To fuse these strands into a critical mass and promote active engagement with the farming community, the Commission's agriculture and environment services will jointly establish an agriculture platform as part of the European Clean Air Forum (see section 5.1 below).

(7) In order to achieve EU air quality objectives and to ensure a continuous effort to reduce vehicle emissions, the power to adopt delegated acts in accordance with Article 290 of the Treaty on the Functioning of the European Union (TFUE) should be delegated to the Commission in respect of the detailed rules on the application of Regulation (EC) No 715/2007 to vehicles of categories M1, M2, N1 and N2 with a reference mass exceeding 2 610 kg but with a maximum vehicle mass not exceeding 5 000 kg, the specific procedures, tests and requirements for type approval, the requirements for the implementation of the prohibition on the use of def ...[+++]eat devices that reduce the effectiveness of emission control systems, the measures necessary for the implementation of the obligation of a manufacturer to provide unrestricted and standardised access to vehicle repair and maintenance information, the replacement of the information on the mass of CO2 emissions in the certificate of conformity with information on total mass of CO2 emissions equivalents, the increase or removal of the limit value of total hydrocarbons emissions for positive ignition vehicles, the amendment of Regulation (EC) No 715/2007 for the purposes of recalibrating the particulate mass based limit values and introducing particle number based limit values that would correlate broadly with the petrol and diesel mass limit values, the adoption of a revised measurement procedure for particulates and a particle number limit value, a limit value for emissions of NO2 and limits for tailpipe emissions at cold temperatures for vehicles approved as complying with the Euro 6 emission limits.

In addition to the quantitative risk, the extraction and use of natural resources may reduce the quality of the natural environment (such as the atmosphere, bodies of water, soil) in a way that threatens ecosystems, in particular by destroying habitats or causing the extinction of certain species, or human health (e.g. through exposure to harmful substances such as asbestos).

The reference method for the measurement of arsenic, cadmium and nickel concentrations in ambient air is currently being standardised by CEN and shall be based on manual PM sampling equivalent to EN 12341, followed by digestion of the samples and analysis by Atomic Absorption Spectrometry or ICP Mass Spectrometry.
