Within the next ten years, passenger car travel is projected to double across the ten Member States of the Association for Southeast Asian Nations (ASEAN) (IEA 2012a). By 2025, sales of passenger cars are estimated to be well above 3 million cars per year, from about 1.5 million in 2015 (OICA 2016). With increasing car ownership but overall still low motorisation levels in ASEAN, it is realistic to expect substantial further growth in motorisation, along with growth in fuel consumption and emissions of CO and other pollutants. As a result, stepping up fuel economy policy efforts is vital for making these growth trends compatible with climate change efforts, including towards urban air quality and the need for resource efficiency.

Sustainable transport has been identified as a fundamental pillar of ASEAN’s regional transport agenda under the Kuala Lumpur Transport Strategic Plan 2016-2025 (KLTSP). Energy efficiency of transportation is a key aspect of the plan’s Sustainable Transport Strategic Goal, making fuel economy policy a priority for cooperation and implementation across the region.
