The Agreement specifies how regulations are to be established and how the system operates whereby an approval under a given regulation accorded by one country can be accepted by all other countries applying that regulation. The program to establish an international system for whole vehicles (as opposed to the current focus on individual vehicle components and systems) includes an important restructuring of the 1958 Agreement. Revision 3 of the 1958 Agreement enters into force on 14 September 2017. 1958 Agreement 1958 Agreement United Nations Agreement 1958 Agreement, Agreement concerning the establishing of global technical regulations for wheeled vehicles, equipment, and parts which can be fitted and/or be used on wheeled vehicles The 1998 Global Agreement provides the framework for establishing UN Global Technical Regulations. Under the Agreement, the World Forum maintains a Compendium of Candidates listing national and/or regional regulations proposed by Contracting Parties as possible bases for the development of Global Technical Regulations. Items remain on this list for five years unless renewed by request of a Contracting Party. 1998 Agreement 1998 Global Agreement United Nations Agreement 1998 Global Agreement, Global Technical Regulation No. 4: Test Procedure for Compression-ignition (C.I.) Engines and Positive-ignition (P.I.) Engines Fuelled with Natural Gas (NG) or Liquefied Petroleum Gas (LPG) with regard to the Emission of Pollutants The Informal Group on Heavy-Duty Hybrids expects to deliver its final draft amendment to GTR No.4 at the January 2014 session of GRPE. This amendment would extend GTR No. 4 to include test procedures to evaluate hybrid heavy-duty vehicles.

This effort aims to establish an amendment to Global Technical Regulation (gtr) No. 4 (WHDC) with respect to pollutant and CO2 emissions from heavy duty hybrids. The initial focus is on a Hardware-in-the-Loop (HILS) approach, which starts from the vehicle speed pattern of the WHVC vehicle cycle and simulates powertrain and vehicle components to result in a hybrid specific engine cycle for pollutant emissions and CO2 testing and measurement, and which allows using the test cell environment, data evaluation procedures and emissions calculations specified in gtr No. 4. This effort may lead to a second phase to establish a chassis dyno test procedure, as an alternative to HILS, which would involve specifying new requirements with respect to test cell environment, data evaluation procedures and emissions calculations. The informal group developing this regulatory language expects to finalize its work in March 2013 for GRPE review the following June (setting the stage for possible WP.29 adoption in November 2013 or March 2014).
