Background
In 1998-99, to control greenhouse gas (GHG) emissions from the transportation sector, the European Commission signed voluntary agreements with the automotive industry to reduce the emissions of carbon dioxide (CO2). Since 2008-09—when regulations were adopted to control CO2 emissions from new light-duty vehicles—the voluntary agreements described in this article are no longer binding, and have only historical significance.
Three agreements were signed in 1998-99, with the following associations:
- ACEA—European Automobile Manufacturers Association (Association des Constructeurs Européens d’Automobiles): BMW, DaimlerChrysler, Fiat, Ford, GM, Porsche, PSA Peugeot Citroën, Renault, VW Group.
- JAMA—Japanese Automobile Manufacturers Association: Daihatsu, Honda, Isuzu, Mazda, Mitsubishi, Nissan, Subaru, Suzuki, Toyota.
- KAMA—Korean Automobile Manufacturers Association: Daewoo, Hyundai, Kia, Ssangyong.
Cars sold by the above companies represented about 90% of the total EU vehicle sales.
The agreements defined fleet-average CO2 emission targets from new cars sold in the European Union, to be reached collectively by the members of each association. Carbon dioxide was the only gas covered by the agreements, other climate change emissions were not controlled.
ACEA Agreement
The ACEA Agreement, signed in March 1998, included the following major provisions:
- CO2 emission target of 140 g/km to be reached by 2008 (this target represented a 25% reduction from the 1995 level of 186 g/km)
- Possibility to extend the agreement to 120 g CO2/km by 2012
- Intermediate target range of 165-170 g CO2/km by 2003
- Individual ACEA members to introduce models of 120 g CO2/km or less by 2000
The limits applied to the collective ACEA members’ fleet of new passenger cars (Category M1) produced or imported into the European Union. CO2 emissions were measured over the NEDC test.
Japanese and Korean manufacturers (JAMA and KAMA) signed similar commitments to that of ACEA, with the following differences:
- JAMA and KAMA target of 140 g CO2/km was delayed by one year, to 2009
- JAMA had a wider 2003 intermediate target range of 165-175 g CO2/km
- KAMA intermediate target of 165-170 g CO2/km was delayed by one year, to 2004
The emission targets were to be met through technological advancements leading to increased fuel economy. The Commission estimated that the compliant fleet of passenger cars in 2008/09 would consume on average about 5.8 l gasoline/100 km or 5.25 l diesel/100 km. The CO2 agreements were an important factor driving the increased dieselization of the passenger car market in the EU.
Progress Monitoring
Progress toward the CO2 emission targets was monitored jointly by the European Commission and by ACEA. Annual progress reports were published by the Commission. ACEA progress through 2003 is illustrated and compared with the targets in Figure 1.

CO2 emission figures for 2003 are listed in Table 1.
| CO2 in 2003 | Reduction since | Interim target | ||||
|---|---|---|---|---|---|---|
| Total | Gasoline | Diesel | 1995 | 2002 | ||
| ACEA | 163 | 171 | 154 | 11.9% | 1.2% | 165-170 (2003) |
| JAMA | 172 | 170 | 177 | 12.2% | 1.1% | 165-175 (2003) |
| KAMA | 179 | 171 | 201 | 9.1% | 2.2% | 165-170 (2004) |
| EU-15 | 164 | 171 | 157 | 11.8% | 1.2% | - |
While significant CO2 emission reductions were achieved in the initial years, none of the three associations was able to reach the 140 g/km target by 2008/09. The fleet-average CO2 emissions in 2009 were at about 160 g/km, 20 g above the target. In 2009, the voluntary agreements were replaced by mandatory CO2 emission regulations from new light-duty vehicles.
