As Arctic shipping increases, pressure is mounting to protect the environment from fuels that are harmful when burned and spilled, including heavy fuel oil (HFO). Presently, the IMO is working to develop a ban on HFO in Arctic waters.

In January 2018, the city of São Paulo, Brazil, adopted Law 16.802, an amendment to its Climate Change Law that sets 10-year and 20-year targets for fleetwide reductions in tailpipe emissions of fossil carbon dioxide (CO2) and the air pollutants particulate matter (PM) and nitrogen oxides (NOx).

This paper estimates the environmental impacts of reintroducing commercial supersonic transport (SST) aircraft into the global aviation fleet. Model the landing and takeoff (LTO) noise, sonic boom, and carbon dioxide (CO2) emissions from a new, unconstrained SST network of 2,000 in 2035.

This report quantifies the gap in charging infrastructure to power more than 3 million expected electric vehicles by 2025. Based on the expected growth across the 100 most populous U.S. metropolitan areas, estimate the amount of charging of various types that will be needed to power these vehicles.

Aviation is widely seen as the transport sector that is most difficult to decarbonize. One option to dramatically reduce emissions within the aviation sector is through the use of low-carbon alternative fuels.

In a collaboration between Deutsche Gesellschaft für International Zusammenarbeit (GIZ) and the International Council on Clean Transportation (ICCT), this study reviews international experiences in public policies for electromobility in urban fleets and explores how they could be implemented in Brazil.

On December 17, 2018, representatives of the European Commission, the European Parliament, and the European Council agreed on a compromise for the European Union (EU) regulation setting binding carbon dioxide (CO2) emission targets for new passenger cars and light-commercial vehicles for 2025 and 2030.

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.
