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).

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.

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.

Diesel engines used to power non-road equipment and vehicles, such as agricultural tractors and construction equipment, are a significant source of air pollutant emissions.

This report provides a comprehensive overview of vehicle remote sensing, an emissions measurement technique which has been used for more than 25 years to evaluate emissions from passing motor vehicles in real-world driving.

Urban transit bus fleets are a significant source of air pollutant emissions, including black carbon, a harmful ultrafine particle and potent short-lived climate pollutant. Transit bus fleets are therefore an important target for accelerated transitions to clean engine technologies and fuels.

This paper aims to inform the next phase of PROCONVE for LD vehicles by assessing important components of PROCONVE L6 and their relative strengths and weaknesses compared with similar programs in the United States and the European Union. The U.S.

The market for agricultural tractors and construction equipment in India is growing rapidly. Without further regulatory action to control emissions from these sources, they are expected to surpass on-road vehicles as the predominant transportation-related source of particulate matter (PM) and nitrogen oxides (NOx) in the next 10-15 years.

The European Commission has proposed the world’s toughest emission standards for non-road mobile machinery (NRMM), which will tighten restrictions and set stricter limits on emissions of particulate matter (PM). The Stage V emission standards will phase in as early as 2018 for approval of new engine types, and in 2019 for all sales.

This working paper details the differences in fuel specifications for commercial gasoline and diesel fuels in India and the EU, and assesses potential air pollutant emission impacts of these differences.
