WEBINAR Replay – With Nick Molden, Emissions Analytics’ Founder and CEO

This webinar seeks to demonstrate real-world emissions performance on the most recently certified passenger cars in Europe, and to examine what that reveals about the automakers approach to emissions reduction and compliance. Thank you all who joined the webinar with Nick Molden, Emissions Analytics’ Founder and CEO on 15th October 2018. If you missed the … Read more

Real Driving Emissions is a tough regulation, but also a risky one

Aggressive driving on average increases pollutant emissions by 35% in rural driving and by around five times on the motorway, according to testing of the latest passenger cars by Emissions Analytics on its EQUA Index programme. Even higher “hotspots” have also been identified, where emissions at high speed can peak at more than ten times … Read more

Discrepancies between best and worst diesel cars reaches record high

The first diesel vehicle that met the regulated Euro 6 limit for nitrogen oxides (NOx) on our real-world EQUA Index (www.equaindex.com) test using a Portable Emissions Measurement System (PEMS) was in May 2013. Of the vehicles we tested in that year, the cleanest 10% of diesels emitted 265 mg/km and the dirtiest 10% emitted 1777 … Read more

Rethinking Scrappage For Addressing Vehicle Emissions

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 … Read more

Cutting pollution and improving public health

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. The report made 22 policy recommendations, many of which related to monitoring and ameliorating pollutant emissions. Emissions Analytics is pleased to have … Read more

Electric vehicles now rated by EQUA Index – Tesla 3 result

Electric vehicles have no tailpipe emissions – obviously. They do have indirect emissions from upstream manufacturing, and in-use emissions from tyre and brake wear, but it is range and efficiency which are of direct practical importance to owners. As range anxiety diminishes with larger batteries, the relative efficiency of EVs will become more important in … Read more

Can driving styles prove the smarter route to better fuel economy and 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 … Read more

Very cleanest cars revealed: new A+ rating from the EQUA Index

Emissions Analytics’ EQUA Index (www.equaindex.com) has been revealing the cleanest and most efficient cars since it launched in 2016. Since then, technology and vehicle performance have improved to a point that a new class of even cleaner vehicles can now be revealed. On 17 October, the Mayor of London, in collaboration with Emissions Analytics, launched … Read more

AIR – a new global alliance promoting on-road vehicle emissions tests

AIR – Allow Independent Roadtesting -has been launched and is a new global alliance promoting the voluntary adoption of an independent on-road vehicle emissions test and rating system.

Euro 6 cars entering Clean Air Zones

Why cold starts could freeze air pollution improvements

The latest analysis of the EQUA Index data shows that the average daily distance driven in passenger cars is not sufficient for a vehicle’s pollution control system to warm up and become fully functional. The resultant high levels of cold start NOx emissions, from both gasoline and diesel engines, could provide an additional challenge for … Read more

Vans weigh in on the EQUA Index

Vans weigh in on the EQUA Index Light commercial vehicles (LCVs) travelled 48.5 billion miles last year according to the Department for Transport[1]. In its tests, Emissions Analytics has seen similar levels of variability from official fuel economy and emissions figures in vans as in cars. With van mileage growing by an average of 4.1% … Read more

The EQUA Mpg gap increases further in 2016

This year’s round up of EQUA fuel economy data shows a five percentage point increase in the gap between official and real-world mpg, reaching 29% in 2016. Official mpg figures averaged 60.7mpg in the year, the highest we have seen since we started recording in 2011. This is an increase of 9% on 2015’s figures, which stood at … Read more

Snapshot #9: Class matters when it comes to MPG

We looked at our data on over 750 EU cars tested, to see how much of an influence vehicle class was on variance between the NEDC-derived official MPG and our cycle and found: Petrol sports cars come closest to their official figures The MPG gap is worse for small cars, whatever the fuel Overall the gap is almost always bigger for diesel engines.
