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.

Compiles a high-resolution ship emissions inventory in the Greater Pearl River Delta (GPRD), a heavily populated and prosperous region with heavy ship traffic. Because this traffic contributes to poor local air quality, the Chinese government has identified the GPRD region as a key target for steps to control emissions from ships.

Despite the anticipated decline in diesel car sales future carbon dioxide (CO2) standards in the EU can still be met even if new-car diesel share falls as low as 15% by 2025. The net compliance cost for reaching a 70 g/km (NEDC) target by 2025 would decline by €10–€280 per vehicle, if the diesel market share were to drop to a level as low as 15%.
