 10 years and, explores how various scenarios for the deployment of vehicles with these technologies will impact petroleum consumption and carbon dioxide (CO2) emissions over the next three decades.

Annual statistical portrait of technologies, fuel consumption, and GHG and pollutant emissions in Europe’s passenger car, light-commercial, and heavy-duty fleets.

Finds that fuel consumption of new aircraft designs could be cut by 25% in 2024 and 40% in 2034 using cost-effective emerging technologies—double the rate of improvement seen in designs coming from manufacturers now in response to market forces alone.

This study is an extension of ICCT’s work benchmarking U.S. airline fuel efficiency on domestic operations since 2010.
