Emissions charge

摘要

Whatever happens with Euro 7 emissions legislation, the industry may well have cause for concern over the EC's and local legislators' measurement and penalty choices. That observation applies not only to NOx -widely expect to halve against Euro 6 (meaning 23mg/kWhr on the world harmonised test cycle). It also pertains to NO_2, which will probably get its own limits, forecast at around 110mg/kWhr. Furthermore, it applies to soot particle size for PN (particle number) regulation -predicted to move from the current 23 nanometre minimum diameter down to 10 nanometres. Experts agree that is only just measurable with current technology. However, there is also the EC's primary focus, aimed at forcing down CO_2 emissions. And, as reported in our March 2016 issue (page 10), if Europe follows the US, we can expect to see a 24% reduction in CO_2 emissions for HGVs, with 4% coming from engine upgrades -all of which must be measured and presented to fleet operators in terms relating to fuel efficiency.
