The webinar covering the latest results on the effect of renewable fuels on combustion emissions, which has been conducted together with the University of Oxford. It will look at the chemical composition of renewable fuels, consider the impact that has on tailpipe emissions, and see how well Euro 7 may capture these effects.
That’s 1,000,000,000,000,000,000,000,000 exhaust emissions particles that are due to be emitted in the United States that don’t need to be. How? A large majority of European and Chinese cars are now sold with tailpipe particle filters, known as gasoline particulate filters (GPFs) or diesel particulate filters (DPFs) in the industry, but this is not the case in the US.
Scrappage schemes are controversial. In a 2011 academic paper* reviewing 26 studies assessing the outcomes of 18 scrappage schemes implemented around the world in 2008-11, the authors concluded that the emission effects of the schemes were ‘modest and occur within the short term.’ They also concluded that the cost-effectiveness of such schemes ‘is often quite poor.’
Pollution is a major contributor to chronic human sickness, not just environmental damage, according to the 2017 annual report of England’s Chief Medical Officer, Professor Dame Sally Davies, released on 2 March 2018: https://www.gov.uk/government/publications/chief-medical-officer-annual-report-2017-health-impacts-of-all-pollution-what-do-we-know. The report made 22 policy recommendations, many of which related to monitoring and ameliorating pollutant emissions.
The relevance of official fuel economy figures is still a perennial topic across the automotive industry, and one of the hardest to answer directly takes into account the human factor. Some claim that the official figures are in fact perfectly valid, if only the average driver wasn’t so lead-footed. But is there any truth in this train of thought?
Diesel has had something of a rough time of it over the past 18 months. It started with the Volkswagen ‘Dieselgate’ scandal that broke in September 2015, while more recently there have been concerns over nitrogen oxide (NOx) emissions and air quality in general, especially in city centres.
According to Nick Molden, CEO and founder of Emissions Analytics – a company that tests car emissions in the real world – some meet and can even beat the limits prescribed by the Euro6 emissions regulations, while others, according to Emissions Analytics’ data, emit 20 times the NOx that they should.
