The VW scandal and what does it mean for TTIP?

Unless you have buried your head in the sand over the last couple of days, you would have been hard pressed to miss the VW cheating scandal that has erupted in the United States. A tsunami of media stories have taken over the front pages of the FT, NYT, The Guardian, Le Figaro, Il Sole 24 Ore, to name a few.

Briefing: Environmental Goods Agreement

Launched in July 2014, the Environmental Goods Agreement (EGA) is being negotiated between the European Union – on behalf of its 28 member states – and 16 other members of the World Trade Organisation (WTO). The selection of goods for the EGA list was undertaken in secrecy and without a definition of an environmental good or selection criteria. T&E has identified around 120 items on the list of 650 goods for which we do not see any environmental justification for lowering tariffs. We argue that negotiations should open up and the assessment of what is an environmental good should be conducted by recognised experts in full transparency, on the basis of a widely accepted methodology.

Realistic real-world driving emissions tests: the last chance for diesel cars?

Harmful levels of air pollution are endemic in European cities, especially close to roads, causing 400,000 premature deaths annually and costing the EU a whopping €1 trillion a year. This paper focuses on the role played by diesel cars in the air pollution crisis and identifies obsolete tests and optimisation strategies by car manufacturers as the reasons they have failed to deliver real-world improvements. It explores the Commission’s proposed new real-world driving (RDE) test, which is to be implemented for new Euro 6 standard vehicles, and outlines a timetable to address important issues relating to air pollution from cars.

Non-Road Mobile Machinery: The good, the bad and the dirty

This briefing assesses the new regulation proposal for emissions from non-road mobile machinery (NRMM). It makes modest progress in covering a wider range of engines types and in tackling the issue of particulates emissions. However, T&E finds that the proposal is likely to create market distortion and favour specific fuel/technologies that cannot be justified. It also has no requirement on existing engines to adopt retrofit equipment to have an earlier impact on air quality, resulting in an unacceptably long wait in light of the persistent air quality problems around Europe.

Realistic real-world driving emissions tests: a last chance for diesel cars?

Air pollution emissions limits for cars, vans and trucks (Euro Standards) have been progressively tightened, on paper, over 25 years but have failed to deliver real-world improvements for several key pollutants, notably nitrogen dioxide. This is because obsolete tests and “cycle beating” techniques have been used by carmakers leading to levels of emissions from some cars many times higher on the road than in laboratory tests. In October 2014, the Commission will be discussing progress and next steps with EU member states. This paper outlines key issues for member states to ensure that the new real-world (PEMS) tests are robust and representative of real-world driving in order for emissions to decline on the road. 

Draft proposal on pollutant emissions from NRMM

The aim of the European legislation on pollutant emissions from Non-Road Mobile Machinery (NRMM) is to protect human health and the environment. This can only be achieved by strict emissions limits aligned with Euro VI emissions limits for trucks and buses. The Commission draft proposal for NRMM legislation must be reinforced to achieve its objectives and be coherent with the emissions legislation for road sources.

In this briefing T&E explains how, as it stands, the draft proposal on NRMM emissions is incoherent and worryingly weak, and will fail to adequately address the burden on health caused by the diesel exhaust from these machines.

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.
