How clean are Europe’s cars 2014 – Part 1

The EU set legally-binding targets for new cars to emit on average 130 grams of CO₂ per kilometre (g/km) by 2015 and 95g/km by 2021. This briefing, the first part of T&E’s ‘How clean are Europe’s cars 2014’, analyses the official data from the European Environment Agency on progress towards these targets made by carmakers in 2013. The second and third part of the report will cover electric vehicles and supercredits as well as the gap between carmakers claimed fuel economy and the real world figure.

Tackling real world emissions from cars

Light duty vehicles (LDVs) emit more pollutants on the road than in laboratory conditions. In order to solve this problem the Commission decided to introduce complementary type-approval procedures to measure gaseous and particulate emissions during real driving to make sure that they are similar to legal emission limits. To achieve this, the Real-Driving Emissions-Light Duty Vehicles (RDE-LDV) working group was created in 2011. Work in this group is currently focused on RDE tests during initial type approval.

This paper has been prepared by T&E to aid the work of this group. The paper considers the main topics of discussion: data analysis methods, boundary conditions, conformity factor, equipment (portable emissions measurement system – PEMS) and scope.

Particle emissions from petrol cars

Vehicle tests show that without the use of gasoline particulate filters (GPF) the number of particles emitted from gasoline direct injection (GDI) engines is likely to exceed future European emissions limits, known as Euro 6 standards. Nowadays, particle emissions from these new petrol engines are higher than equivalent diesel vehicles. The cost of a filter to eliminate particle emissions is low (around €40), with no fuel economy penalty. Despite this, carmakers are delaying fitting filters on GDI cars and instead rely on manipulating tests. Their reluctance is worsening urban air pollution and reducing the health benefits of the new limits.

Tackling emissions from diesel machines

European air pollution rules for diesel machines such as bulldozers, excavators and barges are much more lax than those for cars and lorries. As well as this, some engine types and older machines are excluded from air pollution law. This is a problem because, according to the World Health Organisation (WHO), diesel exhaust is carcinogenic. Ambitious, comprehensive and consistent rules are needed to limit air pollution emissions from non-road mobile machinery (NRMM - diesel machines). These are required to address the growing urban air pollution that Europe faces. T&E believes that future EU legislation on diesel machines must be in line with emissions limits for equivalent road vehicles.

Vehicle noise: final trilogue negotiations

Traffic noise is the second-biggest environmental factor affecting Europeans’ health after air pollution. Almost half of EU citizens are regularly exposed to road traffic noise over the level that the World Health Organisation considers to pose a serious risk to health. Noise pollution has been linked to 50,000 fatal heart attacks every year in Europe. This briefing outlines the European Commission, Parliament and Council positions on a proposal for new vehicle noise standards ahead of a third round of trilogue negotiations on 5 November, 2013. It also outlines T&E's analysis of the main issues as well as its recommendations for a compromise that avoids legal and technical loopholes.

Open letter to the Lithuanian Presidency of the EU calling on the deal on CO2 emissions from cars to be put to a vote

In this open letter to the Lithuanian Presidency of the Council of the EU, Transport & Environment and Greenpeace call on the Presidency to fulfil its role as neutral and unbiased chair, follow the wish of the vast majority of member states and the two other EU institutions, and put the agreed deal to reduce CO2 emissions from new cars to a vote.

How clean are Europe's cars 2013

This report is the eighth T&E has published on the annual progress Europe’s major car manufacturers have made in reducing CO2 emissions and fuel consumption of new cars. As we did in previous reports, we also assess progress per EU Member State and review how official CO2 figures are translating into the ‘real world’.
 

Manipulation of fuel economy test results by carmakers: new evidence and solutions

Sketch of a book (default image for publications

A growing body of evidence shows the current test used to measure car fuel efficiency is outdated, unrepresentative of real-world driving and lax enough to allow carmakers to systematically manipulate official test results at the expense of consumers’ trust. European institutions are presently finalising a regulation to lower CO2 emissions from cars and vans in 2020. This has stimulated intense debate when and how a new official test should be introduced. This briefing informs this debate in the light of new evidence from the International Council on Clean Transportation (ICCT) that for the first time compares progress in official and real-world vehicle fuel efficiency on a brand-by-brand basis.

Mind the Gap! Why official car fuel economy figures don’t match up to reality

This report provides new evidence and understanding on why there is a growing gap between the official fuel consumption and CO2 emissions of new passenger cars and vans, and that which is achieved by the same vehicles on the road. It demonstrates that the current (NEDC) test is outdated and unrepresentative of real-world driving and current vehicles, and that lax testing procedures are allowing car-makers to manipulate the official tests to produce unrealistically low results. The report also shows that the current supervision of testing and checks on production vehicles (to ensure these are equivalent to tested vehicles) are inconsistent and inadequate, with manufacturers paying the organisations undertaking and certifying the tests. The conclusion is that the current system for measuring car and van fuel economy and CO2 emissions is not fit for purpose and is in need to urgent updating.
