§ Simon Hughes
To ask the Secretary of State for Transport what plans he has to introduce statutory regulation on emissions from(a) motorcycles and (b) powered two-wheel vehicles. 
§ Mr. Jamieson
Emissions from new motor cycles and other powered two wheeled machines are already regulated by the Motor Cycles Etc (EC Type Approval) Regulations 1999 (S.I. 1999 No. 2920) as amended by The Motorcycles Etc. (EC Type Approval) (Amendment) Regulations 2003. The former mandates the emissions standards in EU directive 97/24/EC to be met by all new machines entering service from 17 June 2003. The 2003 regulations mandate the more stringent two stage standards in EU directive 2002/51/EC for new motorcycles entering service from 1 July 2004 and from 1 January 2007.
