Highlight Explaining vehicle emissions – why do laboratory and road measurements differ?
The road transport sector is a major contributor to Europe’s emissions of greenhouse gases and air pollution. For certain pollutants, vehicles can emit substantially higher emissions on the road than official emissions tested in laboratories. A report released today by the European Environment Agency (EEA) provides a non-technical guide that describes the reasons for these often significant discrepancies.

Publication Explaining road transport emissions - A non-technical guide
Road transport is an important source of both greenhouse gases and air pollutants. Despite improvements in vehicle efficiencies over past decades, today the sector is responsible for almost one fifth of Europe's greenhouse gas emissions. Emissions from vehicles also lead to high concentrations of air pollutants above EU standards in many of Europe's cities. This report provides a summary of the current knowledge on vehicle emissions in Europe. It also explains how emissions are monitored and the common technologies used to limit them.

Infographic Troff document Flexibilities in the NEDC test approval procedure
Flexibilities exploited by manufacturers during the NEDC test cycle can be broadlygrouped into two categories: those relevant to the initial coast-down test and thoserelevant to the type approval test itself.

Infographic Air pollution: from emissions to exposure
Poor air quality is a serious health and environmental problem. Certain harmful air pollutants are emitted directly from vehicles, such as ‘primary’ particulate matter (PM) and nitrogen oxides (NOX). Others, such as ozone and ‘secondary’ PM, form in the atmosphere after emissions of precursor pollutants, including NOX and volatile organic compounds. Different sources of pollution, including transport and non-transport sources, emit different types and ratios of pollutants.

External Data Reference Copert 4
The popular, straightforward and simple to use emissions calculator. COPERT 4 is a software tool used world-wide to calculate air pollutant and greenhouse gas emissions from road transport. The development of COPERT is coordinated by the  European Environment Agency (EEA) , in the framework of the activities of the  European Topic Centre for Air Pollution and Climate Change Mitigation . The European Commission's  Joint Research Centre  manages the scientific development of the model. COPERT has been developed for official road transport emission inventory preparation in EEA  member countries . However, it is applicable to all relevant research, scientific and academic applications.

External Data Reference Mind the Gap 2015: Closing the chasm between test and real-world car CO2 emissions
Report of the European Federation for Transport and Environment: The system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. This report analyses the gap between test results and real-world performance and finds that it has become a chasm, increasing from 8% in 2001 to 31% in 2012 and 40% in 2014. Without action this gap will grow to nearly 50% by 2020.

Data Monitoring of CO2 emissions from passenger cars – Regulation 443/2009
The Regulation (EC) No 443/2009 requires Member States to record information for each new passenger car registered in its territory. Every year, each Member State shall submit to the Commission all the information related to their new registrations. In particular, the following details are required for each new passenger car registered: manufacturer name, type approval number, type, variant, version, make and commercial name, specific emissions of CO2, mass of the vehicle, wheel base, track width, engine capacity, fuel type and fuel mode. Additional information, such as engine power, were also submitted. Data for EU-28 are reported in the main database.

Data Monitoring of CO2 emissions from vans – Regulation 510/2011
The Regulation (EC) No 510/2011 requires Member States to record information for each new van registered in its territory. Every year, each Member State shall submit to the Commission all the information related to their new registrations. In particular, the following details are required for each new van registered: manufacturer name, type approval number, type, variant, version, make and commercial name, specific emissions of CO2, mass of the vehicle, wheel base, track width, fuel type and fuel mode. Additional information, such as engine power and engine capacity were also submitted.
