This paper estimates NOx emissions from merchant vessels in China’s coastal region from 2015 to 2030. The results indicate that merchant vessels have become a non-negligible source of NOx emissions, and if left unchecked, will become a prominent problem in the near future.

Measurement of exhaust emissions from in-use vehicles is key to any effective system for controlling air pollution in the transportation sector. The best-known method of in-use vehicle emissions testing employs a portable emissions measurement system, or PEMS.

Transport emissions of carbon dioxide (CO2) have not decreased nearly as much as CO2 from all other sectors in Europe. Together with emission limits, taxes can help accelerate reductions by giving consumers incentives for buying low-emission vehicles, creating a market-pull effect.

The European vehicle market statistics pocketbook offers a statistical portrait of passenger car and light commercial vehicle fleets in the European Union, updated annually. The emphasis is on vehicle technologies and emissions of greenhouse gases and other air pollutants.

This update provides details on the latest policy measures that six select European Union member states (Denmark, Germany, Italy, the Netherlands, Sweden, the United Kingdom) are taking to support the deployment of advanced alternative fuels.

The European Union (EU) will continue incentivizing the use of biofuels and other renewable fuels through its recast Renewable Energy Directive for 2021-2030 (RED II).

Renewable methane could conceivably displace natural gas for use in existing vehicle fleets, reducing greenhouse gas (GHG) emissions as well as emissions of air pollutants like NOx. It is important that policy makers assess the realistic potential for renewable methane.

In this briefing, highlight the continued growth in electric vehicle uptake in leading markets, focusing on the 25 metropolitan areas in the world with the highest cumulative passenger electric vehicle sales.

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.

Heavy-duty vehicles (HDVs) are currently responsible for about one-fourth of fuel consumption and greenhouse gas emissions from the transport sector in the European Union. Within the HDV sector in the EU, tractor-trailers represent the largest share of CO2, accounting for roughly 70% of emissions.
