The modelling used for the air quality plan was based on the best available data and uses the latest COPERT (Computer Programme to Calculate Emissions from Road Transport) (4v11) factors to calculate emissions from diesel cars.<\/p>
These COPERT factors reflect that there is a difference between laboratory testing of vehicle emissions and real world emissions. They assume Euro 6 diesel cars are, on average, emitting 2.8 times the level of emissions allowed for the Euro 6 standard.<\/p>
In May, the Government will present the results of its vehicle testing programme (www.gov.uk/government/publications/vehicle-emissions-testing-programme-conclusions) to European Research for Mobile Emission Sources (ERMES), the body responsible for collating vehicle emission data, to inform its updated emissions factors later this year. This will ensure that EU-wide emission factors continue to focus on the latest data updated on the basis of real world testing.<\/p>"} , "answeringMember" : {"_about" : "http://data.parliament.uk/members/4137", "label" : {"_value" : "Biography information for Rory Stewart"} } , "answeringMemberConstituency" : {"_value" : "Penrith and The Border"} , "answeringMemberPrinted" : {"_value" : "Rory Stewart"} , "dateOfAnswer" : {"_value" : "2016-05-04", "_datatype" : "dateTime"} , "isMinisterialCorrection" : {"_value" : "false", "_datatype" : "boolean"} , "questionFirstAnswered" : [{"_value" : "2016-05-04T16:54:48.243Z", "_datatype" : "dateTime"} ]} , "answeringDeptId" : {"_value" : "13"} , "answeringDeptShortName" : {"_value" : "Environment, Food and Rural Affairs"} , "answeringDeptSortName" : {"_value" : "Environment, Food and Rural Affairs"} , "date" : {"_value" : "2016-04-28", "_datatype" : "dateTime"} , "hansardHeading" : {"_value" : "Motor Vehicles: Exhaust Emissions"} , "houseId" : {"_value" : "1"} , "legislature" : [{"_about" : "http://data.parliament.uk/terms/25259", "prefLabel" : {"_value" : "House of Commons"} } ], "questionText" : "To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate of real world diesel emissions for Euro 6 vehicles, relative to the laboratory test limit, was used in the evidential basis supporting her Department's conclusion that eight air quality zones would not comply with Nitrogen Dioxide limits by 2020 if no action is taken.", "registeredInterest" : {"_value" : "false", "_datatype" : "boolean"} , "tablingMember" : {"_about" : "http://data.parliament.uk/members/1491", "label" : {"_value" : "Biography information for Kerry McCarthy"} } , "tablingMemberConstituency" : {"_value" : "Bristol East"} , "tablingMemberPrinted" : [{"_value" : "Kerry McCarthy"} ], "uin" : "36062"} , {"_about" : "http://data.parliament.uk/resources/515827", "AnsweringBody" : [{"_value" : "Department for Environment, Food and Rural Affairs"} ], "answer" : {"_about" : "http://data.parliament.uk/resources/515827/answer", "answerText" : {"_value" : "
Tackling air quality is a priority for this Government and we are committed to meeting air quality limits for nitrogen dioxide in the shortest possible time. Defra and the Department for Transport work closely together at all levels to embed air quality considerations in the development of transport policy and delivery, including in relation to vehicle emissions. The inter-Ministerial group on Clean Growth meets as and when required and its members include Ministers and officials from the relevant departments, including Defra and the Department for Transport.<\/p>

The Government\u2019s comprehensive National Air Quality Plan (www.gov.uk/government/publications/air-quality-in-the-uk-plan-to-reduce-nitrogen-dioxide-emissions), published in December last year, is based on the best available evidence and uses the latest COPERT (Computer Programme to Calculate Emissions from Road Transport) (4v11) factors to calculate emissions from diesel cars.<\/p>

In May, the Government will present the results of its vehicle testing programme (www.gov.uk/government/publications/vehicle-emissions-testing-programme-conclusions) to European Research for Mobile Emission Sources (ERMES), the body responsible for collating vehicle emission data, to inform its updated emissions factors later this year. This will ensure that EU-wide emission factors more accurately reflect the difference between real world driving and laboratory test conditions.<\/p>

As part of the exhaust emissions approval process vehicle manufacturers are obliged to undertake in-use emissions testing. They are required to submit a report of their results at regular intervals or when requested to do so by the approval authority. In accordance with EU regulation 715/2007, the authority will review the information and accept or reject the report. The UK type approval authority is the Vehicle Certification Agency (VCA) and they ensure manufacturers follow this process where they are the issuing approval authority.<\/p>"} , "answeringMember" : {"_about" : "http://data.parliament.uk/members/4210", "label" : {"_value" : "Biography information for Lord Ahmad of Wimbledon"} } , "answeringMemberPrinted" : {"_value" : "Lord Ahmad of Wimbledon"} , "dateOfAnswer" : {"_value" : "2016-05-04", "_datatype" : "dateTime"} , "isMinisterialCorrection" : {"_value" : "false", "_datatype" : "boolean"} , "questionFirstAnswered" : [{"_value" : "2016-05-04T11:11:07.557Z", "_datatype" : "dateTime"} ]} , "answeringDeptId" : {"_value" : "27"} , "answeringDeptShortName" : {"_value" : "Transport"} , "answeringDeptSortName" : {"_value" : "Transport"} , "date" : {"_value" : "2016-04-26", "_datatype" : "dateTime"} , "hansardHeading" : {"_value" : "Motor Vehicles: Exhaust Emissions"} , "houseId" : {"_value" : "2"} , "legislature" : [{"_about" : "http://data.parliament.uk/terms/25277", "prefLabel" : {"_value" : "House of Lords"} } ], "questionText" : "To ask Her Majesty\u2019s Government what assessment they have made of emission tests undertaken by car manufacturers in the UK.", "registeredInterest" : {"_value" : "false", "_datatype" : "boolean"} , "tablingMember" : {"_about" : "http://data.parliament.uk/members/4153", "label" : {"_value" : "Biography information for Lord Kennedy of Southwark"} } , "tablingMemberPrinted" : [{"_value" : "Lord Kennedy of Southwark"} ], "uin" : "HL8009"} , {"_about" : "http://data.parliament.uk/resources/514532", "AnsweringBody" : [{"_value" : "Department for Transport"} ], "answer" : {"_about" : "http://data.parliament.uk/resources/514532/answer", "answerText" : {"_value" : "
The Vehicle Certification Agency\u2019s (VCA) emissions testing is conducted to the requirements set out in the relevant type approval legislation. The Government has been pressing for action at an EU-level to improve emissions tests and we have already secured a tough new Real Driving Emissions test. From next year, vehicles will have to meet emissions limits in real driving conditions across a wide range of typical operating conditions.<\/p>

The Secretary of State has met with the Chief Executive of Volkswagen UK to press that the technical fixes are completed as quickly as possible for UK consumers. The VCA is working closely with the VW group and other approval authorities to evaluate the proposed technical solutions. They are carrying out tests to ensure that after the fix is applied the vehicles meet all the legal requirements including emissions, and that other vehicle characteristics are unchanged, including fuel consumption and engine noise.<\/p>"} , "answeringMember" : {"_about" : "http://data.parliament.uk/members/3996", "label" : {"_value" : "Biography information for Andrew Jones"} } , "answeringMemberConstituency" : {"_value" : "Harrogate and Knaresborough"} , "answeringMemberPrinted" : {"_value" : "Andrew Jones"} , "dateOfAnswer" : {"_value" : "2016-04-25", "_datatype" : "dateTime"} , "isMinisterialCorrection" : {"_value" : "false", "_datatype" : "boolean"} , "questionFirstAnswered" : [{"_value" : "2016-04-25T13:29:58.21Z", "_datatype" : "dateTime"} ]} , "answeringDeptId" : {"_value" : "27"} , "answeringDeptShortName" : {"_value" : "Transport"} , "answeringDeptSortName" : {"_value" : "Transport"} , "date" : {"_value" : "2016-04-20", "_datatype" : "dateTime"} , "hansardHeading" : {"_value" : "Motor Vehicles: Exhaust Emissions"} , "houseId" : {"_value" : "1"} , "legislature" : [{"_about" : "http://data.parliament.uk/terms/25259", "prefLabel" : {"_value" : "House of Commons"} } ], "questionText" : "To ask the Secretary of State for Transport, what recent changes there have been to Vehicle Certification Agency emissions testing; and what recent discussions he has had with Volkswagen on progress on fixing all defeat devices.", "registeredInterest" : {"_value" : "false", "_datatype" : "boolean"} , "tablingMember" : {"_about" : "http://data.parliament.uk/members/301", "label" : {"_value" : "Biography information for Richard Burden"} } , "tablingMemberConstituency" : {"_value" : "Birmingham, Northfield"} , "tablingMemberPrinted" : [{"_value" : "Richard Burden"} ], "uin" : "34806"} , {"_about" : "http://data.parliament.uk/resources/470539", "AnsweringBody" : [{"_value" : "Department for Transport"} ], "answer" : {"_about" : "http://data.parliament.uk/resources/470539/answer", "answerText" : {"_value" : "
In 2015 more ultra low emission vehicles were registered in the UK than in the previous four years combined. The total number of new registrations of ultra low emission vehicles in each year from 2010 to 2015 is published online, and shown in the following table.<\/p>
