This is one in a series of papers exploring the implications of a 55% by 2035 interim emission reduction target proposed by the AEC. This paper looks at the opportunities for emissions reduction in transport. As with many other emitting activities there are multiple ways to reduce emissions from transport. However, with the ultimate goal of net zero in mind, options that decarbonise the fuel source are preferable in the long-term over options that can only make marginal reductions.
