For this study, a C-segment passenger vehicle, equipped with a gasoline direct injection engine and compliant with the Euro 6c standard, was tested on the chassis dynamometer over the regulatory NEDC and WLTC cycles, and over two RDE-like cycles. The tests were performed at different ambient conditions and with both cold and warm engines.

Globally, the estimates suggest that there are 170 new cases of traffic pollution-related asthma per 100,000 children every year, and 13% of childhood asthma cases diagnosed each year are linked to traffic pollution. The country with the highest proportion of traffic pollution-attributable childhood asthma incidence was South Korea (31%), the UK ranked 24th out of 194 countries, the US 25th, China 19th, and India 58th.

On Monday, London Mayor Sadiq Khan unveiled the world’s first 24-hour Ultra Low Emission Zone boasting the world’s toughest vehicle emissions standards in an effort to help reduce toxic air polluti

As air quality improves, the invisible chemistry happening in the air around us is changing.

Coarse particulate matter with aerodynamic diameter between 2.5 and 10μm (PM2.5–10) air pollution is a severe environmental problem in developing countries, but its challenges to public health were rarely evaluated. The researchers aimed to investigate the associations between day-to-day changes in PM2.5–10 and cause-specific mort

The Supreme Court on Monday said that the National Green Tribunal can examine automobile manufacturers other than Volkswagen also for flouting emission norms if it deemed fit to widen the judicial

The National Green Tribunal Thursday slammed Volkswagen for not depositing Rs 100 crore, imposed on the German auto major for damaging the environment through use of 'cheat device' in its diesel ca

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.

Limnological theory posits that phosphorus (P) limits primary production in freshwater lakes, in part because fixation of atmospheric nitrogen (N2) can compensate for limitations in nitrogen (N) supply to phytoplankton. However, quantitative estimates of the degree to which N2 fixation satisfies planktonic N demand are rare.
