Diesel, natural gas, and electric heavy-duty vehicles can be designed and manufactured with the capability of complying with the ultra-low NOx limits envisioned in the next set of California and federal HDV regulations. But that is not to say that the outcomes for each are equivalent.

This document is the annual EU emission inventory report under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP Convention) (UNECE, 1979).

This briefing presents progress made by the EU and its Member States towards meeting the 2010 emission ceilings that were applicable until the end of 2019 under Directive 2016/2284/EU — the National Emission reduction Commitments (NEC) Directive — on the reduction of national emissions of certain atmospheric pollutants.

The nationwide Lockdown, in effect since the midnight of 24 March in view of COVID-19 pandemic, has resulted in significant improvement in air quality in the country, as revealed by data analysis and comparison of data for time before enforcement of restrictions.

As Indian metro cities continue to battle alarming pollution levels, Greenpeace’s analysis of NO2 satellite data re-asserts that transport and industrial clusters are giving rise to the country’s worst Nitrogen Oxide (NOx) hotspots.

Remote sensing is one technique used to measure real-world NOx emissions in Europe. Remote sensing measurements conducted by the Canton of Zurich are unique in terms of how consistently they have been collected since 2000 and the steep road grade at the main remote sensing monitoring site.

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.
