This white paper evaluates the response to fiscal incentives in 2013 to incentivise the purchase of plug-in electric vehicles in major vehicle markets around the world. It synthesises sales data, national taxation policy information, and direct electric vehicle purchasing rebates to analyse the link between government policy and electric vehicle sales. It does so by focusing on two representative vehicles, the Renault Zoe battery-electric vehicle (BEV) and the Volvo V60 plug-in hybrid electric vehicle (PHEV). The paper identifies markets with varying market growth in electric vehicles and quantifies the taxation difference between electric vehicles and their conventional, non-electric counterparts. It incorporates fuel and electricity prices to evaluate the equivalent total cost of ownership. Finally, the paper links the level of incentives to the level of  electric vehicle market share and sales growth, seeking to draw conclusions about the  impact of different incentive programs.
