Final report
Publication metadata
The objective of this study was to suggest a proper testing methodology for measuring CO2 emissions savings from innovative Mobile Air Conditioning (MAC) technologies, in the context of the EU eco-innovations scheme under Regulation (EU) 2019/631. Additionally, the study aimed to provide support to the European Commission in preparing a possible adjustment of the 7 g CO2/km cap on eco-innovation credits and examining the level of eco-innovation savings that may be attained by MAC systems. In order to propose an exhaustive methodology, this study assessed what is a baseline MAC system. Thanks to an extensive market survey and literature review, a baseline MAC system was identified and defined in a technologically neutral way. Therefore, any MAC technology would potentially be eligible for credits, as long as it proved to be sufficiently more efficient than the defined baseline. To minimise the testing burden, a combination of simulations and vehicle testing is suggested. One test is suggested for the vehicle equipped with the innovative technology, which is based on type 1 testing, as described in UN Regulation 154. The differences with the type 1 test are the different ambient conditions of testing and the requirement for the MAC system to be on. Taking into account the technological advancements of MAC systems and the methodology proposed, the possible revision of the eco-innovation cap has been considered and the maximum CO2 credits that could be obtained from MAC systems has been estimated. For the latter, various scenarios with increased MAC system efficiency in comparison to the baseline were examined.
