JAMA members pursue their efforts towards CO2 reductions

On 29 August 2006, the European Commission published its sixth annual report on its "Strategy to Reduce CO2 Emissions from Cars".  The voluntary commitments by ACEA, JAMA and KAMA to reduce CO2 emissions from new passenger cars to an average of 140g/km by 2008 (for European manufacturers) and 2009 (for Japanese and Korean producers) represent the key element of this European CO2 strategy.

In 2004, JAMA members reduced the average specific CO2 emissions from their new passenger cars sold within the EU by about 2g/km, to 170g/km.  Compared to 1995, this represents a 13.2% decrease in average specific CO2 emissions, a positive step towards the 140g/km target.  The Commission also confirms that ACEA, JAMA and KAMA have, during the period 1998 to 2004, met all of their obligations as set out in their voluntary commitments.

The 2004 monitoring report shows that JAMA is fully in line with its 2009 commitment.  Indeed, JAMA members are actively pursuing the introduction of fuel-efficient vehicles.  In 2004, a total of 114,826 new vehicles emitting 120g CO2/km or less were registered, representing a 65% increase compared to 2003.

To achieve the CO2 emission target agreed to in its 2009 commitment, JAMA will further explore various technologies including direction injection (DI), hybrid engine and Continuous Variable Transmission (CVT) technologies. JAMA emphasizes the difficulty of planning and managing CO2 reduction due to unknown factors such as changing consumer demands.

JAMA also stresses that the 2009 target remains extremely ambitious, both technically and economically.  In order to reach that target, annual emissions reductions will have to increase to an average reduction rate of around 3.5% per year over the period until 2009.

JAMA asserts, too, that meeting the further target of 120g CO2/km cannot be achieved through the efforts of automobile manufacturers alone.  Instead, an integrated approach is required, one that will bring together vehicle manufacturers, governments and vehicle users.  Such an approach must include elements such as CO2-related vehicle taxation and tax incentives to encourage consumers to buy “greener” models.  Japanese manufacturers also support the development of eco-driving and gearshift indicators, since previous studies have established their beneficial role in CO2 reduction.

The reduction of CO2 emissions is also dependent on the availability of high-quality fuels.  JAMA believes that better-quality fuels should therefore be supplied in accordance with the specifications of the World-Wide Fuel Charter adopted by JAMA, ACEA, the Alliance, and EMA, in order to enable vehicle manufacturers to incorporate new technologies in their products.

JAMA urges the European Commission to consider the significant efforts that are being made by all actors to reduce CO2 emissions from motor vehicles and to acknowledge the particular difficulties that manufacturers face in meeting their respective targets.
