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.

EU-wide car labelling

A new study has recommended Europe should have a single fuel economy and carbon dioxide labelling system for cars. The study by the British consultancy AEA looked at the labelling systems in operation in eight member states, and found some compare a car with the whole car market while others show only how it compares with others of the same type. It says comparisons against the whole of the available car fleet are likely to be more useful in the absence of further research. Another report in 2010 also recommended a harmonised approach to labelling.
