COMMISSION
DIRECTIVE 1999/100/EC

of
15 December 1999

adapting
to technical progress Council Directive 80/1268/EEC relating to

the
carbon dioxide emissions and the fuel consumption of motor vehicles

(Text
with EEA relevance)

THE
COMMISSION OF THE EUROPEAN COMMUNITIES,

Having
regard to the Treaty establishing the European Community,

Having
regard to Council Directive 70/156/EEC of 6 February 1970 on the

approximation
of the laws of the Member States relating to the type-approval

of
motor vehicles and their trailers ( 1 ), as last amended by Directive 98/91/EC

of the
European Parliament and of the Council ( 2 ), and in particular Article

13(2)
thereof,

Having
regard to Council Directive 80/1268/EEC of 16 December 1980

relating
to the carbon dioxide emissions and the fuel consumption of motor

vehicles
( 3 ), as last amended by Commission Directive 93/116/EC ( 4 ), and in

particular
Article 3 thereof,

Whereas:

(1)
Directive 80/1268/EEC is one of the separate Directives of the EC

type-approval
procedure which was established by Directive

70/156/EEC.
Consequently, the provisions laid down in Directive

70/156/EEC
relating to vehicle systems, components and separate

technical
units apply to this Directive.

(2) In
Directive 98/69/EC of the European Parliament and Council of 13

October
1998 relating to measures to be taken against air pollution

from
motor vehicles and amending Council Directive 70/220/EEC ( 5 ),

the
type I test cycle for emission measurement was amended by

abolishing
the initial 40 seconds of engine idle time. It is necessary to

align
the test cycle for the measurement of CO2 emissions and fuel

consumption
in Directive 80/1268/EEC accordingly.

(3)
With a view to the monitoring of CO2 emissions in the framework of

the
Community strategy to reduce CO2 emissions of passenger cars, it

is
appropriate to introduce into Directive 80/1268/EEC new technical

requirements
regarding the measurement of CO2 emissions and fuel

consumption
for the EC type-approval of gas-fuelled vehicles (LPG

and
NG). In this respect, it is appropriate to follow the technical

requirements
adopted by the United Nations Economic Commission

for
Europe in its Regulation No 101 ( 6 ).

(4) The
measures provided for in this Directive are in accordance with the

opinion
of the Committee for Adaptation to Technical Progress

established
by Directive 70/156/EEC,

HAS
ADOPTED THIS DIRECTIVE:
