Traduction de «réduction des oxydes » (Français → Anglais) :

The University of Waterloo clearly stated that there was such variability in the test results that the amount of improvement or reduction in NOx was well within the variability of the data.

If we have long-term capital investments and a lot of upfront costs running 8% to 12% returns on investment, no matter how much carbon dioxide they reduce and everything else, they have to look at the bottom line.

1. Member States shall, as a minimum, limit their annual anthropogenic emissions of sulphur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds other than methane (NMVOC), ammonia (NH3), particulate matter (PM2,5) and methane (CH4) in accordance with the national emission reduction commitments applicable from 2020 and 2030, as laid down in Annex II.

(vi)the chemical or electrolytic reduction of metalloid oxides or non-metal oxides such as silicon oxides and phosphates.

Setting such a step for reducing nitrogen oxide emissions at an early stage will provide long-term, Europe-wide planning security for vehicle manufacturers.
