Car fuel economy and CO2 claims are (one-third) hot air!


Wow, we do get to read some fascinating reports for this blog (!).  The excitingly entitled report "Supporting Analysis regarding Test Procedure Flexibilities and Technology Deployment for Review of the Light Duty Vehicle CO2 Regulations (Service request #6 for Framework Contract on Vehicle Emissions) was published by the European Commission in December 2012.  

The research by the Dutch consultancy TNO looked at ‘manipulations/flexibilities’ in the "type" approval testing for vehicles in the European Union. 

The report states that up to two thirds of officially recorded emissions "can be credited to improved technologies". However, at least one third of the vehicle emissions (9g/km) are "likely to be the result of car makers manipulating the test procedures" and that the "estimate of the potential impact of test procedure flexibilities and their level of utilisation in the 2002-10 period appears to explain the remaining gap."

For many years, there have been concerns about the recorded discrepancies between the officially certified emissions of cars and what they actually emit when out on the road. Previously, these concerns focused on the appropriateness of "test cycles". But the growing gap between real-world driving and manufacturers test result claims led to the recent research on how test results can be manipulated by car manufactureres using "flexibilities" in their testing procedures.  

The TNO report supports an earlier German study (1) showed emissions savings recorded in Germany were only half the amount suggested by official figures.  This research, by the International Council on Clean Transportation compared official test results with a database of real-world fuel consumption in Germany using data from the website www.spritmonitor.de

ICCT compared over 28,000 records of real-world emissions with the official CO2 figures for the same vehicles. The report concluded that between 2001-2010, CO2 emissions in Germany fell 15% according to official figures, but that drivers reported only a 7% improvement. As a result, the fall in CO2 emissions from the average vehicle between 2006 and 2010 was officially 12% (173 g/km down to 152g) but in reality only reduced by 6% (190g down to 179g).

With Britain and Manchester failing to meet European Union air pollution targets - and likely to be on the receiving end of some large fines - we need car manufacturers to come clean about the real levels of CO2 and other pollution emissions from the vehicles that are manufactured and driven within the UK and the European Union.

Why not ask your MEP to look into the issue? You can find out who your MEP is and how to contact them via those lovely people at the Write to Them website.

Slow down (traffic) to speed up (cycling)

This Wednesday sees the first session of the All Party Parliamentary Cycling Group's (APPCG) "Get Britain Cycling" inquiry.  As the Guardian correspondent, Peter Walker, highlights there has been a lot of chatter about how Britain has become a nation of cyclists following Bradley Wiggins winning the Tour de France and the great cycling performances by Team GB in the Olympics.

Except, as the article illustratess, this is not the case. "Exclude racing or tourism and Britons are near the bottom of just about every European cycling ranking. Just 2.2% of people use a bike as their main means of transport, lower than all but a handful of EU nations such as Bulgaria, Malta and Cyprus.Other statistics are equally damning. About 2% of British children ride to school, compared with 40% in Denmark and 20% in Sweden." 

One of the key reasons given by people who would like to cycle but who currently do not is that they do not feel safe cycling because of the speed of traffic on the roads. Research from Portland (USA) identified that some 60% of adults are in this "interested, but concerned" category. Have not seen any similar research from the UK, but from personal experience would consider that a similar proportion of people would fall into this category.

Manchester City Council agreed  on 1st February 2012 that Council officers would produce a report for the Council Executive on the "feasibility of installing a city-wide 20mph limit on residential roads, excluding major routes as appropriate." 

In March 2012, this report was submitted to the Communities and Neighbourhoods Overview and Scrutiny Committee. The report recommended that Manchester Council should:

"investigate potential funding mechanisms to implement 20mph speed limits on all C and U classed roads in Manchester with a view to installing the proposed speed limits, subject to public consultation"  and  would "commission further analysis of speed and accident data and preliminary consultation to determine which roads would be most appropriate for 20mph speed limits or 20mph zones. Data analysis and site surveys would inform which areas should be subject to the preliminary public consultation."

Not a lot has been heard publicly on this issue since then - although Manchester City Council did announce on 18th October 2012 that:


"Buses are to drive at 20 miles per hour within the city centre under a new voluntary code of conduct for operators. All bus companies running services into the city centre are expected to sign up to the CityPLAN agreement which means drivers will stick to the limit within the inner ring road - and drive at 10mph or less in busy locations such as Parker Street, Oldham Street and Shudehill Interchange. The move comes as Manchester City Council looks into ways of creating more 20 mile per hour zones across the city, and is expected to improve safety, especially for pedestrians and cyclists." 

Which is a step forward for the City Centre area but there is a need to reduce traffic speeds in all residential areas in Greater Manchester to help encourage people to walk and cycle more.



Many local councils have argued that there are too many 'enforcement' and 'legal' barriers to introducing 20mph default speed limits and therefore it is too difficult or costly. However, on 18th January 2013, Stephen Hammond, Transport Minister told Parliament in a written statement that the new Department for Transport (DfT) guidance “incorporates recent changes that create more flexibility for [local] authorities to implement 20mph limits and zones.”

This new guidance encourages 20mph  limits in a number of ways :-
  • It identifies as priority for action that “Traffic authorities are asked to keep their speed limits under review with changing circumstances, and to consider the introduction of more 20 mph limits and zones, over time, in urban areas and built-up village streets that are primarily residential, to ensure greater safety for pedestrians and cyclists, using the criteria in Section 6.” (para 12)
  • It recognises the importance of the “composition of road users (including existing and potential levels of vulnerable road users)” as a key factor that needs to be taken into account. (para 30).
  • It recognises that “Fear of traffic can affect peoples’ quality of life and the needs of vulnerable road users must be fully taken into account in order to further encourage these modes of travel and improve their safety. Speed management strategies should seek to protect local community life.” (para 32)
The guidance also highlights how:

"There is clear evidence of the effect of reducing traffic speeds on the reduction of collisions and casualties, as collision frequency is lower at lower speeds; and where collisions do occur, there is a lower risk of fatal injury at lower speeds. Research shows that on urban roads with low average traffic speeds any 1 mph reduction in average speed can reduce the collision frequency by around 6% (Taylor, Lynam and Baruya, 2000). There is also clear evidence confirming the greater chance of survival of pedestrians in collisions at lower speeds."


Traffic speed limits in residential areas affect everyone, not only as car drivers and passengers, but also as pedestrians, cyclists and residents. They also impact of people's quality of life, the environment and the local economy.

Lets hope that the All Party Parliamentary Cycling Group inquiry can help encourage national government and local authorities to take bolder steps on reducing traffic speeds in residential areas.

Manchester City Council has some great opportunities to start implementing area-wide 20mph speed limits with the upcoming Oxford Road corridor consultation and the Brunswick redevelopment plans.


It would also be great to see other Greater Manchester local authorities start implementing this too.  If you know of any good local examples please leave a comment.

Snow clearance or should that be No clearance?

Cycled to the Trafford Centre today and came across a clear example of the lack of priority given to ensuring that cycle lanes are useable throughout the year.

The road space has been gritted and was clear of snow and ice but the cycle lane element of the shared use area has not been cleared. 

In November 2010, the local newspaper reported Alan Mitchell (Executive councillor for Highways) as saying: "Having these quad bikes available for use gives us much more flexibility than we had last year in terms of gritting priority pedestrian routes."

Perhaps Trafford Council could send them down to the Trafford Centre......

If the pavements or cycle lanes near you have not been cleared then Councillor Alan Mitchell can be contacted via this email alan.mitchell@trafford.gov.uk

Norwich 58 ... Manchester er?

On a recent visit to Norwich by train I noticed quite a large amount of bike parking at the train station. Well located and mostly covered there are a total of 58 Sheffield stands, which at 2 bikes to one stand provides secure parking for 116 bicycles.

Cycle parking at Norwich station (1)
According to Norwich City Council, the population of the Norwich Travel to Work Area (TTWA) is 376,500 whilst 132,200 people live in the Norwich City Council area.

In comparison, the Office for National Statistics has estimated that the TTWA population for Manchester is 1,204,000 and the latest Census puts Manchester's population at 503,100 people.   

Basically, Manchester is nearly 4 times the size of Norwich in terms of both the Travel to Work Area and resident populations.

So with plans to increase the amount of people cycling in Manchester you would think that Manchester's key train station - Manchester Piccadilly would  have the same amount, or preferably more cycle parking provision that Norwich. Well you might, but unfortunately you would be wrong !


Whilst, Manchester Piccadilly has recently seen some additional bike parking installed (basically as a planning requirement for the new car park) it still only has the grand total of 43 Sheffield stands (most of these are not under cover) which provides parking provision for 86 bicycles.... 

New cycle parking at Piccadilly station 1
Allowing for the difference in population and Travel to Work area ratios, to match Norwich, Manchester Piccadilly should have 232 Sheffield stands.  

Achieving such an increase in cycle parking at Manchester Piccadilly would be most welcome but so far it would appear that Network Rail have been unwilling to provide high-class cycle parking facilities in either the quantity or quality warranted by a major train station serving the UK's second largest conurbation.

Contrast this to the recently announced plans to build the "biggest cycle parking facility in the UK" at Cambridge station. The plan is to install cycle parking to cater for 3000 bicycles.

If you think that Manchester Piccadilly should increase the provision for cycle parking why not send a (polite) email to Network Rail and/or your local councillor (see the Write to Them website to find details of your local councillors).
