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.

Transport to become largest source of CO2 emissions if politicians don’t act decisively, UN experts warn

The latest United Nations Intergovernmental Panel on Climate Change (IPCC) report published today alerts global leaders to the growing threat of uncontrolled transport emissions. The UN's climate panel says that transport is set to become the world’s biggest source of CO2 emissions unless lawmakers take strong action now. The report states: “Without aggressive and sustained policies (to cut CO2 from cars and trucks), transport emissions could increase at a faster rate than emissions from any other sector.”

IMO succumbs to pressure to delay ship NOx regulations

The International Maritime Organisation (IMO) today abandoned the fixed start date for new NOx emissions control areas (NECAs), which require an 80% cut in NOx from new ships sailing in specially designated zones. Instead, the IMO will replace the 2016 application date with flexible provisions for any NECAs established after that date. Transport & Environment (T&E) deplores this rushed-through decision, as it will negatively impact on the environment and the health of Europeans.

Growing evidence of health threats from tar sands exploitation

As the delay on the proposal to implement the Fuel Quality Directive reaches 1,186 days, there is growing evidence that tar sands mining and drilling operations, pipelines, and refineries are exposing local communities to serious health risks and problems.

Crucial decision on ‘technically feasible’ ships NOx reduction

Curtailing nitrogen oxide (NOx) emissions from ships is ‘technically feasible’, according to a new study published ahead of this week’s Marine Environment Protection Committee (MEPC) meeting that will decide on a proposal to postpone the 2016 introduction of NOx emission control areas at sea.

Fight to defend environment and consumer protection slows EU-US trade talks

The EU trade commissioner Karel de Gucht has ordered a public consultation on a legal clause in the emerging EU-US trade agreement that campaigners say could undermine environmental and consumer protection. The legal provision, known as ‘investor-state dispute settlement’, would give companies the right to take legal action against governments if they feel their investment potential or profits are being hindered by regulatory or policy changes at national level. What’s more, such disputes would be judged by special panels made up of people acceptable to business interests, and bypass national laws.

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.
