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.


Compares passenger vehicle greenhouse gas and fuel economy standards from eight major countries, states, and regions. It finds that Japan and Europe are closely tied in the "race to the top" for the world's most efficient new passenger vehicle fleet, while the United States lags behind these two regions by a large margin.

Non-petroleum based fuels can have several advantages over gasoline and diesel in terms of energy diversity and security, control of greenhouse gas emissions, and reduced pollutant emissions. But in order to reap these benefits, care and attention must go into the production, distribution, and use of these fuels.
