Tackling real world emissions from cars

Sketch of a book (default image for publications

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.

Air pollution forces Paris number plate ban

A peak in air pollution brought a drastic change to transport habits in Paris for one day, following a combination of unseasonably hot weather and diesel cars fumes. No strangers to air pollution regularly exceeding EU limits, the authorities in the French capital banned all cars with even-numbered licence plates from entering the city on 17 March due to exceptionally high levels. The idea was to ban odd-numbered plates the next day, but that proved unnecessary as a 25% reduction in traffic and cooler weather brought pollution levels down.

Car emissions deal for 2020 will reduce CO2, create jobs and lower fuel bills

Transport & Environment welcomes the result of the European Parliament vote on new car CO2 emissions in 2020, but regrets the unnecessary weakening of the June agreement. The agreement confirmed today by the European Parliament means that the 95 gram CO2/km target will now be met one year later than planned, in 2021. 

30% car-CO2 cut becomes law after MEPs vote

A deal to salvage something of the EU’s post-2015 strategy to reduce carbon dioxide emissions from new cars has been agreed by MEPs. The European Parliament voted this week to approve the original 95 grams per kilometre limit, but by 2021, not 2020 as planned. T&E said the weakening of the Commission’s original proposals was ‘unnecessary’ and would create additional CO2 emissions, but it was still an acceptable deal overall.

Free BMW and Audi cars a conflict of interest?

A leading Green MEP has questioned whether sponsorship of the EU presidency by Audi and BMW could represent a conflict of interest. The German luxury carmakers provided free cars to EU member states that were responsible for leading policy negotiations over new carbon emissions targets.

Carmakers failing citizens on filters

The health of millions of European citizens is being put at risk by carmakers’ failure to put cheap particle filters on new direct-injection petrol engines. The new engines are more fuel-efficient and emit much less carbon dioxide than traditional petrol engines, but T&E-commissioned testing shows they typically emit around 1,000 times more harmful particles, which cause cancer and pose other threats to human health.

When industry makes a racket, citizens end up paying the bill

It is a sign of the times that even the British Lords in the House of Lords have accepted that noise is a major problem. After recent noisy protests outside their building, some Lords were forced to flee their chambers, while others reported physical illness. For them, the culprit may be noisy protests, but for many people (44% of EU citizens to be more precise), this noise disturbance comes from vehicles.
