The European Commission has published the first European Aviation Environmental Report, the result of close collaboration between the EC, the European Aviation Safety Agency (EASA), the European Environment Agency (EEA) and EUROCONTROL.

Road transport is an important source of both greenhouse gases and air pollutants. Despite improvements in vehicle efficiencies over past decades, today the sector is responsible for almost one fifth of Europe's greenhouse gas emissions.

The Department of Environment Affairs has completed the study to facilitate the large-scale uptake of alternative transport fuels in South Africa – the case for biogas.

The U.S. Environmental Protection Agency has released a report that explores key trends in carbon dioxide emissions, fuel economy, and technology usage related to model year 1975 through 2015 light-duty vehicles sold in the United States.

Vehicle Fuel Efficiency Labeling (VFEL) is used by numerous countries worldwide to improve the fuel efficiency of their transport fleets. The theory behind VFEL is that better-informed consumers are more likely to purchase fuel-efficient vehicles, and that market demand can improve the energy efficiency of the transport sector.
