Almost three-quarters of Londoners support charging drivers of dirty vehicles in an effort to tackle the capital’s air pollution crisis, according to a study.

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).

NOx emissions from diesel cars in the EU have remained high, largely due to a growing gap between emission certification limits of Euro 4 and Euro 5 standards (measured in laboratory testing) and “real-world” emissions of diesel cars operating on the roads.

This briefing paper identifies key differences in the regulations governing certification of NOX emissions from diesel cars (Euro 6) and trucks (Euro VI) that help explain

First Low Emission Bus Zones to be introduced in Putney and Brixton in 2017

This briefing paper looks closely at the Euro 6/VI vehicle emissions standards, which tighten the limits on air pollutant emissions established in prior European standards, and require the best available technology for vehicle emissions control.

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.

Having pushed the auto makers to advance Bharat Stage (BS)-VI norms by four years, the government intends to relax fuel specifications for oil refineries, majority of which are in the public sector

The primary objective of this literature review is to provide a glimpse at technology changes for diesel and natural gas (NG) engines in the HDV space that are expected over the next 10 to 15 years as India transitions to world-class criteria pollutant emissions standards and improved efficiency becomes a larger focus as a result of fuel efficie

This report presents the manufacturing costs of emission control technology used to meet recent U.S. and European emission standards for heavy-duty diesel engines and vehicles. The costs assessed include both the in-cylinder technologies to control engine-out emissions and the after treatment technologies that act on the exhaust stream.
